Derivation of the Optimal Solution for the Economic Production Quantity Model with Planned Shortages without Derivatives

Modelling, 2022
In this paper, we study a reformulation of the Economic Production Quantity (EPQ) problem. We study a more general version of the problem first and derive the conditions for an optimal solution, as well as the optimal solution itself, all without using ...

Arbitrary-order economic production quantity model with and without deterioration: generalized point of view

Advances in Difference Equations, 2020
The key objective of this paper is to study and discuss the application of fractional calculus on an arbitrary-order inventory control problem. Using the concepts of fractional calculus followed by fractional derivative, we construct different possible ...
