Research on Contribution Rate Evaluation of Armament System-of-Systems Based on Interval-Value Function *

Understanding the impact of individual armament’s contribution on armament system-of-systems (ASoS) is imperative for system designers to better measure combat effect and develop more competitive systems in the development stage. However, existing approaches do not consider the impact of the warfare scenario on the assessment when facing multiple combat missions. In this paper, we proposed a method based on interval-valued function to evaluate the contribution rate of ASoS in different combat scenarios. Firstly, a capability index system based on combat missions was established, and system-of-systems evaluation scenarios were generated. Then, the interval-valued function was introduced into a capability demand satisfaction degree model. Finally, the contribution rate of ASoS was evaluated and revised based on TOPSIS and grey entropy model. Afterward, an air-combat scenario was utilized as a case study to exemplify the implementation of the proposed approach and subsequently demonstrated its validity. The results show that our approach can effectively evaluate the contribution rate of ASoS in different scenarios, which can help us better identify the priority and provide theoretical support for the development and adoption of armament.
