In this article, linearly deteriorating EOQ models have been developed for imperfect quality
items (both crisp and fuzzy models) with linear and price dependent demand. The price depended demand
is considered as two different types of fuzzy number viz. trapezoidal and cloudy fuzzy model.
Defuzzification has been done using signed distance method and Yager‘s Ranking Index. All results are
verified numerically and graphically for both models. Sensitivity analysis of the model is carried out to
validate the models for optimality.
