Abstract
An inventory model is considered in which it is depleted not only by demand, but also by deterioration. The Weibull distribution, which is capable of representing constant, increasing and decreasing rates of deterioration, is used to represent the distribution of the time to deterioration. Hence, we derive the EOQ model for inventory of item that deteriorates at a Weibull distributed rate, assuming the demand rate a ramp type function of time. Finally a numerical example has been studied along with its sensitivity.
