Parallel Routings / Parallel Production
I have a scenario where Production is taking place in such a way that when 10 pieces of a say Material A are produced the processing for the next level i.e. Material B starts and so on. The issue is that the system schedules the order in such a way that when the entire order of Material A is produced only then the production of Material B starts while in actual the Material B starts after 10 units of Material A have been produced. The order quantity is 100, it takes 1 hour to produce 10 units of Material A and 1 hour to produce 10 units of Material B. The system calculates that it will take 20 hours to produce both A and B while in actuality it takes 11 hours.
My question is how can we make the system automatically schedule Production this way. We are using discrete manufacturing, stock level and transfer needs to take place between materials so we can not use collective orders.
