【摘要】：蔬菜是农产品的重要组成部分,为人类社会的生存提供了必不可少的营养物质。根据研究显示,我国的生鲜蔬菜在配送中的流通过程如采摘,运输,储存,配送等环节的损失率在25%-30%,这造成的经济损失近1000亿。而在美国等发达国家的蔬菜供应链采用冷链管理,配送过程损失率仅为1%-2%。相对于国外,我国蔬菜供应链的效率还有进一步改善和优化的空间。本文构建了一条由蔬菜生产者,配送中心,终端销售中心,消费者和回收处理中心组成的蔬菜供应链体系,通过显性和隐性成本两方面对供应链所涉及到的成本进行建模并且分析。对于显性成本而言,包含正向供应链体系中的流通成本和逆向供应链回收体系中的环境成本;然而在蔬菜供应链运行的背后个体之间却离不开博弈,因此本文在隐性成本方面主要研究了蔬菜供应链背后的关系成本。通过对模型的求解可以得出成本模型的理论最优解。最后构建了一个算例,通过对影响蔬菜供应链各个主体的相关系数进行赋值,对比了蔬菜供应链未整合前和整合集成后的总成本,得出了只要博弈双方能按照最优收益分配系数来分配通过合作所获得的收益,供应链的成本将比未整合时的成本要低。因此,可以通过确定蔬菜供应链的最优分配系数来对供应链的成本进行优化。
[Abstract]:Vegetables are an important part of agricultural products and provide essential nutrients for the survival of human society. According to the research, the circulation process of fresh vegetables in our country, such as picking, transportation, storage, distribution and other links, the loss rate of 25-30, which caused economic losses of nearly 100 billion. In the developed countries, such as the United States, cold chain management is adopted, and the loss rate of distribution process is only 1-2. Compared with foreign countries, there is room for further improvement and optimization of the efficiency of Chinese vegetable supply chain. This paper constructs a vegetable supply chain system composed of vegetable producers, distribution centers, terminal sales centers, consumers and recycling centers. The cost involved in supply chain is modeled and analyzed by explicit and implicit cost. For the explicit cost, it includes the circulation cost in the forward supply chain system and the environmental cost in the reverse supply chain recovery system. However, the individuals behind the vegetable supply chain are inseparable from the game, so this paper mainly studies the relationship cost behind the vegetable supply chain in the aspect of recessive cost. The theoretical optimal solution of the cost model can be obtained by solving the model. Finally, an example is constructed to compare the total cost of the vegetable supply chain before and after integration by assigning the correlation coefficients that affect the main body of the vegetable supply chain. It is concluded that the cost of the supply chain will be lower than that of the unintegrated supply chain as long as the two players can distribute the benefits through cooperation according to the optimal income distribution coefficient. Therefore, the cost of the supply chain can be optimized by determining the optimal distribution coefficient of the vegetable supply chain.
