【摘要】：近年来,福建省木材制品的消费需求量呈现较快的增长势头。在激烈的市场竞争之下,福建省木材企业面临着巨大的机遇与挑战。由于木材企业的生产水平逐步趋同,物流水平的高下已成为其能否在市场竞争中取得优势地位的关键因素。但是长期以来,福建省木材企业普遍存在着重视生产、轻视流通的现象,导致其缺乏对于木材物流的了解与研究,因此大多数木材企业依然处于成本高、效率低的传统的、落后的物流管理模式之中。降低库存与运输的成本是控制企业物流成本的核心要素,对于福建省木材企业来说,其物流系统中的库存和运输这两大环节依然根据传统的方法进行决策和运作,也是导致其物流成本过高、物流水平低下的重要原因。结合福建省木材企业的需要,在资金有限、技术水平进步不大的情况下,对库存控制和运输决策进行优化研究,从而促进福建省木材企业的物流成本最小化、物流水平的提高是一个迫切需要解决的问题。本文聚焦于福建省,将省内木材企业的库存与运输两个子系统作为研究对象,为了实现物流成本的最小化,采用定量、定性分析以及案例实证等方法,谋求优化福建省木材企业库存控制与运输决策。本文分析福建省木材企业的物流现状和问题,结合了MRP、EOQ等方法,运用运筹学的相关知识探讨了如何对福建省木材企业进行库存控制与运输决策的优化。其次,对于库存,运用MRP方法,根据需材企业的主生产计划、产品结构关系等,对木材企业进行库存优化。同时,考虑到木材企业库存实际存在连续与离散两种随机需求,选取与第三方物流企业进行联合库存控制的方式,以EOQ模型为基础建立优化模型。再次,对于运输,本文以运输费用最小化为目标,讨论了直达、中转和混合三种模式的优化模型。然后,综合以上两大关键问题,构建了福建省木材企业的库存控制与运输决策的优化模型。最后,文章运用LINGO优化软件以福建省某木材企业为例进行实证分析。结果表明,利用本文的模型对木材企业进行库存控制与运输决策的整体优化,可以较大程度地降低成本,全面提高木材企业物流系统的运作效率,优化效果显著,具有现实意义。
[Abstract]:In recent years, Fujian Province wood products consumption demand is showing rapid growth momentum. Under the fierce market competition, Fujian Province wood enterprises are facing great opportunities and challenges. Due to the gradual convergence of wood production level of enterprises, level of logistics has become a key factor in its ability to achieve a dominant position in the market competition. But for a long time, Fujian Province wood enterprises are generally attach importance to the production, circulation despise phenomenon, leading to a lack of understanding and research of timber logistics, so most timber enterprises are still at the high cost and low efficiency of the traditional, backward logistics management mode. To reduce the inventory and transportation cost control is a core element of enterprise logistics the cost for the timber companies in Fujian Province, the two part of the inventory and transportation in logistics system is still based on the traditional method and decision making Operation, but also lead to the high cost of logistics, an important reason for low level. With the need of logistics enterprises in Fujian Province wood, limited funds, technology progress is not the case, the optimization of inventory control and transportation decision, so as to promote the Fujian Province wood to minimize the cost of logistics enterprises, improve the level of logistics is a an urgent need to solve the problem. This paper focuses on Fujian Province, the two subsystems of timber inventory and transportation enterprises in the province as the research object, in order to minimize the logistics cost, using quantitative and qualitative analysis and case study method, to optimize Fujian Province timber enterprise inventory control and transportation decision-making. This paper analysis the status and problems of Fujian logistics timber enterprises, combined with MRP, EOQ and other methods, using relevant knowledge of operational research to explore how to Fujian Province wood enterprises inventory control The optimization of preparation and transportation decision-making. Secondly, for inventory, using the MRP method, according to the master plan for material enterprises, product structure relationship, inventory optimization of timber enterprises. At the same time, taking into account the actual timber inventory of two kinds of continuous and discrete stochastic demand, selection of joint inventory control mode and third party logistics enterprises based on EOQ model and optimization model is established. Thirdly, the transportation, the transportation cost minimization as the objective function, discusses the direct optimization model of transit and mixed three modes. Then, based on the above two key problems, establish the optimization model of inventory control and transportation of timber enterprise's decision in Fujian province. At last, the article uses LINGO optimization software to a timber enterprise in Fujian Province as an example of empirical analysis. The results show that the inventory control and transportation decision-making of enterprises using this model of wood The overall optimization can greatly reduce the cost and improve the operational efficiency of the logistics system of timber enterprises, and the effect of optimization is significant, and it is of practical significance.
