Possibility and necessity constraints and their defuzzification - A multi-item production-inventory scenario via optimal control theory


In this paper, analogous to chance constraints, real-life necessity and possibility constraints in the context of a multiitem dynamic production-inventory control system are defined and defuzzified following fuzzy relations. Hence, a realistic multi-item production-inventory model with shortages and fuzzy constraints has been formulated and solved for… (More)
