Neutrosophic Sets and Systems
Abstract
The evaluation of the social benefits of major sports events is a multifaceted process, focusing on assessing the positive impacts such events bring to a host city and society. These benefits include promoting public health, fostering national pride and social cohesion, boosting local economies, and improving infrastructure. This evaluation process can be viewed as a multiple-attribute decision making (MADM) problem. This study introduces a novel double-valued neutrosophic number CoCoSo (DVNN-CoCoSo) technique for MADM, incorporating DVNN Hamming distance (DVNNHD) and DVNN Logarithmic distance (DVNNLD). This method effectively handles the uncertainty inherent in evaluating social benefits. A numerical example of social benefits evaluation for major sports events illustrates the practicality and efficacy of the DVNN-CoCoSo technique. The study's major contributions include the development of the DVNN-CoCoSo technique for MADM, the consideration of objective weights through entropy techniques, and the application of this novel method to the social benefits evaluation of major sports events.
