ASP Service Lifecycle Management Technologies for Networked Manufacturing System

In order to effectively manage services in ASP service mode to provide better service quality, this paper presents the concept of service lifecycle management.We formally define ASP service as an eighttuple format,and set up a lifecycle state model,in which the lifecycle of ASP service is divided into seven states,including creation,integration,running,evaluation,optimization,freezing and elimination.Then, we explore the implementation schemes for such key units as service integration specification,initialization process of service startup,service running monitoring and service level evaluation.Finally,the application of these technologies is reported in a practical networked manufacturing system in Shaoxing textile area.
