The Maraca: a tool for minimizing resource conflicts in a non-periodic railway timetable

Abstract

While mathematical optimization and operations research receive growing attention in the railway sector, computerized timetabling tools that actually make significant use of optimization remain relatively rare. SICS has developed a prototype tool for non-periodic timetabling that minimizes resource conflicts, enabling the user to focus on the strategic decisions. The prototype is called the Maraca and has been used and evaluated during the railway timetabling construction phase at the Swedish Transport Administration between April and September 2010.Errata information: The version uploaded here differs in one respect from the published version on the RailRome 2011 proceedings CD-ROM: a duplicate row in Table 1 has been removed.Marackase
