Abstract: To discuss the quantitative relationship between the complexity of structure assembly and the quality of assembly,the assembly complexity was redefined from two aspects: the objective complexity and subjective complexity.The framework of structure assembly complexity analysis was advanced with three dimensions which included product design complexity,assembly process complexity and assembly decision complexity.The corresponding predictive model for product defect rate was developed respectively to each of three dimensions.Structure assembly defect rate prediction model which considered the design complexity,assembly process complexity and decision-making complexity was given.As a case,the improvement for one crane boom assembly quality based on model and recommendations was given.The proposed model could be used as the monitoring management to forecast assembly quality,and could also be used as the basis for product design and process adjustment.

Key words: structure, assembly quality defect rate, prediction, assembly complexity, analytical framework
