PROBLEM TO BE SOLVED: To allow an optimum scenario to be selected based on the past execution results when performing work such as moving an object held using a robot.SOLUTION: First execution information is acquired which includes a plurality of execution logs in which scenarios executed by a robot, a selected value of a first parameter specifying the scenarios and execution results of the scenarios are related to one another. Instruction information is acquired which includes the content of a target work executed by the robot and a selected value of a second parameter specifying the target work. From the first execution information, an execution log is extracted, as second execution information, in which the content of the work shown by the scenarios is the same as the target work and the selected value of the first parameter is similar to the selected value of the second parameter. From the scenarios included in the execution log of the second execution information, a scenario optimum to the target work is selected and the selected scenario is outputted.
