| Summary: | 碩士 === 國立成功大學 === 製造工程研究所碩博士班 === 93 === Enterprise performs many complex and inter-related business workflows to satisfy customers’ requirements and meet market changes. Proper workflow management can improve the business performance and competitiveness of the enterprise. However, the problems of workflow occur as the complexity and number of workflow increase. The smoothness and stability of workflow operation are therefore one of the main objectives of workflow management, and that highly depends on a well developed exception handling mechanism.
The objective of this research is to develop an exception handling mechanism for workflow management. Based on workflow operation analysis and exception classification, this research first proposes an exception handling strategy, method and technology using an semi-automatic exception handling strategy. The strategy provides a more flexible mode for exception handling. A rule based solving method and a case based solving method are then developed for exception handling. In the case of rule based solving method, an exception rule pattern is designed based on ECA syntax structure. In the case of case based solving, fuzzy logic is employed to calculate attribute-value-similarities, and the similarities of cases are then computed based on all of the attribute-value-similarities to find out a suitable historical case(s) for reference.
This paper also presents an integrateable exception handling architecture for workflow management. Based on this architecture, an exception handling algorithm for workflow management is developed with the results of the handling process so as to accumulate tacit knowledge and experience. The results of this research well help improve the performance of business workflow and thus enhance enterprise competitiveness.
