Abstract:
Parametric analysis is an essential tool in optimizing the performance of any system; it is, in particular, used to fine-tune key parameters in a system design process. In this paper, using a vehicle cruise control system as a non-trivial case study, we introduce a new approach for the performance parametric analysis of complex systems using SysML models and a parametric constraint solver. System requirements are taken into account to verify automatically whether the design solutions satisfy these requirements. This suggests that in order to reduce time and resources, it is possible to perform initial performance analysis in a modeling tool, just after the system functional and architectural analyses. Of course, once an approximate operating point has been determined using this approach, experiments in specialized simulation tools can be used to confirm and further refine the parameters of a system.
