Abstract	In the context of a transforming market, fuzzy inventory system is important for researchers to deal with uncertainty and imprecision. This paper deals with an inventory model with selling price dependent demand and two parameter Weibull deteriorating items with reliability consideration. In this model, shortages are not allowed. Since imperfect production process is considered but it is not re-workable. Due to un-certainty in the market, this inventory model is solved under crisp and fuzzy environment both to evaluate the optimum solutions in different cases. In this model, Centroid Method and Signed Distance Method are used to defuzzify the total cost. Sensitivity analysis is employed to illustrate the example under crisp and fuzziness.
