Abstract
The effect of two issuing policies, LIFO and FIFO, on the inventory level in a production lot size model for items with varying rate of deterioration is studied
An implicit form of inventory level under each policy is developed for each phase of a cycle which is shown to be consistent with known extreme cases
A numerical solution procedure employing the Runge-Kutta method and Simpson's Rule is developed to select a preferable policy in terms of the amount deteriorated per unit time.
