In the traditional economic order quantity/economic production quantity model, most of items considered are perfect type. But this situation rarely takes place in practice. Thus, paper, an model with imperfect-quality is developed. $$100\%$$ screening process performed, and imperfect quality sold as a single batch. A proportionate rate discount for has also been studied. Moreover, case study incorporated to comprehend model. To nullify issues non-random uncertainties demand business scenario, cloudy fuzzy method utilized here. Numerical reveals that cloud along its new defuzzification methods can give maximum profit all time instead deterministic ones. Finally, sensitivity analysis graphical illustrations made justify novelty
