Connect data across machines and process steps to identify differences in standby, idle running, and energy use per item.
Start with a measurable problem
Select equipment or a system, compile operating hours, production output, and existing energy data, then confirm measurement points and the observation period.
Establish consistent comparison conditions
Products, loads, shifts, and environmental conditions can all affect energy use. Analysis and improvement verification need to retain the relevant production context.
Turn the question into a measurement scope
Organize energy and output by equipment, process and product batch. Consider changeovers, waiting and product mix. The international footwear simulation illustrates the method; operational analysis still requires site data.
