摘要
在模糊需求下建立了包含碳排放单价不变和可变的最优订货批量模型,根据库存成本控制模型求解最佳订货点和最优订购批量,使得库存成本最小。算例结果表明,在碳排放单价随着碳排放量发生变化时,库存成本会不断上升。因此企业更需要重视碳排放量给企业库存成本带来的影响。
The optimal order quantity model under fuzzy demand is established with variable or invariable price of carbon emission.According to the inventory cost control model,the optimal reorder point and the optimal order quantity which make the minimum inventory cost are calculated.Numerical examples show that the unit price of carbon emission changing leads to the total cost of inventory rise.Therefore it＇s urgent that the enterprise should pay more attention to carbon emission quantity that influence the inventory cost.
