- the average information is the same type of construction machine S of the same type (the same type of construction machine S may be a hydraulic excavator (which may have the same bucket capacity) as an excavating machine, or a wheel loader as a loading machine). For example, it may be the reciprocal of the respective average value of the number of times of the fuel consumption deterioration operation that occurred in the same kind of construction machine.

Therefore, it can be determined that priority should be given to the guidance for the operation operation with poor fuel consumption (more frequent occurrences) than with other construction machines.
- the priority item determination unit 54 determines the fuel consumption deterioration driving operation for which guidance should be output according to a predetermined priority order. Specifically, for example, when the comparison values are the same, it is determined that the message is output with priority in the order of idling for a long time, E mode recommendation, travel partial recommendation, and hydraulic relief.
