Semantic Interoperability in Interorganizational Workflows

چکیده

Most workkow model and systems only support the separate and independent execution of business processes. However, processes often need to interact with each other, by synchronizing the execution of their activities and by exchanging process relevant data; in particular, activities which are performed in the context of a process may need to innuence activities of a diierent process in a way that, laying \between" the two processes, is quite diicult to design, formalize, and understand. These problems particularly occur when processes are executed in diierent organizations, and are managed by diierent systems. In this paper we propose a workkow model that allows for a exible semantic workkow interoperability, enabling the cooperation among interorganizational workkows; we extend traditional workkow conceptual models by allowing workkows to publish and subscribe to events, and by enabling the deenition of nodes in the process execution where events should be sent or received, along with event parameters that provide for data exchange between workkows. We then present how events can be dispatched in a multi-organizational context, and nally we discuss some properties related to the analysis of interacting workkows.

Verification of Itineraries for Mobile Agent Enabled Interorganizational Workflow

We apply mobile agents to synchronize workflows of different organizations resulting in an interorganizational workflow. This paper models agent enabled interorganizational workflows using Interorganizational Workflow Nets. This model provides a means to verify the correctness (and, so the viability) of the itineraries of agents used in enacting interorganizational workflows. We also outline an...

Temporal Consistency of View Based Interorganizational Workflows

Interorganizational workflows are a major step in automating B2B electronic commerce and to support collaborations of organizations on the technical level. Process views are an important conceptual modelling approach for interorganizational workflows as they allow interaction and communication while internal and private parts of the process can be hidden. However, it essential to guarantee that...

WF-Net Based Modeling and Soundness Verification of Interworkflows

This paper deals with WF-net based modeling and verification of interorganizational workflows (interworkflows for short) based on the protocol of WfMC. In the protocol, there are three patterns of interoperability: Chained, Nested, and Parallel synchronized; and an interworkflow is constructed by using those interoperability patterns. We first give a WF-net based modeling method. In this modeli...
