Abstract

Smart technologies play a significant role in the management of sewage and drainage systems by improving operational efficiency, particularly in critical situations. In modern cities, water distribution networks, drainage systems, and wastewater treatment plants face increasing pressure due to rapid urbanization and population growth. Selecting advanced smart technologies for the effective management of sewage and drainage systems requires an efficient decision-making framework capable of evaluating multiple technological alternatives against conflicting criteria. In this context, the circular spherical fuzzy set (Cir-SFS) provides an effective framework for handling uncertainty and ambiguity in complex real-world decision-making problems. This study extends the theoretical concept of Frank algebraic operations within the circular spherical fuzzy (Cir-SF) environment. Furthermore, a family of robust aggregation operators, including the Cir-SF Frank Weighted Average (Cir-SFFWA) and Cir-SF Frank Weighted Geometric (Cir-SFFWG) operators, is developed. The weighted aggregate sum product assessment (WASPAS) method is also extended under the Cir-SF environment to address multi-criteria decision-making (MCDM) problems. An illustrative numerical example is presented to demonstrate the applicability and effectiveness of the proposed methodology in ranking smart technologies based on multiple conflicting criteria. Finally, comparative and sensitivity analyses are conducted to verify the robustness, consistency, and superiority of the proposed approach over existing decision-making methods.
