Study On Vegetable Supply Chain Management Based On Cost Models

Vegetables are an important part of agricultural products,but also essential for urban and rural residents,which provide an essential nutrient of the necessities of life for the survival of human society.The quality and safety of vegetables play a vital role in the daily life of human beings.According to a research report,the rate of China's wasted fresh vegetables in the distribution process such as picking,transportation,storage,distribution and other aspects,is between 25%-30%,which caused economic losses of nearly 100 billion RMB.In the United States and other developed countries,the vegetables' cold chain management has been used and the loss rate of distribution process is only 1%-2%.Compared with foreign countries,the efficiency of China's vegetable supply chain needs to be further improved and optimized.In this paper,a vegetable supply chain system is established,which consists of vegetable producer,distribution center,terminal sales center,consumer and recycling center,and the cost of the system is modeled and analyzed.In the process of establishment of the cost model,two aspects of the dominant cost and recessive cost of the supply chain are mainly considered.In terms of dominant costs,environmental costs in the reverse supply chain recovery systems and circulation costs in the forward supply chain are included;however,in the operation of the vegetable supply chain,it cannot be separated from the back of the game between the individuals.Therefore,in this paper the relationship cost of the vegetable supply chain is mainly studied.Finally a numerical example is offered in which different influence coefficients are assigned to different values.By comparing the total cost of the vegetable supply chain before and after the integration,it is concluded that the after-integration cost is lower than the before-integration cost when the extra profits are allocated among the supply chain members according to the optimal partition coefficient.Therefore the total cost of vegetable supply chain can be optimized by determining the most suitable profit partition coefficient.
