Development of the mathematical model for optimization of management of seaport transfer processes

A mathematical model for managing the transfer process of the seaport is offered. The graph model of the system of transfer process management, in which all the likely routes of transportation of goods inside the port is designed. The graph-model includes a set of vertices that are loading and unloading points (piers, warehouses, railway station, etc.) and a set of arcs which is the direction (route) goods and vehicles movement. Functioning of the port cargo handling processes obeys Markov’s random processes. Therefore, the graph model of transfer processes is the state transition graph of the control system. Control system status is determined by freight stay in one of the vertices. Every transition from one vertex to another, indicating the movement of goods from one point to another, represents a change in the system. The problem to optimize the transfer process management is stated and the objective function for determining the routes of goods and vehicles movement in which the freight costs and processing of time vehicles will be minimal is defined.
