The most advanced of these FMS's consist of automated machines, equipment, and work- and tool-transport apparatus, all operating under computer control with minimal manual intervention. They contain all the production equipment and production process modules of the CIM system represented in Figure 1 of Chapter 1, as well as production control software and even a modicum of production planning software.

NC machine tools doing the same type and quantity of work. The integration had reduced the number of NC machines required by 52.6 percent, personnel required by 52.6 percent, floor space required by 42 percent, part throughput time by 25 percent, total production time by 52.6 percent, tooling cost by 30 percent, total annual costs by 24 percent, and capital investment costs (including all the additional supporting and peripheral equipment and software required to accomplish full integration)
