In order to develop high quality products with lower cost and in a shorter time according to the conventional methods, Concurrent Engineering techniques should be applied on projects. Concurrent Engineering discipline requires a collaborative way of working of relevant departments in a factory. With a view to manage all product data collaboratively and to give related information to different departments, product structure should be constituted in a proper way by leading of Concurrent Engineering Department.In this paper, definition and content of product structure are explained. Product structure content is detailed regarding to aircraft structure which has different sections including all type of detailed parts like harness, equipment and structural parts. Moreover, management of product structure in lifecycle of an aircraft is considered. This topic is studied by examining different phases of an aircraft lifecycle in which the concept of product structure is explained. Furthermore, importance of using PLM (Product Lifecycle Management) tools for management of product structure is mentioned. With the help of PLM tools usage, management of software in product structure is studied by different methods. Advantages and disadvantages of these methods are examined and the most efficient method is proposed for software management.
