Abstract: Aiming at the used products which took whole remanufacturing as main use patterns in remanufacturing system, the unconstrained mixed-integer-programming collection model with single period was proposed by considering the factors such as used product's quality and the reservation collection price. The optimal collection policy of model which included collection price, collection quantity and remanufacturing cost threshold was obtained to gain maximum expected revenue. The effect of uesd products'collection quantity, collection quality, waste disposal cost and reservation collection price on optimal collection policy was analyzed by numerical simulation. The results showed that the collection price and quantity could be increased with stable collection source, and the remanufacturer's expected profit could be decreased with unit disposal cost and increased with the used product quality. Furthermore, the remanufacturer had more willingness to remanufacture but had little incentive to increase collection price for higher collection quantity based on the merely economic benefits.
