Fuzzy quantum-inspired MCDM for smart city renewable hub selection

Smart cities are transitioning towards sustainable energy infrastructure. This transformation requires robust decision-making systems to handle the intricacies of imprecision, uncertainty, ambiguity and conflicting criteria. This research proposes a fuzzy quantum-based multi-criteria decision-making (MCDM) approach for optimal location selection of renewable energy hubs. The developed model is the intersection of fuzzy logic, quantum decision theory and MCDM. The key criteria considered in this study include costs, energy efficacy, environmental impact, scalability and compatibility. The results obtained through this integrated method are more reliable and consistent. The rankings of the alternatives are compared with the existing traditional approaches to demonstrate the competency of the proposed method. Sensitivity analysis exhibits the increased efficiency of the fuzzy quantum-based MCDM approach.
