Facilitating R&M in spaceflight systems with MBSE

Abstract

An innovative modeling technique was developed to merge Reliability & Maintenance (R&M) activities with Model Based System Engineering processes. Associated tools were developed to automatically extract R&M products (FMECA and Fault Trees) from the model. The modeling technique and tools were successfully applied to a NASA/JSC project. The method enables the R&M perspective to be taken into account as key design decisions are being made during the design process.
