Peak-to-Average Ratio

The multiple between peak daily or weekly order volume and average baseline volume, used to size automation systems and assess demand variability risk.

The peak-to-average ratio expresses how much higher order volume climbs at peak demand relative to a typical operating period. As a hypothetical arithmetic example, 10,000 daily orders on average and 35,000 at peak gives a peak-to-average ratio of 3.5x; these are not observed facility measurements. This ratio is a primary driver of automation sizing decisions and utilization risk. A system sized for peak must carry excess capacity during average periods, depressing utilization and weakening economics. A system sized for average throughput cannot fulfill peak demand without supplemental labor. Compare flexible and fixed capacity against the facility’s actual demand profile and complete cash flows. No peak-to-average ratio alone establishes a preferred architecture or investment viability.
