英文摘要：

This paper studied the simulation process for supporting the C4 ISR system requirements validation. To solve the problems of requirements simillation and reuse the issues in different phases and domains, we used simulation concept model of the C4ISR system to describe different aspects of the characteristics of requirements simulation abstractly, including system functions, operation activities, system states and so on. Based on that, we built the simulationoriented C4ISR system requirements component model, and analyzed the feasibility of the component model with case study.
