Playback in 3D

Why it matters

Numbers convince engineers. Pictures convince everyone else. Playback shows the simulated week on the 3D model: trucks at the doors, forklifts in the aisles, floors filling up. It is the fastest way to show a room full of people why the six o'clock truck was late.

In plain words

Playback is a recording, not a new simulation. The run wrote down every event: this truck docked at 07:16, that forklift picked up a pallet at 07:18. Playback reads the list and draws where everything was at the time on the clock. That is why you can scrub backwards and forwards freely.

5 min/s is a good speed for a demonstration: a whole shift passes in under two minutes.

What you see

• Trucks at the doors. A truck past its departure time turns red.
• Forklifts on the aisles: unloading, putting away, loading.
• Floors fill and empty, with their count, for example Dispatch floor 99 / 120.

The panel

Section	Shows
Now	At the doors, waiting for a door, forklifts moving, pickers & packers, each floor's fill, pools on shift.
Doors	Which truck is at which door.
Just happened	The last few events before the moment on the clock.
Show & legend	What is drawn, and in which colours.

Close playback returns to the plain 3D view.

What playback cannot show

• Only replication 1 is played.
• A picker on a case or each tour has no single bay to stand at, so it stands in its zone, and the panel says so.

Try it

Play the demo's Baseline at 5 min/s. Scrub to about 16:10 on a weekday. How many trucks are at the dispatch doors, how many are red, and how full is the dispatch floor? That picture is the dispatch problem from the results, made visible.
