An AHP-PROMETHEE II method for 2-tuple linguistic multicriteria group decision making

The paper aims to propose a hybrid AHPPROMETHEE II method for multicriteria group decision making problems where the criteria values take the 2-tuple linguistic information. The method can be seen as an extension of the traditional analytic hierarchy process (AHP) to extract the exact weights of criteria which are then supplied to the PROMETHEE II method to rank various alternatives. The PROMETHEE II method is also extended to work with multi criteria group decision making problem with 2-tuple linguistic information. A prototype example is presented to illustrate the practicability of the proposed method.
