Study of ASP service lifecycle management technologies for networked manufacturing system

Nowadays, networked manufacturing system based on ASP (application service provider) has become one of the hotspots of research and application. How to manage large amount of ASP services, and how to provide better service quality, has become very important. The paper mainly studies the ASP service management technologies. We present the concept of service lifecycle management (SLM), defines ASP service, and set up a state model for service lifecycle. Then, we give several key technologies´ solutions for implementation of service management. Finally the application of these technologies in a real networked manufacturing system is introduced.
