The application discloses a
software quality evaluation method based on a 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; the application constructs a dependency chain graph covering the dependency relationship of a component, a version pedigree and a quality index, combines evidence reliability labels and
license lists, accurately identifies target components and conduction paths that do not meet a quality evaluation threshold, and constructs
semantic mapping of the target components and a
business function domain; in a path conduction analysis stage, a constraint propagation and a causal checking mechanism are introduced, influences are transmitted layer by layer, real paths and interference paths are automatically identified, a comprehensive
quality measurement item and a
quality level label of the target components are generated, when the evaluation does not meet the requirement, an
upgrade, replacement, isolation or
rollback scheme is automatically constructed, compatibility, a time window and test influence are evaluated, a closed-loop repair path and disposal guidance are output, and the response efficiency and decision rationality of
software quality problems are improved.
