产品质量和WTP差异下的制造/再制造生产决策

在需求与价格、质量相关的假设下, 提出再制造产品的3 种生产模式, 给出最优生产决策. 研究结果表明, 随着再制造产品支付意愿(WTP) 的提高, 第2 阶段新产品产量都将下降, 再制造产品和第1 阶段新产品产量在Model O和Model OI 模式下上升, 在Model I 模式下不变; 产品质量的上升会使所有产品的产量都下降, 导致原设备生产商(OEM) 的收益下降, 而独立的再制造商(IR) 的收益在一定范围内上升, 但其获利所需最低WTP值也将上升. 数值仿真验证了各参数对生产决策及利润的影响.

Manufacturing/remanufacturing decision based on product quality and WTP differentiation

Three kinds of production models of remanufactured products are established based on the price-dependent and quality-dependent demand. The optimal production decisions of the three models are given. The results show that, with the improvement of willing to pay(WTP) for the remanufactured products, the production yield of the new product in second stage of all systems will decrease, and the production yield of the new product in the first stage and remanufactured product in the second stage will increase under Model O and Model OI, and will not change under Model I.With the improvement of quality grade, the production yield of new products and remanufactured products of all systems will decrease. It is also found that with the improvement of product’s quality grade, the original equipment manufacturer(OEM) will lose some profit, the independent remanufacturer(IR)’s profit can be improved in some certain, but the required minimum WTP for its profit will rise. The numerical simulation verifies the effects of the parameters on the production decision and profits.
