    Tamilnadu Omnibus Travels Evaluation Using TOPSIS and Fuzzy TOPSIS Methods
    (Springer Science and Business Media Deutschland GmbH, 2022) Vadivel, S.M.; Sequeira, A.H.; Jauhar, S.K.; Chandana, V.
    This research uses an effective fuzzy multi-criteria method to evaluate the performance of eight omnibus operators in Tamilnadu, India’s southernmost state (MA). The data was gathered from passengers (regular travelers) and the management of omnibus travel operators. Passengers provided qualitative data, while management offered quantitative data. To estimate the omnibus travels effectiveness, the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) technique and Fuzzy TOPSIS were employed to analyze the subjective assessments of both quantitative and qualitative data. Using linguistic concepts, the subjectiveness and inaccuracy of the performance assessment methods are expressed as fuzzy numbers. Traditionally, fuzzy MA models are often used to find the degree of possibility of an alternative of each attribute and sub-attributes to avoid complicated and inaccurate comparisons of fuzzy numbers. Then, grounded on the fuzzy techniques, it is converted into a weighted fuzzy performance index for each alternative. This technique is computationally efficient, and the principles behind it are basic and straightforward to comprehend. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

    Application of WASPAS Method for the Evaluation of Tamil Nadu Private Travels
    (Springer Science and Business Media Deutschland GmbH, 2023) Vadivel, S.M.; Sequeira, A.H.; Shetty, D.S.; Chandana, V.
    The most important and discussion topic is providing a sustainable service to customer in satisfaction on transportation facilities. Tamil NÄ du government has taken much initiatives to introduce more buses, trains in order to satisfy the customers while travelling. Tamil NÄ du (TN) has a huge population and people are expecting more facilities from TN government. Hence, in addition, Private bus travels came into that place to provide customers has better service. This paper aims to assess the performance of eight private bus travels passengers transport company in Tamil Nadu, Chennai. The performance data have been collected from both managers and frequent travelling passengers. The quantitative data collected from travels managers whereas qualitative data collected from passengers. These quantitative and qualitative have been analyzed with WASPAS a MCDM techniques. A novel MCDM technique known as WASPAS (Weighted Aggregated Sum Product Assessment) proposed in this study. The overall systematic algorithm for determining the best private bus travels company has been illustrated in step-by-step basis for further enhancement. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
