Change field 'Maximum Utilization in Percent' - TM

Hello Guys,

I have a small request to change the logic(how the value is calculated) for the 'Maximum Utilization in Percent' field from TM system. This field appear when I display a Freight Order .I will attach a print screen.

Can you tell me exactly where the value for this field is calculated? class/method.?

Thanks a lot.
