Using TODIM Approach with TOPSIS and Pythagorean Fuzzy Sets for MCDM Problems in the Bullwhip Effect

The aim of this paper was to explore decision-making using Pythagorean fuzzy sets with an acronym in Portuguese for Interactive multi-criteria decision making (TODIM) approach. We propose a novel model that TODIM integrates the technique order preference by similarity ideal solution (TOPSIS) and concepts solve problems related core alternatives facing innovative companies under bullwhip effect (BWE). Our findings indicate demand forecast updating (A1) represents compromise solution. proposed offers approach select best alternative manage optimizing decision- making. new concept PF-TODIM approach, based on preferences, optimal similarity-based measure, distance-based complete research method. This is first apply method (MCDM) ambiguous environment BWE, thereby providing decision-makers directions designing management models setting business strategies determine target markets. From perspective enterprises, precise handling uncertainly factors principal strategy success.
