A rule acquisition method for civil aircraft maintenance task based on similarity rough set theory

In this paper, we put forward a kind of civil aircraft maintenance task determination methods based on similarity rough set (SRS) theory to handle the situation of lacking baseline aircraft at present. A rule gaining principle for civil aircraft maintenance task using maintenance experience of similar aircraft is described, and the acquisition method and detailed steps were presented. The test results indicate that the method is feasible. It not only remedies the information lose question that was brought from the classical rough set data dispersion, but also offers efficient decision-making for maintenance task of the civil aircraft in research.
