回收再制造能够降低生产成本,节约原材料,减少环境污染,但是管理更加复杂,企业需要同时优化回收与生产两方面的决策。该文通过对需求不确定环境下的再制造企业生产回收联合优化问题进行建模,从需求分布和再制造成本、回收成本等分析出发,运用非线性优化的方法,求解了最优回收比例与最优总产量决策。结论表明,在需求波动不大的情况下,再制造带来的变动成本节约越明显,再制造所需投资越少,则再制造比例越高且总产量越高;强制再制造比例政策随着生产成本结构的不同会带来再制造生产的扩张或者萎缩。研究结果为再制造厂商根据需求及成本结构合理制定生产回收决策以及政府根据生产成本特点制定再制造产业政策提供了有益的管理启示。
Remanufacturing can reduce production costs, conserve raw materials, reduce environmental pollution, but management is more complex and companies need to optimize both recovery and production decisions. Based on the analysis of the demand distribution, remanufacturing cost and recovery cost, the non-linear optimization method is used to solve the optimal recovery proportion and Optimal total output decision. The conclusion shows that under the condition of small fluctuation of demand, the cost saving of remanufacturing becomes more obvious, the less remanufacturing requires less investment, the higher the remanufacturing proportion and the higher the total output. The compulsory remanufacturing proportion policy The differences in the structure of production costs will lead to the expansion or contraction of remanufactured production. The results provide a useful management enlightenment for remanufacturers to reasonably formulate the production recovery decision according to the demand and cost structure and the government formulates the remanufacturing industry policy according to the characteristics of production cost.
