Research Of Workflow Engine And Its Dynamic Based On Multi-agent

As the development of Globalization, the enterprises'locations begin to scatter, the cooperation among departments grows intensive, and the demand of detailed information about daily activities increases dramatically. The traditional workflow management system cannot satisfy the practical need of modern enterprises, which promotes the appearance of a flexible, distributable and cooperative workflow management system. Because of its independence, sensitivity, mobility, initiative, and interactivity, Agent has served as a new technique to provide a complex, dynamic, distributable and smart system. The implementation of Agent technique in workflow can better solve the problems encountered in the development of workflow management system, and better satisfy the demands of modern enterprises. For the reason that the engine technology is the core of workflow management system, the multi-Agent workflow engine model becomes the main research object.This paper first introduces related theories about workflow and Agent technologies, explores and studies the basic knowledge, summarizes the deficiency of current workflow technology and demonstrates the characteristics of Agent technology. Furthermore, this paper makes elaborate analysis and study of current multi-Agent workflow engine, points out its deficiency and raises a more cooperative four-level multi-Agent workflow engine model. Moreover, this paper explores and studies the dynamic migration mechanism based on the model verification and workflow migration, and puts up correspondent algorithms. At last, through the virtualization of multi-Agent dynamic workflow engine, this paper verifies the validity and feasibility of theories and designs above.This paper introduces auxiliary Agents such as supervision Agent, analyzing Agent and migration Agent into Agent workflow model, builds up fault-tolerant mechanism, flow model verification mechanism, and migration mechanism, thus reduces human interference and improves the smartness, distributed character and flexibility. The model verification algorithm and migration algorithm raised by this paper solves the deficiency that traditional algorithm cannot be used in circulation track, and extends the engine's flexibility and dynamic. The results are meaningful in the practice of Agent technology in workflow engine.
