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.

Data with the linguistic variable “influence” were collected from a group of experts in water security via personal unstructured 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.

The results show that “Over-Abstraction”, “Saltwater Intrusion” and “Limited Infrastructures” 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.

It is anticipated that these findings will serve as useful references for water security management and policymakers.

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.

The aim of the study was to determine the region brand’s strength by measuring the awareness of the regional brand elements, associations and the perception of the region’s promotional activity in the corporate customers’ group.

To obtain the necessary data, this study conducted computer-assisted web interviewing on a sample of 151 small and medium-sized enterprises (SMEs) registered in the Mazowieckie Voivodeship and engaged in furniture production and food and beverage production. Statistical data analysis included Pearson and Spearman’s rank correlation and chi-square tests.

The survey showed a high number of brand associations with the region of Mazovia, but the level of brand recognition was low. The awareness of the region’s logo among SMEs shows the strongest correlation with the belief that promotional activities increased the scope of company operations. Moreover, this evidences the perceived utility of the brand among those customers.

The regional authorities should invest more in the frequency of promoting the region among certain strongly engaged user groups to increase their brand awareness level. Furthermore, local authorities should try establishing an umbrella brand that would cover several sub-brands promoting separate industries in the region.

To the best of the authors’ knowledge, this is the first study in Poland that focused on regional branding effects among entrepreneurs and using a quantitative method. The relationship between the studied entrepreneurs’ willingness to use the Mazovia brand and their range of operations indicates that some enterprises already enjoy greater trust thanks to the brand, which increases their loyalty toward the region.
