What are the "four rates" indicators for installation and maintenance?

This is a strange question. It has nothing to do with stocks. There should be very few people saying this at present. Changsha Tietong mentioned this four-dimensional installation rate when promoting its services to the outside world. Refers to the four rates for installing and maintaining facilities. They are:

First, carry out equipment hazard investigation activities to reduce the recurrence rate of faults.

The second is to strengthen the analysis of typical faults and reduce the fault reporting rate.

The third is closed-loop management and strengthening employee technical training to improve the timely rate of troubleshooting.

Fourth is performance-linked strict assessment to improve the timely rate of installation.

Did you classify the question wrongly?
