尽管再制造可以重新获得产品的附加价值，但是再制造产品和新产品具有一定的替代性，厂商在各期应该采用何种生产策略？本文选取单一制造厂商，首先讨论无偏好市场下两期再制造最优生产策略，建立厂商利润最大化的经济优化模型；然后给出了再制造成本节约临界值，以便厂商在不同的再制造成本区域内采取合适的价格和产量决策策略；进而将模型拓展。研究无限期的最优产量和定价策略。由于不同产品的再制造成本节约s的比例并不相同，本文通过优化所得的结论进行数据模拟，研究产品回收率和降级率对s‘的影响，s对厂商的产量、定价决策及利润的影响。进而分析降级率对产量和价格的影响，为厂商制定产品设计、生产和回收决策提供依据。

英文摘要：

Although remanufacturing may regain the additional value of products, remanufacturing products is an alternative choice to the new ones. What is the best production strategy for manufacturers in each period？ In this paper, we choose a single manufacturer for analysis. First of all, we discuss optimal remanufacturing production strategy in the two-period market without preference and present an economic optimization model, which the monopolist will choose to maximize the total profit. Then we identify the saving cost threshold. This helps the manufacturers decide how to make price and production strategies when the remanufacturing cost saving is in the specific district. Next, we extend the model to infinite period to characterize the optimal strategy. Since different kinds of products have different cost saving thresholds, we study how the recovery rate and quality degradation rate affect the cost saving threshold by numerical simulation of the economic optimization model. We also explore the effect of cost saving on the manufacturer＇s optimal pricing and output strategy and total profit. Further, we present the effect of degradation rate on production decision making, which will provide manufacturers with meaningful suggestions on product design, production decision and recycling policy.
