Research On Technology Of Knowledge Flow System

On account of highly competitive and ever-changing nature of business environment in recent years, the enterprise began to emphasize the approach of Knowledge Management. The focal point of research about Knowledge management concentrate on and recommend mostly the introduction of such problems as concept , characteristic , management tactics of Knowledge Management ,etc. in recent years, while, there is little research about the micro activity to Knowledge Management --knowledge flows. The research on knowledge flows , have certain enlightenment function on our study on Knowledge Management. This Article tried to research on Knowledge Management in term of Knowledge Flows and provide a kind of definition about knowledge flows. Petri net, as a kind of modeling tool, it's figure ability to describe procedure is very strong. Compares with a lot of other non-formalized block diagram technology, Petri net has accurate definitions and avoided fuzzy. This article tried to utilize Petri net modeling knowledge flows. Also, this Article tried to research on the access control about knowledge. A method named Role based Knowledge Access Control has been proposed. In the end of this paper, we use Service Oriented Architecture(SOA) to optimize the design of knowledge flow system.
