Decisions handed to agents0 of 0

This service has at most one gate, so there is nothing to hand over without removing the last human decision.

Where an item spends its time

41% waiting on a person

59% in the agent lane

An item now takes 990 minutes of worked time end to end against 990 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 Application Retirement

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

6 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.

4 counted categories land on this procedure. more

What this run cannot claim

These breaks are shown together on one unit so the shape of a bad day fits on one screen. more

The separation register records a duty conflict against a sub-function and a named post, not against one procedure. more
