A Trapezoidal Fermatean Fuzzy Decision‑Making Framework Using Aczel‑Alsina Operators for Disaster Management

This paper introduces trapezoidal-valued Fermatean fuzzy (TpVFF) numbers based on the Aczel-Alsina (AA) t-norm and t-conorm operations. New operational laws, including addition, multiplication, and scalar multiplication, are defined. Based on these operations, several geometric aggregation operators, including weighted...

Multi-agent Decision-Making Systems for Innovative Investment Models in Net-Negative Emission Technologies

Today, simply reducing carbon emissions is not enough to combat climate change; the existing carbon dioxide stock in the atmosphere must also be effectively eliminated. However, the factors that determine the success of investments in this area and the most appropriate financial models to support these investments have...
