Close control and scheduling of individual empty freight-car fleets has been sought for some time as answer to low car utilization and erratic customer service; certain properties of network formulation conveniently guarantee integral solutions to problem; extension of this model into type of multi-commodity network flow problem representing road locomotive fleets is being explored; problem cannot be solved with integer arithmetic, but need for integer solutions remains, which are being used in effort to find reliable and efficient solution technique.
