Abstract: Cross-organizational collaboration encompasses two main factors: the coordination of information flows among organizations and the autonomy of each participant. This paper proposes an approach based on public view and object Petri net, which is inspired by the similarity between cross-organizational workflow modeling and object Petri net. The public view of each organization is the external projection of actions that are relevant for partners, which hides the details of the internal process. This paper constructs the information flow net of organizational coordination by the composition of each participant’s public view, and establishes the synchronization relationship between the organization’s internal processes and communication structure by the interaction set of object Petri net. A modeling instance demonstrates the effectiveness of the approach.

Key words: workflow modeling, cross-organizational process, public view, object Petri net

摘要： 组织间协同的信息流以及每个参与组织的自治性是跨组织协同的两个要素。结合跨组织工作流建模与对象网之间的相似性，提出了一种基于公共视图和对象Petri网的跨组织工作流建模方法。组织的公共视图隐藏了内部流程细节，是原流程中仅与合作伙伴相关的活动在外部的投影。通过组合各参与组织的公共视图得到了跨组织协同的信息流网结构，利用对象网的交互集建立了组织内部流程与通信结构的同步关系。通过一个建模实例阐述了该方法的有效性。
