In a future release it is envisioned to replace the above model construct with a simpler and more intuitive representation as a resource.
In this example we have a production consisting of 5 subsequent steps. We model a (virtual) tool to control the level of work-in-progress across the operations 2 through 4: only 2 jobs are allowed simultaneously in this cell. You can think of this as a kanban card which we need to obtain when entering the cell, and which we release when leaving the cell.
Use the operation plan detail report to verify that the constraint is correctly respected. You’ll find that new operations at step 2 are only created at the moment when an operation at step 4 finishes (considering also working hours).
You can change the initial inventory of the kanban cards to see how it impacts the delivery performance. How many cards do you need at least to bring the lateness to its minimum? And can you explain that result?
