【摘要】：库存控制是供应链管理的主要内容之一，科学合理的库存策略有助于降低供应链成本、减少资源的浪费、提高供应链上下游的服务水平；食品是人类生活中最重要的物资之一，每天的库存周转量都十分巨大，因此对供应链环境下的食品库存进行相关理论研究有着十分重要的意义。传统的库存理论并不适用于具有“易变质”特性的食品，食品的库存减少主要有需求和变质两种因素。本文针对食品“易变质”的特性进行分析，重点研究了供应链中生产和销售两个环节，主要从两种情况入手针对食品的产成品库存进行了研究。首先研究了生产环节的食品库存控制理论。生产商作为食品的供应者，本身拥有生产能力，其库存的变化同时与生产、需求和变质相关。本文在允许缺货的情况下拓展了EOQ模型，分别考虑了部分短缺量拖后和库存水平影响需求这两种情况，，并在对库存变化情况做出充分分析的基础上给出了食品库存控制模型，为不同情况下食品生产商如何选择产成品的库存策略提供了理论依据。然后研究了销售环节的食品库存控制理论，零售商的食品库存变化主要与消费者需求和食品变质相关。因此在面临着同样允许缺货的情况时，零售商和生产商的库存策略并不相同。最后本文给出了以消费者需求为中心的供应链环境下生产-销售环节食品库存控制模型。当生产商的生产策略随销售商的库存策略变化而变化时，分别考虑部分短缺量拖后和库存水平影响需求两种情况，建立了供应链环境下的生产-销售环节食品库存模型，并利用MATLAB软件对给出的算例进行求解，验证了模型的正确性。对供应链上的主要参与者如何选择库存策略有一定的借鉴意义。
[Abstract]:Inventory control is one of the main contents of supply chain management. A scientific and reasonable inventory strategy is helpful to reduce the cost of supply chain, reduce the waste of resources, improve the service level of upstream and downstream of supply chain, and food is one of the most important materials in human life. The daily inventory turnover is very large, so it is very important to study the food inventory in the supply chain environment. The traditional inventory theory is not suitable for food with "perishable" characteristics. There are two main factors in the reduction of food stock: demand and deterioration. This paper analyzes the characteristics of food "perishable". This paper focuses on the production and sales in the supply chain, mainly from the two situations to study the inventory of finished products of food. First of all, the theory of food inventory control in production link is studied. The producer, as the supplier of food, has its own production capacity, and the change of its stock is at the same time with the production. This paper extends the EOQ model under the condition of allowing shortage, and considers the delayed partial shortage and the effect of inventory level on demand. The food inventory control model is given based on the analysis of the inventory change, which provides a theoretical basis for food producers to choose the inventory strategy of finished products under different conditions. Then it studies the food inventory control theory in the sales link. The change of the retailer's food inventory is mainly related to the consumer demand and food deterioration. Retailers and manufacturers have different inventory strategies. Finally, this paper gives the food inventory control model of production-sales link in the supply chain environment with consumer demand as the center. When the manufacturer's production strategy changes with the seller's inventory strategy, Considering the delay of partial shortage and the influence of inventory level on demand, the food inventory model of production-sale link in supply chain environment is established, and the example is solved by MATLAB software. The correctness of the model is verified, and it is useful for the main participants in the supply chain to choose inventory strategy.
