4. BALTPORTS-IT - IST-2001-33030 ____________________________________________________ Expected results Simulation system permits to estimate the following characteristics: –Order execution duration from time instant when the order has been done till tanker leaves the terminal; –Time of storage of oil products in terminal reservoirs; –Stay durations of wagons and tankers in terminal for different kinds of oil; –Number of wagons in terminal railway station for each kind of oil product.

5. BALTPORTS-IT - IST-2001-33030 ____________________________________________________ Approach Formalization of terminal operations has been done using aggregate approach. Aggregate approach is widely used for formal description, simulation and validation of complex systems. The general idea of the method is system is decomposed to separate piece- linear aggregates (PLA) and each PLA of the system is described using the method of controlling sequences. The advantage of this approach is its ability to mathematically strictly describe analysed system. Model formal specification has been implemented using ARENA simulation tool.
