工作流管理系统WFlow中协同建模工具的研究

在传统的工作流管理系统中建模工具一般只支持单用户工作，工作流模型由专业建模人员来建立。随着工作流管理系统应用领域和应用规模的不断扩大，其所管理的企业业务流程已不可能只局限在企业中的一个小部门内部，而是一些跨部门跨企业的业务流程，这些流程只靠单个专业 建模人员已经很难完成其工作流模型的建立，它需要不同人员的分工合作，充分利用各自的专业知识共同来完成其工作流模型的建立。为此，开发了工作流管理系统－－Wflow，就其协同建模工具进行了研讨。

STUDY ON COLLABORATIVE MODELING TOOL IN WFLOW

Until recently, little attention has been paid to the collaborative modeling in most of conventional workflow management systems. Workflow models must be designed by professional modeling designers. With workflow management systems used in industry becoming increasingly complex, the business processes managed by them are not only within an organization, but also across organizations. These business processes can not be modeled by a single modeling designer, because this can not make the best of the knowledge of experts in different domain. So that, we have developed a workflow prototype system Wflow recently, and a collaborative modeling tool has been developed. In this paper, the main techniques of this tool implementation are discussed, and a workflow model is presented. On this basis, multi agent architecture and concurrency control algorithms are presented to support collaborative work for group.
