Evaluating Kidney Failure in Age Groups with Cubic Neutrosophic Sets

This study presents a multi criteria decision making (MCDM) approach based on the cubic neutro sophic TOPSIS method with a score function to evaluate kidney failure across different age groups. Patients are assessed based on symptoms and these symptoms are linked to diseases to form a complete patient disease relationship. The cubic neutrosophic framework handles uncertainty and imprecision in medical data, and the score function ensures accurate ranking of alternatives. Real patient data are analyzed to determine the level of susceptibility to kidney failure among children (0- 17), adults (18- 49), and the elderly (50 +). The findings show that the elderly group is the most susceptible to kidney failure, emphasizing the importance of early diagnosis and preventive measures in this population.
