【摘要】：针对渠系工程的特点,确定了渠系施工工区划分方案决策的3个主要指标-物料运输费用、施工工期及施工难易程度指标,建立了施工区划分方案优选的灰色关联模型,通过层次分析法确定各指标的权重,使工区划分结果更合理,更全面。研究了场内物料运输适用的三大运输模型,根据渠系工程物料场内运输的实际特点,确定了场内各物料的运输模型,用线性规划的求解思想,利用lingo编程进行求解,确定了各类物料运输的最小总运费、物料调配方案及最短运输路径,对这类线状分布工程施工期场内物料运输方案优化选择具有指导意义。
[Abstract]:According to the characteristics of canal system engineering, three main indexes for the decision of division scheme of canal system construction area are determined, such as material transportation cost, construction time limit and construction difficulty degree index. The grey relational model of optimal selection of construction area division scheme is established, and the weight of each index is determined by analytic hierarchy process (AHP), which makes the division result more reasonable and more comprehensive. The three transport models applicable to material transportation in the field are studied. According to the actual characteristics of material transportation in canal engineering yard, the transportation model of each material in the field is determined, and the solution is carried out by lingo program with the idea of linear programming. The minimum total freight rate, material allocation scheme and shortest transportation path of all kinds of materials transportation are determined, which is of guiding significance for the optimization of material transportation scheme in the field during the construction period of this kind of linear distribution engineering.
