1 CIMS hierarchical control architecture American National Standards Institute (AMRF) automated manufacturing research and experimental base to CIMS using five hierarchical control architecture, as shown in Figure 21. Figure 1 steel pipe material computer sorting system structure diagram The figure is similar to the form of table expression, it has been widely discrete CIMS industry researchers accepted. The so-called hierarchical control (Hierarc
