一、问题的提出修建土石坝工程,填筑工作量往往是很大的。在现有的运输工具条件下,根据供需关系,存在许多方案可供选择,怎样选择最优方案,使得运输总费用最省,是十分有意义的。本文就这个问题在理论上作一些探讨,并建立起数学模型及解算方法。 First, the problem raised Building earth dam project, filling the workload is often very large. Under the existing means of transport, there are many options to choose from based on the relationship between supply and demand. It is of great significance how to choose the optimal solution so that the total cost of transportation can be saved. In this paper, this issue in theory to make some discussion, and to establish a mathematical model and solution method.
