Multiagent systems for workflow

Abstract

Workflows are ubiquitous in business computing. They arise not only within an enterprise, but increasingly across enterprises as well—in situations such as virtual enterprises and applications such as supply-chain management. Although the importance of workflows as a basis for understanding and automating business activities is widely recognized, current workflow practice leaves much to be desired. To a large extent, this problem arises because of the rigidity of current technology, which does not accord well with the complex, heterogeneous, dynamic environments in which workflows are applied. Agent technology promises to alleviate many of these problems and hence enable adaptive workflows in realistic settings. We consider interaction-oriented programming (IOP), an approach to software engineering based on multiagent systems that we have been developing. We focus on one aspect of IOP, which deals with social commitments and enables agents to flexibly enact a multienterprise workflow by entering into and behaving according to their commitments to each other. The agents can cancel or modify their base-level commitments only if they satisfy the metacommitments that then go into effect.
