| 摘 要： | 为克服传统施工安全评价方法不能解决的评价指标和事故的映射关系、定权和变权、随机性和模糊性等问题,围绕水电工程施工过程,建立施工与运行相耦合的安全评价指标。通过引入粗糙集理论,将具有随机性和模糊性的事故原因数据化,利用粗糙集理论简化施工安全评价指标,确定最小评价指标集及耦合权值,使得无规律的给定的数据具有研究的价值,从而使得评价方法具有近似函数的功能,达到从定权向变权科学的过渡。结果表明:利用粗糙集理论可以确定水电工程施工中的安全指标权重,有效降低安全评价成本,对于水电工程施工安全评价具有很好的应用价值。

| Abstract: | To overcome the problems that traditional safety evaluation method for hydropower construction can't solve the mapping relation between evaluation index and accidents,and index's fixed weight,variable weight,randomness and fuzziness,coupled safety evaluation indexes for hydropower construction are established.Then rough set theory is used to make the fuzziness and randomness of accident causes digital and to determine the minimum index set and its coupled weight.This makes the ruleless given data be of more... |
