Abstract

The invention provides an equipment testability strategy optimization method and device, and the method comprises the steps of obtaining a test population which comprises a plurality of test sets for testing equipment; determining the test cost, the basic reliability cost and the testability performance benefit of the equipment based on the test population; taking the test cost and the basic reliability cost as first constraint parameters, and taking the testability performance benefit as a first test index to construct a first testability optimization model; and / or, taking the test cost, the basic reliability cost and the testability performance benefit as second constraint parameters, and taking the equipment comprehensive benefit as a second test index to construct a second testability optimization model; and performing testability strategy optimization calculation by adopting a fitness function based on the first testability optimization model and the second testability optimization model. According to the invention, the problems of single optimization target and easiness in falling into local convergence in the existing equipment testability optimization process in related technologies are solved.

Description

technical field [0001] The present application relates to the technical field of testability optimization, in particular to a method and device for equipment testability strategy optimization. Background technique [0002] For complex electronic systems, such as radar equipment, it is also necessary to select appropriate test nodes and test parameters for its testing and diagnosis. Due to the complex structure of the system, the relationship between faults, nodes and test parameters is difficult to obtain through mathematical derivation or simulation. Correlation model, research optimization strategy based on correlation model. In addition, testability optimization design is a process that comprehensively considers function, performance and reliability constraints. It is necessary to consider the trade-off and optimization of testability design from an overall perspective. Radar equipment can adopt an optimization strategy based on combined costs. [0003] Most of the exis...
