Abstract :
A successive linear program m i n g
methodology is presented to treat more effectivefy
those applications where a local structure change is
performed to a system already in operation, and
where the modification of the settings of already
existent relays is not desirable. The dimension of
the optimization problems to be solved is substantially
reduced, and a sequence of small linear programming
problems is stated and solved in terms of
the time dial settings, until a feasible solution is
reached. With the proposed technique, the number
of relays of the original system to be reset is reduced
substantially. It is found that there is a tradeoff
between the number of relays to be reset and the
optimality of the settings of the relays.
