Brief
There was a mistake in the previous spec in which we modified duration calculations. The effective time cunsuption term was not well defined.
The current algorithms that calculates effective time consuption should only by used now for internal calculations of operations start and stop dates.
We remove this value from the GUI and reports of calculations and replace it with other better defined values.

Algorithms (Operations Work Time)
Operations work time = Cycle time * Numer of cycles needed
if include setup time then: Operations work time += Setup time * Number of workstations
if include additional time them: Operations work time += Additional time * Number of workstations
Operations machine work time = Operations work time * Machine utilization
Operations labor work time = Operations work time * Labor utilization
Order machine work time = SUM(Operations machine work time)
Order labor work time = SUM(Operations labor work time)
Same algorithm should be used in:
- cost calculations
- planned values in production balacne
The 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.
