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。
Although remanufacturing can regain the added value of products, remanufacturing products and new products have some substitutability. What kind of production strategy should manufacturers adopt in each period? In this paper, a single manufacturer is selected, The optimal manufacturing strategy and the optimal economic profit model are established. Then, the critical value of remanufacturing cost is given so that the manufacturer can adopt appropriate price and output decision strategies in different remanufacturing costs. Then the model is extended , Study the optimal yield and pricing strategy indefinitely. As the cost-saving ratio of remanufacturing cost varies from product to product, this paper simulates the data through the optimization results to study the effect of product recovery rate and degradation rate on s * and the influence of s on firm’s output, pricing decision and profit , And then analyze the impact of the downgrade rate on production and price to provide the basis for manufacturers to make decisions on product design, production and recycling.
