基于制造商行为偏好的零件质量升级努力与定价策略研究

为研究供应商与存在行为偏好的制造商组成的二级供应链中质量升级努力投入与定价问题，根据均值−方差法和FS公平理论构建模型，采用Stackelberg博弈的方法，分析最终产品质量水平、零件质量水平、零件质量升级水平及制造商的行为偏好对供应链双方决策和效用的影响，并通过数值仿真验证。研究发现，供应链双方效用、零件售价、零件质量升级努力及订货批量与零件质量升级水平成正相关的同时，受其影响与最终产品质量水平呈不同变化趋势；零件售价受市场环境影响与零件质量水平呈不同变化趋势，供应链双方效用、零件质量升级努力及订货批量与零件质量水平负相关；订货批量、零件质量升级努力、零件售价与制造商的风险规避程度正相关，与制造商的公平偏好程度负相关。

Research on Part Quality Upgrade Efforts and Pricing Strategy Based on Manufacturer's Behavior Preference

In order to study the effort input of quality upgrade and pricing in the secondary supply chain composed of suppliers and manufacturers with behavioral preferences, a model was established based on mean-variance method and FS fairness theory. Using the method of Stackelberg game, the impact of the quality level of the final products and parts, the quality upgrade level of the parts and manufacturer's behavior preference on the decision-making and utility of both sides of the supply chain was analyzed, and verified by numerical simulation. The study found that while the utility of both sides of the supply chain, the price of parts, the efforts to upgrade the quality of parts, and the order quantity are positively correlated with the level of quality upgrade of parts, they are affected by the level of quality upgrade of parts and show different trends from the quality of final products. Furthermore, the price of parts is affected by the market environment and the quality of parts shows different trends. The utility of both sides of the supply chain, the efforts to upgrade the quality of parts, and the order quantity are negatively related to the quality of parts. The order quantity, the efforts to upgrade the quality of parts, and the price of parts are positively related to the manufacturer's risk aversion, and negatively related to the manufacturer's fairness preference.
