Generalized nets as a tool for modelling of railway networks

Abstract

The oldest public transport, which is used now days, is the railway. There exist different kinds of transportation models. The importance and role of each type of models is discussed in relation of its function. Some of the models are concentrated on scheduling. Other models are focused on simulation to analyze the level of utilization of different types of transportation. There are models which goal is optimal transportation network design. In this work we propose a model of the railway transport with Generalized Nets. It is shown that Generalized nets can be used as a tool for modeling of railway networks. An example of a generalized net of a part of the railway network in Southern Bulgaria, is given.
