MBSE-driven Exploratory System Architecture Analysis Framework for the Engineering Test Satellite-9 Project

This paper introduces an application of Model-Based Systems Engineering (MBSE) for the risk management of JAXA's Engineering Test Satellite-9 project. The comprehensive analysis of failure modes of a complex system is a challenging issue for project systems engineers due to the complex interaction between components developed by different providers. Current MBSE practices focus on the formalized description of the system architecture to manage complexity. The main idea of this paper is MBSE-driven systems architecture analysis enabled by the fusion of MBSE-driven architecture description and data analytics. We propose an exploratory system architecture analysis framework that combine SysML-based MBSE process with R-based data analytics. We provide results of the failure mode analysis for the Hall Thruster System newly developed for the next generation all-electric satellite system. We also demonstrated the capability of workflow orchestration for generating the project engineering dashboard combining the OpenCAESAR framework.
