SCHEDULING RULES FOR A CLASS OF FIXED ROUTE FREIGHT SCHEDULING PROBLEMS

While scheduling problems have received prominent attention in the airline industry, comparatively little analytical work has been done concerning such problems in the railroad industry. In this report, problems involving both a scheduling and routing aspect are considered based on the movement of freight on railroads. Viewing the freight as jobs to be processed and the trains as a system of parallel processors allows one to develop optimal scheduling rules for transporting the freight on fixed route railway networks for various optimality criteria. Rules are presented for cases when the route consists of a single track serviced by one or more trains operating on a fixed schedule. Cases in which the jobs and/or trains may be subject to certain availability restrictions are also considered.
