Abstract: This paper analyzes the method of service-oriented analysis and design (SOAD). Combining the service definition hierarchy with hybrid modeling approach, a new combined application way is suggested. The modeling steps of meet-in-the-middle are employed to build the system model. In the process of designing and developing the ASP network service system, the feasibility of the method is validated in typical application.
