本文研究了考虑产品制造过程中环境因素的多产品供应商-买方供应链。我们假设买方收取的单位价格、单位广告费用和卖方的单位环境改善影响所售产品的需求。采用基于Stackelberg策略框架的非合作博弈模型，在供应商-领导者模型和买家-领导者模型两种权力情景下对供应商和买家之间的关系进行建模。采用双层规划方法确定最优销售价格、广告支出、批发价格、供应商的环境改善和供应商和买方的订购政策。然后，提出了一种改进的差分进化算法来求解模型。本文进行了数值实验，包括对一些关键参数的敏感性分析，评估了模型的有效性，并比较了不同模型的结果。获得并解释了一些研究结果。
This paper focuses on a multi-product vendor-buyer supply chain considering environmental factors in the product manufacturing process. We assume that the unit price charged by the buyer, the unit advertising expenditure and the vendor’s unit environmental improvement influence the demand of the product being sold. The relationship between the vendor and the buyer is modeled by a non-cooperative game based on Stackelberg strategy framework under two power scenarios including vendor-leader model and buyer-leader model. A bi-level programming approach is applied to determine the optimal selling prices, advertising expenditures, wholesale prices, vendor’s environmental improvements and ordering policies of the vendor and the buyer. Then, a modified differential evolution algorithm is proposed for solving the models. Numerical experiments carried out in this paper, including sensitivity analysis for some key parameters, evaluate the effectiveness of the models and compare the results between the different models considered. Several research findings have been obtained and explained.
