| Abstract | Today's business enterprises must deal with global competition, reduce the cost of doing business, and rapidly develop new services and products. To address these requirements, enterprises must constantly reconsider and optimize the way they do business and make the best use of their information systems, applications and enterprise constraints and knowledge to support evolving business processes. Therefore, there is a need for the integration of workkow technology and knowledge management technology. In this report, we present the design and implementation of a workkow model-ing and simulation system (WFMSS) based on an extensible object-oriented knowledge base management system, OSAM*.KBMS. In particular, we add modeling constructs to the underlying object model of the KBMS for modeling the control structures of workkow processes and use event-condition-action-alternative action rules to specify constraints associated with these processes. For "every" participant in real life workkow process, a corresponding construct has been added, and because of this one-to-one correspondence, process modeling is made simpler. To facilitate workkow modeling, a graphical tool is being developed under a separate eeort and the graphical representations of process models are used to generate their textual representations posed in a workkow deenition language (WFDL). Unlike most of the traditional workkow systems, which follow the interpretive approach for enacting a workkow, we follow the compiled approach. The data and process modeling facilities of the KBMS are used to model data entities and work processes and a Code-Generator module of the KBMS compile and generate an exe-cutable process controller for each workkow process model. In the simulation mode, the process controller is executed and data are gathered and analyzed to validate the corresponding workkow process. Based on the analysis, the process model can be modiied to avoid bottlenecks or to improve performance. The validated process 1 model can then be used to control the activities of a real world business operation. In this work, workkow enactment is based on active rules. A developed active knowledge base management system is used for modeling and processing workkow processes. |
