MAINTENANCE COST ESTIMATION PROGRAM, MAINTENANCE COST ESTIMATION METHOD AND MAINTENANCE COST ESTIMATION DEVICE

摘要

PROBLEM TO BE SOLVED: To estimate the maintenance cost of a software product.

SOLUTION: An operation cost calculation part 110 calculates operation costs in the case of executing the maintenance of each module configuring a software product, and a product model preparation part 120 prepares the product model of the software product by analyzing the control flow and data flow of a module, and a maintenance point calculation part 130 calculates maintenance points for a maintenance request by using the operation costs and product model of each module. Also, a generalization maintenance point calculation part 140 calculates generalization maintenance points by setting the probability distribution Rdof the maintenance request of the module r as uniform 1/n.
