工作流重构技术研究

Study of Refactoring for Workflow

先进的工作流技术与传统的企业管理信息系统相结合,日益成为提高企业信息化的一个重要手段。目前的工作流是基于模型驱动的,定义一个完整的模型是相当复杂和费时的;而且,实际业务流程同流程模型之间必然存在差异。本文介绍了工作流网,工作流日志的概念;提出了一种基于日志包含的信息来重构业务流程模型的算法,该算法还能处理日志中的干扰信息和有效地度量流程模型和实际业务流程之间的差异。

It is increasingly important for Enterprise to combine the advanced workflow techniques and legacy information system. Current workflow management systems are driven by process models. It is often complicated and timeconsuming to define a workflow process model and typically, there are discrepancies between the actual workflow processes and the processes as perceived by the management. Workflow log contains information about all workflow events. We assume that each event refers to one task being executed for a single case. The algorithm presented in this paper induces the actual workflow model through the runtime workflow logs. It can also deal with noise and measuring the discrepancies between prescriptive models and actual process executions.
