While the development and application of inventory control models of deterioration products is one of the main concerns of researchers and practitioners, most studies done in this field have focused on inventory models under fixed supply lead time assumption. In this paper, at first we study researches done in inventory control of deteriorating items and classify them based on modeling approach...

In this study a deterministic inventory model for deteriorating items with stock dependent demand is developed. In this model the shortages are allowed and partially backlogged and the effect of inflation rate and delay in payments are discussed. This paper establishes an inventory model for the deteriorating items and stock dependent demand rate under inflation when the supplier offers a permi...

The study of agricultural product's inventory is significant to lower its logistics cost, reduce the waste during the logistics courses and guarantee its quality. Deteriorating items can be studied by the way of literature review according to time varying of demand, inventory shortage and deteriorating rate while multi-warehouse according to the number of renting warehouse, capacity and demand ...

Profitably managing inventories is always a big challenge for retailers in the current context of transparent and competitive business. A general retailer needs to handle both deteriorating non-deteriorating products simultaneously run Deterioration sometimes impacts retailer’s profits badly—a situation which can be alleviated by implementing proper preservation technology. In addition, improve...

Using data from the PISA 2006 field trial, Rasch item response models are used to demonstrate that extreme response tendency was exhibited differentially across culturally distinct countries when answering Likert type attitude items. A single attitude scale is examined across eight culturally distinct countries in this paper. Two avenues to ameliorate this tendency are explored: first using dic...

In this paper, we attempt to develop an inventory model for deteriorating items with the consideration of the fact that the use of preservation technology (PT) can reduce the deterioration rate significantly. In this model the shortages are allowed and salvage value is incorporated to the deteriorated items. Demand rate is constant, deterioration rate is time dependent with Weibull’s distributi...
