Abstract

The invention relates to a DSM-based satellite coupling design flow structured analysis and retrieval method and belongs to the field of design of spacecrafts. The method includes the first step of sorting and summarizing the general flow of designing remote sensing satellites or other types of spacecrafts on the basis of a traditional process expression mode, the second step of conducting mapping to generate a DSM matrix, conducting statistics on DSM items and conducting structured quantitative analysis item by item to obtain a perfect parameter correlation list, and the third step of utilizing the spreadsheet-based middleware technology to achieve storage of a spreadsheet in a database, and retrieving the coupling design process of the satellites according to the storage information about DSM correlation subitems in the database. According to the DSM-based satellite coupling design flow structured analysis and retrieval method, on the basis of the existing design process of the spacecrafts, the design process is mapped to generate a DSM, the DSM is stored into the database for maintenance, the Excel spreadsheet is used as a front-end interface, and consequently a foundation is laid for follow-up optimization.

Description

technical field [0001] The invention relates to a DSM-based satellite coupling design process structural analysis and inversion method, which belongs to the field of spacecraft design. Background technique [0002] Design Structure Matrix (DSM) technology is suitable for modeling the coupling relationship of a complex system, and has been widely and deeply applied in the European and American aerospace industries. DSM is developed from a directed graph, and describes a certain type of design factors in the form of a mathematical matrix, such as design parameters, design activities, etc., and complex relationships such as interdependence and constraints. During the design evolution process of spacecraft products, the parameter configuration is constantly updated, tends to be mature and stable in a spiral iterative mode, and finally reaches the predetermined design goal. The design structure matrix can reflect the potential problems in product design and its process more comp...
