Abstract: There is a high level of variation in the results of influence of technical defects on accidents. For sure, vehicle roadworthiness plays a significant role in vehicle safety. This study proposes fuzzy AHP (Analytic Hierarchy Process) method to gain real values for the vehicle roadworthiness indicators. Within the proposed methodology, a decision group and vehicle roadworthiness framework containing 6 indicators are firstly established.
Optimal MCDM (Multi-Criteria Decision Making) method i.e. DEA (Data Envelopment Analysis) method was chosen for the evaluation of vehicle roadworthiness performance of motor vehicles depending on their condition and that assessment is presented through Vehicle Roadworthiness Performance Index - VRWPI of a motor vehicle in operation. This study also proposes DEA method to combine the vehicle condition indicators into one overall index. In the research 6 indicators are taken into consideration and in the next part of the paper will be made aggregation of indicators into one Composed Indicator i.e. VRWPI. The results demonstrate the engineering practicability and effectiveness of AHP and DEA method in vehicle roadworthiness evaluation also importance of the weights on the various indicators are being illustrated.
