Research And Application Of Workflow Management System Based On Muti-Agent Interactive Cooperation

With the rapid development of computer internet technology and the boost popularization of using the management information systems for fields of business and production and etc.,workflow technology is introduced gradually,workflow management system is produced with application and the hot tidal wave is brought. Some shortcomings of the traditional workflow management system are exposed with the automation degree of modern enterprises has been constantly enhanced such as the high degree of coupling,low flexibility and weak artificial intelligence.Hence,how to solve the problem mentioned above in effect is the key problem of workflow management system for further development and application.The concept of "Agent" starts from 1970s and growing up in late 1980s which becomes a active research direction in the field of computer science.Generally, "Agents" have autonomous,interactive,reactive and proactive features.There has a loosely coupled relationship between different Agents.Therefore,the combination use of "Agents" and "workflow management systems" will definitely inject new vitality for the development of workflow management systems.This paper discussed the basic concepts of workflow management systems and Agent technology.It also analyzed the reference model of workflow management system,the Agent-based systems,and the multi-Agent co-operation system model. It focused on an analysis of current workflow management system's deficiencies,the future directions and the Research & development of multi-Agent System.Based on the above theory,this paper puts forward a model based on cooperation of multi-Agent workflow management system(MAWFMS),the business logic will be separated from the system by designing agents with different features,and leading to improve scalability and easy maintenance of the system.The paper also described designing ideas of MAWFMS model and combined with the workflow management system structure,which given by the League of Workflow Management System,the design and performance of a MAWFMS Model with the overall architecture have been detailed analyzed in this paper as well.In this design,the new MAWFMS model adds a new function of intelligent task allocation decision-making.Leading AHP into the distribution of tasks,expanding the traditional allocation of workflow task model—"push" model and "pull" mode and achieve an "Intelligent Decision" mode.By introducing the Intelligent Agent,making intelligent decision,the system will allow right persons to do right tasks,which strengthen the performance of the management system,and this is the first Creative point.The second point is,in the design of Agent communication module,by using of XML technology to package KQML language,XML will be embedded in the content of KQML layer,using XML to express the semantic content of the information,enrich the semantic of KQML,achieve the complexity of the semantic easily expression simplify the Agent Communication's complexity.The Third creative point is,leading an aspect-oriented programming design concept into the system authorization module, by uncoupling the system authorization module from core business modules to an encapsulation,and dynamically embedding the authorization module under AOP framework when core business modules are called,we realize a universal,maintainable and extendable authorization module.At last,a real application of MAWFMS—the staff performance appraisal system, has been referenced in this paper to verify the model's availability.
