An inventory problem with processed and non-processed products of same perishable goods

Abstract

In the field of inventory problems, several researchers have been interested in inventory control for a perishable product such as blood, fresh fruit, milk, film etc. Though there are huge number of research papers on perishable inventory, we only cite related papers ([1], [2],[3], [4]). This paper considers two types of products for same perishable goods such as matured tomato and un-matured one, fresh milk and processed milk etc. That is, one is very fresh and so its lifetime is one. The other is not so fresh and its lifetime is two. We consider how to order two products.
