考虑外部条件的某堆石坝料场规划方法及应用

Material Yard Planning Method of Rockfill Dam Considering External Conditions and Its Application

针对传统的料场规划方法未将综合效益最大作为规划目标的不足,考虑料场规划中存在但难以量化的外部性因素,采用层次分析法确定各外部因素的优先度,并以料场调配总费用最低为优化目标,建立线性规划模型,利用Matlab求出在考虑外部因素时料场规划的最优解。实例应用结果表明,该方法可实现综合效益最大,更符合工程施工要求。

For the shortage of the traditional material yard planning method not taking maximum of comprehensive benefit as the objective,considering external factors which exist in material yard planning but it is hard to quantify,analytic hierarchy process（AHP）is used to determine the priority of external factors.And then linear programming model is established by minimizing the material yard allocation cost.Finally,optimization solution of material yard planning is obtained by Matlab with considering external factors.The example application results show that this method can achieve the maximum comprehensive benefit and it more conforms to the requirements of engineering construction.
