INTRODUCTION Multi-criteria Decision Making (MCDA) Why we need MCDA? • Evaluation of multi-criterian situations using conventional approaches may be difficult. • It helps civil engineers make well-informed choices that lead to sustainable, cost effective, and socially responsible infrastructure development. It is the process of determining the best solution for given problem according to established criteria. 3 Applications of MCDA: Nowadays MCDA is using in almost all fields such as: • Medical Fields • Engineering Fields • Business Administration • Information Technology
INTRODUCTION Flow Chart of MCDA 4
INTRODUCTION Methods of MCDA There are different method for Multi-criteria decision analysis and here are the commonly used MCDM methods: 5 • Analytical Hierarchical Process (AHP) • Technique for order of preferences by similarity to ideal solution (TOPSIS) • Evaluation based on distance from average solution (EDAS) • Elimination and Choice Translating Reality (ELECTRE) • Vlekriterijumsko Kompromiseno Rangiranje (VIKOR)
LITERATURE REVIEW  Zafar, et al., (2022) Integrating technical-environmental-economical perspectives for optimizing rubber content in concrete by multi-criteria analysis  In technical perspective the performance of rubber crumb incorporated concrete was better.  The CO2 emissions and Cost were less for powder rubber incorporated concrete  Raw material conservation is better for rubber chip incorporated concrete  Finally, all perspectives were integrated, and a framework having 13 criteria and their weightage was evaluated by Entropy method. As a result, 5% rubber chip concrete showed top ranking. 6

LITERATURE REVIEW  Tosic, et al., (2015) Multicriteria optimization of natural and recycled aggregate concrete for structural use  For criteria ranking “equal importance” the alternative RAC-50 is the compromise solution.  In case of “environmental advantage” criteria ranking the compromise solution consists of two alternative (RAC 50 and RAC 100)  Under the “economical advantage” criteria ranking the compromise solutions are again two alternatives (RAC 50 and NAC 50).

PROBLEM STATEMENT 12  Multi-criteria decision analysis (MCDA) being a part of the curriculum across various department such as Architecture Engineering, Environmental Engineering and Mathematics etc. We observe need of the application of MCDA in Civil Engineering. This discrepancy raises concerns about the preparedness of Civil Engineering graduates to navigate complex decision making scenarios effectively.  This study proposes the development of user-friendly computer based tools in which a decision support system is developed to select the best alternative using different criteria based on the preferences of users.…………………….

    INTRODUCTION Multi-criteria Decision Making(MCDA) Why we need MCDA? • Evaluation of multi-criterian situations using conventional approaches may be difficult. • It helps civil engineers make well-informed choices that lead to sustainable, cost effective, and socially responsible infrastructure development. It is the process of determining the best solution for given problem according to established criteria. 3 Applications of MCDA: Nowadays MCDA is using in almost all fields such as: • Medical Fields • Engineering Fields • Business Administration • Information Technology

    INTRODUCTION Methods of MCDA Thereare different method for Multi-criteria decision analysis and here are the commonly used MCDM methods: 5 • Analytical Hierarchical Process (AHP) • Technique for order of preferences by similarity to ideal solution (TOPSIS) • Evaluation based on distance from average solution (EDAS) • Elimination and Choice Translating Reality (ELECTRE) • Vlekriterijumsko Kompromiseno Rangiranje (VIKOR)

    LITERATURE REVIEW  Zafar,et al., (2022) Integrating technical-environmental-economical perspectives for optimizing rubber content in concrete by multi-criteria analysis  In technical perspective the performance of rubber crumb incorporated concrete was better.  The CO2 emissions and Cost were less for powder rubber incorporated concrete  Raw material conservation is better for rubber chip incorporated concrete  Finally, all perspectives were integrated, and a framework having 13 criteria and their weightage was evaluated by Entropy method. As a result, 5% rubber chip concrete showed top ranking. 6

    PROBLEM STATEMENT 12  Multi-criteriadecision analysis (MCDA) being a part of the curriculum across various department such as Architecture Engineering, Environmental Engineering and Mathematics etc. We observe need of the application of MCDA in Civil Engineering. This discrepancy raises concerns about the preparedness of Civil Engineering graduates to navigate complex decision making scenarios effectively.  This study proposes the development of user-friendly computer based tools in which a decision support system is developed to select the best alternative using different criteria based on the preferences of users.…………………….
