Abstract

A number of inventory models have discussed the effect of deterioration in the past researches. Generally it has been assumed that items start deteriorating as soon as they arrive in the warehouse. But in real life there are numerous products like fruits, vegetables, meat, milk etc. that have a shelf life and start deteriorating after a time lag. This means that for some initial period of time, there is no deterioration in items. This phenomenon is termed as non-instantaneous deterioration and the items are termed as non-instantaneous deteriorating items. In the present paper, an inventory model for non-instantaneous deteriorating items with price dependent demand has been developed. Moreover, the holding cost is assumed to be time dependent. Further shortages are also allowed subject to full backlogging. The results have been elucidated with numerical examples.
