Thank you very much!. STUDENT: PHẠM MINH HUY iii MASTER THESIS 2024 ABSTRACT Construction site layout (CSL) involves a multi-criteria approach to addressing site planning and design issues. Placing a set of predetermined facilities in suitable locations is challenging due to numerous possible alternatives. Given the high complexity of site layout problems, various metaheuristic-based algorithms have been developed to find solutions.
Previous metaheuristic methods, such as particle swarm optimization (PSO), genetic algorithm (GA), differential evolution (DE), and firefly algorithm (FA), aim to optimize problems but have their own limitations. To address these limitations, this study proposes a new hybrid meta-heuristic model called the Hybrid Model of Mountain Gazelle Optimizer (HMGO). This algorithm integrates the original MGO, EOBL, and TS methods. This hybrid approach leverages the strengths and mitigates the weaknesses of each algorithm, effectively solving discrete problems in the quadratic assignment problem (QAP) optimally.
Furthermore, the study compares the performance of HMGO with GA, MIP, and MMAS-GA algorithms in site facilities layout problems. The results demonstrate that HMGO is more effective than existing optimization algorithms in solving these problems. Additionally, the study applies the algorithm to a real construction site layout problem, proving its effectiveness in real-world scenarios. This research supports construction managers by combining the experiences and strengths of the HMGO algorithm to enhance work efficiency in real-world situations.
STUDENT: PHẠM MINH HUY iv MASTER THESIS 2024 TÓM TẮT Bố trí mặt bằng xây dựng (CSL) liên quan đến cách tiếp cận đa tiêu chí để giải quyết các vấn đề về quy hoạch và thiết kế công tr ờng. Việc đặt một tập hợp các c sở vật chất đã định sẵn vào các vị trí thích hợp là một thách thức do có nhiều ph ng án khác nhau. Với sự phức tạp cao của các vấn đề bố trí mặt bằng, các thuật toán dựa trên siêu heuristics đã đ ợc phát triển để tìm ra giải pháp. Các ph ng pháp siêu heuristics tr ớc đây nh tối u hóa bầy đàn (PSO), thuật toán di truyền (GA), tiến hóa vi phân (DE) và thuật toán đom đóm (FA) nhằm tối u hóa các vấn đề nh ng vẫn có những hạn chế riêng.
Ěể khắc phục những hạn chế này, nghiên cứu này đề xuất một mô hình siêu heuristics lai mới gọi là Mô hình Lai của Bộ Tối u Hóa Linh D ng Núi (HMGO). Thuật toán này tích hợp MGO gốc, EOBL và các ph ng pháp TS. Cách tiếp cận lai này tận dụng các điểm mạnh và giảm thiểu các điểm yếu của từng thuật toán, giải quyết hiệu quả các vấn đề rời rạc trong vấn đề bài toán gán vị trí (QAP) một cách tối u. H n nữa, nghiên cứu so sánh hiệu suất của HMGO với các thuật toán GA, MIP và MMAS-GA trong các vấn đề bố trí c sở vật chất.
Kết quả cho thấy HMGO hiệu quả h n so với các thuật toán tối u hóa hiện có trong việc giải quyết những vấn đề này. Ngoài ra, nghiên cứu áp dụng thuật toán vào một vấn đề bố trí mặt bằng xây dựng thực tế, chứng minh tính hiệu quả của nó trong các tình huống thực tế. Nghiên cứu này hỗ trợ các nhà quản lý xây dựng bằng cách kết hợp kinh nghiệm và điểm mạnh của thuật toán HMGO để nâng cao hiệu quả công việc trong các tình huống thực tế.
