PORT DEVELOPMENT SIMULATION
The reasons of interest to the ports model's development are explained in this paperwork. The need to create a model of a new type of port development was identified as well as requirements to be met. The choice of the methodical basis based on cargo aspects of port operations is proved. Main factors examined for their individual and joint impact on the port as a single system. The algorithm of the simulation model, considering the influence of the identified constraints. The model includes the possibility of structural changes in the types of cargo flows as initial data, as well as the possibility of changing the percentage of the components of cargo flows, which may vary depending on the situation. Construction of the model is carried out by step-by-step complication of the task, which is to introduce additional restrictions that affect the development of the port. This implementation allows to track the development of the port in the event of new factors and changes in the impact of existing external and internal restrictions. The tests of the model in different variants of the development of traffic flows were done. The adequacy of the simulation model is determined. It is shown that the model proposed in the work is the mathematical apparatus, which covers the whole process of port development from the inception of the traffic to the stage of specialization of the port that allows you to simulate the process and calculate different variants of development depending on the strength and direction of influence of different forces and factors in the development of the created model allows to consider the development of a certain port based on specific conditions. The model not only explains the current state of the port and the reasons that led to it, but also gives a forecast of development in the future, which is the most valuable for practical application.
