Abstract: The operation loop method is improved and introduced into the solution to the evaluation problem of the effectiveness and equipment contribution rate of high confrontation armament system-of-systems in air combat and other fields. First, an operation loop network model considering node failure is constructed to describe the armament system-of-systems containing comprehensive equipment, and a method for calculating edge and node weights based on fuzzy comprehension evaluation is presented. Secondly, combined with the idea of network reliability, a Monte Carlo method based on depth-first search is provided to calculate the efficiency of armament system-of-systems, and a general contribution rate calculation method for multiple evaluation objects with the participation of comprehensive equipment is given. Finally, a sea interception operation system of systems is taken as a case study to verify the feasibility and effectiveness of the proposed methods.

Key words: operation system-of-systems, evaluation of contribution rate, operation loop, fuzzy comprehension evaluation method, network reliability
