在只知道需求分布部分信息条件下,研究三种碳排放政策(碳限额、碳税和碳权交易)下零部件再制造决策问题.首先根据销售收入、再制造成本、废弃处理成本、库存持有成本和缺货成本等构建总利润最大化的基本模型,并在此基础上分别扩展建立三种碳排放政策情形下包括碳排放成本的生产决策优化模型;然后将它转化为REVD(relative expected value distribu.tion)模型进行求解,在具有相同一阶矩、二阶矩的分布集合中,以最小化相对后悔值为鲁棒标准,寻找使得最坏分布下期望利润最大的最优再制造数;最后通过算例分析再制造率、有无碳排放政策以及三种不同碳排放政策的严惩程度对再制造数和总利润的影响,以期为再制造商和碳排放政策制定方在制定决策时提供帮助.
Remanufacturing decisions for dedicated part remanufacturers with limited demand distribution in- formation ( i. e. , the first moment and second moment) under three carbon emission policies ( carbon limita- tion, carbon tax and carbon trade policies) are studied in this paper. First, a basic model, which includes sales revenue, remanufacturing cost, disposal cost, inventory holding cost and shortage cost, but not carbon e- mission cost, is presented; Second, three different models considering carbon emission costs under three dif- ferent carbon emission policies are derived; Third, these models are solved by converting them into REVD ( relative expected value distribution) models, in which the optimal remanufacturing quantity which maximizes the minimum total profit is obtained by minimizing the relative regret value under the distribution set with the same first and second moment; Finally, the effects on the decisions of remanufacturing and the total profit of the carbon emission policy or the penalty degree are analyzed by an numerical example. These results can help dedicated part remanufacturers and policy makers to make reasonable decisions.
