The main purpose of this paper wants to investigate the optimal retailer’s lot-sizing policy with two warehouses under partially permissible delay in payments within the economic order quantity (EOQ) framework. In this paper, we want to extend that fully permissible delay in payments to the supplier would offer the retailer partially permissible delay in payments. That is, the retailer must mak...

A continuous production control inventory model for deteriorating items with variable demand rate is developed. Demand rate is the linear function of time. In this paper we have done all work in the environment of permissible delay of payments. A number of structural properties of the inventory system are studied analytically. We have discussed the minimum total system cost under the condition ...

This paper derives a production model for the lot-size inventory system with finite production rate, taking into consideration the effect of decay and the condition of permissible delay in payments, in which the restrictive assumption of a permissible delay is relaxed to that at the end of the credit period, the retailer will make a partial payment on total purchasing cost to the supplier and p...

This study develops an inventory model for determining an optimal ordering policy for non-deteriorating items and time-dependent holding cost with delayed payments permitted by the supplier under inflation and time-discounting. The discounted cash flows approach is applied to study the problem analysis. Mathematical models have been derived under two different situations i.e. case I: The permis...

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...

This paper deals with an inflation induced stock dependent demand inventory model with permissible delay in payments. In real life situations, some products maintain freshness and quality for some time. This inventory model is developed for non-instantaneous deteriorating items. The purpose of this paper is to obtain the optimal policies for maximizing the total profits. Numerical examples are ...
