Research on the Product Breakdown Structure and Management Technology of Civil Aircraft

Civil aircraft is a high-complex and giant product.In order to accurately define this giant product and capture critical construct information of aircraft,and be convenient for division design,manufacture and assembly of product,product breakdown is needed to form a hierarchical product structure.Related definitions and concepts for building modular product structure are introduced.The meaning of product breakdown is demonstrated.Three different breakdown manners,and three product structures generated by these breakdown manners are studied.Based on the three product structures,the aim of effectively managing aircraft definition,design and assembly and aircraft configuration can be achieved.
