An object-oriented approach to discrete-event simulation applied to underground railway systems

This paper describes the implementation of an object-oriented simulator tha t support the determination of timetables and the design of on-line conf vo l policies for underground railway systems. The simulator has been develope d ::: on the basis of a new approach to object-oriented modelling. Such an approach has been used to design a development tool that supports the gener ation of simulation codes and is able to automatically define the skeleton of a code.
