Reengineering has enabled companies to operate faster and more effectively and to use information technology more productively. A workflow model is useful for business process analysis, and a well-built workflow can help a company streamline its internal processes by reducing overhead. However, very few modeling experts encounter the same case more than once in their entire career; modeling experience is valuable and hard to acquire. Therefore, the results of workflow modeling need to be managed as information assets in a systematic fashion. Reusing these results is likely to enhance the quality of the modeling. The Case-Based Reasoning (CBR) technique is quite helpful for the reuse of knowledge. CBR is a problem solving technique that reuses past cases, experiences, or tacit knowledge. CBR retrieves similar cases from a case base, selects the most similar case among them, adapts this case according to the user’s requirements, and then stores this new case into the case base for future reuse. Although CBR is effective for the reuse of knowledge, it has not bee
