多目标系统模糊决策法在导流标准

施工导流工程是施工组织设计中关键环节，而施工导流标准的选择是施工导流工程的核心，选择合适的施工导流标准可使水电工程施工达到安全可靠和经济可行相统一的目的。利用多目标系统模糊决策法进行导流标准的比选，综合考虑工程的导流投资、经济损失、施工强度等决策指标，建立导流标准的多目标系统模糊决策模型，计算各指标的相对隶属度，根据隶属度最大为最优的原则，选择最优的导流标准方案。实例分析说明，导流标准的多目标系统模糊决策分析模型是可靠的、合适的。

The Application of Multi-objective Fuzzy Decision Method in the Selection of Diversion Criteria

Construction diversion engineeringis a veryi mportant part of the construction organization design,and the selection of the construction diversion criteriais the core of the construction diversion engineering.The appropriate construction diversion criteria selection can obtainthe ai mof economy feasibility and safety.Inthis paper,multi-objective systemfuzzy decision methodis used to select the diversion criteria,which synthetically considers the decisionindexes,such as invest ment of diversion construction,economic losses,constructionintensity to establish a multi-objective systemfuzzy decision model.The relative subordinate degree of each indexis calculated to select the opti mal scheme according to the principle of the maxi mization of the subordinate degree.The case study illuminates that the multi-objective systemfuzzy decision method for diversion criteria selectionis reliable and appropriate.
