Embodiment Construction

[0057] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will be described in detail with reference to the accompanying drawings.

[0058] The invention proposes a construction method of a multi-level software fault diagnosis expert system, and the system constructed by the method can adopt a corresponding mechanism for diagnosis according to different types of faults. For the software faults that have occurred in the diagnosed object, the fault mechanism and possible fault manifestations are known, and relevant successful analysis experience is available. The shallow fault diagnosis subsystem can be used to perform similar matching reasoning through the case base to achieve rapid fault analysis. For unknown faults that occur in the diagnosed object, the fault mechanism and fault characterization are unknown in advance, and when there is no ready-to-use expert experience for reference, the f...

Abstract

A construction method for a multi-layer software fault diagnosis expert system includes the steps that 1, a lot of fault cases related to diagnosed software are collected; 2, in combination with a defect classification method for the software, a defect attribute classification model is constructed; 3, a software defect classification model is constructed and subjected to formalized description; 4, other fault attribute classification models suitable for the diagnosed object are constructed; 5, by the utilization of an F-CBR technology, cases of a fault case library are operated; 6, in combination with the F-CBR technology, a superficial layer fault subsystem is constructed; 7, concrete realization is carried out on the superficial layer fault system in combination with the F-CBR technology; 8, a deep-layer subsystem is constructed; 9, a deep-layer fault subsystem is constructed and realized; 10, connection between the superficial layer subsystem and the deep-layer subsystem is constructed, so that the data-sharing function of the fault case library is achieved. Through the steps, the multi-layer software fault diagnosis expert system is constructed, so that software fault diagnosis is completed.

Description

technical field [0001] The invention provides a construction method of a multi-level software fault diagnosis expert system, which relates to the realization of a multi-level software fault diagnosis expert system, and belongs to the fields of software reliability and software fault diagnosis. Background technique [0002] Expert system is an applied edge subject, its theoretical basis involves many disciplines, such as modern control theory, computer engineering, mathematical statistics, etc. or unmeasurable) and some of the variables show different characteristics from the normal state, find out the characteristic description of the fault defect, and classify it according to the defect, and further realize the inspection and prediction of the fault. [0003] As software becomes more and more complex, a software fault may be caused by a combination of multiple reasons, and the problem presented by the fault may also be caused by multiple phenomena. For this type of fault, ...
