PDM covers the entire life cycle of a product design, manufacture, and support. In particular,
maintenance is one of the important aspects. On the basis of maintenance task identifications generation
logic, PDM is mainly to provide product configuration data, including aircraft type, structure or systems
module, product information such as EBOM parts list, by means of mapping stratified to maintenance
mission, forming framework hierarchy tree of task logic structure, for different levels of nodes of the
tasks tree, provide components such as information, image etc. metadata. Figure 1 shows the hierarchical
mapping relationship logically.
