【摘要】：随着国内外的多渠道销售、集装箱运输以及互联网的发展,网上购物越来越受到消费者的青睐,网购供应链也随之而生。虽然网购有诸多优势,但也存在许多问题。如网购消费者不能亲身检查、感受商品,导致了网上购物的高退换货率;商品在运送过程中的损坏等等。本文以网购供应链为研究对象,运用博弈论及变分不等式、最优化等相关理论,研究了竞争环境下网购供应链均衡模型,并对各层决策者进行行为分析,得到竞争均衡解。在传统供应链的基础上,引入新的决策者—运输商,形成网购供应链。建立了基于质量和价格竞争的多层网购供应链超网络均衡模型,该模型关注多个原材料供应商(电商、快递商)凭借价格和质量进行内部竞争的问题。原材料供应商(电商、快递商)的利润不仅取决于自身的价格、质量而且取决于竞争者的价格、质量。利用数值算例进行仿真,并通过得到的相应结果,说明模型的普遍性与可行性,进一步给出提高供应链效率的建议。针对网购过程中的高退换货率,建立了竞争条件下基于退换货的闭环网购供应链动态均衡模型。首先,考虑消费者的退换货行为将网购供应链推闭环的广为网购供应链,并分析不同的换货率对购买量和总的退换货量的影响。其次,通过正弦函数说明网购供应链的市场需求随时间呈季节性变化。再次,将运输商的运输速度作为竞争的一个重要因素进行研究,并分析不同等待时间成本系数对购买量、运输量的影响。最后,通过数值算例说明了模型的正确性与合理性,并给出相应的经济解释。
[Abstract]:With the development of domestic and foreign multi-channel sales, container transportation and Internet, online shopping is becoming more and more popular among consumers, and the supply chain of online shopping is also born. Although online shopping has many advantages. But there are many problems, such as online shopping consumers can not personally check, feel the goods, resulting in online shopping high rate of return and exchange; This paper takes the online purchase supply chain as the research object, applies the game theory, variational inequality, optimization and other relevant theories to study the supply chain equilibrium model in the competitive environment. Based on the analysis of the behavior of the decision-makers at different levels, the competitive equilibrium solution is obtained. Based on the traditional supply chain, a new decision-maker, the transporter, is introduced. A multi-layer supply chain super-network equilibrium model based on quality and price competition is established, which focuses on a number of raw material suppliers (e-commerce). The profit of suppliers of raw materials (ecommerce, courier) depends not only on their own price, but also on the price of competitors. Quality. The numerical example is used to simulate, and the corresponding results are obtained to illustrate the universality and feasibility of the model, and further give some suggestions to improve the efficiency of supply chain, aiming at the high rate of return and exchange in the process of online purchase. The dynamic equilibrium model of closed-loop online purchase supply chain based on return and exchange is established. Firstly, considering the behavior of consumers, the online purchase supply chain is pushed to a wide range of online purchase supply chain. And analyze the different exchange rate on the purchase volume and the total return and exchange volume. Secondly, through the sine function to explain that the market demand of online shopping supply chain changes seasonally with time. Again. This paper studies the transportation speed of the carrier as an important factor of competition, and analyzes the influence of the cost coefficient of different waiting time on the purchase quantity and the transportation volume. A numerical example is given to illustrate the correctness and rationality of the model, and the corresponding economic explanation is given.
