We remove this value from the GUI and reports of calculations and replace it with other better defined values.

We should also review and correct out algorithms.

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.

Operation dates - calculated from orders start dane

Operations start date = if

• has no children operations then
  
  • Operations start date = Order start date
• else
  
  • Operations start date = MAX(Next operations start operation blocked to date calculated for children operations)

Operations duration time without nonworking time = Setup time + Additional time + if

...

Operation cycles on most used workstation = if

• not Divisible cycle time  then
  
  • + Cycle time * roundUp(Numer of cycles needed in order / Number of workstations)
• else
  
  • + Cycle time * (Numer of cycles needed in order / Number of workstations)

Operations duration time without nonworking time = Setup time + Additional time + Cycle time * Operation cycles on most used workstation

Operations duration time = Operations duration time without nonworking time distributed across working time of shifts

Operations end date = Operations start date + Operations duration time

Next operation after cycles = required number of cycles to produce Next operation after produced quantity

Next operation after cycles is only calculated if Next operation after type == Produced all

Next operations block duration without nonworking time = Operations start date + Setup time + if

...

operations after block date = if

• Next operation after type == Operation ended, then
  • = Operations end date
    
• Next operation after type == Produced specified quantity, then
  • = Operations start date + Next operations block duration

Next operation after cycles = if

• Next operation after produced quantity <= quantity of the operations main output product required in order
  
  • = required number of cycles to produce Next operation after produced quantity
• else
  
  • = required number of cycles to produce quantity of the operations main output product required in order

Next operation after cycles on most used workstation = if

• not Divisible cycle time  then
  
  • + Cycle time * = roundUp(Next operation after cycles / Number of workstations)
• else Operations duration time then
  
  • + Cycle time * (= Next operation after cycles / Number of workstations)

...

Next operation block duration without nonworking time = Setup time + Additional time + Cycle time + Next operation after cycles on most used workstation

Next operation block duration = Next operations operation block duration without nonworking time distributed across working time of shifts
Next operations start date = Operations start date + Next operations block

Order calculated end date = Operations end date of root operation

Operations duration distribution - from a given start date

Any type of duration time without nonworking time is independent from the time axis and does not take into account the the company is forking or not.

Only the duration time that takes this information into account is dependant from the operations starting date and the time axis context which indicated when the company is working or not.

Input data:

• Operations start date
• Operations duration time - or the Next operation block duration
