Weapons equipment portfolios selection based on equipment system contribution rates

Equipment selection is an essential work in the research and development planning of equipment. The scientific and rational development of weapons equipment portfolios is of considerable significance to the optimization of equipment architecture design, the adequate resources allocation, and the joint combat performance. From the system view, this paper proposes a method of weapons equipment portfolios selection (WEPS) based on the contribution rate of weapon systems, providing a new idea for weapon equipment portfolio selection. Firstly, we analyze the WEPS problem and the concept of the contribution rate under the systems background. Secondly, we propose a combat network modeling method for weapon equipment systems based on the function chain. Thirdly, we propose a WEPS method based on the contribution rate, fully considering the correlation relationships between potential weapons and the old weapon systems by the combat network model, under the limitation of capability demands and budget resources, with the objective to maximally increasing the combat ability of weapon systems. Finally, we make a case study with a specific WEPS problem where the whole calculation processes and results are analyzed and exhibited to verify the feasibility and effectiveness of the proposed method model.
