Gartner Hype Cycle

Model-Based SYSTEMS ENGINEERING (MBSE)Models, not documents, as the primary means of information exchange

Modeling the structure, behavior and performance (including response to errors and malfunctions) of system elements individually and in integrated combinations to simulate, analyze and optimize functional allocation within the system architecture and to verify the resultant design functionality, performance, safety, failure propagation, testability and maintainability properties

ISO 10303-209 (STEP AP209) • Strong need for interoperability between

design and analysis environments due to the ever growing size needs to be exchanged and managed under configuration control

• Simulation analyses also tends to support more and more certification processes, leading to increased traceability requirements

• Standard for sharing, exchange and long term archiving of information between the iterative design and analysis stages of the product life cycle

• ISO STEP activity with the U.S. being overseen by PDES Inc.

• Slow but promising adoption among software vendors

• Initiated by Lockheed-Martin and now led by Boeing and Airbus

• Very active and strongly supported by top Aerospace and Defense companies

8More information on STEP AP209 can be found at http://www.ap209.org/

ISO 10303-233 (STEP AP233)• Defines a vendor-neutral, structured format for exchanging

and sharing systems engineering data

• Data can be exchanged as a standard file (plain text or XML), or shared using technologies such as web services

• The scope of AP233 is quite broad, covering everything from requirements, through functional modelling, to product structure (e.g. bill of materials)

• The standard is founded on models for configuration control, properties, security, risk, verification & validation, interfacing and generic models for creating hierarchies of systems, parts, functions etc.

• AP233 covers the whole systems engineering lifecycle and provides the necessary links into domains such as engineering analysis, detailed design, manufacture and operation

• Supported by INCOSE and is being developed in cooperation with the SysML team

• More information on AP233 can be found at http://ap233.eurostep.com

SysML• The SysML initiative originated in a January 2001 decision by INCOSE (International Council on Systems Engineering) Model

Driven Systems Design workgroup to customize the UML for systems engineering applications• The Systems Modeling Language (SysML) is general purpose visual modeling language for Systems Engineering applications

• SysML supports the specification, analysis, design, verification and validation of a broad range of systems and systems-of-systems. These systems may include hardware, software, information, processes, personnel, and facilities

• SysML is defined as a dialect of the Unified Modeling Language (UML) standard

• SysML offers systems engineers several noteworthy improvements over UML, which tends to be software-centric These improvements include the following:

» SysML's semantics are more flexible and expressive» SysML reduces UML's software-centric restrictions» SysML is able to model a wide range of systems, which may include hardware, software, information, processes,

personnel, and facilities.

• SysML is an enabling technology for Model-Based Systems Engineering (MBSE)

• More information on SysML can be found at http://sysml.org/

INCOSE (International Council on Systems Engineering)

NAFEMS

An independent not-for-profit body with sole aim of promoting the effective use of engineering simulation methods.

• Founded in 1990, it is the international association for the engineering analysis community

• Information source for the latest CAE technology developments

• Source of best practice guides for the use of analysis technology

Systems Modeling & Simulation Working Group (SMSWG) Mission

Objective: » NAFEMS and INCOSE agreed to a mutually beneficial strategy to develop a collaborative

relationship that would benefit both the organizations and their members.

• To develop a vendor-neutral, end-user driven consortium that not only promotes the advancement of the technology and practices associated with integration of engineering analysis and systems engineering, but also acts as the advisory body to drive strategic direction for technology development and standards in the space of complex engineering.

• This group will support activities that bridge engineering analysis and systems engineering to provide digital solutions to represent real life experiences; and optimize the integration of systems engineering and simulation solutions for both OEM and supplier.

• This includes education, communication, promotion of standards, and development of requirements that will have general benefits to the simulation and analysis community with the identification of benchmarks and major strategic issues (grand challenges).

Tie Yourself to Standards, Not Tools!1. It will be cheaper2. It will keep software vendors on their toes to compete

on tool capability, not quality of lock-in3. It returns ownership of the know-how in the models

from the tool vendor to the end user4. It will move from process improvement evolution to

process improvement revolution

Key Take-Away

Summary• Enforce standards!• If you are not already part of a standards

promoting organization, join one (or more)• All data, access through different software with

looser coupling is much better than partial data that is fully integrated

• Industrial users must promote standards and vendor cooperation to achieve a comprehensive interoperable MBSE technology platform
