Good morning, I have a process that consists of a source that sequentially generates 8 different products, and they pass to a conveyor belt where there are 4 operators on one side and 4 operators on the other, each operator is assigned a specific product and in turn the processing time is different for each one of them, these operators usually tend to accumulate products since their processing speed is slower than the speed at which the products arrive at their position. YOUR URGENT HELP WITH THIS!
