To determine the optimal lot sizes for the manufacturing of new items and the remanufacturing of returned 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.
