Ore distribution plan of Metallurgical CompanyAbstract In this paper,a series of optimization models are established by selecting the oredistribution quantity and the average grade of each ore point as the starting point.Taking theaverage grade after mixed ore distribution as the evaluation standard,the tonnage of each orepoint that should be distributed is given,and the practical problem of how much ore distributionquantity can obtain the best benefit of the company is solved.First,LINGO software was used to build an optimization model and calculate the ore quantityof 14 sites.The best value is 141.9 million tons.It can be seen from the results that except the firstore spot,all the other 13 ore spots can be extracted,and the grade value of iron in the first orespot is the lowest.The average grade of iron is higher than 45%after all other ore spots areextracted.Only the ore distribution quantity of the first ore spot has the greatest influence on thefinal average grade,so it can make the final average grade not less than 45%when the oredistribution quantity of the first ore spot should be less than 31.120 tons.The sensitivity analysis iscarried out by lingo software to solve the practical economic problem of the company's bestbenefit.In a word,this paper synthesizes all aspects of consideration,which is more in line with thereality,so it also has great use value in the future real lifeKey words:With ore The average grade of copper Lingo The sensitivity
