An apparatus and method for routing calls to communication processing
centers based on an optimal destination plan. Calls are allocated on the
basis of area codes, regions, or other predetermined categories to
particular communication processing centers. Each communication processing
center's free capacity is calculated for all time intervals and this
result is used to ascertain the smallest free capacity of any time
interval for each communication processing center. The calls are then
reallocated through linear programming methods such that the amount of
smallest free capacity is maximized in order to determine the optimal call
allocation scheme.
