Abstract: For the complex modeling problem caused by the complex communication,interaction and collaboration between multiple organizations in the collaborative business process,a view-basedapproachforcollaborative business processes was proposed.The private view was defined,and the control flow of private view was maped into a tree structure.Based on the tree structure,the migration technology for each of the four relational nodes was proposed.On this basis,the private view was migrated to the public view,and then a modeling method for constructing a collaborative business process was proposed,by which the collaborative business process constructed was theoretically proved to be correct.By modeling actual case and comparing them with existing typical methods,the analysis results showed that the proposed method could improve the privacy protection under the premise that the correctness of the collaborative business process before and after the migration was consistent and the modeling efficiency was not affected.

摘要： 针对协同业务过程中因涉及多个组织间复杂的通信、交互及协作关系而导致的复杂建模问题,基于视图提出一种协同业务过程建模方法。首先定义私有视图,然后将私有视图控制流映射为树结构,最后基于树结构提出4种关系节点各自的迁移技术,以此为基础将私有视图迁移为公共视图,进而提出构建协同业务过程的建模方法,并从理论上证明该方法所构建协同业务过程的正确性。通过实例建模与现有方法进行对比分析表明,所提方法可在确保迁移前后协同业务过程正确性一致和不影响建模效率的前提下,提高隐私性保护力度。
