冶金公司的配矿计划摘要本文选取矿点的配矿量及各矿点的平均品位为切入点，建立了优化模型，以混合配矿后的平均品位为评判标准，给出了各个矿点应该配矿的吨数，解决了多少配矿量获得公司最佳效益的实际问题。首先，利用Lingo软件建立优化模型，求解出了在14个矿点应配矿量，从而达到最大的经济效益，最终解出最优值为141.92万吨。通过结果可以看出除了第一矿点外，其余的13个矿点均可全部提取，则发现第一矿点铜的品味值最低。在其他矿点全部提取后铜的平均品位都高于45%，只有第一矿点的配矿量对最后的平均品位影响最大，所以解出第一矿点应少于31.120万吨才可以使最终的配矿平均品位值不小于45%并利用Lingo进行了灵敏度分析，解决了公司最佳效益的实际经济问题。总之，综合了各方面的考虑，比较符合实际，因此在以后的现实生活中也有比较大的利用价值。关键词配矿量平均铜品位Lingo灵敏度OredistributionplanofMetallurgicalCompanyAbstractInthispaper，aseriesofoptimizationmodelsareestablishedbyselectingtheoredistributionquantityandtheaveragegradeofeachorepointasthestartingpoint.Takingtheaveragegradeaftermixedoredistributionastheevaluationstandard，thetonnageofeachorepointthatshouldbedistributedisgiven，andthepracticalproblemofhowmuchoredistributionquantitycanobtainthebestbenefitofthecompanyissolved.First，LINGOsoftwarewasusedtobuildanoptimizationmodelandcalculatetheorequantityof14sites.Thebestvalueis141.9milliontons.Itcanbeseenfromtheresultsthatexceptthefirstorespot，alltheother13orespotscanbeextracted，andthegradevalueofironinthefirstorespotisthelowest.Theaveragegradeofironishigherthan45%afterallotherorespotsareextracted.Onlytheoredistributionquantityofthefirstorespothasthegreatestinfluenceonthefinalaveragegrade，soitcanmakethefinalaveragegradenotlessthan45%whentheoredistributionquantityofthefirstorespotshouldbelessthan31.120tons.Thesensitivityanalysisiscarriedoutbylingosoftwaretosolvethepracticaleconomicproblemofthecompany'sbestbenefit.Inaword，thispapersynthesizesallaspectsofconsideration，whichismoreinlinewiththereality，soitalsohasgreatusevalueinthefuturereallife.Keywords:WithoreTheaveragegradeofcopperLingoThesensitivity目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc40558910"引言PAGEREF_Toc40558910\h1HYPERLINK\l"_Toc40558911"1.问题重述PAGEREF_Toc40558911\h1HYPERLINK\l"_Toc40558912"2.问题分析PAGEREF_Toc40558912\h2HYPERLINK\l"_Toc40558913"3.问题所应用的背景概略PAGEREF_Toc40558913\h3HYPERLINK\l"_Toc40558914"3.1线性规划的概略PAGEREF_Toc40558914\h3HYPERLINK\l"_To
