An EOQ model of inventory for items with linear rate of deterioration is considered, taking the demand rate to be dependent on the stocjk level at any instant of time. The Payments are permitted to be delayed up to certain period of time. Shortages are not allowed. After the certain period, a special discount is permitted to reduce the stock in inventory because if the stock is holded, an inter...

In this note, we consider a variation of the economic order quantity (EOQ) model where cumulative holding cost is a nonlinear function of time. This problem has been studied by Weiss (1982), and we here show how it is an approximation of the optimal order quantity for perishable goods, such as milk, and produce, sold in small to medium size grocery stores where there are delivery surcharges due...

For several decades, the Economic Order Quantity (EOQ) model and its variations have received much attention from researchers. Recently, there has been an investigation into an EOQ model incorporating a random product life cycle and the concept of time-value of money. This paper extends the previous research in several areas. First, we investigate the impact of in ̄ation on the choice of repleni...

We study an EOQ inventory model with demand rate and holding cost rate per unit time, both potentially dependent on the stock level. The ordering cost, the holding cost and the gross profit from the sale of the item are considered. The objective is to maximize the average profit per unit time. We present the analytical formulation of the problem and demonstrate the existence and uniqueness of t...

This study aims to analyze and show how calculate EOQ prove that the use of method can make inventory costs efficient because number purchases is not excessive lacking, frequency exact time reordering. The theory underlying this research management, especially Single Item Method. analysis technique used descriptive using Optimalization , purchase (N), Reorder Point (ROP) results showed cost eff...

In this paper, we use quasi-variational inequalities to provide a rigorous proof of the familiar square root formula for the optimal economic order quantity (EOQ) in the classical deterministic average cost inventory model.

Hasil penelitian ini bertujuan untuk membantu menganalisis manajemen persediaan pada warung makan Ayam Sunda. Selama penelitian, metode kualitatif diterapkan dengan melakukan wawancara langsung pemilik Sunda mendapatkan data yang digunakan dalam perhitungan persediaan. Berdasarkan wawancara, tersebut mengaku belum pernah pengelolaan Oleh karena itu, mencoba menghitung biaya pemesanan dan penyim...

In this paper, a discrete single-level multi-component inventory control model for assembly systems with random component procurement lead times is considered. The economic order quantity (EOQ) policy is used for a type of finished product. The requirements of the components are constant and cyclic (periodic), and their values per period are deduced from the EOQ for the finished product. The pa...

The economic order quantity (EOQ) and the economic production quantity (EPQ) are well-known and commonly used inventory control techniques. The standard results are easy to apply but are based on a number of unrealistic assumptions. One of the assumption is that the demand is normally distributed in any interval. In several practical cases the assumption about independence of successive demands...
