In this research study, we present a novel frame work for handling bipolar fuzzy soft information by combining bipolar fuzzy soft sets with graphs. We introduce several basic notions concerning bipolar fuzzy soft graphs and investigate some related properties. We also consider the application of the bipolar fuzzy soft graphs. In particular, three efficient algorithms are developed to solve mult...

Probabilistic hesitant fuzzy set (PHFS) is a fruitful concept that adds to hesitant fuzzy set (HFS) the term of probability which is able to retain more information than the usual HFS. Here, we demonstrate that the existing definitions of PHFS are not still reasonable, and therefore, we first improve the PHFS definition. By endowing the set and algebraic operations with a new re-definition of P...

Background The concept of decision space holds appeal as an approach to disaggregating the elements that may influence decision-making in decentralized systems. This narrative review aims to explore the functioning of decision space and the factors that influence decision space.   Methods A narrative review of the literature was conducted with searches of online databases and academic journals ...

Disposal of health-care waste (HCW) is considered as an important environmental problem especially in large cities. Multiple criteria decision making (MCDM) techniques are apt to deal with quantitative and qualitative considerations of the health-care waste management (HCWM) problems. This research proposes a fuzzy multi-criteria group decision making approach with a multilevel hierarchical str...

This paper presents the combined use of standard DEMATEL and AHP methodologies in assessing a selected set criteria for evaluating sustainable forestry goals. Creating decision-making framework with two participating individuals (the authors this research) enabled comparison individually obtained solutions aggregated derived by methodologies. The strategic viewing causality relations among limi...

Decision matrix in group decision making problems depends on a lot of criteria. It is essential to know the necessity ofweight or coefficient of each criterion. Accurate and precise selection of weight will help to achieve the intended goal.The aim of this article is to introduce a linear programming model for recognizing the importance of each criterion inmulti criteria group decision making w...

one of important issues in designing a supply chain is supplier selection. this issue is complicated, because each supplier should satisfy some criteria from buyer and choosing among them is actually a multi criteria decision making problem. so, there is a need for a structured and systematic approach to solve this problem. in this article, we address supplier selection in an advertising indust...

The performance of an organization is usually appraised in terms of multiple criteria using a group of expert panels. However, when a decision is highly complex coupled with personal interests and emotional factors, a rational technique is necessary to extract the individual preferences objectively in order to optimize the decision outcomes. This article proposes a new evaluating technique for ...
