Several researchers have recently derived formulae for economic order quantities (EOQs) with some variants without reference to the use of derivatives, neither for first-order necessary conditions nor for second-order sufficient conditions. In addition, this algebraic derivation immediately produces an individual formula for evaluating the minimum expected total annual cost. The purpose of this...

a r t i c l e i n f o This paper expands an inventory model for deteriorating items with stock-dependent demand. This model provides time varying backlogging rate as well as time varying deterioration rate. The aim of this model is to determine the optimal cycle length of each product such that the expected total cost (holding, shortage, ordering, deterioration and opportunity cost) is minimize...

In traditional inventory models such as the economic order quantity (EOQ) and the economic production quantity (EPQ) the sole objective is to minimize the total inventory-related costs, typically holding cost and ordering cost. These models do not consider the presence of defective products in the lot or rework of them. Recently, Jamal, Sarker, and Mondal (Jamal, A. A. M., Sarker, B. R., & Mond...

Business organizations that deal with consumable and perishable items have consistently incurred enormous loss as a result of the nature their goods. The losses direct negative impact on revenues. Unplanned lack precise production prediction models are responsible for this. An appropriate model, developed to guide plan processes will help manufacturers in deciding which product make what quanti...

Lack of purchasing planning and proper demand forecasting causes hospitals to suffer from drug inventory mismatches with actual demand; in other words, the management cost is high if quantity exceeds or less demand. Therefore, this research aimed plan an appropriate purchase reduce costs effectively meet hospital's pharmaceutical needs a case study: i) for 29 AV drugs using Minitab 19, ii) econ...

This research is in the field of culinary business where raw materials if stored for too long can cause damage as well losses to owner. The businesses chosen were those Cireng and Cimol Nella which had problems supplying materials, namely flour. also aims enable actors carry out an inventory so that product quality better maintained it does not change taste condition even better. From existing ...

We consider a continuous review inventory system that faces two different cases of demand processes. In one case demand follows a compound Poisson process. In the other case demand is a combination of a constant deterministic component and a random component which follows a compound Poisson process. We assume negligible lead time. Orders occur when inventory level drops to or below level zero, ...
