    Multi-criteria Decision-making Approach for Selecting a Bridge Superstructure Construction Method
    (Springer Science and Business Media Deutschland GmbH, 2021) Upadhya, P.R.; Das, M.S.; Das, B.B.
    Selection of an effective construction method of bridge superstructure is critical to the success of the bridge project. Multiple criteria and the relative importance among them are involved in the process of decision-making. These criteria and their relative importance lead to vague and complex situation in the selection process. In order to tackle this complex situation, a mathematical methodology is required. Analytical Hierarchy Process (AHP) is a popular method that is used for solving Multi-Criteria Decision-Making (MCDM) problems. Every construction method of bridge superstructure has its own advantages and disadvantages. The challenge is to select the correct one for the prevailing circumstances. In this paper, the different methods of bridge construction are explained and are compared using their advantages, disadvantages and their suitability to different criteria and constraints associated with a bridge construction. The criteria weights and priorities are collected from experienced professionals of different point of view, i.e. Client, Designer and Contractor using questionnaire survey. Using this comparison, a decision support model is developed along with suitability ranking using AHP in order to simplify the process of selection of the appropriate method of bridge superstructure construction. © 2021, Springer Nature Singapore Pte Ltd.

    India Post Service Facility Layout Design Selection and Evaluation Using MCDM Approach
    (Springer Science and Business Media Deutschland GmbH, 2023) Vadivel, S.M.; Sanjai, S.; Siri, S.; Sequeira, A.H.
    This study uses the AHP technique to assess and choose the best facility layout based on technical practices, work environment, and ergonomics factors. This study will be beneficial in determining ways to improve operational performance in light of facility layout changes. We initially developed six logical layouts based on the field survey, which were approved by all shop floor staff, managers, and postal administrations to be evaluated under production performance layout schemes. Six alternative layouts, three performance criteria, and 13 sub-criteria were taken into consideration in this Facility Layout Design (FLD) problem. The analysis of the FLD in shop floor postal layouts yielded amazing results. This empirical investigation was conducted in India's southernmost National Sorting Hub (NSH) Mysore, Karnataka. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

    Modular Kitchen Layout Design Using AHP Method – An Indian Case Perspective
    (Springer Science and Business Media Deutschland GmbH, 2024) Vadivel, S.M.; Suganya, P.; Devanathan, C.; Sequeira, A.H.; Abhinav, A.
    This study uses the AHP technique to assess and choose the best facility layout based on cooking practices, work environment, and ergonomics (anthropometric) factors. This study will be beneficial in determining ways to minimize the cooking time in light of facility layout changes. We initially developed four logical layouts based on the survey, which were approved by all family members, neighbors, relations, friends, and working women in the apartment to be evaluated under various performance layout schemes. Four alternative layouts, three performance criteria were taken into consideration in this Facility Layout Design (FLD) problem. The analysis of the FLD was conducted in Park Avenue, Vijay Shanthi apartments, Chennai, Southern India. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.
