Synthesizing applications of FTA method in testability and reliability, research on optimizing method for diagnosis strategy of complicated electronic equipments based on FTA is taken systematically.

Testability analysis and fault diagnosis strategy design are important parts of testability design for system.

The definition and representation of multisignal model are introduced,then the optimum seeking method of fault detection test and fault isolation test,and the design method of diagnosis strategy on the single fault assumption are given.

Optimization method for diagnostic strategy with unreliable test;

Optimized diagnostic strategy generation with multivalued tests;

Based on this HEF,a suboptimal diagnostic strategy searchin.

Research on optimizing the fault diagnosis strategy of complex electronic equipments

The technique of artificial neural network (ANN) is applied to non-determinacy diagnostic reasoning of expert system (ES) in this paper.

A diagnostic reasoning mode based on causal network is proposed.

In this paper,we presented our approach for diagnostic reasoning and rule acquiring for chestnut diseases based on rough set theory,including data preprocessing,attribute reduction,rule acquisition,diagnostic reasoning,and so on.
