The parsimonious covering theory applied for communication equipment malfunction

Abstract

The article mainly applies parsimonious covering theory for the reasoning of communication equipment fault diagnosis and puts forward a kind of arithmetic which is suitable to communication equipment fault diagnosis on the basis of the parsimonious covering theory. In addition, it establishes an applicable model for fault diagnosis. The model can control the quantity of the hypothesis which is built through the arithmetic by selecting a corresponding parsimonious principle. The parsimonious principle results in adjusting contradiction dynamically between precision and efficiency during fault diagnosis, whose purpose is to make the model satisfy different diagnosis requirements.
