Abstract:

The evaluation of contribution rate is very important for the construction of equipment system-of-systems (SoS). It is difficult to evaluate the contribution rate of SoS due to the emergence of SoS when studying the influence of different equipment on equipment SoS. Therefore, based on the analysis of the SoS architecture and effectiveness index, the emergence of equipment SoS effectiveness is analyzed, and the system dynamics model is used for the simulation evaluation of the equipment system effectiveness, and the evaluation method of the equipment contribution rate is proposed. Finally, a case study of contribution rate evaluation for missile equipment SoS is conducted to verify the proposed method. This paper proposes a simulation analysis method which combines qualitative and quantitative analysis of equipment system contribution rate based on system dynamics, and thus can provide reference for equipment system contribution rate evaluation.

Key words: emergence, system dynamics, contribution rate, equipment system-of-systems (SoS)
