Abstract

A cost computation device (10) comprises: a code clone detection unit (101) which detects, as a code clone, a combination of identical or similar sites included within pre-modification source code of a system; a componentization level setting unit (102) which sets a level for assembling the detected sites as components; a post-modification source code estimation unit (103) which estimates post-modification source code which is obtained when carrying out componentization at the set level with respect to the pre-modification source code; and a cost computation unit (104) which computes a modification cost and a maintenance cost, based on the estimated post-modification source code, and according to a cost reference which defines methods for computing the modification cost and the maintenance cost with respect to updating the system.

Description

technical field [0001] The present invention relates to a cost calculation device and a cost calculation method for calculating costs required for modification and maintenance when updating a system, and to a computer-readable recording medium recording a program for achieving the same. Background technique [0002] In recent years, businesses have attempted to update the legacy systems they were using to new systems that work on open platforms. In this attempt, attention has been focused on developing various techniques for the new system to perform the same processing as the old system. These techniques are characterized in that source codes that realize execution of the same processing are generated based on source codes of legacy systems. Therefore, compared with conventional operations for system integration (SI), the number of operation processes in requirement definition and design can be reduced. This ultimately reduces the modification costs (costs associated with...
