An installation that is operating at or near full system capacity
might want to encourage better use of its limited resources through
billing. The major billing objectives of such an installation might
include:
- The users must pay only for the system resources they use.
- The rates for abundant resources must be lower than the rates
for scarce ones.
- The charges for each system resource must fluctuate with the demand
for that resource.
Assuming that it has cost-conscious users, the installation might
use degradation and/or efficiency billing, as described in other topics,
to satisfy these objectives.
