摘要：AbstractIn the railway networks management context, the determination of train schedules is a topic which affects both the level of satisfaction amongst the users and the network performance and profitability. This double influence makes it a widely studied topic in the literature, where nowadays the main lines of research tend to improve the solving methods of the corresponding integer programming problems. However, literature about methods that take both user and service provider point of view jointly into account is sparse. In this work, we tackle the problem of scheduling in middle and long distances networks by means of a non-linear integer programming model which fits the schedules to a dynamic behavior of demand and represents a trade-off between some measures of quality of the service offered and aspects related to the network profitability. The confrontation of different objective selection policies is analyzed in depth in the core part of this study, with the intention of both improving the insight into the proposed model and adding the flexibility of choosing different objectives by knowing in advance their influence on the resulting schedule plan.
