An Intuitionistic Fuzzy Decision-Making for Developing Cause and Effect Criteria of Subcontractors Selection

Abstract

The decision-making trial and evaluation laboratory (DEMATEL) method has been applied to solve numerous multi-criteria decision-making (MCDM) problems where crisp numbers are utilized in defining linguistic evaluation. Previous literature suggests that the intuitionistic fuzzy DEMATEL (IF-DEMATEL) can offer a new decision-making method in solving MCDM problems where intuitionistic fuzzy sets (IFSs) are utilized in defining linguistic evaluation. This paper aims to develop a cause-effect diagram of subcontractor selection using a modified IF-DEMATEL method. In this paper, three modifications are made to the IF-DEMATEL method. Two memberships of IFSs, relative weights of experts, and a transformation equation are the elements introduced to the IF-DEMATEL. The linguistic variables that defined in IFSs are meant to capture wide arrays of uncertain and fuzzy information in solving MCDM problems. Furthermore, the modified IF-DEMATEL is applied it to a subcontractors' selection problem where groups of cause and effect criteria are segregated. A group of experts' opinions were sought to provide linguistic evaluations regarding the degree of influence between criteria in subcontractors' selection. The results show that four criteria are identified as cause criteria while six other criteria are identified as effect criteria. The results also suggest that the criteria "experience" is the main cause that influence the selection of subcontractors. The identification of cause and effect criteria would be a great significance for practical implementation of subcontractors' selection.

Intuitionistic fuzzy DEMATEL for developing causal relationship of water security

“…Step 2 and Step 8 are taken from Govindan et al (2015), then Step 4 is taken from Xu (2007) while Step 5 is transforming the aggregated IFN matrix into the aggregated crisp matrix using the equation adopted from Varghese and Kuriakose (2012). Arithmetic means the equation adopted from Abdullah et al (2021) is used to determine the threshold value which is subsequently used in developing network relationship maps. Other steps remained the same as the algorithm proposed by Büyüközkan et al (2017).…”

“…The IF-DEMATEL is an MCDM method based on intuitionistic fuzzy sets in which the relationship among criteria can be identified. Recent applications of the IF-DEMATEL method are found in many areas of literature such as knowledge management (Patil and Kant, 2014), supply chain (Mangla et al , 2016; Büyüksaatçi et al , 2020; Topgul et al , 2021), marketing resources Altuntas and Yilmaz (2016), solar power enablers (Luthra et al , 2016), energy (Erol et al , 2021), subcontractor selection (Abdullah et al , 2021) just to mention a few. These several IF-DEMATEL studies demonstrate the method's effectiveness whenever decisions must be determined under challenging circumstances.…”

Prioritization and the Direction of Effect and Impressionability of Information Literacy Components by DEMATEL Technique

“…It should be kept in mind that, to properly attain a system's educational objectives, the interactions of components must be taken into account. Since decisions are adopted and assessed based on the priority of components, achievements may be enhanced in such educational systems (Abdullah, Ong, & Rahim, 2021). So far, however, information literacy skills have been neglected in information literacy research and curricula.…”

Pythagorean Fuzzy AHP Based Dynamic Subcontractor Management Framework

“…Nov and Peansupap [20] stated that the MCs have wrong practices in selecting SCs and thereupon developed a new model using artificial neural networks to determine the type of relationship between MC and SC. Abdullah et al [21] conducted a study aiming to develop the cause-effect diagram of the SC selection and as a result, showing that the "experience" criterion is the main factor affecting the SC selection. Afshar et al [22] stated that SC selection is a very time-consuming element in cases where multiple projects are undertaken by the same contractor, and presented an optimized model that enables SC selection and projects to be scheduled and facilitated to be executed.…”
