| 摘要: |
| 知识在多个参与者之间的产生、传播与应用称为知识流.在知识密集型组织中,对业务过程的控制和对知识资产的管理具有紧密的依赖关系.工作流管理是实现业务过程控制的重要技术.当前的工作流过程元模型不支持对知识管理机制的表示.为此,提出了一个扩展的工作流过程元模型,以支持业务过程控制与知识管理的集成.在此基础上,对知识流的建模与控制进行了深入的研究.提出了一种知识流建模方法,通过5类知识流单元对知识传递与重用、人员协作与交流进行表示.针对知识流中的动态因素,研究了基于资源约束、知识需求变化和时间约束的知识流控制方法,以实现自适应的知识流控制,并给出了有关算法.为工作流技术与知识管理技术的有效结合提供了一个有益的途径. |

| Abstract: |
| Knowledge flow is the knowledge creation, distribution, and reuse among participants. In knowledge intensive organizations, business process control and knowledge assess management are closely related to each other. Workflow management is an important technology for business process control. Yet knowledge management mechanisms can not be represented by current workflow process definition meta models. An innovative extended workflow process definition meta model is first proposed for integrating the above two aspects. Based on that, modeling and control of knowledge flows are studied. A knowledge flow modeling approach is proposed by using five kinds of knowledge flow components to represent knowledge distribution and reuse, cooperation and communication among participants. To deal with dynamic elements in knowledge flows, an adaptive knowledge flow control approach with corresponding algorithms is proposed based on resource constraints, changes of knowledge requirements, and time constraints. This paper presents a beneficial approach for the effective integration of workflow and knowledge management technologies. |
