The purpose of the final work is forming a simulation model of the process of reloading of oil in the oil terminal that would let make a simulation model of accepting oil products by railway to the oil terminal. In order to fulfil the purpose of the final work there were some tasks risen: a conceptual model of reloading process of oil was made, a mathematical model of reloading process of oil was made, too, an aggregate diagram of the simulation model was made an the models of the classes of the program realization were shown as well. The object of the final work is the simulation model of the process of reloading oil created in the oil terminal. Having used an object–oriented simulation system library of simulation modelling JPranas and AgDraw program, the programming realization of simulation model in Java programming system was created. The results of the final work: experiments with the created simulation model of reloading process of oil in order to find out the optimum solution have been created. The created simulation model allows changing these parameters of the model: 1. The intensity of arriving of trains at the railway station. 2. The temperature outside. During modelling the returns got for reloading oil were bring counted and, on the other hand, expenses of oil terminal for reloading oil were being counted as well. The graphic expression of the returns, the expenses and the profits showing the optimum industrial capacity of oil terminal have been presented... [to full text]
