A Study Of Enterprise Workflow Management System

In order to improve the working efficiency of the enterprise ,reduce the production cost and make the level of management better , most enterprises establish the management of information systems which aid to complete the business process and occupy preponderant position in competition. However, most traditional information systems stress mainly the computer realization for the internal business process of enterprise ,they can improve the working efficiency of single person and make little sense for those which need cooperation among many persons or many departments .Along with the development of the information technology and administrative skill, computer the wide applications of network, The enterprise of workflows technology becomes a new research focus of the field of computer., it is a kind of course modeling and key technology of course management that technology workflows in the work, can use the system to combine with other effectively , produce various kinds of business administrative systems which accord with enterprise's demand. Adopt workflow technology as business administrative system that core develop, the biggest characteristic is its flexibility with height, according to the concrete demands of enterprises, produce the application software system in a flexible way fast, and when customer's business course changes, recombinate and meet customer's demands rapidly. With workflow technology going on deep research, all have important meanings to the information-based degree , operational efficiency and competitive power which improve enterprises of our country.The system belongs to practise hour hand system that requirements for enterprise developed while being in chang bai, it follows work that the wfmc puts forward workflow model standard , we have designed a workflow management accords with workflow? reference model?. According to architecture of? workflow management system given by Workflow Management Coalition?(WfMC), a workflow management system must include modeling tool, enactment service, management tool and user interface, among which workflow modeling is the basement. A certain workflow model requires certain kind of workflow system. Flow to system work of structure engine systematic core , it is it explain to what course define to offer; Control establishment of the course instance , activating , hanging up , stopping , etc; Control activity conversion of instance, including serial or operation that run side by side , is it flow relevant explanation of data ,etc. to work; Offer the interface which users operated of support; Maintain work is it control data and work flow relevant data , transmit work shed relevant datum among use or user to flow; Offer and is used for activating the outside application program and visiting the work to flow in interface of the relevant data; The function of course instance implementation offer and control , manage and supervise work to flow. First we introduced the background and the development of the technology of the workflow management??,also we introduced a series of the? specifications and criterions which include the reference model and some basic concept presented by the Workflow Management Coalition?. On having fully analyzed the workflow managements which developed by the domestic and international research structure and the software enterprises, we found? current products have some following deficiency?: 1,lack of the full support for the running of the business activity 2,lack of the abilityOf integrating the legacy system?;3,poor scalability?.4,poor? reliabilityOn absorbing the advantage of the current various workflow management systems?, we have designed the administrative system flows in a job based on b/s structure that j2ee builds up, adopt the framework great characteristic except overcome above work the shortcoming has shed most, and also the stability , security , reliable , high-efficient , easy to maintain improvement to the system. Is it down to build up because of this then, main function model in system customize , is it...
