摘要
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。
The mathematics model of Earth-rock Allocation System was established which was aimed at the minimization of the cost.The problem of earth-rock allocation could be viewed as a linear programming problem,and LINGO was a professional optimization software to solve the mathematics programming problems,such as the linear programming and integer programming.The paper applied LINGO into the field of earth-rock allocation on railway station.The result showed that using Lingo to solve this problem had obvious advantage.Therefore the LINGO was a effective method to solve the problem of earth-rock allocation on railway station.
