Computer Assisted Revision Of Infrastructure Maintenance Policy
Author(s)

Abstract
Since 1998 Delft University of Technology develops and uses a Decision-Support System (DSS) for analysing the long-term impacts of railway design and maintenance decisions. The DSS combines data of construction, maintenance and operating, and financing processes in order to make estimates of total life cycle costs. Infrastructure performance (availability and reliability) is included in these estimates. DSS design and application, in a revision of the renewal policy for tracks and switches on the Dutch network, are presented. The DSS proved to be a valuable tool for testing the robustness of design and maintenance decisions and focusing the discussion on the important cost-driving factors.
