The effective implementation of workflow system in manufacture enterprises enables the enterprises to achieve the benefits associated with the integration, automation and management of their business process. The conventional workflow model based approaches hinder the change of workflow logic flexibly. These approaches face difficulties in satisfying the changing market demands, meeting the demands from intensifying market competition, and adopting new information technology development. After the analysis of the demand for a flexible workflow modelling approach and the characteristics of workflow flexibility, a dynamic workflow modelling framework based on a directed graph theory is proposed in this paper to model the flexible workflow. The key elements of the framework are explained and the modelling approach is described. Using the approach, the changeable business process can be modelled flexibly and concisely without the need of redefinition of workflow model. Finally the paper describes the implementation of the flexible workflow model using a Web-based flexible customer service system.
