Towards a better interaction between design and dependability analysis: FMEA derived from UML/SysML models

Résumé

It is commonly admitted that one of the crux, during the design process of new complex systems, is the efficient communication between the experts. The OMG developed UML to tackle this problem in software design. For several years, many researchers have worked on adapting and reusing UML for whole kind of systems. These efforts led to the creation of SysML, a new modeling language for specifying, analyzing, designing and verifying complex multi-disciplinary systems. In this paper, we present how those modeling languages can be integrated to combine reliability study with the design process in order to compose a conception process close to dependability priorities. We have set up a method to conduct reliability studies without perturbing the classic procedures of designers. Our objectives were on the one hand to facilitate communication between functional and dysfunctional analyzers and to simplify the execution of reliability studies on the other hand. In this article, we raise the utility of FMEA for a non-intrusive modeling of dys-functional aspects. We thus give our solution for an automatic synthesis of FMEA from UML/SysML models, which only describe the nominal behavior. We insist on the keystone of this automatic synthesis, namely the use and management of a database constructed from the information of the return on experience. The purpose of this article is thus to describe a new approach to enhance the realization of dependability studies by auto-mating steps and using easily understandable models.
