► The paper addresses the ranking inconsistency problem of fuzzy group MCDM. ► 18 methods are developed as an illustration to solve the general fuzzy group MCDM problem. ► A new approach is developed to select the MCDM method that best reflects the decision makers' preferences. ► An empirical study on the green bus fuel technology selection problem is conducted. ► The approach is applicable to large-scale multicriteria group decision problems with inconsistent ranking outcomes.
