【摘要】 采用协议对基于Web的业务流程建模是当前研究的一个新方向.业务协议是对参与业务过程的业务步骤的描述.本文将多个参与者参与的业务步骤抽象为参与者之间的交互,采用基于交互的协议对业务流程建模,提出了一个业务协议组合代数,构造了一组协议组合算子,并证明了该代数的一些相关性质;本文还对协议的相似性进行了分析,为替换协议的选择奠定了基础.文章还通过一个流程组合实例说明了基于协议组合代数的业务流程整合过程.更多还原

【Abstract】 It is a new direction that modeling Web-based business processes with protocols.Business protocols are description of action steps of processes in which several participants are involved.This paper Abstracts business steps as conversations between participants and models business processes using protocols based on conversations.A business protocol composition algebra is introduced and a set of composition operators are constructed.Some properties of the algebra are proved.There also analyzed in the paper the similarities of protocols which lays a foundation for replacement of protocols.The paper also illustrates the integration procedure of business processes based on protocol composition algebra through a process composition instance更多还原
