A line that stops costs more per minute than almost anything else in manufacturing. Applix works on changeover, on the quality loop that follows it, and on the maintenance that decides whether either happens on plan.
Large assemblies, long cycles, deep bills of material and configurations that are effectively one-off. The cost of a mistake is measured in weeks, so the work is to catch it before the weld.
Every operation has to be provable years after it happened, under an audit that assumes nothing. Applix treats the record as part of the process rather than as a thing written up afterwards.
Continuous process, narrow operating windows and a maintenance programme that cannot simply stop the line to look. The question is almost always whether a drift is real and what it is drifting towards.
Short runs, frequent changeovers, cleaning cycles that consume the time the plan assumed was production, and a traceability requirement that reaches the individual pallet.
