Item A novel approach for operational performance based mail sorting facility layout selection using grey relational analysis: A case on India speed post service industry(Springer Verlag service@springer.de, 2020) Vadivel, S.M.; Sequeira, A.H.Facility layout design (FLD) comes under multi-objective problem which has a major impact on service or manufacturing industries performance. Facility layout design purpose is to streamline the work flow smoothly and increasing the production by reducing the material handling time. An attempt has been done on Grey Relational Analysis (GRA) in order to identify the feasible layout for the aids of operational performance. This FLD focuses on finding and eliminating the waste in the process flow and brings the comfortable workplace environment in order to attain the operational performance. The recommended approaches are demonstrated through practical applications in India speed post sorting facility layouts. Practical results are promising for incorporating optimal method for solving layout design problem. © Springer Nature Switzerland AG 2020.Item Applying simulation in lean service to enhance the operational system in Indian postal service industry(Springer, 2022) Vadivel, S.M.; Jauhar, S.K.; Sequeira, A.H.This paper aims to present an innovative approach to design a Lean Service System in the India Post service industry using the Simulation method to reduce the system’s complexity. Using logic and systematic building blocks, simulation models have been developed from lean service elements using the arena software and verified in Siemens Tecnomatix plant simulation suite. Simulation is used to replicate the real model, guide the future production system, and determine the optimal parameter values. Simulation studies have been divided into two perspectives, “before LS” and “after LS” through Value Stream Mapping (VSM). It has been found that there is a 9.62 percent enhancement in delivering articles per person. A real case of postal service internal operational performance has been taken for the study. This study is the first to combine Value Stream Mapping - Simulation (VSM-Sim) to simulate and optimize the mailing service operations’ operational performance parameters. © 2021, The Author(s), under exclusive licence to Springer Science+Business Media, LLC part of Springer Nature.Item Impact of lean service, workplace environment, and social practices on the operational performance of India post service industry(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.
