Study on the Commercial Vehicle Safety Exiting Evaluation Based on the Fuzzy Interval Evaluation and Weighted Ranking

Abstract

In order to evaluate the safety exiting of the commercial vehicle from the transportation market before recalling the defective vehicles, the climatic conditions, road conditions, and the driver behavior were adopted as road testing factors. On the basis of group multi-criteria decision making and fuzzy analytical hierarchy process (AHP) method, the hierarchic fuzzy evaluation model was established, and a simplified scale method was adopted to generate the judgment matrices meeting the consistency checking. Fuzzy intervals of the safety exiting evaluation were ranked with total weighted values. An example was given, under this approach, show that the decision making process of the commercial vehicle safety exiting evaluation (CVSEE) was a systematic and practical method for the market exiting schemes selection.
