Every process will have both ideal output value and actual output values. Ideally, a process should always produce the maximum possible output. The maximum possible output is determined by a variety of factors and is often influenced most significantly by manufacturer specifications. Many manufacturers specify a nameplate value for their equipment to indicate the highest capacity of a given piece of equipment under ideal operating conditions. Together, the nameplate values for the individual pieces of equipment can help you determine the nameplate value for the entire unit, which is the maximum production output for the process under ideal operating conditions.
After you have plotted your production data, you will want to draw a Nameplate Line on the Production Analysis Plot to indicate the ideal output. Meridium Enterprise APM will calculate the difference between the ideal output and your observed output values (represented by the Demonstrated Line) to determine your Efficiency/Utilization Losses.
It may not always be appropriate to use the manufacturer's nameplate value as the nameplate value for your process. The maximum production capacity based on manufacturers' specifications may be unrealistic if you intentionally operate under conditions that do not meet those specifications. For example, you may operate at a lower temperature due to environmental constraints. If you calculate your production losses based on an impossible goal, your losses may appear inflated. In this case, you may want to take these factors into account to determine a more realistic nameplate value: one that actually can be achieved.
