| Zusammenfassung | With the advent of collaborative business processes that may include different parties, the interaction means between those processes steadily gains more importance. Despite this issue the modeling of message-based interactions is very complex and error-prone due to the inherent properties of asynchronous communication. In order to alleviate this problem several predefined interaction protocols such as contract-net or different auction types have been defined in the context of multi-agent systems. In this paper it is shown how these interaction protocols can be described in a reusable way for BPMN workflows. The underlying idea is to hide the complete message-based complexity of the underlying protocol specification and allow to employ them in a completely domain oriented fashion, i.e. the workflow modeler is only concerned with initiating a specific type of interaction and fetching the results. For this purpose the ideas of agent-based goal-oriented interactions have been simplified and transferred to the workflow modeling area. The usefulness of the approach is exemplified by an example that illustrates how contract-net negotiations can be set-up. |
