Intelligent index for railway track quality evaluation based on Bayesian approaches
Structure and Infrastructure Engineering, 2020Concerning the optimal balance between the limited budget and maintaining the desired performance and safety level in railway infrastructure, it is necessary to prioritize railway track qualities. Although different directives recommend different indices,

This chapter addresses the classical task to decide which train runs on which track in a railway network. In this context a track allocation defines the precise routing of trains through a railway network, which usually has only a limited capacity. Moreover, the departure and arrival times at the visited stations of each train must simultaneously meet ...

THE FUNCTION OF THE REFERENCE LIBRARIAN is to conduct requests for knowledge to known or to possible sources. He can sometimes do this by turning with arm‐length familiarity to a bay full of familiar friends —B.N.B., Besterman, Walford, Britannica, Willings ‐ and an increasing number and variety of bibliographical aids to specialized fields in current ...
