摘要

Self-organized service chain formed by service agent can't complete the scheduled collaborative target because of exceptions of service provider. This paper presents a service chain evolution model based on collaborative state. In the model, service collaborative relationship is modeled as a contract set, whose performance results are regarded as the result of service coordination state. And then the monitoring and evolution policies of collaborative process are established based on collaborative state. On this basis, a collaborative scenario-driven adaptive and self-evolutionary mechanism for service chain is established. Based on planning policies, different evolution plans are formulated to obtain a better flexibility of service chain.
