碳排放是导致全球气候变暖的主要因素之一。随着全球气候变暖问题的日益严重,企业面临如何有效整体减排的难题。针对供应商这一间接碳排放的主要来源,碳排放已经成为企业选择供应商的要素之一。本文构建随机需求下考虑碳排放因素的单个企业面对多个供应商,且受供应商产能约束的非线性混合整数规划模型,并结合模型自身特点设计了相应算法。最后,通过数值实验分析碳排放价格及运输工具的变化对选择供应商的影响。
Carbon emission is one of the major factors of global warming. With the increasing seriousness of global warming, the enterprise faces the problem of emission reduction. Because supplier is the major source of the indirect carbon emission, carbon emission has becoming one of the key criteria of supplier selection. Under stochastic demand and considering carbon emission, the model which single manufacturer who selects multi-suppliers; and these suppliers has the restriction on the production capacity is constructed. Then the algorithm which combining the characters of the model is designed. In the end, supplier selection effected by the price of carbon emission and transportation instrument in the numerical experimentation is analysed.
