Abstract

The aim of this study is to determine the main risk factors affecting adult entertainment
economics and to rank them using the CPF-OCRA methodology with
relative closeness weighting. The proposed framework addresses limitations of
conventional fuzzy ranking models by integrating relative closeness coefficients
with circular Pythagorean fuzzy numbers. We propose three main contributions,
namely, (1) a new distance measurement for the CPFS, (2) a criteria weighting
method with the relative closeness coefficients, and (3) an operational competitiveness
rating method for the CPFS. The model is validated on the data provided
by experts on the adult entertainment risk assessment. Comparative analysis
with seven MCDM methods (TOPSIS, VIKOR, COPRAS, ELECTRE II, PROMETHEE,
MABAC, WASPAS) shows strong correlation (avg. 0.96), confirming consistency.
Sensitivity analysis demonstrates ranking stability up to ±20% weight perturbation.
Results indicate that regulated harmony is the optimal strategy, followed by
urban prohibition.
