Where an item spends its time

47% waiting on a person

53% in the agent lane

An item now takes 1,180 minutes of worked time end to end against 1,180 in the recorded estate, a change of +0%. This is worked time, not calendar time: nothing here models a queue or a weekend.

What this model is, on Payroll Cycle

The simulation is arithmetic on the estate, not a queueing model. more

How it runs

Run it again, going wrong

The same unit and the same stations, broken the way the estate already records breaking. more

9 stations, walked twice

Once clean, once with the categories the estate counts

This is the same unit on the same stations, breaking. more

No break below was chosen. more

One play head, two tracks, the same scale. The clean run stops when it runs out of stations; the other one keeps going.
