How to calculate OEE, and why most OEE numbers are wrong
The formula is simple. What is usually wrong is the denominator and the hand-written downtime log.

Nothing is carried by hand between the shop-floor tablet and the accounting entry. A confirmation issues components, receives finished goods and books work-in-progress cost in one step.

Ключевые возможности
Bill of material
Revision-controlled structures with fixed and proportional consumption, scrap rates and phantoms.
Routing and work centres
Operation sequence, setup and run times, subcontracted steps, generated capacity.
Work orders
Releasing snapshots components and operations, so later engineering changes cannot corrupt an order in progress.
Shop-floor kiosk
Touch MES with QR resolution of machine and operator, downtime reasons, good and scrap reporting.
Backflush and WIP
One confirmation issues components, receives output and books work-in-progress cost.
OEE dashboard
Availability, performance and quality per work centre, live when a machine agent is installed.
MRP
Demand, stock and structures combine into purchase and production action messages.
A released work order is frozen
What should happen to an order in progress when the bill of material changes? In most systems the order follows the new structure and what was physically built stops matching what the system recorded.
In Tokuva, releasing a work order snapshots its component list and routing operations. Later revisions do not disturb it. Quantity, structure and routing can only be changed while the order is still planned.
The kiosk removes the paper
An operator scans their badge and the machine label, picks the order and starts setup or run time. Reporting downtime requires selecting a reason — an unexplained stop cannot be saved, because that is exactly where the availability term of OEE comes from.
A confirmation does three things at once: it backflushes components, receives good quantity into stock while recording scrap separately, and loads labour and overhead onto work in progress as a posting proposal.
OEE is calculated, not estimated
Availability comes from the calendar and downtime records, performance from standard versus actual time, quality from good versus scrap counts. All three derive from data already entered; there is no separate OEE form to fill in.
