1、生产计划问题优化摘要某厂用一套设备生产若干种产品。工厂靠银行贷款筹集资金，现在为工厂制订合理、易行的生产计划，使得生产成本、准备费用以及储存费用之和尽可能小。(1)为了很好的解决稳定的、周期性生产计划问题，我们建立了非线性规划的模型。利用题中的条件找出各个约束条件，并且得出的费用最小的目标函数为：mins1s2c1x1t1c2x2t2212112121111111ttttxccttdxkrkr212121122222222ttttxccttdxkrkr(2)考虑到 n种产品时，只是在一个周期中轮换更替生产不同的产品，从而满足每天对 n中产品的需求，求解方法与思想与第一问相同。我们先在网上查找优

2、化一组数据进行验证。当n=2时，运用 LINGO软件求出最优计划如下：生产周期为 7天，甲连续生产 4天，每天生产 525 件；乙连续生产 3天，每天生产467 件。每个周期需要贷款的最少资金为182126.0。关键词：非线性规划约束条件目标函数 LINGO精品w o r d 学习资料 可编辑资料-精心整理-欢迎下载-第 1 页，共 9 页生产计划问题优化一 问题重述：某厂用一套设备生产若干种产品。工厂靠银行贷款筹集资金，根据市场需求安排生产，现考虑以下的简化情形：1)设生产甲乙两种产品,市场对它们的需求分别为d1,d2(件/天)，该设备生产它们的最大能力分别为U1,U2(件/天)，生产成本分

3、别为 c1,c2(元/件)。当改变产品时因更换零部件等引起的生产甲乙前的准备费用分别为s1,s2(元)。生产出的产品因超过当天的需求而导致的贮存费用，按生产成本的月利率 r 引起的积压资金的 k倍计算（每月按 30天计）。设每种产品的生产率都可以从零到最大能力之间连续调节，每种产品当前的需求均需满足。请您为工厂制订合理、易行的生产计划，使上面考虑到的费用之和尽可能小。2）考虑有 n种产品的情形，自行给出一组数据进行计算，讨论模型有解的条件。二 模型假设（1）在生产中，对甲、乙两种产品考虑稳定的、周期性的计划，不必考虑初始情况。（2）生产过程中，机器不考虑出现故障等影响产量的各种因素。（3）假设

18、 问题分析生产甲乙两种产品时，只需要考虑稳定的、周期性的变化，故在安排计划时可以把甲乙分别看作在这些周期中间的一个周期。要为该厂制订合理、易行的生产计划，使题中考虑到的各种费用之和尽可能小,需要考虑以下几个方面：4.1首先是成本费用问题，由于每种产品的生产率都可以从零到最大能力之间连续调节，为了简化模型，可让甲乙每天的生产能力一定，故只要保证每天满足需求即可。4.2 其次是考虑到在改变产品时要更换零部件，由此引起的生产甲乙前的准备费用，为了节省准备费，可以在一个周期里连续几天生产甲或乙。4.3最后是由产品过多引起的储存资金。为了减少费用，我们考虑在一个周期内单独生产甲时，既能满足生产时间内的需

19、求，又能使生产剩余的的产品刚好满足单独生产乙时每天对甲的需求量，也就是说在单独生产乙时期末，剩余量刚好为 0。同理，在单独生产乙时，剩余量也刚好能满足单独生产甲时每天对乙的需求量。（2）当生产 n种产品时，我们可以根据第一问得出的结果进行分析，只是变量多的问题，同样需要建立非线性方程。为了简便的给出最优计划，让n2时，在网上查找一组数据，并且进行优化，再用LINGO软件解最优解。五 模型建立与求解5.1.1 1）总生产成本：由题意可知，在一个周期内，单独生产甲时的总生产成本为c1x1t1在一个周期内，单独生产乙时的总生产成本为c2x2t2精品w o r d 学习资料 可编辑资料-精心整理-欢迎
