Abstract

A maintenance plan formulation system formulates a plan for maintaining an industrial machine used to conduct a specific operation. The maintenance plan formulation system includes first measuring means, second measuring means, and a maintenance plan formulation device. The first measuring means measures a value of information which varies by causing the industrial machine to operate for a specific job. The second measuring means measures a value of information which varies by causing the industrial machine to operate for a job other than the specific job. The maintenance plan formulation device formulates a plan for maintaining the industrial machine on the basis of the values of information measured by the first measuring means and the second measuring means.
