摘　　要：为了确定制造/再制造混合系统的最优生产批量,假定需求率和回收率是连续、确定的,以单位时间内新产品和再制造产品的订购费以及回收件和可用件的存储费之和最小为目标,建立了新产品制造和回收件再制造的最优批量模型.为保证批次是正整数,给出了批量计算结果的简单修正方法.该模型不仅适用于再制造生产率有限和无限的情形,而且适用于制造生产率有限和无限的情形.算例结果验证了该模型的有效性.To determine the optimal lot sizes for the manufacturing of new items and the remanufacturing of tetrned items in a hybrid manufacturing/remanufacturing system, two models were established on the basis of the assumption that the demand rate and the return rate are continuous and deterministic. The objective in these models is to minimize the total cost per time unit for ordering remanufacturing and manufacturing lots and holding returned and new/remanufactured items in stock. In addition, simple modifications of calculated lot sizes were proposed to make the number of lot sizes be a positive integer. The proposed models can be used to the conditions whether remanufacturing and manufacturing rates are finite or infinite. The validity of the models has been proved with an example.
