Service-oriented Simulation Driven By Business Process

With the development of computer simulation technology,it is more and more widely applied.However,due to low efficiency,poor flexibility,the lack of scalability and other issues,computer simulation technology faces enormous challenges.Service oriented technology has pointed out a new direction for the development of computer simulation technology.In view of the urgent need for business process simulation based on service oriented large-scale system,this paper puts forward service oriented simulation architecture of business process-driven.Based on this architecture,service oriented simulation driven by business process is proposed and studied.Firstly,this paper studies the encapsulation technology of simulation service for the service layer in the architecture.In this part,the simulation service is redefined and described in SSDL;the encapsulation method of the simulation service is proposed by AXIS2 engine and the WSDL document is extended to provide the service foundation for service oriented simulation driven by business process.Secondly,a simulation service composition mechanism is proposed for service oriented simulation driven of business process.In this part,a simulation service composition algorithm based on shortest path is proposed.The experiment proves that the algorithm improves the accuracy of service selection.In addition,a BPEL document generation method is proposed to implement the business process of simulation service.Finally,the development environment based on service oriented simulation driven by business process is designed and implemented and it can meet the requirements of military simulation service.Then,an example of the air defense combat mission is used to demonstrate the application of the simulation service,and it verifies the correctness and practicability of the proposed method.This paper uses the service oriented simulation driven by business process,applies the simulation technology to the entire service process life cycle for each scene and improves the accuracy of service selection and efficiency of the service composition.
