Study On The Location Of Distribution Centers For Fresh Agricultural Products Under Discount Sales

Today,in the 21st century,fresh agricultural products are a must-have for people's lives and have a large market share.As a bridge between suppliers and demand points,the distribution center is self-evident about the importance of the circulation of fresh agricultural products.The freshness of fresh produce is negatively correlated with time and has a short life cycle.Therefore,the location decision of the fresh agricultural product distribution center must be very different from the location of the general logistics center.This paper takes the location of fresh agricultural product distribution center as the research topic of the thesis,which mainly includes the following contents:This paper analyzes and analyzes the relevant research results of the location of fresh agricultural products distribution center.According to the impact of the freshness of fresh produce on market demand,a functional relationship between market demand reduction and freshness was established.Considering that these reduced market demand can be sold through discount sales,resulting in damage costs.In addition,according to the distribution of fresh agricultural products,cold chain equipment is required,so the energy consumption cost of the cold chain equipment is considered in the model.Finally,the minimum cost model of storage cost,transportation cost,energy cost and total cost of goods based on discounted sales is established.The paper uses genetic algorithm to solve the model.In the algorithm execution,the reverse thinking method is adopted.Firstly,the supplier is assumed to be the demand point,and then the distribution center distributes all the demand points,and finally the solution of the model is obtained.This paper first uses a small example to explain the detailed construction process of the location of distribution centers for fresh agricultural products under discount sales,and then solves the case according to the site selection of Xi'an YH Supermarket Distribution Center.The paper solves the location model considering discount sales and not considering discount sales.By comparing the location results,it is concluded that the total cost of considering the discounted sales location is usually less than the total cost of not considering the discounted sales location.The result is different.Finally,the sensitivity analysis of the parameters of discount sales and the cost price of fresh agricultural products is verified,which verifies the feasibility and practicability of the research questions.
