摘　　要：Purpose–This study aims to develop a cause-effect relationship between criteria that contribute to water security using the Intuitionistic Fuzzy-Decision-Making Trial and Evaluation Laboratory(IF-DEMATEL)method.Differently from the typical DEMATEL which utilizes crisp numbers,this modification introduces intuitionistic fuzzy numbers(IFNs)to enhance judgments in a group decision-making environment.In particular,the linguistic variables used in IF-DEMATEL are defined using the concept of three-tuple of IFNs.Design/methodology/approach–Data with the linguistic variable“influence”were collected from a group of experts in water security via personalunstructured interviews.Seven water security criteria are considered in this study.Computational software was employed to execute the computational procedures of the IF-DEMATEL method.It is anticipated that by taking into account the hesitation degree of IFNs will reflect the scenario in real life,which could lead to precise decision-making.Findings–Theresultsshowthat“Over-Abstraction”,“SaltwaterIntrusion”and“LimitedInfrastructures”are the cause criteria that contribute to water security.In addition,the relationship map of influence shows that“Water Pollution”and“Rapid Urbanization”are the most vulnerable criteria as these two criteria are most easily affected by other criteria in a unidirectional relation.Practicalimplications–It is anticipated that these findings will serve as useful references for water security management and policymakers.Originality/value–The present study makes a noteworthy contribution to the modification of DEMATEL where three-tuple of intuitionistic fuzzy numbers are considered in the computations.The present study also provides additional evidence with respect to factors that contribute to water security.
