In the model I have two problems, the first is that when Queue2 reaches a minimum of 25 pieces, the input port must be opened and Operator1 must start filling the Queue again until reaching 100 pieces and so on.
The other problem is that in Queue3 a batch of 50 is formed, when this happens an operator must take that batch to Queue4 and when another batch is put together in Queue3 another operator must go different from the first one and so on until returning to operator1. The problem I have is that all three operators go at the same time every time a batch is formed.
Could you help me solve this problem? Thank you very much.
