INFLUENCE DEGREE ANALYZER, INFLUENCE DEGREE ANALYSIS METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an influence degree analyzer, etc. that are capable of more accurately analyzing an influence degree associated with a change in processing.SOLUTION: A dependency relationship acquisition part 410 acquires a dependency degree between multiple software components composing software in the software components, on the basis of a dependency frequency between the software components. A weighted dependency degree calculation part 420 calculates a weighted dependency degree between the software components by applying a weight, which is stored in a weight table 710 for storing a weight showing a characteristic of each software component, to the acquired dependency degree, with respect to each software component. A weighted DSM generation part 430 generates a weighted DSM, on the basis of the weighted dependency degree between the software components, with respect to the number of weighted dependency degrees between the software components calculated. An influence range extraction part 440 extracts an influence range associated with a change in the software, on the basis of the weighted DSM generated.
