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.
