Abstract
Railway nodes represent sensitive points of railway networks, the efficiency of
which influences the effectiveness of network processes. Those nodes belong to
the most complex service systems involving sophisticated technological
processes and are equipped with quite complicated and costly technical devices.
Design of those systems and the organization of their operation have to facilitate
the required capacity together with a high quality of service processes as well as
minimal costs of resources. That intention can be achieved using various
measures, e.g. track infrastructure modification, utilization of alternative kinds of
resources, improvement of scheduling and rostering, enhancement of
technological processes, adjustment of decision making strategies or entire
system reengineering (that approach can be applied to a design of a new node).
The application of exact mathematical optimisation methods is quite limited
because of the high complexity of the above-mentioned systems. Computer
simulation offers a quite flexible and credible technique eliminating the
disadvantages of precedent approaches, i.e. a simulation model of railway node
(substituting an existing or planned system) enables one to investigate all
mentioned ways of an increase of node capacity. Efficient methodologies are
introduced aimed at the solution of capacity problems related to railway nodes
using the simulation software tool Villon, which was originally determined for
simulations of railway marshalling yards; however its flexible hierarchical
software architecture enabled us to extend its scope to other kinds of
transportation nodes (including e.g. automobile traffic).
Keywords: transportation node, simulation model, planning, optimisation.
Keywords
