Item Metaheuristic for Optimize the India Speed Post Facility Layout Design and Operational Performance Based Sorting Layout Selection Using DEA Method(Springer Verlag service@springer.de, 2020) Vadivel, S.M.; Sequeira, A.H.; Jauhar, S.K.Adoption of feasible location science is gaining more interest in the field of Facility Layout Design (FLD) problems among working researchers group. Many methods such as MCDM, Heuristics and Intelligent approaches are available to solve the FLD problems. However in reality, finding the feasible facility layout selection is subject to management as well as performances oriented selections. Here in India, speed post mail processing service industry is facing tremendous challenges like tumbling demands due to low production concern, gloomy trend in technology advancement, and fierce private couriers’ competition. Hence, the highly competitive operational performance is of much concern and attention is focused towards the direction of facility location science. This paper aims to examine the challenges of sustainable operational performance oriented layout selection by Data Envelopment Analysis (DEA) and proposes a genetic algorithm (GA) related to intelligent based approach, for finding the optimal total facility layout cost for a hypothetical South Indian speed post service office layout. In this paper, we used multiple-criteria facility layout selection problem using mathematical model generated with Data Envelopment Analysis (DEA). © 2020, Springer Nature Switzerland AG.Item CNC Machine Shop Floor Facility Layout Design Using Genetic Algorithm(Springer, 2020) Vadivel, V.; Sequeira, A.H.; Jauhar, S.K.; Amirthagadeswaran, K.S.; Aravind Krishna, T.The facility layout is a well-planned process to assimilate equipment, human resources, and materials for processing a product most effectively. The facility layout problem (FLP) is an optimization problem that involves determining the shape and location of various departments within a facility, based on the inter-department distance and volume measures. CRAFT algorithm is one of the primary methods currently used for the optimization of facility layouts. The aim of this is analyzing and assessing various proposed layouts through this algorithm. The objective is to minimize the total layout cost. It depends on the material flow and distance between the departments. An attempt has also been made to optimize the layout through GA. © 2020, Springer Nature Singapore Pte Ltd.Item Application of Multi-criteria Decision-Making Method for the Evaluation of Tamilnadu Private Bus Companies(Springer, 2020) Vadivel, V.; Sequeira, A.H.; Jauhar, S.K.; Baskaran, R.; Robert Rajkumar, S.The rapid growth of Tamilnadu sub-urban population has put enormous efforts on all modes of transportation systems, particularly the bus transportation. 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.
