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 minority with standardization, mass production, and customization characteristics in the production process of the production line. Therefore, this integrated project attempts to introduce the concept of Industry 4.0 to the operation process of the production line in steel structure factory, and applies Information Technology to research and develop related technologies to fulfill it for the production and management of steel structure factory. Based on the concept of cyber-physical integration, the virtual BIM component model is used to aid the actual production of steel structure components, and then advanced technologies such as Internet of Things (IoT), mobile computing, Big data analytics, system simulation, optimization, 3D visualization, etc., are further introduced in order to achieve automation and intellectualization for the production and management operations of steel structure factory. Based on the production model by using virtual BIM component model to aid the manufacturing of real component as a common basis, the cooperation framework of this integrated project is divided into three sub-projects. Based on the investigators’ expertise, the overall goal of achieving the Industrial 4.0 for steel structure factory is divided into three parallel technology application aspects to research. Three sub-projects will support and integrate with each other to achieve the overall goal of the integrated project. The project integration framework is as follows. First, sub-project one will develop BIM-based cyber-physical integration model for production operation as the foundation. Based on this foundation, sub-project one will further apply IoT and Big Data technologies in the production line to gradually establish a basic system architecture of Industry 4.0 for steel structure factory. This basic structure consists of data source layer, data management layer, and data application layer. Meanwhile, on the foundation of BIM-based information digitization, sub-project two and sub-project three will apply 3D visualization technology, as well as system simulation and optimization technologies respectively on the data application layer of this structure to develop sub-modules or subsystems for aiding various production and management operations of steel structure factory, thus the goals of automation and intellectualization will be further achieved.建築資訊模型工業4.0鋼構廠物聯網雲端運算大數據分析最佳化視 覺化BIMIndustrial 4.0steel structure factoryInternet of ThingsCloud ComputingBig data analyticsOptimizationVisualization
