集不变条件下的服务组合演化行为研究

从业务逻辑的一般性变更与演化需求出发，研究了服务组合中服务集合不变条件下的服务演化行为，提出了组合服务的合理演化行为集SEBS(Sound Evolution Behavior Set)，定义了一组服务工作流程结构调整的基本演化操作，证明了演化行为集SEI3S能够保持演化后组合服务的合理性，从而能够保证在发生基于业务流程变更的服务组合演化操作后，其内部流程逻辑的合理性不变，并通过服务组合演化示例进行了实际应用说明。

Study on Evolution Behavior of Service Combination under Unchanged Set

Started from the business logic of common update and evolution demand,this paper studied the evolution behavior of service combination under the condition that service set in service combination can't change. I3y proposing the evolution behavior set SEI3S in service combination, this paper defined basic evolution operation of service work flow architecture adjustment and proved that SEI3S can maintain the rationality of service combination after evolution. Thus,the rationality of inner flow logistic can' t change during the operation of service combination evolution. A case study shows that it can be put into practice.
