In this study, an EOQ (Economic Order Quantity) inventory mathematical model is constructed for a deteriorating item having time dependent demand when delay in payment is permissible. The deterioration rate is assumed to be a constant and the time varying demand rate is taken to be an exponential declining function of time. Mathematical models are also derived under two different circumstances,...

This paper deals with the problem of determining the economic order quantity for exponentially deteriorating items under the conditions of permissible delay in payments. The delay in payments depends on the quantity ordered. When the order quantity is less than at which the delay in payments is permitted, the payment for the product must be made immediately. Otherwise, the 0xed trade credit per...

This study presents an inventory model to determine an optimal ordering policy for non-deteriorating items and timedependent demand rate with delay in payments permitted by the supplier under inflation and time discounting. Mathematical models have been derived under two different situations, i.e. Case I: The permissible delay period is less than or equal to replenishment cycle period for settl...

Ödemede belirli bir süre gecikmeye izin verilmesi varsayımının toplam maliyet üzerindeki etkisi birçok üretim stok kontrol modelinde ele alınmıştır. Bu modellerde, ödemede verilen gecikme süresinin alıcının satın alma kararını etkilediği bu durumun da maliyetlerini önemli ölçüde azalttığı sonucuna varılmıştır. Stok azaltmanın diğer yolu sırasında üretilen kusurlu ürünlerin tamir edilmesidir. ça...

In this paper, an integrated production-inventory model is presented for a supplier, manufacturer, and retailer supply chain under conditionally permissible delay in payments in uncertain environments. The supplier produces the item at a certain rate, which is a decision variable, and purchases the item to the manufacturer. The manufacturer has also purchased and produced the item in a finite r...

In most of the classical inventory models the demand is considered as constant. In this paper the model has been framed to study the items whose demand and deterioration both are constant. The authors developed a model to determine an optimal order quantity by using calculus technique of maxima and minima. Thus, it helps a retailer to decide its optimal ordering quantity under the constraints o...

This paper develops a supply chain framework where payments take place with permissible delays. Unlike other studies, the is modelled as closed-loop system, in which returning products incorporated into classical models and full backorder permitted. Among most important research questions order amount of members to maximize Retailer delays profit chains. The study determines portion time interv...

whether for the delay in payment of debt resulting from civil liability can be demand late payment damages? in answering this question, answer of some of lawyers is positive. they believed that late payment damages is accrued to debt resulting from civil liability. because, these creditors are more deserving of protection. also, the word of debt in article 522 of code civil procedure is absolut...
