【摘要】：果蔬品具有保鲜周期短、容易腐烂变质、不宜长时间储存等特征。商品必须在有限时间内售出,否则将发生损坏、质变、过期,使变质成本成为沉重的负担,影响商品的销售价值和销售量,给企业带来一定的经济损失。果蔬品由于季节、价格、销售策略等因素会引起需求量的波动。因此,在需求变化的前提下,研究果蔬品的库存问题具有一定的理论和现实意义。以往这类易腐品的库存模型研究是在需求确定等各种假设条件下,建立了易腐品库存系统最优控制模型；或者直接运用传统的经济订货批量模型,来确定库存成本和订货成本的总和最小的订货批量,但与实际情况有一定差距。针对以往研究的不足,本文基于需求弹性可变的情形下,结合果蔬品的易变质特性在允许缺货和不允许缺货两种情况下对库存策略进行研究,为订货商的果蔬品库存管理提供决策依据。论文的主要研究工作和创新性成果如下：结合果蔬品易变质的特点和消费者的需求状况,重点分析需求是价格弹性函数的基础上,在不允许缺货情况下,建立果蔬品的库存模型,并求得最大库存量、存储成本、变质成本的计算公式,从而确定最优订货周期和订货量。通过实例对变质率和顾客规模等重要参数进行灵敏度分析,得到最终结论,验证了模型的实用性和有效性。结合实例分析中各参数的影响程度,提出相应的改进策略,对企业的库存成本优化起到一定指导和借鉴意义,为企业管理人员有效管理库存提供理论依据。结合果蔬品易变质的特点和消费者的需求状况,重点分析需求是价格弹性函数的基础上,在允许缺货情况下,引入了丢单系数建立库存控制模型,并求解该模型。求得存储成本、变质成本、缺货成本、丢单成本的计算公式,从而确定最优订货周期和订货量。通过实例对服务水平和丢单系数等重要参数进行灵敏度分析,得到最终结论,验证了模型的实用性和有效性。结合实例分析中订货商库存管理中出现的问题,提出相应的改进策略,对企业的库存成本优化起到一定指导和借鉴意义。
[Abstract]:Fruits and vegetables have the characteristics of short preservation period, easy to rot and deterioration, not suitable for long-term storage. The goods must be sold in a limited time, otherwise it will be damaged, changed and expired, making the cost of deterioration become a heavy burden. Affect the sales value and sales of goods, bring certain economic losses to enterprises. Fruit and vegetable products due to season, price, sales strategy and other factors will cause demand fluctuations. Therefore, under the premise of changing demand. It is of great theoretical and practical significance to study the inventory problem of fruits and vegetables. In the past, the inventory model of perishable products was established under various assumptions such as demand determination and so on, and the optimal control model of perishable inventory system was established. Or directly use the traditional economic order batch model to determine the inventory cost and order cost the sum of the smallest order batch, but there is a certain gap with the actual situation. Based on the variable demand elasticity, combined with the perishable characteristics of fruits and vegetables, the inventory strategy is studied in the case of permitted shortage and no shortage. The main research work and innovative results of this paper are as follows: combined with the perishable characteristics of fruit and vegetable products and consumer demand. Based on the price elasticity function, the inventory model of fruits and vegetables is established, and the calculation formulas of maximum inventory, storage cost and deterioration cost are obtained. In order to determine the optimal order period and order volume, through the example of the deterioration rate and customer size and other important parameters of sensitivity analysis, the final conclusion is obtained. The practicability and validity of the model are verified. Combined with the influence degree of the parameters in the analysis of examples, the corresponding improvement strategy is put forward, which plays a certain guiding and referential significance to the optimization of the inventory cost of the enterprise. It provides the theoretical basis for the enterprise managers to manage inventory effectively. Combined with the characteristics of the perishable fruit and vegetable products and the consumers' demand, the emphasis is on the basis of the price elasticity function, under the condition of allowing the stock to be out of stock. The inventory control model is established by introducing the loss coefficient, and the model is solved. The calculation formulas of storage cost, deterioration cost, out-of-stock cost and loss cost are obtained. In order to determine the optimal order period and order volume. Through the analysis of the service level and lost order coefficient and other important parameters sensitivity analysis, the final conclusion is obtained. The practicability and validity of the model are verified. According to the problems in the inventory management of orderists, the corresponding improvement strategies are put forward, which plays a certain guiding and referential significance to the optimization of the inventory cost of enterprises.
