Evaluation Model of Dynamic Risk for Single Procedure in VE
,-0001,():
With the rapid development of Internet and the emerging of global economic, VE (Virtual Enterprise), which is the alliance of stand-alone enterprise and usually organized in project mode, becomes a new paradigm of enterprise operation. On the one hand, VEs can help enterprises to respond rapidly to market demand by sharing capabilities, resources, and so forth. One the other hand, enterprises in a VE face more risks than conventional enterprises. Moreover, the risks in VE are always dynamic. Hence, risk management for VE has received many attentions. Risk evaluation is one of the key phases for the risk management. In this paper, focus on the characteristics of project organization mode and dynamic risk of VE, the evaluation model of dynamic risk for single procedure in VE is presented based on the Markov process. In the VE, the operation of each procedure is composed of different process, and there are many states within each process. The procedure passes these states randomly and the time needed, the quality and the cost needed within each state are different, so the risk is dynamic. The Markov process is used to describe this process, and case study suggests the effective of the method.
