I want to simulate pull process.
I have two works processes (#2 and #3 in the picture) and conveyor between them.
I want to have works process releasing component ONLY when the next station is empty/ready.
Currently, Works process #2 releases component when the task is ready but works process #3 is not ready, causing WIP on the conveyor.
I know that solution should be easy, maybe signal or if statement but I have not managed to solve this.
Thanks for advance.
