Sincerely, Nguyen Le Thien Phuc ii SUMMARY OF MASTER’S THESIS The thesis "Tower Crane Layout Planning for High-Rise Construction Using Multi- Objective Colliding Bodies Optimization" proposes a new approach to optimize tower crane layout planning (TCLP) in high-rise construction projects. The research focuses on using metaheuristics and multi-objective optimization techniques to solve the complex and dynamic problem of TCLP. The literature review provides an overview of TCLP methods and techniques in high-rise construction, highlighting the limitations and challenges of traditional approaches. The review also discusses the use of metaheuristics and multi-objective optimization in TCLP, emphasizing the potential benefits of these techniques in improving the efficiency and effectiveness of TCLP.
The research methodology involves the development of a colliding bodies optimization (CBO) algorithm that integrates multiple objectives and constraints into the TCLP problem. The algorithm is tested and validated using a high-rise construction project case study in Ho Chi Minh City, Vietnam. The results demonstrate the effectiveness of the CBO algorithm in generating optimal TCLP solutions that minimize the total distance traveled by tower cranes, minimize the total operation cost, and minimize the collision risk between tower cranes and other construction elements. The thesis contributes to advancing TCLP research by proposing a novel approach that integrates metaheuristics and multi- objective optimization techniques to solve the complex and dynamic problem of TCLP in high-rise construction projects.
The proposed approach can improve the efficiency and effectiveness of TCLP, reduce construction time and cost, and enhance safety and productivity in high-rise construction projects.
