FOREWORD

Dear Members of 17th Colloquium “Sustainable Decisions in Built Environment” and meet-ing of EURO working group ORSDCE - Operation Research in Sustainable Development and Civil Engineering

It is a great pleasure to address you some introductory words and present the last year achievements. The 17th Colloquium held on May 15, 2019 in Vilnius, Lithuania is organizing with aim to gather a wide audience for promoting the ideas of international collaboration in areas of operations research and sustainable development. We also aiming to present the results of more than 30 years of scientific collaboration and discuss the further activities.

Last year was rich in scientific events were members of EWG-ORSDCE have participat-ed. The years 2017-2018 were signified by appearance of new optimization methods: Com-bined Compromise Solution (CoCoSo), Simultaneous evaluation of criteria and alternatives (SECA), ARCAS approach based on the integration of the SWARA and the ARAS methods, the pivot pairwise relative criteria importance assessment method (PIPRECIA), comparative analysis of weight balancing method (WEBIRA).

Implementing and aррlying these new-born techniques not only increases the aссuracy of the decision-making, but also aids company policies, accredits the global objectives, and delivers the beneficial сonsequenсes to the management control. Methods have a promising future in the construction engineering field, because offer a highly methodological basis for decision support.

We are proud to announce that active members of EWG-ORSDCE published several successful Special Issues in different Clarivate Analytics Web of Science journals and cur-rently some more issues are open for submissions in journals related to the research field of our Working Group.

We are pleased to announce the launch of our new website that aims to create a us-er-friendly browsing experience for our trusted and valued members and the scientific com-munity. The new website of EWG ORSDCE can be accessed using this link: https://www.euro-online.org/websites/orsdce/

Finally, I should remind that the aims of EURO Working Group “Operations Research in Sustainable Development and Civil Engineering” are not only to develop and apply the mul-tiple criteria methods, but also to promote the innovations based on application of multiple criteria methods in construction industry; to facilitate the collaborations between European researchers working in field of OR in civil engineering and sustainable development and to ensure the transfer for scientific communities and construction industry the ideas of multiple criteria decision aiding, thoughts and important results of discussions.

17th Colloquium

THE QUANTIFICATION OF MULTI-CRITERIA DECISIONS

Friedel Peldschus

Leipzig University of Applied Sciences, Leipzig, GermanyE-mail: [email protected]

Numerical values are needed for the quantification in the description of complex processes. It is important and of interest, how the needed values shall be calculated. In other words: What shall for instance be measured to characterise an economic value? The focus is there-by on the accuracy and the robustness of the derived solutions rather than on the dominance of numerical values themselves. As a result, the quality of the processes is transformed into quantitative measures. The initial and boundary conditions are crucial therein. Many meth-ods have been developed for the solution of problems in multi-criteria decisions in the last decades. Different ideas are the basis for those methods. For this reason, it cannot be ex-cluded that for a specific problem different solutions are calculated depending on the method chosen. Sometimes many mathematical operations are performed in the application of those methods. The effect of the mathematical operations cannot anymore sufficiently assessed in this complexity. Hence, it is barely possible to assess the quality of the solutions. Even if a numerical result is derived in each case, a selection is required in the application of several methods. Unfortunately, there is no recommendation for this to date. As a work-around, the statistical frequency of the results is used as a judgement of the quality of the solution. It is noteworthy that statistical calculations with wrong numbers are not expected to lead to a correct result. In order to derive significant results, it is necessary to critically analyse the sin-gle methods. It can thereby be noticed that the first errors are observed in the calculation of the initial values, preventing the derivation of correct results as errors occurring in the initial values cannot be compensated by subsequently applied solution methods.

For the description of multi-criteria decision problems, the comparative effectiveness of alternatives is expressed in dimension-less values. This is referred to as normalisation of characteristic values. The normalisation leads to transformation of the values to the interval

[1 ; 0] or [1 ; ~ 0] using linear and non-linear functions. It was observed that linear func-tions allow a good mapping to the interval [1 ; 0]. Problems arise however in minimisation with values greater than two-fold the minimal value. Here, other functions need to be used. An alternative is using non-linear functions. It needs to be noted that any non-linear function will deform the original problem. If the selected non-linear function corresponds to the origi-nal course of the function, this is seen as an acceptable approximation, and could even lead to the amplification of the intended optimisation trend in an additional effect. Convex as well as concave functions are applied, and significant differences in the calculated values can be observed. As those values are used in the solution procedures for multi-criteria decision together with different numerical methods, differences in the results occur, even with un-changed methods.

11


10 formulae for the determination of dimensionless values are analysed, and the impor-tance of convex and concave course of the functions used is discussed. Three cases are to be distinguished in the selection of appropriate transformation formulas: Maximization problems, minimization problems and a simultaneous consideration of maximization and minimization. The optimization objective is crucial for the selection of a suitable transfor-mation formula, as the required conditions differ. Only addressing maximisation, a linear transformation can be adequately applied. For minimisation problems, a distinction needs to be made between cases, in which the value range is within the two-fold minimum, and cases considering values exceeding the two-fold minimum. If the latter is the case, a non-linear transformation needs to be applied. As the application of a non-linear transformation leads to a deformation of the original problem, it is essential to analyse the function profile in addition, thereby identifying an either convex or concave profile of the function. Omitting this analysis potentially causes further deformations and a flawed result. Furthermore, if maximisation and minimisation need to be addressed simultaneously for the problem to be solved, then it needs to be assured, that an unintended weighting between maximization and minimization is prevented.

The author targets the Game Theory equilibrium for the calculation of an optimal solution. Therein, the calculation of an equilibrium point includes the evaluation of variants as well as the evaluation of criteria. This information may prove to be very beneficial in the application of the derived result.

The meetings at various conferences, mainly in the former GDR (Weimar, Leipzig) in the 1970s, finally resulted with an idea of Professor Edmundas K. Zavadskas to form a group, which would meet as part of the Colloquium. The group consisted of academic teachers representing three universities: Vilnius, Leipzig, and Poznań. Later, colleagues from other centres and other countries joined us. We were hungry of knowledge, eager to exchange information; we needed to compare our achievements and to start cooperating in the area of research.

There were also specific technical and political conditions for this cooperation; it was a low budget exchange, there was no Internet at the time. The first colloquium took place in Leipzig in 1986. Then, alternately, in the academic centres of the three countries. From the very beginning, the Lithuanian centre preferred multi-criteria methods, our colleagues from Leipzig applied game theory, and Poznań focused on the theory of reliability. In general, we tackled with the decision-making theory, and planning instruments for the organization of construction processes. Over time, the subject matter evolved from the level of production processes to the level of project and the enterprise. In particular, MCDM methods developed remarkably well, new methods appeared based on fuzzy numbers, grey numbers, as well as verbal and hybrid methods. Currently, elements of such areas as biometric, neutrosophic and neuro design are also clearly articulated.

We were given an opportunity to present not only our own achievements but also to conduct joint research and conclude joint publications. We had access to periodicals from these countries. Finally, we were able to publish in Lithuanian journals, which listed on the so-called Philadelphia list. Particularly noteworthy is mutual help in promoting PhD and post-doctoral dissertations and, primarily, in reviewing.

All this flourished in achievements, which are impressive in terms of numbers. Several hundred articles and dozens of books are irrefutable proof of the above.

The leaders of the three academic centres granted the titles of doctor honoris causa: Professor F. Peldschus (1991) and Professor O. Kapliński (1996) in Vilnius, and Professor E.K. Zavadskas in Poznań (2002). Polish and Lithuanian parliamentary committees widely appreciated this cooperation: E. K. Zavadskas was distinguished by the Presidium of the

13


Parliamentary Assembly of the Sejm of the Republic of Poland and the Seimas of the Re-public of Lithuania with the “Prize of the Two Nations” (2004).

Cooperation has always been in the spirit of integral humanism and continues without a trace of xenophobia.

This year’s Colloquium is 17th in a row, marking 33 years of formal cooperation. After the political and economic transformations, joint work has not stopped, though the condi-tions have changed, so there was a need for another form of mutual effort, i.e. organized within the EURO Working Group. The idea of Colloquia is now in the hands of the young academics, and ought to be addressed to them. It should be a platform for their first scientific confrontations. Nonetheless, we would appreciate if the Methuselahs of this beautiful idea were not forgotten.

EURO WORKING GROUP ACTIVITIES PROMOTING THE IDEAS OF OPERATIONS RESEARCH IN AREAS OF CIVIL ENGINEERING AND

SUSTAINABLE DEVELOPMENT

The important role in the future development of the construction industry will have the ap-plication of new techniques and methods, which could raise the efficiency of processes. Traditional optimization, statistical and econometric analysis approaches used within the en-gineering context are often based on the assumption that the considered problem is well for-mulated and decision-makers usually consider the existence of a single objective, evaluation criterion or point of view that underlies the conducted analysis. In such a case, the solution of engineering problems is easy to obtain. However, in reality, the modelling of engineering problems is based on a different kind of logic taking into consideration the conflicting aims of decision makers, the existence of multiple criteria, the complex, subjective and different na-ture of the evaluation process. Therefore, multiple criteria methods contribute to engineering context through the identification of the optimal alternatives taking into account the conflicts between the criteria and revealing the preferences.

Emphasizing the importance of aforementioned issues and striving to contribute to re-solving the conflicts between the various competing goals in pursuit of economic prosperity, environmental quality and technological efficiency the EURO Working Group “Operations Research in Sustainable Development and Civil Engineering” (hereinafter - Working Group) raises the following objectives:

– to develop and apply the multiple criteria methods in the fields of sustainable devel-opment and civil engineering;

– to promote the innovations based on the application of multiple criteria methods in the construction industry;

– to facilitate the collaborations between European researchers working in the field of OR in civil engineering and sustainable development;

– to ensure the continuity and progress of work and to transfer for scientific communities and construction industry the ideas of multiple criteria decision aiding, the results of work, thoughts and important discussions of group members.

The fields of the research concentrate in three broad fields: Operational Research, Civil Engi-neering and Sustainable Development. On top of that, the primary purpose of the Working Group is to stimulate collaboration in the area of OR in sustainable development and civil engineering.

IT IS ALL ABOUT DECISION MAKING: FROM PROPERTY VALUATION TO BUILT ENVIRONMENT AND LAND MANAGEMENT

Traditionally Multiple Criteria Decision Making (MCDM) methods have been widely used in Business Management and Civil Engineering. However, in recent years the MCDM methods have been successfully applied in various topics of Real Estate, Land Management and Built Environment related research. The turn of the 21st century marks significant changes and development processes in land - real estate management and valuation, which are being constantly affected by legal, economic and social conditions. Stakeholders are constantly facing a pressure on decision making for sometimes very complex projects.

MCDM methods deal with the evaluation of set of alternatives in terms of numerous, often conflicting, decision criteria (Triantaphyllou 2000). Thus, given set of alternatives and number of criteria, MCDM aims to assist in identifying the best alternative or ranking of the alterna-tives. MCDM methods are useful in supporting decision making problems where conflicting objectives are involved, especially economic, environmental, social, and politic (Maliene, 2010, 2011; Maliene et al., 2018; Mulliner et al., 2013, 2016; Prochorskaite et al., 2016).

Several recent MCDM methods’ applications in land and property management research and practice will be introduced during the presentation.

This paper endeavours to measure the consistency of a decision-making tool, popularly known as Best Worst Method (BWM), which is one of the latest developments in multiple-cri-teria decision analysis (MCDA). BWM is finding a vast area of applications in the literature. Several investigators have extended this tool. BWM measures the weight of decision-mak-ing criterion and is recognized as a subjective decision tool. The first step in this method is to find the best and worst criterion, while we suppose several experts are asked to present their evaluation over set of criteria. The aim is to measure how these judgments are consis-tent and reliable. So, we statistically (using χ2 distribution) add a pre-evaluation to experts’ opinion and analyse whether the agreement of experts’ opinions is satisfactory and group opinion is established. This action improves the quality of the decision-making process by incorporating the reliability evaluation of experts’ idea. This extension for BWM assists deci-sion makers in facilitating and getting results that are more consistent for criteria evaluation. We present examples in sustainable construction and architecture project.

Construction is one of the branches of the economy where innovation is slowly on the road. New materials, structures and their technologies must be well researched, described and tested in practice. Also, change has both positive and negative features. Only in exceptional cases can some alternatives are the best in terms of all the criteria evaluated. Therefore, the model should consider trade-offs between the criteria values and the interests of the group members when evaluating such alternatives. Also, further information describing such options cannot be accurate in advance. Unnecessary models for justifying decisions are needed. The authors of this study have developed and presented an original model, which consists of four multi-criteria assessment methods: ARAS-F (additive multi-criteria utility function form), EDAS-F (deviations from average solution in Euclidean space), Geometric mean (GEM) and SWARA (Step-Wise Ratio Analysis) weighing method). The article pro-vides a real example of a task solution.

The authors set the main goals of the group’s investors, set the list of efficiency criteria, set the weights and values of the requirements.

During the last decade, a lot of the research efforts have been made to incorporate the vagueness of the initial information for the solution of the complex nature practical prob-lems by multi-criteria decision making (MCDM) methods. A theory of the neutrosophic sets recently proposed by Smarandache allows dealing with “knowledge of neural thought”. By the logic of the neutrosophic sets, each aspect of the problem is represented by the degree of the truth (T), a degree of the indeterminacy (I) and a degree of the falsity (F). The exten-sions of Lithuanian Trend of MCDM Methods, such as COPRAS, WASPAS, MULTIMOO-RA, to the neutrosophic set environment are presented. All neutrosophic extensions consist of the following steps: neutrosophication, solution of MCDM by the operational algebra of the neutrosophic sets, de-neutrosophication. For the execution of the de-neutrosophication step, a new version of the score function is proposed. COPRAS method extension by the single-valued neutrosophic set, namely COPRAS-SVNS, has been applied for the selection of a location for a liquefied natural gas terminal at east Baltic sea. A neutrosophic extension of WASPAS method, namely WASPAS-SVNS, has been successfully applied to solve waste incineration plant siting problem due to the requirements of sustainability factors, the location selection problem of the garage at the parcel of a single-family residential house. A neutro-sophic extension of MAMVA method was dedicated to handling market value calculations by solving multiple criteria assessment problems, thus aggregating all necessary kinds of the information into a single measure. The new neutrosophic extension of the MULTIMOORA method, namely MULTIMOORA-SVNS, allows taking into assessment the indeterminacy of the initial decision making information in a single-family residential house materials’ and elements’ selection problem.

Both weights of criteria and statistical numbers, elements of the decision-matrix, that de-scribe evaluated objects (alternatives) make a considerable effect on the results of an eval-uation by the MCDM (multiple criteria decision-making) methods. Subjective weights elicited from experts are used more often, while objective methods that reflect the structure of data are also commonly used. Among the latter, the most frequent is the entropy method, which conveys the degree of domination of statistical values to the estimated weights. The entropy method has shortcomings; they can affect the results of the multiple criteria evaluation. It was previously noted that in cases when differences between values of criteria appear to be inconsiderable the corresponding entropy weight becomes closer to nil. In contrast, the CILOS method determines the relative impact loss experienced by a criterion of an alterna-tive, when another criterion is chosen to be the best. Thus, the latter method compensates the shortcomings of the entropy method and can be successfully combined into the IDOCIW method, by which the integral weights are calculated.

By comprising uncertainty and fuzzy numbers (Zadeh 1965; Triantaphyllou 2000). to the relative impact loss method CILOS, and to the integrating weights method IDOCRIW, which was previously created by the authors (Zavadskas, Podvezko 2016), the new methods FCIL-OS and FIDOCRIW are proposed and described in this paper. It is worth noting that a formal transformation of deterministic mathematical methods for making them fuzzy, is impossible. Features of fuzzy methods and related problems in the usage of these methods are revealed. Fuzzy numbers are applied to the mentioned above deterministic methods, and thus fuzzy weights are found. Such weights allow to comprehensively investigate the structure of the fuzzy decision matrix, to use MCDM fuzzy methods, to comprise subjective and objective weights, and to obtain the cumulative fuzzy weights in the environment with uncertainty.

TEXTILE REINFORCED CONCRETE FOR SUSTAINABLE CONSTRUCTION

Klaus Holschemacher

Structural Concrete Institute, Faculty of Civil Engineering, HTWK Leipzig, Leipzig, GermanyE-mail: [email protected]

Sustainability topics and measures for the reduction of carbon dioxide emissions gain steadi-ly importance in civil engineering. In this context, the concrete industry has to improve the durability of their products and to look for possibilities to avoid corrosion of steel reinforce-ment. Within the last 50 years, in normative regulations, the required concrete cover was essentially increased. Another practice was the application of corrosion-resistant metallic reinforcement that is quite expensive.

A newer tendency is the utilization of textile reinforced concrete (TRC), especially for precast concrete members. The basic idea for the development of TRC was the intention to replace the traditional steel bar or steel mesh reinforcement by textile meshes based on alkali-resistant glass fibres, carbon fibres or in few cases basaltic fibres. By this method, it is possible to avoid the corrosion problem of the steel-based reinforcement and to improve the durability of precast concrete members. However, there was not a real break-through of TRC in construction practice until 2015. The main reason was the favoured application of glass fibres production of textile reinforcement and the limited load-bearing capacity of TRC members.

The recent step in the development of TRC is the application of carbon fibres for the production of textile mesh and bar reinforcement. Carbon meshes and carbon bars may be used combined or separately as reinforcement resulting in a new construction material called carbon concrete composite. Based on the outstanding properties of carbon fibres it is possible to enhance essentially the application possibilities of TRC. The paper describes the basics of the production and approaches for the design of carbon concrete composite members and reports the first applications in construction practice.

The aim of this article is to present the application of Monte Carlo Simulation in the life-cycle costing understood as “methodology for the systematic economic evaluation of life-cycle costs over a period of analysis”. The article is limited to maintenance cost including a total of necessary labour, material and other related costs incurred to retain a building or its parts in a technical condition in which it can perform its required functions.

The analysis presented in the article may be used in all four key stages of the life cycle of a building, however, in particular, to the first two stages, i.e.: project investment and planning (WLC/LCC strategic options analyses; preconstruction) and design and construction (LCC during construction, at scheme, functional, system and detailed component levels).

A wide range of maintenance types, activities and frequencies can have different costs and effects on the ongoing performance and future replacement cycles of a constructed asset. The level of risk associated with the LCC analysis depends primarily on such issues as the quality and scope of data available and pricing assumptions. The risk level depends on the method of the calculation as well, however, undoubtedly, the later period of life-cycle of a building, the higher risk of maintenance cost calculation causes.

In the presented article, there was prepared the analysis of future maintenance costs basing on the example of a retail store building used by the trading company. In the Monte Carlo analysis, triangular probability distributions (indicated in the literature as appropriate to account for uncertainty in valuation processes) were used. The analysis (in which the Crystal Ball technique was used) allowed the identification of a distribution of possible costs and a range of more and less probable figures for use in calculations. Interpretation of the results of the Monte Carlo Simulation summarizes the use of the applied methodology.

Keywords: Monte Carlo Simulation, life-cycle costing, maintenance

BIG DATA IN CONSTRUCTION – TEXT MINING ANALYSIS OF SELECTED DATA SOURCES

Marcin Gajzler

Institute of Structural Engineering, Poznan University of Technology, 60-965 Poznań, PolandE-mail: [email protected]

Nowadays many organizations have a large number of data resources, the analysis of which underlies the success of these organizations. It is connected with the progressive digital revolution, in the course of which all activities of participants of systems or economic phe-nomena are registered. In the construction industry, there are sources of a large number of data, the analysis of which gives the opportunity to achieve the maximizing effect. A kind of new class of data sources are systems based on BIM, which will ultimately collect data and information about the object in its life cycle. The topic is focused on text sources. In contrast to quantitative sources, there is a potential difficulty in the analysis of text data, because they need to be familiarized and interpreted first. Analysis of text sources without the use of assistive techniques is usually laborious. A helpful tool in this situation is text mining analysis.

As part of the work, 68 books of the building object with attached protocols from periodic inspections and checks were analyzed. The set of 68 books is not yet typical big data, but the amount of data contained there requires the assisted analysis. However, it should be noted that property managers and administrators often manage a larger number of buildings, which allows defining the building data resource as big data. The analysis of text mining was carried out without the basic process of the word, which resulted from software limitations. Then, the process of the word was carried out, resulting primarily in a reduced dimension of the BOW result matrix. In addition to the reduction in the size of the matrix, a more complete representation of the text document was also obtained. Unless the BOW process [385x68] was obtained without the process of the wording, the reduced dimension to [181x68] was obtained after the use of the word process. Such a reduction already facilitated the process of further analysis, in the course of which other methods of reduction were used, e.g. the decomposition to singular values (Singular Value Decomposition).

The article indicates the advantages of a flexible approach implemented in concreting op-eration at cold weather. Special quality problems resulting from the turbulent impact of the surrounding environment occur during the concreting at low temperature, when the concrete structure may be damaged due to sudden concrete freezing. The proposed approach is based on sequential decision making assuming a gradual update of the decision situation in three main stages: (1) decision on the term of concreting, (2) selection of the mixture (includ-ing options of active and passive flexibility), (3) activation of the active flexibility option in the event of a pessimistic scenario. The simulation of the thermal field in the concrete element plays an important role, which allows estimating the risk of damage of the concrete structure taking into account the destructive stresses related to freezing water and tracking the matu-ration of fresh concrete (frost resistance). The comparative analysis shows the advantages of using forecasts with more frequent database updates. The method is illustrated by an example of a sealed slab at a petrol station, when the risk of quality defects may mean that it needs to be demolished and rework. The conclusions indicate the prospects for a flexible approach based on synergy achieved with the simultaneous use of real-time monitoring, regularly updated weather forecasts and simulation of processes in maturing concrete.

The current situation in the construction market is very difficult. Lower productivity in con-struction compared to production indicates a significant potential for improvements in con-struction processes, which until now has not been fully used.

An important role in the national and global economy, not only in the aspect of construc-tion production, is played by companies from the SME sector. It is advisable and fully justified to focus on this because of three important reasons:

– The SME sector in the European economy has a high position related to participation in the creation of PKD.

– SMEs have a significant share in creating jobs on the labour market because in Po-land 69%, and 67% in Europe, all available places are created in the sector described

– In Poland since 2013. there is an annual increase in the number of micro-enterprises and an increase in revenues generated by them according to the Central Statistical Office

One of the ways that can improve the described situation, what is proposed by the re-searchers in the field of improving construction production was and is the application of modern management methods, such as Lean Management in construction.

The key here is the method of selection and implementation of an appropriate method or tool in construction companies and specific processes, especially in the SME sector. If you want to use methods whose theoretical benefits are known and at the same time obtainable, then the question arises regarding the selection of the right method in terms of expectations and the possibility of introducing changes in the given company. It is related to the variable efficiency of methods used in various environments, with other processes and conditions, both internal and external. What’s more, the researchers point out that there is a real need to work on the systematic use of the Lean Management concept in construction (as Lean Construction) clearly indicating that the mere use of the tool is insufficient to fully feel the positive effects of the methodology.

Implementation of industrial parks had become a worldwide trend in recent decades to promote economic growth and reducing social differences among the regions. However, worldwide examples show that many poor decisions were made in the planning stage. As a result, we have a lot of inefficiently working, obsolescence and even abandoned parks. The purpose of this paper is to analyze the theoretical and applicable aspects of the rational plan-ning of efficiency operating industrial parks. The authors presented the comparative analysis of two industrial parks in Tauragė region in term of efficiency.

Comparative analysis of two industrial parks in the same regions proved that demo-graphic situation - labour force and location of the city are important for attracting investors and for the efficient operation of the park. Tauragė industrial park also presents slightly better accessibility results in major airports as well as road transport.

To define the minimum limit of the size, more detailed research needs to be continued. The results proved industrial parks demonstrate better performance (by the number of inves-tors attracted to the park) and have to be developed near major cities to ensure the supply of labour force for developing industries. Making not only industrial park, but also surrounding areas well-developed in terms of quality infrastructure and public services for the investor and its employees is another factor, which adds value to the attraction of the investments to the park and adds benefits to the municipality itself.

The idea of the VINERS project is to perform research on neuro-advertising by applying biometric, physiological, intelligent and affective computer technologies as well as statistical analysis, text and data analytics, recommender and multicriteria analysis methods in order to develop the Video Neuro-advertising (VINERS) Model and System. The VINERS Model is innovative on a global level by the following aspects: 1) compilation and analysis of physio-logical and emotional maps of advertising contents along with neuro-matrices, 2) completion of a neuro-questionnaire and 3) development of the VINERS1 Sub-model for analyzing and assessing the impact of electronic advertising (advertising of contents under development) and the VINERS2 Sub-model for intuitively broadcasting an electronic advertisement (al-ready developed contents of an advertisement). This study demonstrates the Video Neu-ro-advertising Recommender Model by its affective BIM basis.

The research’s aim was to create the Video Neuro-advertising Recommender (VINERS) Model for Affective BIM, a tool that analyse potential buyer emotions, measure how engaging and relevant ads are, and, based on the existing best global practice and the results of analysis, offer tips on ways to make ads more efficient by attuning them to the needs of a target group. This study demonstrates the Video Neuro-advertising Recommender Model by its affective BIM basis. The VINERS model consists of two composite parts. The VINERS1 Sub-model, based on the compiled neuromatrix, help to assess the effectiveness of an advertisement at each stage of its development. It establish the strengths and weaknesses of an advertisement and improve it until its greatest attractiveness to a viewer. The VINERS model be able to compile millions of alternative variants for every element of an advertisement’s contents. Later it able to select the most effective, most suitable advertising variant. Furthermore, the VINERS1 Sub-model ana-lyze various aspects of an advertisement’s audience (demographic, level of education, social, psychological, life style, emotional, cultural, ethnic and others) and evaluate such parameters when making recommendations. The VINERS2 Sub-model generate millions of alternative ad-vertising variants for each viewer of an already developed advertisement. Next, it select a per-sonalized, most suitable advertising variant. The aforementioned methods be integrated as the research is being performed. A worldwide review of scientific research and analysis of patents show that there is no analogical research of integrated neuro-advertising VINERS Model.

INTEGRATION OF LEAN IN CONSTRUCTION PROCESSES

Jolanta Tamošaitienėa, Tomas Startab




The productivity of the construction sector worldwide has fallen over the past 30 years. There is an opinion that application of lean construction concepts and methodologies can help to improve the situation. Lean construction concepts are effective in a strategic approach, striv-ing to reduce waste, expenses and save time on a long-term perspective. Aforementioned contribute in pursuit towards the global environmental and economic goals. Although the lean practice is capable of attaining significant environmental goals, times saving, economic benefits, organizations still experiencing difficulty to integrate these concepts correctly and successfully. Many studies reported that the construction industry has encountered poor implementation and integration of these concepts. Lean construction has eight main tech-niques that help to increase productivity in fulfilling the client’s requirements. This paper provides the fundamental knowledge of Lean construction and shows how to get the most effective results by applying the Last Planner System technique. The case study illustrates the integration of the Last Planner System technique into the construction project.

The low bid is the most common application method in the contractor selection process, considering by only one dominant criterion. However, the lowest price criterion not allows selecting a qualified, responsible, sophisticated, and knowledgeable contractor for cultural heritage projects. Moreover, improper contractor selection may induce claims, litigation, and poor quality work increased costs for project performance or management. Selection of an appropriate contractor is very important for the success and excellent performance accom-plishment of cultural heritage projects. This study presents criteria evaluation for contractor selection in cultural heritage projects. This paper provides reviews of contractor selection and proposed criteria evaluation, and determines the criteria of culture heritage contractor selection. This study applies the multiple criteria approach: integrated determination of ob-jective criteria weights (IDOCRIW) and Bayes approaches.

THE RISK ASSESSMENT MODEL FOR CONSTRUCTION PROJECTS INCLUDING VALUE CREATION AND PROTECTION ASPECTS

Jolanta Tamošaitienėa, Miglė Lapeikytėb




The article focuses on the identification and classification of key risk management criteria that represent the value creation and protection aspects for the construction industry. Now-adays, the assessment of the risk level of a construction project is especially important for the quality of construction projects as well as the growth of enterprises and the sector. To establish the most important criteria for the successful growth of the construction sector including value creation and protection aspects are developed. The article presents the de-veloped and integrated knowledge system for the measurement of a risk level particular to construction projects.

Enterprises implement different projects to achieve goals stipulated in their organiza-tional charter. However, timely completion of such projects is rarely successful despite the reached financial and qualitative goals. One of the most important factors that lead to the incompletion of most projects is the lack of attention to the effects of risks, the aggregated effect of which becomes a major hurdle. In other words, the interactions among risks lead to the aggregated effect, which is greater than the total effects of individual risks.

Risk assessment in an environment involves a systematic and comprehensive meth-odology for quantifying the probability of the occurrence of a particular adverse event and the magnitude of the associated consequence of its outcome. In an environment, risk as-sessment faces different types of uncertainties including aleatoric and epistemic that can be accounted by theories of probability, possibility, game and fuzzy set, respectively. The former type of uncertainty is often referred to as objective or stochastic whereas the latter is often referred to as subjective or state-of-knowledge.

Strategic objectives of an enterprise are accomplished through portfolios of risks. How-ever, the materialization of portfolio risks may affect a portfolio’s success and at the same time the success of the implemented activity. In life, each situation brings together many types of risks. Risk management approaches depend on the context of the risk environment and the business activity, i.e. construction. The new risk assessment model for construction projects is presented including value creation and protection aspects.

Construction is one of the branches of the economy where, for various reasons, it is often impossible to perform work under predetermined and agreed conditions. As a result, there is often a dispute between the contractor and the client. Dispute resolution and successful proj-ect implementation depend on quick and effective conflict resolution. It requires procedures that are reasonably simple, logically accurate, and easy to understand, prioritizing priorities of conflicting parties, and evaluating all critical criteria of parties involved. The resolution of each dispute may have several alternatives. Only in exceptional cases is the choice that best meets all the vital principles and stakeholders’ purposes. Therefore, in assessing such op-tions, the model must take into account the criteria and compromises of members of conflict groups. Also, information about such possibilities cannot be in advance precisely defined. Satisfactory dispute resolution is significant. The authors represent a new model consisting of four multi-criteria assessment methods: ARAS, LINMAP-F and Eckenrode-SWARA rating. The article presents an example of a real decision on the task. For this reason, the authors define the main goals of the dispute groups, form a list of critical criteria for the efficiency of dispute resolution, determine their weights and assessment requirements.

BIM technologies evolve fast in the last decade that brings a big amount of new opportunities for civil engineers. Many companies and universities are investigating new BIM approaches to expend the opportunities for construction and architecture. One of the technologies that got their development is a collaboration of the BIM, GIS and WEB environments that brings many benefits for constructors, architects and managers. To visualize the BIM model the 3D environment need to be developed by the WEB tools and technologies and exists a big amount of projects around the world that has been developed for this purpose. Each project is unique and brings different abilities and tools for model processing and manipulation: some of them are aimed for model visualization purposes, some of them are focusing on manipulations with the BIM model and main functionality of others is the management of the project. The aim of this article is to analyse the most outstanding WEB solutions for BIM model processing from a wide variety of projects and compare them with the WebBIM platform developed and presented in scientific articles. The comparison is done by the op-portunities that projects bring for the civil engineers and architects, implemented functionality with related tools and technologies that are used. Conclusions contain results of the analysis and possible ways of future development in this field. The collaboration of BIM, WEB and GIS technologies is the promising direction of the civil engineering evolution that can be approved by the scientific literature review of the last decade and amount of projects that is rising each year.

Today, state enterprises and municipalities are concerned about the non-effective use of public buildings. The optimization of their quantity, efficient management by ensuring rational use of resources and protecting the societal needs are complex tasks, therefore require the decisions, which based on the application of new knowledge.

The article proposes a new knowledge-based management model, an original set of criteria for assessing the efficiency of public buildings uses. The task of applying this original criteria system for assessing the efficiency of the use of cultural buildings and museums of the exact municipality has been solved. With the help of the new model, municipalities will expand the possibilities for impartial decision-making and evaluate the efficiency of end-use of buildings with respect to social benefit criteria. The results are applicable to public sector organizations, especially for municipalities with particular problems associated with the man-agement of a large number of public assets.

MODEL OF OCCUPATIONAL SAFETY RISKS ASSESSMENT AT CONCRETE CONSTRUCTION WORKS BY

APPLYING TODIM METHOD

Jolanta Tamošaitienėa, Miglė Lapeikytėb




Construction safety solutions are one of the building technology project components in Lithuania. Every construction site and construction conditions, the project environment are unique. Depending on the specifics of the construction work being carried out and the envi-ronmental conditions, the risks to be assessed in each case must be individual. This creates the preconditions for creating a new risk assessment model, which includes risk assessment norms, building object and building process conditions. Expert assessment, TODIM method have been used for the development of the risk assessment model for concrete works. The article presents a practical risk assessment model. The risk of construction of concreting works was assessed in two different construction objects. The results of the research pre-sented in the article are presented according to the riskiest place of work on the construction site of the concreting works, and the line of priorities of the riskiest assessed workplaces.

Buildings have a major impact on the health and well-being of people and to the environ-ment. Old buildings use resources, form waste and are expensive to maintain and operate. Achieving to have zero waste buildings are a practice of building design, construction and operation to increase productivity and decrease energy consumption, to use less resources, to reduce the amount of waste and the negative impact on the environment, and to reduce costs during the life cycle. This research represents building modernization model which creates knowledge-based decision-making method for old public buildings refurbishment seeking to reach the best energy performance during design stage. Using digital systems and simulations this method performs already expected building energy consumption in a quickest and economic way. This model is BIM-based where design and refurbishment are based on pre-built indicators which allows assessing the building energy demand and eco-building parameters.

Applying the building information model is undoubtedly one of the most advanced technol-ogies used in the construction sector, the benefits of which are proven by research. The biggest of the project’s problems, especially delays, are due to harmful practices – con-struction works begin immediately after the contract is signed, without proper analysis of the Client’s needs and the existing construction site situation, with no precise planning of resources, supply and production schedules and even budget. During the pre-construction phase, the solutions must be as thoroughly thought and planned as possible, the resources of the workforce and materials, graphs and project estimates must be provided. Mostly anal-ysis of the pre-construction phase is often refused due to lack of existing situation or design solutions data, complicated calculations of mechanisms, equipment, required storage areas, not enough time to analyze all possible rational solutions.

The relevance of the research: cost-effective and efficient planning of the whole con-struction site – mechanisms, equipment, storage areas, temporary buildings, temporary en-gineering networks, etc. This process is continuous and recurring in every new investment and also it is not identical for every new investment.

After the analysis of management software, it was found that the selected programs do not perform automated construction site designing. Existing programs provide a graphical representation of the construction site, allow for basic collision checks – whether spatial bodies cross in one plane, etc.

In the research presented the principle steps of creation mathematical model for the needs of construction site objects and the methodology and classification of the main site selection.

In order to maximize the optimization and automated modeling of construction site plan-ning, selection of mechanisms, equipment, and other temporary objects, it is necessary to integrate all stages of construction works – earthworks, zero cycle construction, engineering networks and communications, environmental management, etc.

The benefits of research – the result obtained will help:1. Reduce the time and cost of building site planning;2. Determine the need for the necessary machinery, equipment, and temporary objects;3. Accelerate the analysis of alternatives to optimized site planning;4. To choose the most appropriate and rational, optimized version of the site plan in a rea-

soned manner, evaluating the present state and design solutions in an automated way;5. Improve communication and collaboration between project participants.

Reconstruction and restoration of industrial buildings, historical and cultural heritage buildings is an important area worldwide. However, the most advanced digital technologies are rarely used in the area. Using at least a part of building information modeling (BIM) methodology or simply using 3D technologies to generate and further use digital information of historic build-ings is a significant effort to preserve the heritage and retain its most valuable features.

The authors implemented two experimental projects. The first one – old equipment repair factory, located in Vilnius, Lithuania. Information models for both initial and refurbished build-ing are prepared. Parameter object correlation with laser scanning data enabled creation of a virtual 3D model of the historic building. This detailed 3D model contains most of the information about the object and the elements of the object, such as used building materials, operating cost reduction schedules, energy consumption, visualization, drawings, cuts, etc.

As the next example of digital technology application, we would like to present “As-Built” 3D model creation of Sapieha Palace built in Baroque style in 1689–1691 in Vilnius, Lith-uania. Research methods and tools – initial data collection by historical drawing analysis, manual measurement and photogrammetry methods. For initial data preparation were used the DJI Mavic Pro drone with a DJI FC220 digital camera with 3-axis stabilization system and a navigation system for positioning. For photo processing, Agisoft PhotoScan software was applied. After this, a cloud of points was combined with a sketch in the Revit software, and on the basis of this a 3D model was created.

Benefits of building information modeling are difficult to measure because different par-ticipants of a construction project expect different results from applying BIM. Some of bene-fits of BIM uses, such as preliminary/detailed visualization, review of structural solutions and alike can be used by all project participants. However, there are other special benefits of BIM uses, which are specific to stakeholders, for example, analysis of engineering system pa-rameters. The main advantage of digital measurements is the ability to accurately measure hard-to-reach and sometimes invisible places, to detail large-scale or complex surfaces and objects with many details. This helps to solve complex cases where architectural manual measurements are not feasible, difficult to implement, or financially unreasonable. Using digital data can accurately determine the extent of defects and planned works, thus not only identifying and solving problems of heritage object, but also saving the customer’s funds.

Keywords: historical and cultural heritage buildings, BIM
