【摘要】：控制库存的根本目的是减少资源浪费，合理利用有限资源，降低物流的总成本，让企业获得更多的利润。目前我国从事危险化学品销售的企业普遍面临着库存量高、库存信息不准确、库存周转率低以及流动资金占有量大等诸多问题。然而，通过分析国内外相关文献可以发现，对于危化品企业库存管理的研究无论是从深度还是广度上来说，都远远落后于一般产品库存管理的研究。鉴于此，研究控制危险化学品零售企业的库存控制相关理论与方法对企业的经营起着非常重要的作用。本文以危化品零售企业为研究对象，研究库存控制问题。对近年来传统库存控制理论的相关文献进行了系统研究，归纳总结有关需求下的库存、随机库存、服务水平约束下的库存等内容。分析介绍危化品零售企业的库存要求、库存管理与安全。首先，考虑到大多数文献没有考虑危险化学品的特殊性，为了更好地结合理论与实际，将市场分割成高需求和低需求两类，以库存成本最小化为目标确定最优订购量，加入“过期处理费用”和“库存的危险成本”两个要素建立具有危化品特性的库存模型。结合具体算例证明完善后的模型的有效性。其次，由于现实中零售企业在面向大客户时可能会制定优先消费的策略来保护他们的利益，针对上述情况，建立了在两类需求不同服务水平状态下，以及随机的补货前置期的(s, S)库存系统模型，以此探讨最优库存的控制方法，并通过参数的敏感性分析来解释现实管理中的一些实际现象。最后，，本文对所做的工作进行总结，指出一些仍存在的问题，并展望未来可深入研究的方向。
[Abstract]:The fundamental purpose of inventory control is to reduce the waste of resources, reasonable use of limited resources, and reduce the total cost of logistics. At present, the enterprises engaged in the sale of dangerous chemicals in our country generally face a lot of problems, such as high inventory, inaccurate inventory information, low inventory turnover and large amount of liquid capital. Through the analysis of domestic and foreign related literature, we can find that the research on inventory management of dangerous chemicals enterprises is far behind the research of general product inventory management in terms of depth and breadth. In view of this. It is very important to study the theories and methods of inventory control in the retail enterprises of dangerous chemicals. In this paper, we take dangerous chemicals retail enterprises as the research object, study the inventory control problem, study the related literature of traditional inventory control theory in recent years, summarize the inventory under the relevant demand, random inventory. Analysis of inventory requirements, inventory management and safety of hazardous chemicals retail enterprises. First of all, considering that most of the literature did not consider the particularity of hazardous chemicals. In order to better integrate theory and practice, the market is divided into two categories: high demand and low demand, and the optimal order quantity is determined by minimizing inventory cost. Add "out-of-date treatment cost" and "dangerous cost of inventory" to establish inventory model with dangerous chemicals characteristics. Combined with specific examples to prove the effectiveness of the improved model. Secondly. Because retail enterprises may make preferential consumption strategies to protect their interests when facing large customers in reality, in view of the above situation, the two types of demand under different service levels are established. And the stochastic inventory system model of pre-replenishment period, so as to discuss the optimal inventory control method, and through the sensitivity analysis of parameters to explain some practical phenomena in the real management. Finally. This paper summarizes the work done, points out some problems that still exist, and looks forward to the direction of further study in the future.
