ASYMPTOTIC RESULTS FOR THE ERGODIC DISTRIBUTION OF AN INVENTORY MODEL WITH FUZZY DEMANDS

In this paper, a renewal-reward process which represents a fuzzy inventory model of type (s, S) with a discrete interference of chance is investigated. By utilizing the expression of the ergodic distribution of this process in terms of a fuzzy renewal function, asymptotic expansions for the alpha-cuts of this ergodic distribution is obtained when the interferences have a Weibull distribution with a fuzzy parameter.
