6. Fourth IFSA World Congress

The International Fuzzy Systems Association is pleased to announce the fourth IFSA World Congress, which is to be held on the campus of the Free University of Brussels, Brussels, Belgium, 7-12 July 1991.

As was the case for the previous conferences, the objective is to encourage communication between researchers throughout the world, whose research uses or develops in some significant way theory and/or applications of fuzzy sets. Researchers are invited to submit manuscripts to the program committee for consideration.

The organizing and program committee co-chairmen are:

Prof, Dr. R. LOWEN Dienst Wiskundige Analyse Universiteit Antwerpen, RUCA Groenenborgerlaan 171 B-2020 Antwerpen, Belgium

Prof. Dr. M. ROUBENS Institut de Math6matique Universit6 de Liege 15, avenue des Tilleuls B-4000 Liege, Belgium

Extended abstracts or manuscripts may be submitted to either one of the program committee chairmen as of now, or to the day chairs to be announced in the second call for papers which will be communicated in June 1990. Final submission date is September 1, 1990. Notification of acception and detailed instructions for the preparation of the extended camera-ready 4 page abstracts will fol low before October 1, 1990. The extended abstracts should be submitted by December 1, 1990, for inclusion in the proceedings of the conference.

The themes of the conference include but are not limited to those of the fol lowing four main areas. It is important that submission should be clearly classified as to the area most closely related to the contents of the manuscript.

(1) Artificial intelligence: Approximate Reasoning, Knowledge Acquisition, Knowledge Representation, Expert Systems, Natural Languages, Neural Networks, Thinking Models.

(2) Computer Science: Automata & Grammars, Information Retrieval, Databases, Manage- ment Sciences, Operations Research, Decision Making, Socio-Economic Systems, Fuzzy Modelling, Relational Equations.

(3) Engineering: Robotics & Control, Process Automation, Monitoring & Diagnosis, Compu- ter Vision, Pattern Recognition, Production Research, Hardware Devices, Decision Systems.

(4) Mathematics: Analysis, Topology, Measure Theory, Probability & Statistics, Algebra, Category Theory, Logic, Approximation Theory.

The organizers look forward to welcoming you in Brussels in July 1990.
