in our plant we have 3 packaging lines.
line 1 packs 1kg semolina bags
line 2 packs 0.5 kg semolina bags
line 3 packs 500 kg big bags
I created 3 work center, in the capacity they made me enter the kg per hour that the line can pack , I don’t know if this setting is correct ?
Ad example line 1 can pack 600 kg\h in the area tab I put as capacity 600
The line shift work is from 8 am to 5 pm without break
Your partner will be the best one to work through this with you.
That being said, I generally enter capacity as units of time. 8 am to 5 pm would be 9 hours. The run time (and other factors) will determine the Units produced per unit of time. If you need to produce 3600 kg, the system will calculate how much time is needed to complete that production run and reduce the WC capacity by that amount.

Capacity in BC is for Scheduling how many Orders you can do at the same time… and time available during the production shift.

Federico - An example of ‘capacity’ is you have 3 lines or machines that all run at the same rate. The Workcenter would be set with a capacity of 3.
Then you would setup under the Workcenter 3 machines to be used for scheduling.
The default routing for a product that requires one of the machines/lines would initially use the Workcenter simply because you do not know which Machine/Line it will be run on until the Prod Order is Released (the planner would update the Prod operation from the Workcenter to the correct Machine/line as part of Releasing the Prod Order to the floor)
An example using the above method - with our setup we have 24 hours available in the Workcenter (3x8).
A Prod Order requiring a total of 24 hours of run time would take 3 days selecting a Capacity of 1.
If you use a Capacity of 2 (meaning use 2 Machines/Lines) the Prod Order would be done in 12 hours
In your requirements you have 3 lines that do not have the same throughput. 3 Workcenters would be setup and the default Routing would identify where normally you run the product - I suspect you may decide to change ‘normal’ Workcenter if you are overloaded at times. The planner would change the default routing selecting an ‘alternate’ routing which is a slower line but the work would still get done in time.
The issue here is production gets the work done on time but the Financial team is wondering why processing costs are higher🙃 - if this happens a lot then it might indicate another faster line is needed.
Long winded response but wanted to give you an example of using capacity. You processing rate for each line can be reflected by your lot size on the operation route step.

Thank you for example. I set the capacity at 1 e not 600.
In our plant, before the packaging operation can begin, the semi-finished product that comes out of the oven must be deposited in a silo, that is, a silo that has a capacity of 40 quintals must first be filled. Can I put this silo filling time as a waiting time in the routing line of the product that is packaged?
Federico -
Wait time is using a 7x24 hour day meaning it is not looking at the calendar open time to calculate when available for the next operation which I do not think is what you want.
Move time would better serve you as it uses the Workcenter/Machine open time for the calculation. As always test and let us know your results.

Thank you for answer.
To calculate the move time based on the quantity capcity of silos in BC is there any tool or field?
