Discussion on Application of Model-Based Systems Engineering Method to Human Spaceflight Mission

Abstract

AbstractConsidering the fact that design data exist in different documents dispersedly and are difficult to keep consistent and hard to trace, the concept of MBSE (model—based systems engineering) method is introduced. Firstly MBSE method can graphically support system requirements, design, analysis, verification and validation activities in whole life cycle. Then a general process of MBSE method is summarized, creating a requirement model to guide the construction of functional model and physical architecture model etc. Based on a set of predefined rule the relations among models are set up, by which relevance among design elements and information can be analyzed and searched out. In the end, an example is presented to show how to apply MBSE method to design manned spacecraft docking missions. It is concluded that MBSE method can improve the communication, increase work efficiency, and reduce design risk. The work is a good reference for further application.KeywordsSystems engineeringHuman spaceflightMBSERequirement modelFunctional modelPgysical architecture model
