Integrating IVIFS and Butcher’s RK Method for Multiple Attribute Group Decision Making: Mobile Brand Selection

Problems in MAGDM (Multiple Attribute Group Decision Making) are examined using IVIFS (Interval-Valued Intuitionistic Fuzzy Sets). To aggregate the Interval-Valued Intuitionistic Fuzzy Decision Matrices (IVIFDM), subjective geometric & hybrid geometric operators are employed. Decision-maker weights are determined using Runge-Kutta methods, which are applied to the decision-making process. A new Extended Hamming Distance formula is used to rank the alternatives. A numerical instancehad been given to demonstrate effectiveness of proposed method.
