摘要
工作流模型是工作流管理系统的核心和基础,许多方法可以应用于建模过程,但是这些方法缺少对制造过程,尤其是网络化制造过程的有力支持,不能满足制造领域工作流建模的要求。通过对现有面向制造工作流模型的改进,提出一种新的模型,包括四个子模型:基于多色集合理论构建过程模型,实现过程元素的分离,提高模型定义的动态性;基于Web服务的能力模型提供制造能力的服务;从用户角度出发,约束模型建立评价服务和流程的相对指标;通信模型以SOAP为基础保证模型的信息交互通畅。提出的基于制造能力的工作流模型适合于组织松散耦合、模型动态构建、信息分布定义的网络化制造环境。
Many methods can be applied in workflow modeling,but they lack powerful supporting to manufacturing process ,especially for virtual enterprise. A new workflow model is proposed through im- provement of current models faced to manufacturing. The new approach includes four sub models. The first one ,a polychromatic based process model,improves dynamic ability of modeling by separately definition of nodes,edges and their attributes. The second one is a capability model based on Web service. The third model called constraint model gives relative index for service and process assessment. The last one applies SOAP for well communication inside and outside of workflow model. The model is suitable for environment of loosely collaboration, dynamic construction and separately definition.
