摘　　要：工程项目的风险评价是其建设和运营的关键。针对评价过程中指标权重确定问题,构建一种基于Vague集和熵综合赋权的方法,通过Vague集理论设计主观权值的计算方法,结合熵权法求得的客观权值,以偏差平方和最小化为判断标准进行指标最优赋权,在此基础上结合可拓评价法建立综合赋权评价模型并应用于工程项目的稳定性评价中。实例结果表明,综合权值能够合理表征各指标的影响程度,可拓评价模型对储气库稳定性的判断结果符合实际情况,并且能够得出造成储气库不稳定的缺陷指标,便于运营机构进行针对性的整改,该模型可以为工程项目的评价管理提供有效的参考。For the weight values of each index in the extension method, this paper presents the comprehensive weight computation method based on vague sets and entropy. The method devises the subjective weights based on vague set theory, combines with the objective weights calculated by entropy method, and gives the optimal weights by minimizing the sum of squares of deviations. On the basis of the optimal weights we establish the extension model to evaluate the stability of projects. The case results show that the comprehensive weights can characterize the effects of each index reasonable, the evaluation result of the storage is in line with the actual situation, and also get the defects indexes which can be improved by management mechanism. Therefore the method can provide reasonable reference for the project evalu- ation.
