【摘要】：随着信息技术和市场经济的不断发展,企业之间竞争日益激烈.企业间的单体竞争已逐步变成供应链与供应链之间的竞争,供应链协调已成为企业提高竞争力的关键.另一方面,由于技术或人为等原因,生产的产品的质量是非完美的,一部分是合格品,另一部分是次品.一般只有合格品才能用于销售,次品只能通过重新加工、折价出售或者直接丢弃等方式处理,这会带来一定的经济损失.因此,本文研究次品率可控的产品的供应链协调问题具有重要的现实意义.主要内容包括： (1)研究了基于信用支付和成本改善的供应链协调问题.假设供应商生产非完美质量的产品,其中次品率可以通过投资改善.采用信用支付和成本改善协调机制,建立了优化供应商成本的模型.最后,数值例子表明零售商的成本改变量在一定范围内取值时,供应链才能够得到协调. (2)研究了基于价格折扣和利润分配的供应链协调问题.采用两种协调机制,建立了相应的协调模型.通过仿真实验,分析部分参数变化对系统利润的影响. (3)研究了基于收益共享的供应链协调问题.供应商降低产品的批发价格,零售商将其一定的比例的销售收入还给供应商,建立了相应的协调模型,通过分析模型,给出模型解的理论结果.最后,通过数值例子分析了部分参数变化对供应商、零售商和供应链利润的影响.
[Abstract]:With the continuous development of information technology and market economy, the competition between enterprises is becoming increasingly fierce. The single competition among enterprises has gradually become the competition between supply chain and supply chain, and supply chain coordination has become the key for enterprises to improve their competitiveness. On the other hand, due to technical or artificial reasons, the quality of the product is not perfect, one is qualified, the other is inferior. Generally, only qualified products can be used for sale, and defective products can only be reprocessed, sold at a discount or discarded directly, which will bring about certain economic losses. Therefore, it is of great practical significance to study the supply chain coordination of defective products with controllable rate. The main contents are as follows: (1) supply chain coordination based on credit payment and cost improvement is studied. Suppose the supplier produces a product of imperfect quality, in which the defective rate can be improved by investment. Using credit payment and cost improvement coordination mechanism, the model of optimizing supplier cost is established. Finally, numerical examples show that the supply chain can only be coordinated when the retailer's cost change is within a certain range. (2) the supply chain coordination problem based on price discount and profit distribution is studied. Two coordination mechanisms are used to establish the corresponding coordination model. Through simulation experiments, the effects of partial parameter changes on system profits are analyzed. (3) the problem of supply chain coordination based on revenue-sharing is studied. The supplier reduces the wholesale price of the product, and the retailer returns a certain proportion of the sales income to the supplier. The corresponding coordination model is established, and the theoretical results of the model solution are given through the analysis of the model. Finally, a numerical example is given to analyze the effect of some parameter changes on the profit of suppliers, retailers and supply chain.
