Find the bottleneck before peak does.

Drag real warehouse automation onto a live floor (cube AS/RS, AMR goods-to-person, shuttles, case-handling robots, pocket and cross-belt sorters, auto-baggers, palletizers) and watch orders flow from release to the trailer. The binding constraint lights up, queues pile where it hurts, and every late order gets a dollar figure.

Utilization & queues by node

Warehouse automation in use today

Every tile in the library is modeled on equipment running in DCs right now. Rates are typical published and field ranges; your vendor, SKU mix and labor will move them, so treat them as starting points and replace them with your own numbers.

How the model works

A discrete simulation on a one-second clock, run in your browser. Nothing is uploaded.

Orders

Orders arrive waveless (random arrivals at your hourly rate) or in waves. Each gets random lines and units around your averages and a due time of release + SLA.

Nodes

Each node has servers (ports, aisles, pickers, inducts, doors) and a rate or cycle time per line, unit or order. Staffing below the requirement idles servers. Buffers are finite, so a full node blocks the one feeding it.

Conveyor & WES

Conveyors have length and speed and accumulate at about one tote per meter. The WES sends work to the least-loaded downstream node, or splits it by fixed % (e.g., by client).

Money

Late = shipped after due, or still open at shift end and already past due. Cost = late orders × your $/late order + labor hours × wage. Advisor capex figures are illustrative ballparks; use your own quotes.
