Production system hierarchical model

I n the era of Industry 4.0 , for the manufacturing, everything is connected thanks to the continuous development of automatic control and advanced sensor technology, and put forward a concept of ‘ Digital Factory ’ which uses digital technology for communications and to operate the manufacturing process. we modeling, By this way , we can fully monitor, control and optimize all the production variables in the manufacturing system in realtime. In this article, we introduce a practical industrial case, wh ich is the production of corncob powder for fuel. The whole production system transfers the raw materials corncobs into powder. Then we will develop a hierarchical production system model and apply this model to our practical case.
