Formula Reference

S1 AMR batch time = route distance / AMR speed + docking / traffic allowance
S1 takt = max(grind cycle, cobot service) + AMR batch time / batch size + inspection batch allowance / batch size
S2 takt = max(superfinish process, load/unload handling) + transfer allowance + inspection allowance
S3 takt = (degrease cycle + load/unload + blow-off + cooling) / batch size
S4 takt = (conveyor distance / conveyor speed + index / tray exchange) / batch size + buffer allowance
Single robot S5-6 takt = presence + pick/orient + datum + OD + decision + single robot move allowance + laser + vision + unload + reject allowance
Two-robot S5-6 takt = max(Robot A loop, measurement station, Robot B loop, laser/vision station) + handoff/index allowance
Whole-line bottleneck takt = max(active stage takt values for the selected option boundary)
Daily output = ((shift hours x 3600 x OEE) - transfer losses) / bottleneck takt
Good output = gross output x (1 - reject/rework loss %)
