In this paper a mathematical model of the economic order quantity with two storage facilities for single item has been considered under the condition that when the fixed delay in payments are permissible by the supplier. In practice, however, supplier allows some fixed delay in settling the...

When a price change is announced in an inventory system, a one time decision has to be made to purchase a large quantity Q’ before the price change becomes effective, to take advantage of current lower price. In this note, we consider a system having a limited storage capacity W Q’, so that...

In this paper a mathematical model of order level lot-size inventory model under permissible delay in payment is considered with two storage facilities. The supplier allows time for settling payments for no interest charges are payable. Here an inventory system under consideration does not have...

In this paper a periodic review probabilistic inventory model for a single item with two storage facilities is developed; one warehouse is owned by the system under consideration (which is referred to as OW) and the other is a rented warehouse (RW). The capacity of OW is W units. Any quantity...
