Abstract:By analyzing the status quo of prefabricated building management, it is found that there is a lack of standardization management, high cost, technical lag, and lack of professional talents in China's prefabricated building management. In order to solve these shortcomings, the lean management idea is applied to the entire life cycle of the prefabricated building management, and the standardized management standard process is used to optimize and standardize the prefabricated building management. Then, the lean management and the intelligent management are integrated. The intelligent management system of assembly-based building based on lean management is constructed. The framework system realizes management functions and application values from four aspects: user layer, application layer, intelligent management platform and data layer.
