Research on the Requirement Analysis and Management Method of Aircraft PHM System

Abstract

Abstract Recent years, the forward design based on requirements has become the mainstream mode of aircraft and its component systems development. Requirements analysis and management not only runs through the whole process of system development and validation activities, but also plays an important role in these activities. However, there are some practical problems in the requirement analysis and management of prognostics and health management (PHM) system of aircraft, such as lack of method and process guidance, incomplete stakeholder analysis, and nonstandard requirement description. Therefore, based on the theory of system engineering, this paper puts forward the basic methods and suggestions of PHM system stakeholder analysis, formulates the technical process and key points of PHM system requirement analysis in demonstration and scheme stage, and clarifies the basic principles of PHM system requirement specification. And the related research of this paper aims to improve the quality and efficiency of requirement analysis and management of aircraft PHM system, and to lay the foundation for the development of system architecture and function as well.
