中文摘要：

水电工程导流的成败与导流标准的选择密切相关，它直接影响到主体工程的建设。文章分析了水电工程施工初期导流标准选择的控制性因素，采用了因素定量化方法，将物元分析运用到多目标决策中，建立了施工初期导流标准多目标决策模糊物元分析模型，并给出了实例，为多目标决策水电工程导流方案提供了新的思路。

英文摘要：

The success and failure of river diversion for hydropower projects is closely related with the choice of diversion standards that directly affect the construction of main works. It analyzed controlling factors in selection of initial construction diversion standards, adopted factor quantitative method to apply the object element analysis to multipurpose decision, established the fuzzy object element analytic model for the multipurpose decision of initial construction diversion standard, and gave examples so as to provide a new philosophy for the construction diversion scheme of multipurpose decision in hydropower projects.
