三、实例研究 现在来研究产销平衡运输问题,它系一类具有特殊结构、形成最早、应用普遍、求解简单的线性规划优化问题。 1、露采矿山引例 排土的最优化在露天煤矿企业的管理决策中是一项较复杂而重要环节。因排土费用占生产成本的比重较高,如何合理分配土岩量,分别运送到远近不同的排土场,它直接影响到排土费用或原煤成本的高低。因此, Third, the case study Now to study the issue of balanced production and marketing transportation, it is a type of special structure, the earliest formation, the application of universal, simple solution to linear programming optimization problem. 1, open-pit mining The best example of dumping in open-pit coal mining management decision-making is a more complex and important part. Due to the high proportion of the cost of soil removal in the production cost, how to distribute the soil volume rationally to different farms near and far, which directly affects the cost of dumping or the cost of raw coal. therefore,
