Abstract:

A model for the distribution of empty freight cars is presented. The perspective on empty-car distribution developed in this paper views the problem as a lack of coordination between decisions made centrally for the railroad as a whole and decisions made locally at individual terminals. Consequently, the model incorporates interacting submodels--the network model and the terminal model--that represent activities performed by these two levels in the railroad system. The objective of the network model is to maximize profits over the entire network, subject to the constraints imposed by empty-car supply and demand. The terminal model is an inventory-control model that incorporates stochastic demands and lead times for delivery of empty cars. Coordination between the two levels is achieved through internal transfer prices that reflect the opportunity costs of cars. The model can be used as a policy evaluation tool by railroad central management and an operational tool for the daily distribution of empty cars by terminal personnel. Tests of the model by using data from a cooperating railroad indicate that it leads to distribution decisions that reduce empty-car miles, empty trips, and empty-car days without reducing the percentage of demand satisfied.
