System-of-systems (SoS) contribution ratio evaluation is an important measure to promote the development and application of equipment system-of-systematization. At present, the research of SoS contribution ratio (SoSCR) mainly focuses on the stage of equipment project demonstration. There are some problems such as difficulty to find the combat SoS comprising the equipment system from bottom up, atypical and inaccurate SoSs, so it is urgent to strengthen the research of SoSCR from top down in the stage of program planning. Based on the thought of equipment life cycle management dominated by SoSCR, this paper puts forward a five-step evaluation method, including combat concept traction, capability demand leading, value orientation accounting, mission means matching, and capability contribution evaluation. The SoSCR of the project is evaluated according to the satisfaction degree of the equipment planning project to the SoS capability gap, and an SoSCR allocation model is constructed. In this paper, the evaluation of SoSCR is pushed forward to the program planning stage, which can strengthen the top-level design and overall guidance of equipment life cycle management, and overcome shortcomings of current research on decentralized and fragmented SOSCR.
