摘要： 提出了一种虚拟企业风险评价的有效方法.针对虚拟企业以项目为组织模式及信息具有不确定性的特点,为考虑项目时间因素对整体风险的影响,基于计划评审法建立了虚拟企业风险评价模型.在已知风险水平与各工序作业时间的对应关系、每个工序的模糊风险水平以及风险水平与项目完工时间的对应关系的基础上,通过项目不同风险水平的完工概率描述企业的整体风险状况,实例研究表明该方法为虚拟企业风险评价提供了一种有效的管理工具.

Abstract: An effective risk evaluation method for virtual enterprise is proposed. Focused on the characteristics of the project organization mode and the uncertain information, by considering the effect of time on entire risk of virtual enterprise, the model of virtual enterprise risk evaluation is established based on program evaluation and review technique. The entire risk of the enterprise is described by the project complication probability under different project risk level while the relationship between the risk level and the process time of each process, the fuzzy risk level of each process, and the relationship between the risk level and the process time of the project are known. The example analysis demonstrates that the method is an effective management tool for virtual enterprise risk evaluation.
