With the emergence of network centralized simulation application mode in the future, more and more simulation models need to be shared and reused. Using the idea of conventionalized software, this paper proposes the method of integration based on simulation component model, introduces the concept of simulation model components, analyzes the functional architecture of the integration framework of simulation component model, describes the integration specification of simulation component model and the development interface of simulation component model. Finally, the feasibility of component-based simulation model integration is verified through a combined example of radar simulation model.
