摘要
通过分析采购流程中各环节所产生的成本,在多个供应商、多个库存点的情况下,协调采购数量使采购成本最小化,同时使采购流程中的运输环节所产生的碳排放最小化,建立了一个多目标函数的数学模型,通过GUROBI工具求解,最后用实例证明了该模型的有效性。
In this paper, through analyzing the cost generated in the various links in the purchasing process and in the event of multiple suppliers and inventory spots, we coordinated the purchasing quantity to minimize purchasing cost as well as the carbon emissions in the transportation link, established a multi-objective function model and used the GUROBI tool to solve the model and at the end proved the validity of the model through an empirical case.
