I have set the processing time of each station and the schedule source of each type, how do I set the SPT and ECD (FCFS, ready time), because my model has product reflow, it will be on the M1 machine There are item1=1, item1=3, item4=1, item4=5, and there will be item1=2, item2=2, item4=4 on M2, so how can they be ASC on the machine at the same time And then do the next station processing.
