In this paper, an inventory model is developed for deteriorating items that deteriorates at a Weibull distributed rate, assuming the demand rate as a ramp type function of time. Shortages are allowed and completely back logged. The deterioration rate is a special form of two parameters Weibull distribution function considered by Covert and Philip [4]. Deterioration rate is considered to be a function of time and some other parameters such as temperature, humidity etc. Model is solved by cost minimizing criterion. Finally numerical examples are given to illustrate the results obtained.
