A hesitant fuzzy multiplicative Base-criterion multi-criteria group decision making method

Hesitant fuzzy sets have a unique characteristic that its basic element could manifest the assessment values of different decision makers on same option under certain criterion. Base-criterion method is very significant tool for calculating weights criteria in multiple decision-making. In this paper, we developed novel approach hesitant BCM based multiplicative preference relation group making. The base-comparison preferential criterion relative to other expressed as linguistic terms, which might be converted into elements (HMEs). HMEs are extended along length according attitude makers. Then normalized optimal calculated. may transferred crisp by employing score function. To illustrate applicability and suitability BCM, analyse transportation mode selection problem car environment. outcomes proposed model indicate highly consistent can yield appreciable ranking alternatives.
