This article follows a line of papers focused on defining a method to improve the realization of reliability analysis during the System Engineering process. As MBSE becomes a fundamental concept for specifying and designing systems, our method takes full advantages of this approach and try to provide tools to ease the specification stage and the integration of RAMS early in the conception process. Our method called MeDISIS is related to the use of SysML to support MBSE and RAMS activities Currently, MeDISIS is used within an industrial project to design a hypersonic aircraft which is a relevant complex and critical system. During this project, MeDISIS has been adapted to take into account technologies devoted to embedded systems. Furthermore, MeDISIS had to comply with the tools, used by our industrial partners during the design stage. In this work, we present the new architecture of MeDISIS, and the process added recently.
