工業4.0為政府近年來積極推動的產業升級計畫，其主要概念是建構於虛實整合系統（Cyber-Physical System, CPS）之基礎上，以資訊系統（Information Technology, IT）為核心技術，並結合工廠既有操作技術（Operational Technology, OT）的融合系統，且以數據分析為基礎概念，研發打造「智慧化的工廠」；於營建產業之供應鏈中，具有標準化、大量生產、客製化等特性的生產作業流程並不多，鋼構廠為少數符合以上特性的供應商，具有標準作業流程之生產線，因此本研究以鋼構廠為課題，導入建築資訊模型（Building Information Model, BIM）改善既有的作業模式，將資訊以數位化、智慧化為目標，以追求最佳的生產效率與產品質量。
本研究將以BIM應用於鋼構廠生產製造之目標，研究BIM模型資訊之正確性、模型版本管理與模型資料擷取之自動化，使其輔助鋼構廠之構件管理與生產線製造之資訊提供，使用BIM軟體Tekla Structures，並利用其所提供之Tekla Open API開發系統外掛程式，將模型資訊的處理與分析自動化，建立BIM模型之正確性驗證程序與版次差異之管理，輔助相關作業人員針對BIM模型資訊以有效率的修正與審查，並以驗證後之BIM模型產生物料清單（Bill of Materials, BOM），提供資訊於鋼構構件生產製造，利用自動化之系統與功能模組，以達到減少人力資源與時間成本。

Industrial 4.0 is the industrial upgrading program which is actively promoted by the government in recent years. Its main concept is built on the Cyber-Physical System as the foundation and Information Technology as the core technology to integrate the existing Operational Technology of Factories. Industry 4.0 creates what has been called a "smart factory" based on data analysis. In construction industry, steel structure factory is the minority with standardization, mass production, and customization characteristics in the production process of the production line. Therefore, this study attempts to apply Industrial 4.0 concept on the production line of steel structure factory and adopt Building Information Model to improve existing working mode.
Based on the concept of using virtual component model to assist the manufacturing of real component, this study develops a web-based system to automate correctness check, version comparison, and data acquisition of BIM for steel structure by using Tekla Open API and web programming tools. The functional modules of the proposed system can assist operator to effectively check and revise BIM, review the differences between different versions of BIM, and generate a Bill of Materials (BOM) with the verified BIM to provide information for the manufacture of steel components. Such automation can reduce the cost of human resources and time.
