An assembly process and quality check integrated product type assembly confi guration data network model is proposed to formalize interrelationship among engine, assembly task, assembly process, assembly procedure and check items. An engine assembly confi guration data network model is suggested. It can be used not only to describe instance relationship between engines and product type assembly configuration data templates, but also to maintain engine assembly confi guration after component exchange. Correspondent searching algorithms are designed to compare assembly confi guration between engines, and to output procedure and check items mixed onspot process guide card content dynamically.
