encouragement, and participation, this study would not have been possible Firstly, I sincerely appreciate Assoc Prof Dr Do Tien Sy and Dr Bui Phuong Trinh They provided me with plenty of insightful comments, advice, and supervision, as well as supportive encouragement Moreover, I would like to give a great altitude to Dr Nguyen Thanh Viet, who had also supported and guided me to finish my thesis Sincere thanks to my friends and the professionals in Vietnam's construction industry who patiently and sincerely offered me numerous suggestions and their opinions during the data collection and interviews Without their assistance, this master's thesis would not have come to an end Last but not least, I want to express my sincere gratitude to my family for their support and love Throughout the course of my master's thesis, they never stopped supporting and encouraging me and never gave up on me iii ABSTRACT The improper management of materials during site activities is a crucial factor that has a negative impact on the performance of construction projects Materials management is problematic by shortages, supply delays, price fluctuations, damage, wastage, and a lack of storage space Numerous studies were conducted to identify the issue causing poor material management, and solutions were offered These solutions, however, only help to enhance a portion of the materials management In the grand scheme of things, improper detail procedure control prevents proper material management in the construction project Therefore, Lean tool and Value Stream Mapping (VSM) were brought in this thesis to answer the question The purpose of this thesis is to understand which activities are value-adding and nonvalue-adding to the current process and create a leaner and better material management The objective is to identify and reduce "waste" in value streams in order to increase the efficiency of a specific value stream in material management The study discovered the current construction material management procedure of construction projects/companies in Vietnam through interviews with experts in the field On the basis of the survey of the Case Study project, the thesis also discovered waste in the current process The thesis developed the project's material management process, evaluated the process time, and identified the source of waste by applying Lean tools to the actual Case study process The thesis used that information to identify the wasteful activities that needed to be stopped The thesis also utilized Revit and Amis accounting software to improve process in the perspective of saving more time, requiring fewer staff members, and becoming more professional The results of the thesis showed that by using the VSM tool, in the same actual project, if comparing with using the traditional process, the new material management time from the process of calculating volume, ordering (including making contracts), examining and accepting input materials and warehousing is reduced 16.9% of the initial total time More importantly, Value Added Time is now 50.6% of total time of the total material iv management process This means that the company can reduce costs, waste, and effectively use the company's human resources In other word, leaner processes will make it simpler to identify waste and quality problems, enhancing the productivity of material management in construction projects Moreover, the shortcomings of the previous material management procedure are studied, and the new procedure's application is verified This helps investors or companies have an objective view and easily accept new effective proposals As a result, production in general and material controlling in particular will be completed much faster and more efficiently, giving the company more flexibility to respond to shifting customer demands In lean production, there is always a more effective way to complete every task because a business must keep up with the changing market in order to satisfy these new customer demands Key words: Construction Material Management, Lean tools, Lean in Construction, Value Stream Mapping (VSM), Improvement,

vật liệu gặp nhiều vấn đề thiếu hụt, cung ứng chậm trễ, biến động giá cả, hư hỏng, lãng phí thiếu kho bãi Nhiều nghiên cứu thực để xác định vấn đề gây việc quản lý vật liệu giải pháp đưa Tuy nhiên, giải pháp giúp cải thiện phần cơng tác quản lý ngun vật liệu Nhìn chung, quy trình quản lý chi tiết khơng phù hợp ảnh hưởng tiêu cực đến việc quản lý vật liệu dự án xây dựng Vì vậy, cơng cụ Tinh gọn Sơ đồ dòng giá trị (VSM) đưa vào luận văn để trả lời câu hỏi Mục đích luận án để hiểu hoạt động mang lại giá trị không gia tăng giá trị cho quy trình tạo hệ thống quản lý vật liệu tinh gọn tốt Mục tiêu xác định giảm "lãng phí" dịng giá trị nhằm tăng hiệu quản lý vật chất Nghiên cứu tìm quy trình quản lý vật liệu xây dựng dự án/công ty xây dựng Việt Nam thông qua vấn chuyên gia lĩnh vực Trên sở khảo sát dự án, luận án phát lãng phí quy trình Luận án xây dựng quy trình quản lý nguyên vật liệu dự án, đánh giá thời gian thực công tác, xác định nguồn gốc lãng phí cách áp dụng cơng cụ Lean vào quy trình dự án thực tế Luận án sử dụng thơng tin để xác định hoạt động lãng phí cần phải chấm dứt Luận án sử dụng phần mềm kế toán Amis phần mềm thiết kế Revit để cải tiến quy trình theo hướng tiết kiệm thời gian hơn, nhân viên chuyên nghiệp Kết luận án cho thấy, với việc sử dụng công cụ VSM, cơng trình thực tế, so sánh với việc sử dụng quy trình truyền thống thời gian quản lý vật tư từ khâu tính khối lượng, đặt hàng (kể làm hợp đồng), kiểm tra, nghiệm thu đầu vào nguyên vật liệu nhập kho giảm 16,9% so với tổng thời gian ban đầu Quan trọng hơn, thời gian gia tăng giá trị chiếm 50,6% tổng thời gian tồn quy trình quản lý vật liệu Điều có nghĩa cơng ty giảm chi phí, lãng vi phí sử dụng hiệu nguồn nhân lực công ty Hơn nữa, thiếu sót quy trình quản lý vật liệu trước nghiên cứu ứng dụng quy
