Research of a concurrency classification based on fuzzy decision

A method to reach the Mutual Recognition of Community Opinion based on language estimation information and trapezoid fuzzy number is discussed with the method of group decision-making, which is based on natural language estimation information. With non-dimension disposal, the language estimation information is changed into trapezoid fuzzy number. After steps such like massing the fuzzy number and so on, general estimation values on schemes (trapezoid fuzzy number) given by groups. Then, give common understanding analysis and estimation on group minds. In the end, calculate and sort schemes according to the final result of group common decision-making. An example is given as a validation of this method that it will receive practical decision-making effect.
