Operations labor and machine work time

Abstract operations work time = Cycle time * Numer of operations cycles needed in order

if include setup time then:Operations  Abstract operations work time += Setup time * Number of workstations

if include additional time them:Operations  Abstract operations work time += Additional time * Number of workstations

Operations machine work time =Operations  Abstract operations work time * Machine utilization

Operations labor work time =Operations  Abstract operations work time * Labor utilization

The Operations The Abstract operations work time is a very abstract value and should not be show to the user in any scenario. Only the machine work time and labor work time make perfect sense for the user.

Operations start and end dates

Operations start date = if

• has no children operations then
  • Operations start date = Order start date
• else
  • Operations start date = MAX(Child operations block end date)

Operations duration time = if

• not Divisible cycle timethen

Operations block end date = if

• Next operation after type == Produced allthen
  • Operations block end date =
