Abstract:

Aiming at the complex structure of the equipment system-of-systems and other characteristics, an equipment system structure contribution rate evaluation model based on the design structure matrix (DSM) and information entropy is constructed. First, based on the idea of "all-round, dynamic, and confrontational", the dynamic-static DSM evaluation model for the assessment of the contribution rate of the equipment system is established; second, the combat process is decomposed with the smallest single capability as the granularity, and the capability structure of the equipment system is analysed according to the meta activity sequence. After the networked modeling is carried out, the information entropy method is used to calculate the sensitivity of equipment capabilities. Taking a certain aviation combat equipment system as an example, the feasibility and rationality of this method are verified.

Key words: design structure matrix (DSM), capability, meta activity, self-information
