摘　　要：零件的回收再制造并再销对资源节约及减少环境负担具有重要意义。本文的再制造供应链由采购、运输、仓储、制造活动组成,在市场需求与可再制造零件数量双重不确定情景下,构建包含回收件的采购批量、再制造生产批量的决策模型,探索可能存在的最优批量和成本水平以及双重不确定性对生产批量和采购批量的影响。研究表明:分别实现年环境成本、年经济成本、年总成本最低时,均存在唯一最优生产批量和采购批量;市场需求与可再制造零件数量的双重不确定性水平会对最优解产生不同影响,而可再制造零件或新零件处于散存和制成品两种制备阶段的相关成本变化,将会决定企业再制造的不同批量策略。The recycling,remanufacturing and reselling of parts is of great significance for the resource conservation and reduction of environmental burden.For example,the first batch of 14 remanufacturing pilot enterprises announced by the National Development and Reform Commission,such as WEICHAI Power(Weifang)and Sino-Trunk,have started to calculate the economic cost of the whole remanufacturing supply chain of waste engines and other parts and arranged remanufacturing production in combination with demand orders.Meanwhile,in August 2022,the National Development and Reform Commission,the National Bureau of Statistics and the Ministry of Ecology and Environment jointly issued the Implementation Plan on Accelerating the Establishment of a Unified and Standardized Statistical Accounting System for Carbon Emissions,proposing that a unified and standardized statistical accounting system for carbon emissions would be initially established by 2023.Therefore,this study provides decision-making reference for enterprises to formulate remanufacturing production batch strategy and procurement batch strategy under double uncertainty.In this paper,the remanufacturing supply chain consists of procurement,transportation,storage and manufacturing activities.Considering the uncertainty of the annual demand quantity of the end market and the uncertainty of the quantity of remanufactured parts in the recycling market,and taking each production batch and purchase batch in the remanufacturing process as the decision variables,a baseline model is established for the annual environmental cost,annual economic costs,and annual total costs of the entire remanufacturing supply chain system.The following problems are studied:(1)By solving the model,the existence of the optimal production batch and purchase batch is discussed respectively when the annual environmental cost,annual economic cost and annual total cost are the lowest.(2)The expression of the optimal production batch and purchase batch is calculated,and the optimal production decision of
