In this paper, we have considered an EOQ inventory model with a price-dependent demand
and time varying holding cost in fuzzy environments by employing trapezoidal fuzzy …

The fuzzy set is a crisp set extension that manages ambiguity and uncertainty more
tastefully. An extra tool that may be used to represent the uncertainty is the notion of the …

In this paper, I have developed a multi item production inventory model for the non-
deteriorating items with constant demand rate under the limitation on set up cost. The …

In present study, a fuzzy inventory model is elaborated for perishable items with stock-level
dependent demand and constant lead time. Fuzziness is considered by permitting the cost …

This paper investigates a coupled system of nonlinear fuzzy Volterra–Urysohn integral
equations. Here, we have studied the existence of at least one continuous solution. As an …

In a bi-level programming, coefficients in the objective functions and the constraints may not
to be fixed real numbers due to the presence of uncertainties in the domain of the model …
