| Considering the requirements of the sustainable development with greenpurchasing can take into account the current economic development and long-termsocial development. Suppliers’ selection is the first step in achieving green purchasing,and it is the most critical step. Suppliers are in the upstream of the green supply chain,it passed through the supply chain in the protection of the environment and achieveeconomic benefits by the various segments of the downstream. So, in the green supplychain management, the establishment of a scientific and effective supplier evaluationand selection system and model has important theoretical and practical value.First, the literature took full account of the new requirements of the greensupply chain for suppliers on the basis of finishing review and summarized relatedindicators of factors that can affect the evaluation of suppliers. The paper built a greenprocurement supplier evaluation system; Second, the use of the combination of roughset and neural network determined the weight of each index value in the evaluationindex system: the use of rough set theory established supplier evaluation index systemand eliminated redundant indicators; then this paper put reduction evaluation data asthe input of the neural network to improve the clarity of the data and reduce the sizeof the artificial neural network computing; Finally, the paper used artificial neuralnetworks for the evaluation and selection of suppliers.After the selection of suppliers, the paper started from the point of view ofoption pricing, buyers and sellers in the case of option pricing market-oriented supplychain coordination to optimize the decision-making model in the context of the greensupply chain; then, the paper used the internal members of the supply chain’ profitoptimization mechanism model to calculate the optimal pricing strategy and theoptimal purchasing decisions to achieve the overall profit of the supply chainoptimization suppliers and retailers, and used MATLAB simulation analysis of theresults of the model validation analysis.With specific examples and empiricalanalysis of the two models built, and obtained relevant results. |
