Flexibility Management in Distributed Workflow System
分布式工作流系统的柔性管理

The research about the flexibility is one of hot topics in fields of workflow system currently.In this paper we discuss the flexibility management in distributed workflow system.The workflow interface-workflow definition substitutes the traditional workflow definition in current workflow model definition,and the workflow definition is classified into pre-defined operation packets and extended-defined operation packets,so the dynamic function self-adaptation is realized.Executing engines can (register) and logout dynamically in executing,and the concerted engine and the route rules collection are appended,so the alterable route self-adaptation performs successfully.
