工作流知识管理系统工作流引擎的研究

Research of Workflow Knowledge Management System Workflow Engine

企业的知识管理是为了提高企业发展与知识传递,工作流系统是支持工作流定义、执行和监控的计算机软件系统。针对工作流系统应用在企业知识管理时面临的流程数据整合不易、文件内容词汇关系的不明确与存取控制不便等问题,提出了一种可应用于知识管理的工作流引擎架构。该架构以XML作为流程文件交换与存储的格式,将不同知识领域包含的概念及关联特性整合进工作流程中,并设计了基于角色继承的授权管理机制进行精确的文件存取控制。详细分析了工作流引擎的设计及实现机制,为工作流程中的知识管理提供了一种新的管理及控制模式。

The purpose of knowledge management of enterprise is to enhance the enterprise development and pass down the knowledge.Workflow system is computer software which supports workflow definition,performance and surveillance.When workflow system is applying in knowledge management,it faces the drawbacks including uneasy data integration,implicit definition of vocabulary,and inflexible control of authentication access.Put forward a workflow engine architecture.The architecture uses XML as the format of file exchanging and storage,integrates different domain knowledge＇s concept and relation into the workflow,and designs an authentication mechanism based on role inheritance to achieve accurate file access control.Introduce it carefully.The architecture brings a new control model for knowledge management in workflow.
