AN APPLICATION OF AHP METHOD FOR EXAMIN ING THE TRANSPORT PLAN OF PASSENGER TRAINS IN BULGARIAN RAILWAY NETWORK

摘要

In this study, a methodology was developed for transport plan selection ofintercity trains in railway network using the method of Analytic Hierarchy Process(AHP). For studying the transport plan, the following indicators have been chosen: thetransport satisfaction, average number of train stops, average distance travelled, averagespeed, reliability, availability of service with direct transport and transport capacity. Themethodology includes determination of variant schemes of transportation; determinationof the number of trains by criterion of minimum direct operating costs for transportationof each variant scheme using linear optimization model; application of AHP method todefine the weights of criteria and ranking the variants schemes; and selection of anoptimal transport plan according to the criterion of a minimum ratio of normalized directoperating costs to the AHP score. The methodology was experimented in Bulgarianrailway network.
