e-Kanban cards that become claimable work orders
A digital empty or low card is a pull signal, not a finished logistics job. The loop closes when that flip opens a claimable work order the right driver group can accept.
What e-Kanban is and what a board color still misses
e-Kanban is electronic kanban: a scan, smart bin, button, or system threshold replaces a paper card or visual empty. The method stays pull, and the signal carrier becomes software. That upgrade cuts lost cards and delayed handoffs that classic loops suffer when someone must walk the board. It is still not internal logistics management if the only result is a red tile on a wall or a status in a dashboard nobody owns.
Industry e-Kanban and lean replenishment stacks usually insist on the next step. The empty or low event becomes a warehouse pick, transfer, or logistics task with material, destination, priority, and status, often into a WMS or shared logistics queue. Circuits that rely only on visual management and never launch an electronic order stay open-loop by design. twinzo AOS (commonly known as a forklift guidance system (FGS)) is the hall marketplace that turns the flip into a claimable work order for a configured driver group. The card state is the request trigger. AOS is the offer, the accept lock, and the completion record. How triggers are wired is under request triggers in the workflow editor. How MES versus human buttons share ownership is under when MES should open the job vs when the line button should.
How the card should land in the right group
Map each card loop to the stage and vehicle that actually moves the material. A supermarket e-Kanban flip often opens prep work first, then a tugger milk-run delivery once trolleys are ready. A station e-Kanban for a pallet-size need usually opens a direct forklift job. Broadcast the offer to the group that owns that stage. Keep offer scope as group broadcast. Do not assume AOS selects the nearest truck. The templates are described in milk-run orders vs direct forklift orders. The general path from floor ask to claimable job is under how a floor request becomes a work order.
When movers are tracked, acceptance place and path still land in the spatially oriented dataset under the live hall. That record is what later correlation and causality analytics use to test which unclaimed or slow card loops keep preceding the same wait. Visual bins that never flip digital still fail the way paper failed: silent empties with no owner. If the card is digital but AOS is missing, the failure mode is a red tile nobody claims. Empties and returns that need the same marketplace treatment are under empties as a first-class call-off. Why place still matters beside pull is under pull and e-Kanban still fail without place.
e-Kanban pull versus milk runs sized to theory
A milk run planned on theoretical consumption pushes trolley material on a clock through supermarket prep and tugger delivery. e-Kanban pulls when the bin or card actually empties. Plants often need both. Keep the milk-run multi-stage path for stable high-volume loops. Wire e-Kanban into AOS so real empties open the correct stage: supermarket prep, tugger delivery, or direct forklift bring. That mix is a practical lean manufacturing and smart manufacturing move for inventory management at the station, not a choice between a tour and a card.
Scrap spikes and defective material are the rare case where demand jumps off the plan. For those, a labeled exception trigger still belongs in the marketplace instead of a radio shout. When a card flips on one loop while another milk-run lap is quiet, do not dump a pallet job into the tugger group. Use forklift capacity freed by the quieter period, and keep vehicle classes in separate groups. That capacity mix is under milk runs on theoretical consumption vs dynamic pull across lines. Offer scope stays group broadcast, covered under group broadcast vs nearest-truck myths.
What a closed e-Kanban loop must prove
A closed loop has four checkable facts on one record. The flip creates a work order ID. The correct driver group sees it. Someone accepts, which locks the job so a second driver cannot take it. Complete clears the need on the same trail. A board that stays red until accept is fine. A board that never opens a job is not. Response time and aging flips then become measurable material call-off KPIs instead of guesses about who watched the wall.
That trail is also the start of the place-and-time history continuous improvement needs. Live shift operations use the claim to move material. The stored acceptances and paths fill the spatially oriented dataset. Correlation and causality analytics later ask which card families keep aging before the station starves. Those three jobs sit on the same closed loop, not on three separate apps.
How teams decide e-Kanban is connected
1. Trace one card flip to a work order ID - If you cannot, the marketplace is not wired.
2. Confirm the right driver group sees it - Wrong group means wrong claims or silence.
3. Require accept and complete on the same record - A red tile alone is not a closed loop.
4. Review unclaimed card flips weekly - Aging flips are group, priority, or template problems.
