Newer laundry machines have their
price controlled electrically, rather
than mechanically. This makes it
easy for the manager to switch the
prices. Usually, the price is simply
increased as the market will bear a
higher cost.
Imagine adding sensors to each
machine which can tell
if it is
currently running, or finished but not
yet unloaded. This information
would be wired to a central
computer, which would set a price to
start another machine. The more
machines in use (a not-yet-unloaded
machine counting as partially in use),
the higher the price. This would not
only curb congestion at peak demand
times, but would give a price break
to those willing to adjust their
schedules to come at low-demand
times.
