With the wide application of simulation system in the field of military test and training, a variety of simulation application platforms have been developed. The simulation models developed based on these simulation platforms are difficult to reuse between different simulation application platforms due to their different technical architectures and operating mechanisms. In view of the problems faced by the reuse of simulation models, this paper summarizes and analyzes the current simulation model reuse methods, proposes a method to realize the reuse of simulation models by using object model modeling and service-oriented encapsulation technology, and based on this method, a service-oriented encapsulation framework for simulation models is encoded, and finally realizes the reuse on the VMS simulation application platform through the service-based packaging of simulation models such as tanks and infantry vehicles in the SSG simulation application platform, and the verification results show that the proposed method can support the flexible reuse of simulation models.
