A clutch disk includes a hub area and a plurality of friction lining elements arranged in sequence in the circumferential direction relative to a clutch disk rotational axis, each providing at least part of an associated friction surface area. This optimization of equipment utilization minimizes equipment and direct utility costs per batch, as well as reduces the physical space and the associated utilities required to support manufacturing operations. One or more inputs are provided to receive a plurality of additives that are associated with the fluid, wherein actuators are employed by the processor to dispense the additives to the fluid. The agent application tests the user’s system for each problem description within a downloaded data structure from the expert system library.
