Abstract

A power distribution expert system is provided to determine an optimal power distribution configuration, and also to determine an optimal transition path to reach said optimal configuration. An exemplary first set of rules is provided to determine an optimal power distribution configuration. An exemplary second set of rules is provided to determine an optimum transition path to achieve the optimal power distribution configuration.
