张家口煤矿机械有限公司库存成本优化研究

在张家口煤机厂的库存成本管理中,库存物料种类繁多,配件数额大,库存管理比较滞后,造成库存成本较高.本文以多级库存成本模型为基础,结合张煤机的库存实际状况,以张煤机库存总成本最低为目标,建立以订货量（或生产量）为参数的新的库存模型,并运用模拟退火算法,利用matlab详细的讨论了该库存模型的求解算法,算出最优订货点（或生产点）、安全库存以及最优订货量（或生产量）等库存参数,拟达到降低库存成本,提高库存周转率,优化张煤机现行库存的目的。最后给出了应用算例。

The Research of Zhangjiakou Coal Mining Machinery Co., LTD Inventory Optimization

During the management of Zhangjiakou coal mining machinery co., LTD, there are many different kinds of inventory materials and the amount of accessories is large, inventory management lags behind, causing the cost of inventory is high. This paper is based on the multistage inventory optimization mode, takes the fact of into consideration, and takes the minimum inventory cost as the goal, at last, it sets up an inventory model parameters, and uses simulated annealing algorithm, it also uses matlab to discuss the algorithm of the inventory model, calculates the optimal reorder point inventory(production point), safety stock , and the optimal order quantity (production amount)and other parameters, intends to reduce inventory costs, improve inventory turnover rate, optimize the current inventory of the coal enterprise of Zhangjiakou. At last, it gives an application example.
