【摘要】 随着社会的发展、生产力的进步、生活水平的不断提高,社会餐饮业需求得到了高速增长,餐饮市场的竞争也日趋激烈。对餐饮业的经营管理者来说,在激烈的市场竞争环境下,在经营活动中供应链管理的作用越来越大,而库存管理作为供应链中的重要环节,如何制定最优的库存策略已经成为经营者必须解决的问题。本文将对餐饮企业重要原材料之一的鲜活水产品库存管理策略进行研究。本文首先对餐饮企业水产品库存管理研究的背景、国内外研究现状以及研究的意义进行了阐述。并结合库存理论对水产品库存管理的特点的进行了分析。选取了成本高、利润值大的深海龙虾、淡水蟹两个品种,通过对销售历史数据的分析,得到了常年型水产品和季节性水产品的不同销售特征,通过软件拟合的方法得到了各自的需求分布函数。通过每天订货的报童模型、按保质期为周期的报童模型和EOQ模型三种方法对餐饮企业水产品库存管理进行了模型的建立,分别求解出最优的订货策略,根据历史销售数据进行了验证和比较,得出按每天订货的报童模型求得的订货策略为餐饮企业水产品库存管理的较优订货策略。最后对全文进行了总结,并对未来的研究方向和相关领域进行了展望。更多还原

【Abstract】 With the increasing economic development of Society and the improvement of the living level, the demand of catering trade has been raising and developing in a high speed. As a result, the total investment in catering trade has been augmenting, as well as the severe competition for the market. Therefore, it is essential to enhance the functionality of the supply chain during the management of the enterprise, where inventory management identifies itself as a pivot among the supply chain. The decision-makers are always trying to find an optimal solution of the inventory to get a more cost-effective investment. The present paper studies how to make a better strategy for the inventory management of fresh aquatic products, which are one of the most important raw materials in the catering enterprise.This paper starts by discussing the background of the research, the current situation of such kind of study over the world, and the purpose of this research. Then, an inventory theory is used to analyze the characteristics of inventory management of the aquatic products. Two examples, deep sea lobster and fresh crab, are selected to demonstrate the analysis. The properties of non-seasonal and seasonal aquatic products are obtained by studying the historic data of the sales. Then, the distribution functions of the demand of these two different items are generated by interpolating these historic data. After that, models for the inventory management are built, solved by using three methods, which are Newsboy Model (order every day), Newsboy Model (cycle of the quality guarantee period), and Economic Order Quantity (EOQ). Optimal inventory levels calculated from these methods are verified and compared based on historic sales data. Finally the solution got from the Newsboy Model with a daily order is approved to be the optimal solution.At the end of this paper, a conclusion is drawn, and the future work of the research is discussed.更多还原
