The increasing population far exceeds the limited supply of transport infrastructure and services. Mostly, traveling on a public bus and train services are overcrowded, undependable, slow, inconvenient, uncoordinated, and dangerous. Tamilnadu sub-urban desperately needs to improve and expand private transportation services to improve passengers’ satisfaction. In this paper, we have presented a multi-criteria decision-making approach for selecting the best private bus operators in Tamilnadu, the southern part of India. The evaluation has been made based on six criteria, twenty-eight sub-criteria, and eight private bus operators as alternatives. © 2020, Springer Nature Singapore Pte Ltd.Item 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.Item Indian Postal Service Quality Assessment Using Graph Theoretic Approach – A Quantitative Decision-Making Tool(Springer Science and Business Media Deutschland GmbH, 2023) Vadivel, S.M.; Sequeira, A.H.; Jauhar, S.K.This research intends to examine the Service Quality (SQ) factors in mail service operations conducted at National Sorting Hub (NSH), Mangalore, Karnataka state, Southern India. In the postal service industry, measuring SQ performance in mail service operations is a major challenge. So, this paper attempts to explore the positive effect of postal SQ factors on Customer Satisfaction (CS) with the data collected from employees (n = 148) to the Indian postal service. Further, to quantify the significance of SQ factors in gaining customer satisfaction, this study has used Graph-Theoretic approach technique. Results established same priority index to the SQ factors such as Human service delivery (Rank 1), Core service (Rank 2), and Systemization (Rank 3). The results indicate that the postal service industry should concentrate more on these factors to enhance their customer satisfaction. Further, the study employs the operating empirical model which is sparsely used in Indian domain. Furthermore, this research aids the SQ in designing and developing the necessary aspects to improve the CS in various service sectors. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.Item 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.
