Economy Risk evaluation of virtual enterprise’s task decomposition based on fuzzy-linear program and entropy evaluation method
نویسنده
چکیده
Virtual enterprise can not only enhance an enterprise’s competitiveness but also increase risks it faces. According to the principles of virtual enterprise’s risk analysis and control, this paper decomposes virtual enterprise project into several tasks (nodes) and establishes virtual enterprise’s nodes as well as the whole alliance’s risk evaluation model. Then, it uses weighting method combining subjective method with objective method based on fuzzy-linear program to determine the weight of each evaluation indicator and respectively conclude the risk degree of each project node, and then, it adopts transfer entropy to calculate the weight of every expert who participates in the evaluation and summarize the risk degree of each node. At last, the paper figures out the whole alliance project’s comprehensive risk degree, introduces cases with representative significance and verifies the feasibility of the model, which can be closer to the objective reality.
