cze	Analysis and optimisation of railway nodes using simulation techniques	Railway nodes represent sensitive points of railway networks, the efficiency of which influences the effectiveness of networks 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 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 high complexity of the above-mentioned systems. Computer simulation offers quite flexible and credible technique eliminating disadvantages of precedent approaches, i.e. simulation model of railway node (substituting existing or planned system) enables to investigate all mentioned ways of an increase of a node capacity. There are introduced efficient methodologies aimed to the solutions of capacity problems related to railway nodes using simulation software tool Villon, which was originally determined for simulations of railway marshalling yards; however its flexible hierarchical software architecture enabled to extend its scope to other kinds of transportation nodes (including e.g. automobile traffic).
