Subjective evaluation of automobile power performance based on RA-AHP

The primary objectives of this work were to devise an effective subjective evaluation method for automobile power performance based on regression analysis combined with the analytic hierarchy process (RA-AHP) and to propose a reliable, convenient approach for establishing an evaluation system for automobile power performance. To validate this method, four vehicles were selected, and 30 drivers completed a test drive on a selected route. A five-level Likert questionnaire was designed to subjectively evaluate automobile power performance. The test data were then compiled and used to establish an evaluation system based on the RA-AHP method, and the results from the evaluation system were compared with the vehicle sequence results from the drivers. The comparison showed that the results were the same and thus verified the feasibility of the RA-AHP method. This method is suitable for automobile companies to establish a subjective evaluation system of automobile power performance and can also be used in other fields to build a comprehensive evaluation system.
