Cost risk assessment method for system construction based on the trade-off between cost and capability

The construction of SoS is a key and difficult content in the development plan of military construction. In response to the problem of continuous cost risk generation in the process of SoS construction cost investment, focusing on the mechanism and growth path of combat effectiveness generation, a SoS construction cost risk assessment method oriented towards “cost capability” balance is proposed. Firstly, define and analyze the concept of cost risk in SoS construction; Secondly, construct an evaluation model for the dependency and constraint relationships between factors such as SoS construction costs, capabilities, and risks; Finally, taking the construction of a SoS under task guidance as an example for case verification, the experimental results show that the proposed method can achieve cost risk assessment under the trade-off of "cost capability", and the selected MOPSO algorithm has strong robustness.
