Labor Hours

If the Labor Requirements Are Per Oper-h and Per Equip option is checked then the labor demand of the operation can be interpreted as labor hours per operating hour and per equipment. Therefore when calculating the labor amount of an operation which is using multiple equipment units simultaneously (in parallel), then we must multiply the amount by the number of units.
