【摘要】：全球化信息网络和全球化市场的形成以及技术变革的加速,导致我国煤炭产业的市场竞争也日趋激烈,经济市场的波动给某煤炭企业带来了新的挑战和机遇。在这种环境下,某煤炭企业为更好的适应新形势,使管理运营机制逐步与国际接轨,其研究重点开始转移到物资库存管理方向。本文对该煤炭企业库存现状进行分析以后,发现呆滞物资无论从库存种类或者库存金额方面考虑都是库存物资中举足轻重的一部分,成为本文的研究重点。首先将呆滞物资按照共享性质分为可共享呆滞物资和不可共享呆滞物资两种。随后根据各自存在的特点分别对其进行ABC分类、基于APH的ABC综合因素分类,并结合分类结果提出相应的库存控制策略,限制最大库存量,从策略上控制库存数量。在上述研究的基础上,进一步对不同类型的呆滞物资进行深入研究,利用遗传算法确定其在两级库存模式下的最优库存量分布,从根本上控制呆滞物资的库存数量,实现降低库存成本的目的。该煤炭企业呆滞物资的库存控制策略以及库存量分布确定,有利于该企业库存管理水平的提升,库存成本的下降。本文提出的分类方法、遗传算法将理论与实践相结合,既能补充呆滞物资库存优化研究领域的空白,具有一定的指导意义,又能运用到该企业日常物资管理工作来,还具有非常重要的现实意义。图16幅,表29个,参考文献57篇。
[Abstract]:The formation of globalization information network and the globalization market and the acceleration of technological change have led to the fierce market competition in China ' s coal industry . After analyzing the status of the inventory of the coal enterprise , this paper finds that it is an important part of the inventory material , whether from the stock type or the inventory amount , to be the focus of this paper . Firstly , the static materials are divided into two kinds of shareable and non - shareable materials according to the characteristics of sharing . Then , according to their respective characteristics , ABC classification is carried out , based on the ABC comprehensive factor classification of APH , the corresponding inventory control strategy is put forward according to the classification result , the maximum stock quantity is limited , and the quantity of inventory is controlled from the strategy . On the basis of the above research , further research on different types of dull materials is carried out , and the optimal inventory distribution in the two - stage inventory mode is determined by using the genetic algorithm , so that the inventory quantity of the stagnant material is fundamentally controlled , and the purpose of reducing the inventory cost is realized . This paper puts forward a classification method based on the genetic algorithm combining theory with practice , which can supplement the blank of the research field of inventory optimization of the sluggish material , and has a certain guiding significance . It can also be applied to the daily material management of the enterprise , and has very important practical significance .
