Since the term “Fuzzy differential equations”(FDEs) emerged in the literature in 1978,
prevailing research effort has been dedicated not only to the development of the concepts …

While the basic economic order quantity model has found some practical applications, it
makes a number of assumptions which do not reflect most real life inventory systems. This …

In this article, we have solved the type-2 fuzzy differential equation. The nonlinear type-2
triangular fuzzy numbers (NT2TFNs) are taken, and their different arithmetic properties are …

This paper addresses the differential pricing and lot-sizing problem for a perishable item
with multiple demand classes under a two-level trade credit. The distributer sells a single …

In this article, an economic order quantity model has been studied in view of joint impacts of
the memory and learning due to experiences on the decision-making process where …

In this paper, an attempt to find a more generalized version of the classical EOQ model is
made under the setup of fuzzy fractional calculus. Intuitively, the notions of fuzziness and …

The concepts of generalized Hukuhara difference and interval differential equation play
important role in the theory of interval uncertainty. These concepts have many applications …

In this paper, we study first order linear fuzzy systems under generalized differentiability and
present the general form of their solutions. Next, the fuzzy optimal control problem of these …

The central concern of this article is to define Laplace transformation for neutrosophic valued
function and an application for manifesting an economic optimization model. Neutrosophy …

In this study, an economic production quantity (EPQ) model with deterioration is developed
where the production rate is stock dependent and the demand rate is unit selling price and …
