In this paper, the idea of the bipolar Pythagorean fuzzy sets (BPFSs) and its activities, which
is a generalization of fuzzy sets, bipolar fuzzy sets (BFSs), intuitionistic fuzzy sets and bipolar …

In this paper, a new approach was applied to a single-item single-source ($ SISS $) system
at the" $ EOQ-type $" mode considering imperfect items and uncertainty environment. The …

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 …

This paper considers a dual-channel closed-loop supply chain consisting of a manufacturer,
a retailer and a collector in which the retailer possesses private demand information and …

Multi-item inventory model with stock-dependent demand is developed in fuzzy
environment. Items are deteriorated in constant rate and are sold from different outlets in the …

We study data-driven decision support and formalise a path from data to decision making.
We focus on lot sizing in inventory management with stochastic demand and propose an …

A multi-objective, multi-item fuzzy stochastic inventory model is constructed for deteriorating
items under limited storage space as well as capital investment. Demand is considered as a …

This paper considers a closed-loop supply chain comprising one retailer and two suppliers.
It assumes one supplier as the main supplier and another as the backup. The coordination …

A suggested algorithm to solve triangular fuzzy rough integer linear programming (TFRILP)
problems with α-level is introduced in this paper in order to find rough value optimal …

The aim of this article is an effort to initiate the cloudy fuzzy number in developing classical
economic production lot-size model of an item produced in scrappy production process with …
