Function-Oriented Risk Model for Engineering System

Abstract:

Risk analysis is important to increase the reliability of engineering system. And an excellent model is the foundation. Traditional models are event-oriented so that it can’t describe the totality of the system. This paper introduces a function-oriented modeling approach-Goal Tree Success Tree and Master Logic Diagram. It provides a powerful functional/structural description and modeling method. It can represent the goals, the functions, the components and their interactions of the engineering system. So, it is a systemic modeling method for the risk analysis of engineering system. A case study of the servo mechanism of the launch vehicle shows that this approach can identify the key risk factors and the hidden risk factors. And it can trace the failure influence. It provides a systemic approach to risk analysis for researchers
