Dynamic Taxonomies Usage in the Context of Aeronautical Maintenance Processes to Increase the Effectiveness and the Efficiency of the Operations

摘要

The purpose of this work is to increase the effectiveness and the efficiency of the operations carried out during the activities in the aeronautical maintenance and transformation processes. In particular, we examine the Non-Routine Card Resolution Process. An NRC is document issued when a fault, not expected, detected during the maintenance/transformation operations, is found. Typically to describe a defect we need of the aircraft zone (MajorZone, Sub-MajorZone, Zone, etc.) and/or the system (ATA system) and/or the coordinates, the component (sometimes with the sub-component) and the kind of the defect with its attributes. We named this set of information Non-Routine Card. The costs and the efforts of the NRC management are of the same order of magnitude of the planned activity management (Job Card -^sJC). The process requires that corrective actions come from applicable technical documentation. There are many kinds of defects and technical documentation does not cover all possible cases. Often, we observed the operators refer to similar NRCs solved in the past.
