Abstract: Aiming at the problems of difficult model representation, poor coordination matching and insufficient exploration trade-off between the overall combat capability and the single equipment capability improvement in the long-term evolution process of complex equipment system-of-systems (CESoSs), a design space exploration method of CESoSs for long-term evolution overall performance improvement is proposed. The main challenge of CESoSs in the long-term evolution process are described. On this basis, the capacity change, SoSs resilience and equipment cost before and after the new equipment is integrated into the existing SoSs are taken as the objective functions. The use of the existing equipment, the indicators of the new equipment and the synergy between the two are taken as the design variables to construct a coupling optimization model considering the single equipment performance and the overall capacity. In view of the uniqueness of design variables and the high-dimensionality of the solution space, the multi-granular coding NSGA-III is used to explore and solve the design space of CESoSs. The case verification results show that this method effectively realizes the optimization solution of CESoSs design scheme under long-term evolution, fully excavates the overall potential of SoSs combat capability, and provides a solid theoretical framework for the future development of equipment SoSs design.
