=

F=L×HwHrF = \frac{L \times H_w}{H_r}
=

What this part means

The expressions on both sides represent the same quantity under the stated assumptions.

Its job in the formula

The equals sign connects the complete expression on the left with the complete expression on the right. Both sides must have compatible units.

The passage around this formula

A robot’s usable hours depend on a different variable: duty cycle, the fraction of the 8,760-hour year a unit spends actually working rather than charging, undergoing maintenance, or switching tasks — run here across the same 90/70/50 percent grid this series applies throughout, giving 7,884, 6,132, and 4,380 operating hours per unit per year respectively. Solving the labor-hours ledger, F=L×HwHrF = \frac{L \times H_w}{H_r}. for fleet size F across all nine combinations of the labor-force total L , the hours-worked bracket HwH_w , and the duty-cycle-adjusted operating hours HrH_r , produces a range from about 0.76 billion units (90 percent duty cycle, 1,600 hours worked) to about 1.88 billion units (50 percent…
