Because there is no standard and systematic protocol to follow, it is usually inefficient and time-consuming to apply the multi-dimensional graphic technology into the material procurement in construction projects. This research tended to apply lean procurement into the materials management and facilitate the procurement management to avoid the waste cause by inaccurate procurement. This research combined 3D images characteristics with lean procurement to create a procurement management model for project manager. The steps of building this model are: (a) Developing a graphical framework which is called Object Block Work Breakdown Structure (OBWBS) based on Work Breakdown Structure (WBS) (b) Decomposing the hierarchy structure of OBWBS to produce the smallest 3D graphical unit with relevant material properties (example: the information is needed by the bill of material, such as number and models, etc. ) (c) Constructing basic structure and implementation process of the database associate with graphic correlation of OBWBS and work relationship of WBS to achieve the goal of systematic procurement management. By applying the graphical database which consists of graphical components and material properties, project manager can easily realize the bill of material and other procurement information. Furthermore, establishing reusable template through accumulation of different projects data can provide construction companies with accurate calculation related to the procurement of materials on similar type of building, it be able to save a lot of time and cost of projects in the future.口試委員審定書 I謝 II要 IIIBSTRACT IV一章 緒論 1.1 研究動機 1.2 研究目的 2.3 研究範圍與限制 2.4 研究流程與方法 3.5 論文架構 4.6 小結 4二章 文獻回顧 6.1 精實管理 6.1.1 精實生產 6.1.2 精實思維 7.1.2.1 精實思維之源由 7.1.2.2 精實思維之五項原理 7.1.3 精實營建 9.1.3.1 營建工程相關浪費彙整 9.1.3.2 精實營建理論 10.1.4 精實採購流程 11.2 4D模型相關應用 14.2.1 4D模型 14.2.2 4D互動式資訊場 15.2.3 視覺化比較 17.2.4 圖檔資訊解析技術 19.2.4.1 以工作單元(Work Package)解析圖檔 19.2.4.2 以作業項目(Work item)解析圖檔 20.2.4.3 以工地管控解析圖檔 21.3 資料庫 22.3.1 資料庫之定義 22.3.2 資料庫主要形式 23.3.3 元件資料庫 25.3.3.1 建築元件資料庫 25.4 小結 26三章 圖形介面劃分及應用 27.1 專案分工結構圖解析 28.1.1 建築元件庫(Building component Library, BCL) 28.1.2 Work Package Model 30.2 劃分原則 31.2.1 WBS(Work Breakdown Structure) 31.2.2 OBWBS(Object Block Work Breakdown Structure) 32.2.3 RBS(Resource Breakdown Structure) 34.3 賦予圖塊資訊 35.3.1 賦予採購資訊 35.3.1.1 圖塊及材料名稱、屬性分類 36.3.2 圖塊編碼及位置 37.4 小結 37四章 圖形資料庫模組建立 38.1 資料庫建置流程 39.2 多維度圖形資料庫建置步驟 42.2.1 精實採購 42.2.2 ER-MODEL建置 45.2.3 資料庫模組整合 46.2.4 Microstation Triforma 47.2.5 Microsoft Access 49.3 圖形資料庫應用 51.3.1 情境模擬案例導入 52.3.1.1 案例介紹 52.3.1.2 3D圖檔分解 52.3.1.3 查詢介面應用 55.4 圖形資料庫問題與困難點 62.5 小結 63五章 結論與建議 64.1 結論 64.2 未來研究與建議 65考文獻 672600000 bytesapplication/pdfen-US多維度圖形WBS精實採購資料庫Multi-dimensional graphicslean procurementdatabase應用多維度圖形資料庫技術於精實採購之研究Application of multi-dimensional graphic database for lean procurementthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/187835/1/ntu-98-R96521710-1.pdf
