Research on the Standard System Framework of Industrialized Buildings Based on System Analysis Methodology

Industrialized construction as a new method can dramatically improve the quality of buildings and efficiency of construction. However, there are many barriers when we push to develop industrialized buildings. Fewer codes and standards that are available for modern methods of construction and absence of relevant quality assessment tools and accreditation, which are the main problems need to be solved. Analyzing the status of industrialized building system at home and abroad, this paper tries to build industrialized building standard system (IBSS) framework model that is based on the system analysis methodology and theory of standardization. Firstly, the standard system scope is cleared, which covers a whole life cycle of industrialized building from preliminary design to building dismantling and reuse. Then the objective of IBSS clarifies the object of standardization, providing a basis for the standard items generation. Meanwhile, through analyzing the difference and application of the topology structure of the standard system, a mixed standard system structure is built. It integrates the classification hierarchy structure, matrix structure, and sequence structure. Finally, each standard should find a unique position in the IBSS, so the attribution of standard items must be figure out and the six-dimension space of attribution of standard is born. The study will provide a framework and theoretical basis for further improvement of IBSS.
