研究了具有核心采购的混合制造/再制造系统在两种(高、低)质量条件下的采购和生产计划问题。我们将该问题建模为随机动态规划，推导出最优动态采购定价和生产策略，并分析了系统参数对采购价格和生产数量的影响。研究发现，再制造高质量和低质量核心与制造新产品之间的生产成本差异对最优生产和采购定价政策至关重要：高质量核心的采购价格在制造和再制造成本差异中增加，而低质量核心的采购价格在高质量和低质量核心之间的再制造成本差异中降低，制造和再制造成本差异增大；最优再制造/再制造政策遵循基于库存的模式，其特征是取决于这些成本差异的一些关键参数。
We study the acquisition and production planning problem for a hybrid manufacturing/remanufacturing system with core acquisition at two (high and low) quality conditions. We model the problem as a stochastic dynamic programming, derive the optimal dynamic acquisition pricing and production policy, and analyze the influences of system parameters on the acquisition prices and production quantities. The production cost differences among remanufacturing high- and low-quality cores and manufacturing new products are found to be critical for the optimal production and acquisition pricing policy: the acquisition price of high-quality cores is increasing in manufacturing and remanufacturing cost differences, while the acquisition price of low-quality cores is decreasing in the remanufacturing cost difference between high- and low-quality cores and increasing in manufacturing and remanufacturing cost differences; the optimal remanufacturing/manufacturing policy follows a base-on-stock pattern, which is characterized by some crucial parameters dependent on these cost differences.
