We study a periodic-review inventory system with remanufacturing for a perishable product with a lifetime of two periods. There are two separate demands for different ages of the product and stockout substitution is considered. One distinctive feature is that a random portion of the sold product with two-period lifetime is returned and can be remanufactured into product with one-period lifetime. We show that the optimal remanufacturing policy is a modified base-stock policy and the optimal manufacturing quantity is decreasing in the total inventory after remanufacturing. Numerical study is conducted to study the effects of the remanufacturing and demand substitution.
