A Discussion on Detailing Processes for Improving the Dependability of Aerospace and Automotive Systems 2019-36-0299

Complex and/ or highly integrated systems such as satellites, airplanes, air traffic controllers, cars, etc., require Dependability (Reliability, Maintainability, Availability, Safety, Security, etc.) assessments throughout their life cycle, especially in their development, where the time and cost to make changes are smaller. Such systems must achieve high levels of Dependability through a variety of approaches and processes. Among these, the processes of analysis and decision making from the conception phase to the final phase of the detailed project stand out, because in these phases the most important decisions are taken. Thus, the purpose of this article is to present a discussion on detailing processes for improving the Dependability of aerospace and automotive systems. For this, it will present: 1) detailing process of a Dependability engineering; and 2) detailing process of a Dependability assurance, in order to establish processes that define/ highlight/ clarify activities pertaining to each area/ discipline (Engineering and Assurance). These details were obtained from information collected from specialists in the area, experiences of the related areas of INPE and of companies contracted by INPE. It is expected that the adoption of such processes and detailing will produce: 1) improvements in the Dependability assessments and consequently; 2) shortened deadlines, costs and efforts devoted to the needed developments; 3) same as unnecessary rework.
