A modular tool for prediction of design choices impact on railway service dependability

Service dependability has been recognized in the transportation literature as an effective measure of transit systems service quality. Being a stochastic measure of the delay collected by a train in a generic travel, it may be profitably utilised as an indicator to choose, among different options, the design solution able to increase the level of satisfaction of the final user as well. In this paper the authors present a procedure for estimating the impact of design choices, dealing with subsystems architecture, basic components reliability performances or maintenance policies, on the service quality provided by a railway or metro system. The procedure is based on the use of an innovative modular simulator, developed by the authors. Through a Monte Carlo approach and a suitable post-processing of the results of the simulated samples, the tool provides the user with a set of indicators for estimating the service quality and the effectiveness of different traffic and fleet management policies, as well as maintenance strategies, in both rated and degraded operating conditions.
