在再制造生产率和市场需求不确定情况下,研究考虑了资金时间价值的企业制造/再制造生产决策优化。结合应收账款回收期,建立了考虑资金时间价值的制造/再制造生产决策模型,通过两阶段随机过程分析得到了回收品最优采购量和最大利润。算例分析表明:阶段一的期望利润随着回收品采购量的增加先增加后减少;阶段二的期望利润随着计划产量的增加呈先增加后减少趋势;随着贴现率的增加,在每个贴现率下的利润曲线随着应收账款回收期的增加,利润下降速度加快。
In the case of uncertainty of remanufacturing productivity and market demand, the optimization of manufacturing decision-making in manufacturing / remanufacturing considering the time value of capital is studied. Combined with the payback period of receivables, a manufacturing / remanufacturing decision-making model considering the time value of funds was established. The optimal purchasing amount and profit of the recycled products were obtained through two-stage stochastic process analysis. The case study shows that the expected profit of stage one increases first and then decreases with the increase of the purchase amount of recovery goods. The expected profit of stage two increases first and then decreases with the increase of planned output. With the increase of discount rate, The profit curve under the discount rate With the recovery of the receivables, the profit declines faster.
