The Research Of Running Mechanisms For Workflow Management System Working In Dynamic Allied Environment And Based On Multi-agent Technology

Globalization and infomationization are the main reasons to the fundamental changes in enterprise environments. Wherein, the emergence of dynamic-virtual enterprise has imposed further requirements on the traditional management system, control method, organization structure and decision making criteria.Agent, itself, is self-governing, socialism, responsive, mobile and active. It is based on said characteristic that has made agent a key to a smart, mobile and dynamic computer environment, as well as capable of enhancing the functionality of any workflow systems to satisfy the dynamic-virtual enterprise requirements once adopted. Multi-agent technology plays a crucial role and is considered as the main technical basis in the research of dynamic-virtual enterprise workflow system. This thesis focuses on the running mechanism of the multi-agent workflow management system that supports dynamic-virtual enterprise.The paper starts by analyzing the model of multi-agent workflow management system that participates the dynamic-virtual enterprise, and then gives it preliminary insight into model that are developed based on multi-agent. Guiding by this model, we research it communication mechanism such as the KQML language, blackboard, point to point connection and so on.Meanwhile, we study it harmonious mechanism including the decompounding of allied task and cooperating based on contract net, and last we offer an improved contract net protocol that supports cooperative solving among many agents by inviting biding, biding for,sending out bid and execution.Besides,this paper discusses the logical structure and realization of contract net indetailed.Then, we offer the model of it transaction processing and abnormity including the states of transaction, ACID features,introduction of advanced transaction model,workflow transaction, transaction restriction and the analysis for definition, description, disposal of abnormity.At last, we summarize this paper and prospect the future work based on this technology.
