This paper considers the impact of inflation on the EPQ model for deteriorating items subject to random machine breakdowns and fixed maintenance period. The demand rate is assumed to be a function of inflation and the demand increase due to inflation. The objective is to determine the optimal production uptime that minimizes the present value of expected total costs per unit time consisting of ...

A deterministic inventory model with two levels of storage (own warehouse and rented warehouse) with non-instantaneous deteriorating items is studied. The supplier offers the retailer a trade credit period to settle the amount. Different scenarios based on the deterioration and the trade credit period have been considered. In this article, we have framed two models considering single warehouse ...

This paper develops an inventory model for non deteriorating items with time dependent demand rate of production with constant inflation rate. In this model shortages are not allowed, the effect of inflation rate and delay in payments are discussed. In the study mathematical models are also derived under two different cases, i.e. Case-I the credit period is less than or equal to the cycle time ...

in the supplier selection problem considering both parties benefits including the buyer and the supplier, is one of the key factors to enhance the supply chain management performance as well as sustaining a long term relationship with the suppliers. in fact, the integrated supplier selection models have been discussed in order to confirm the aforementioned subject. in this research, an integrat...

In practices, the supplier may simultaneously offer the customer: (1) a permissible delay in payments to attract new customers and increase sales, and (2) a cash discount to motivate faster payment and reduce credit expenses. Since all cash outflows related to inventory control that occur at different points of time have different values, we use the discount cash-flow (or DCF) approach to esta...

Inventory models for deteriorating items of a supply chain is critical essence to the maritime industry. This study proposes real and economically efficient multicriteria inventory policy with nonlinear ramp functions permissible delay in payment under inflation, two conditions Shortages Followed by (SFI) (IFS) have been considered formulation models. Both consist ordering cost, unit deteriorat...

In this paper, an inventory model of a deteriorating item with stock and selling price dependent demand under two-level credit period has been developed. Here, the retailer enjoys a price discount if he pays normal purchase cost on or before the first level of credit period, or an interest is charged for the delay of payments. In return, retailer also offers a fixed credit period to his custome...

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 ...
