基于事件-状态-过程规则的跨组织工作流协同方法

Collaboration method for inter-organizational workflows based on ESP rules

目前跨组织工作流协同建模时,各个组织内业务模型的独立性和隐私性较差,"全局"协同模型的柔性不好,且缺乏描述协作活动之间细粒度操作语义。依据协调理论的思想,提出了一种基于事件-状态-过程规则的跨组织工作流协同方法,其核心是采用事件-状态-过程规则形式表达的协同工作流来控制和协调多个组织内业务流程的运行。该方法中的业务工作流程仅曝露需要交互的活动,从而保证了其独立性和隐私性。同时,协同工作流由一系列具有细粒度操作语义的协同活动组成,并且基于事件-状态-过程规则的形式,可进行灵活的定义和删除,具有较好的柔性。

There were problems existing in current collaborative modeling and analysis of inter-organizational work- flows, such as lack of independence and privacy for local workflow models, low flexibility for collaboration models and lack of method to describe small granular operation semantics for interactions. Based on the coordination theory, a collaboration method for inter-organizational workflows based on ESP rules was proposed, which used the collabo- ration workflows in form of Event-State-Process （ESP） rules to control and manage workflow operations. Only ac- tivities needed interactions were exposed in this method so as to keep the independence and privacy of workflows. Furthermore, collaborative workflows were composed of collaborative activities with small granular operation se- mantics which could be defined and deleted flexibly.
