(Springer Science and Business Media Deutschland GmbH, 2024) Vadivel, S.M.; Asuvaitha, A.; Rea, R.S.C.; Veeraraghavan, R.; Sequeira, A.H.
For an organization in a manufacturing industry to be able to sustain itself in a competitive environment, the purchasing process plays an important role. It is the procurement departmentâ€™s responsibility to select the most desirable vendors and periodically evaluate their vendor performance in order to retain them. This study, Development and Evaluation of Vendor Analysis in TUV, deals with the process of assessing a companyâ€™s relationships with its suppliers and vendors, analyzing their effectiveness, and making changes if necessary. Vendor analysis is a critical and complex component of any business that relies on third-party providers to obtain materials or services based on several agreed-upon and contractual Key Performance Indicators (KPIs), such as the vendorâ€™s infrastructure, product quality, delivery, cost, housekeeping, availability of qualified personnel, record of standard availability, and financial capability. Multi-criterion decision-making (MCDM) techniques are used to handle these complexities, allowing consistent and effective decision-making and the selection of the best suitable supplier. This study utilizes the Analytic Hierarchy Process (AHP) to evaluate suppliers and select the most suitable vendors. By understanding vendor analysis and its importance, businesses can create strong partnerships that benefit both parties.

(Springer, 2022) Vadivel, S.M.; Sequeira, A.H.; Sakkariyas, R.R.; Boobalan, K.
This paper aims to study the determinants of the Lean Service System (LSS) on the Operational Performance (OP) of India's mail service in the National Sorting Hub (NSH), Mangaluru, Karnataka, the southern part of India. Measuring the OP in mail service is a big challenge in the postal service industry. Hence, we have conducted a survey, and 150 usable data has measured the impact of Lean Service Practices (LSP), Lean Workplace Environment Practices (LWEP), and Lean Social Practices (LSoP) on the OP. The results are analyzed from the partial least square based structural equation modelling (PLS-SEM) with the support of R programming. The analysis shows that there is positive and significant impact of LSP (β = 0.380, p <.05), followed by LWEP (β = 0.281, p <.05), and LSoP (β = 0.266, p <.05) on OP. The practical effect of the findings of LSS are effectively implemented for enhancing the OP of the business. This research addresses the appropriate empirical model to test LSS in India's postal service industry, which is scant in the existing literature. Moreover, this study helps India Post to review its policy so as to sustain the effectiveness of Lean Service (LS) implementation. © 2021, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.

Interval Type-2 Fuzzy-Support Vector Regression in Representation of Uncertainty in a Non-linear System
(Springer Science and Business Media Deutschland GmbH, 2025) Umoh, U.; Eyoh, I.; Asuquo, D.; Vadivel, S.M.; Alimot, O.
Machine learning algorithms such as Support Vector Machine (SVM and Support Vector Regression (SVR) are faced with challenges when confronted with imprecise and noisy data, which can lead to less meaningful outcomes. This paper introduces Interval Type-2 Fuzzy Support Vector Regression (IT2FSVR) as a solution to address uncertainty in non-linear systems. By combining Interval Type-2 Fuzzy Sets (IT2FS) and SVR, the proposed method enhances performance in systems with high levels of noise and non-linearity. The integration of IT2F membership in SVR directly tackles uncertainty in prediction problems, enabling adaptive learning to varying inputs and improving generalization performance. To demonstrate the effectiveness of this approach, the authors tested the performance of IT2F-SVR using a dataset of cardiovascular disease patients. Experimental results demonstrate that IT2F-SVR effectively eliminates uncertainty and significantly improves the learning process, outperforming individual approaches when applied to the same dataset and achieving faster execution times compared to some alternatives, albeit taking more time than SVR.
