Resource configuration change planning system and resource configuration change planning method

摘要

A system includes a first processing unit that executes a first planning algorithm to evaluate a migration destination resource based on a difference between performance of a migration target resource and reference performance and output a first solution as a migration destination resource state string that indicates a configuration and performance of the migration destination resource that is evaluated as a migration destination, a second processing unit that executes a second planning algorithm to output a second solution according to a mathematical programming method as the migration destination resource state string for the evaluated migration destination resource and uses the first solution to correct the second solution, and a third processing unit that outputs, between the first solution satisfying a time limit and the corrected second solution, a solution in which quality of the resource configuration change plan is estimated and an evaluation value of the plan meets a condition.
