Modification risk degree measurement system, modification risk degree measurement method and modification risk degree measurement program

摘要

A modification risk degree measurement system includes a central processing unit (CPU), a program storage unit, a data storage unit, an input unit performing a control instruction and data input and an output unit performing data output. The extracting module, influence range specifying module, influence degree determining module, risk degree calculating module and re-factoring module are incorporated in the CPU. The extracting module performs extraction processing, the influence range specifying module specifies the influence range, the influence degree determining module determines the influence degree, the risk degree calculating module calculates the risk degree from the influence range and the influence degree, and the re-factoring module provides assistance in re-factoring.
