碳排放折扣下经济订货批量研究

Study on Economic Order Quantity under Carbon Emission Discount

摘要: 我国是能源消耗大国，每年的二氧化碳排放量巨大，而库存作为企业供应链管理的关键环节，对其碳排放的研究至关重要。在生产运作过程中，批量折扣是常见的事情。在规模经济效应下，大批量的生产不仅会降低产品的单位成本，而且使产品的单位排放递减；同时在碳排放约束下，传统的经济订货批量(EOQ)库存模型最优解也会发生改变，本文在价格折扣EOQ模型的基础上考虑碳排放约束和“折扣”，研究企业最优订货批量，使企业达到减排的目标。

Abstract: China is a major energy-consuming country with huge annual CO2 emissions, and the study of car-bon emissions from inventory, a key part of corporate supply chain management, is crucial. In production operations, volume discounts are common. Under the effect of economy of scale, the production of large lots will not only reduce the unit cost of the product, but also make the unit emission of the product decreasing; meanwhile, under the carbon emission constraint, the optimal solution of the traditional economic order quantity (EOQ) inventory model will be changed, and this paper considers the carbon emission constraint and “discount” on the basis of the price discount EOQ model, and studies the optimal order quantity of enterprises to make them achieve the goal of emission reduction.
