Application of Fuzzy Topsis and Ahp Method in Evaluating Vehicle Roadworthiness Performance

Abstract

Roadworthiness itself can be achieved in a combination of two ways, by ‘Keep Vehicles Roadworthy’ and by ‘Produce Roadworthy Vehicles’. One can not keep a vehicle roadworthy, if it is not produced to be and to remain roadworthy. The other way around is that one doesn’t need to produce a roadworthy vehicle, if no one keeps it roadworthy. First, 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 14 indicators are firstly established. Optimal MCDM method i.e. fuzzy TOPSIS (The Technique for Order of Preference by Similarity to Ideal Solution) 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 fuzzy TOPSIS method to combine the vehicle roadworthiness indicators into one overall index. The results demonstrate the engineering practicability and effectiveness of AHP and TOPSIS method in vehicle roadworthiness evaluation also importance of the weights on the various indicators are being illustrated.
