Inventory models play a leading role in analyzing a lot of realistic situations arising at places like, food and vegetable markets, market yards, oil exploration industries, etc. In the present article, we developed an inventory model for deteriorating items with permissible delay in payment under inflation. In the given model, demand rate is considered as stock-dependent and deterioration rate...

Usually it is assumed that all items in a lot are of good quality, but in reality this assumption may not always be pertinent. Thus, the inspection of lots becomes essential in almost all organizations. Moreover, its role becomes more vital when the items are deteriorating in nature. Owing to this fact, this paper investigates the impact of initial inspection on retailer’s pricing and ordering ...

 This study presents an inventory model for deteriorating items with linearly time-dependent demand rate under trade credits. Mathematical models have been derived under four different situations i.e. Case 1 : The cycle time T is greater than or equal to M1, to get a cash discount, Case 2 : The cycle time T is less than M1, Case 3 : The cycle time is greater than or equal to M2, and Case 4 : T...

As a matter of fact, the capacity of any warehouse is limited, so a firm has to hire a warehouse called rented warehouse (RW) for storing the excess units over the fixed capacity W (say) of the own warehouse (OW). Practically the RW is assumed to offer better storing facilities than the OW, which results in a lower rate of deterioration and is supposed to charge higher holding cost than the OW....

The traditional economic production quantity (EPQ) model assumes that the production products are all perfect. It is not always true in the real production system, due to imperfect production process or other factors, imperfect quality items may be produced. Furthermore, it is well-known that the total production-inventory costs can be reduced by reworking the imperfect quality items produced w...
