The invention discloses a
software quality evaluation method based on dependency chain quality conduction, relates to the technical field of
software quality evaluation, and is used for solving the problem that quality conduction between
software is difficult to quantify. According to the method, the dependency chain graph covering the component dependency relationship, the version pedigree and the quality index is constructed, the evidence reliability
label and the
license list are combined, the target component and the conduction path which do not meet the quality evaluation threshold value are accurately recognized, the
semantic mapping of the target component and the
business function domain is constructed, and in the path conduction analysis stage, the quality of the target component is analyzed. A constraint propagation and causal checking mechanism is introduced, influence is transmitted layer by layer, a real path and an interference path are automatically identified, a comprehensive
quality measurement item and a quality grade
label of a target component are generated, when evaluation is not met, an upgrading, replacing, isolating or
rollback scheme is automatically constructed, compatibility, time window and test influence of the scheme are evaluated, and a test result is obtained. And a closed-loop repair path and a treatment guide are output, so that the response efficiency and decision-making reasonability of the
software quality problem are improved.
