Method for Flexible Workflow Modeling Supporting Task Change and Performance Analysis

The flexible workflow can be rapidly and flexibly adapted to the dynamic change and the exception management in the enterprise business process. Based on the analysis of the generating reason of flexible workflow, the main reason of change and exception affecting the flexibility of the workflow is compared, the composition and representation method of the flexible workflow based on stochastic Petri nets are described in detail; And a modeling method for flexible workflow is proposed; Finally with a B/S based ELMS system, an example of the modeling method for flexible workflow is demonstrated.
