The expected benefits of model-based systems engineering (MBSE) include assistance to the system designer in finding the set of optimal architectures and making trade-off analysis. Design objectives such as cost, performance and reliability are often conflicting. The SysML-based methods OOSEM and the ARCADIA method focus on the design and analysis of one alternative of the system. They freeze the...
Model-Based Systems Engineering (MBSE) with the SysML language allows the designer to include requirement capture and design representation in a single model. This paper proposes a methodology to obtain the best design alternative, from a SysML design, by using multi-objective optimization techniques. A SysML model is extended with stereotypes, objective functions, variability and constraints. Then...
Finding the set of optimal architectures is an important challenge for the designer who uses the Model-Based System Engineering with SysML. The paper discusses the application of techniques to solve a Constraint Satisfaction Multi-criteria Optimization Problem (CSMOP) obtained from a SysML model. In this paper, we present our methodology and propose several stereotypes for model variability, including...
