I am trying to make a mechanical component manufacturing plant model. In short part of the model from source1 one unfinished product is coming and reaching to processor1 and at the same time from other source2 a batch of 5 bolts is reaching to processor1 which I want to put on that product coming from source1.so total input in processor 1 is 6 as I will put all those 5 bolt on that product it will become one product and another operation will process on next processor. I am getting a problem every time processor1 is showing output as 6 instead of one. Is it possible to solve this issue by using labels? Other small query in my model is that if I give proper set up time and process time to combiner is it right that combiner can also process my product like processor do or I have to use processor after combiner to do operation. ?
