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.
