GENERAL MODEL OF A TRANSPORTATION SYSTEM
Keywords:
Transportation systems, modeling, optimization, simulation, system controlAbstract
Transportation systems are large distributed system. They may deal with various transportation modes (like road or railway transport, combined transports and transport in factories and production plants). Control and optimization problems from control of individual vehicles and transportation flows to optimization of transportation services and traffic in transportation networks are to be solved in all mentioned transportation systems. Model of the transportation system needs vast and expensive input data which should be possibly well exploited. A universal model of the transportation system can use the input data for a variety of applications without any regard to transportation mode, to differences in the detailed model description and to type of the optimization problem. A suitable tool for creating such a model is object oriented programming using virtual methods, polymorphism and inheritance of objects. The paper presents some experience in building such universal models and corresponding optimization methods of mathematical programming as well as methods of automatic control and simulation of transportation and logistic systems.
