以土石方调配系统的总费用最低为目标,建立通用的站场土石方调配问题的数学模型。由于土石方调配问题可以归结为一个线性规划问题,而Lingo软件是一种专门用于求解数学规划问题的优化计算软件,可用于求解线性规划和整数规划问题,将该软件应用于站场土石方调配领域,并通过一算例进行了验证。结果表明,运用Lingo软件解决土石方调配问题具有显著的优越性,是解决大规模土石方调配问题的有效途径。
With the lowest total cost of earthwork allocation system as the goal, a universal mathematic model of earthwork allocation problem in station yard is established. Because the earthwork allocation problem can be attributed to a linear programming problem, Lingo software is an optimization calculation software designed to solve the mathematical programming problem, which can be used to solve the linear programming and integer programming problems. The software is applied to the earthwork allocation field , And verified by an example. The results show that using Lingo software to solve the problem of earthwork allocation has obvious advantages and is an effective way to solve the problem of large-scale earthwork allocation.
