【摘要】：随着我国经济社会的不断发展和进步,人们对生鲜产品的品质要求越来越高。生鲜产品易腐性、时鲜性的特点使它对其库存和运输提出了更为苛刻的要求。作为整个供应链中最重要的产品承载单位,供应商和零售商所追求的目标是如何降低生鲜产品的损耗,从而可以进一步提高销售利润或降低成本。在现代物流体系中,供应商和零售商不应该再“各自为政”,只考虑如何将自身的利益最大化,而是应该达成一种共识,作为一个整体去服务社会,满足消费者。而供应商管理库存系统(VMI)就促成了供应商和零售商的联合。库存路径问题(IRP)是实施VMI策略过程中的核心问题,如何在一定的计划期内确定对各个客户补充库存的数量、时间以及车辆的行驶路径,在满足一定的约束条件下,使系统总运行费用最小化或总收益最大化,是IRP所要研究的重点。本文首先对选题背景和研究意义加以分析,并从生鲜产品运输和VMI两方面做出阐述,分析了国内外关于本文相关问题的研究现状。然后对生鲜产品的定义和分类、生鲜产品运输的问题和特点、VMI策略下的库存和运输相关问题以及主要算法进行了阐述说明,为本文打下了良好的理论基础。之后,根据生鲜产品运输的特征并考虑现实问题,建立了一个由供应商和零售商组成的二级供应链系统,并以消费者的随机需求为出发点,对供应商成本和零售商各项成本进行分析,最终将随机需求进行确定化处理,建立最终的数学模型。最后,通过算例进行实例分析,验证了模型和算法的有效性。
[Abstract]:With the development and progress of our country's economy and society, the quality of fresh products is becoming more and more demanding. As the most important product carrying unit in the whole supply chain, suppliers and retailers pursue the goal of how to reduce the consumption of fresh products. In a modern logistics system, suppliers and retailers should no longer "act in their own way" and consider only how to maximize their own interests, instead of reaching a consensus. As a whole to serve the society and satisfy the consumers, VMI (VMI) promotes the combination of suppliers and retailers. The inventory path problem (IRP) is the core problem in the process of implementing the VMI strategy. How to determine the quantity, time and travel path of restocking to each customer in a certain planning period, so as to minimize the total operating cost or maximize the total income of the system under certain constraints. First of all, this paper analyzes the background and significance of the topic, and expounds the transportation of fresh products and VMI. This paper analyzes the current situation of research on the related problems in this paper at home and abroad, and then explains the definition and classification of fresh products, the problems and characteristics of fresh product transportation and the inventory and transportation related problems under VMI strategy, as well as the main algorithms. After that, according to the characteristics of fresh product transportation and considering the practical problems, a two-stage supply chain system composed of suppliers and retailers is established, which takes the random demand of consumers as the starting point. The supplier cost and retailer cost are analyzed, and the stochastic demand is determined and the final mathematical model is established. Finally, the validity of the model and algorithm is verified by an example.
