The article gives a complete mathematical description of the system «Ship» on the example of a container ship with its own cargo gear. On the one hand, this type of vessel is quite common in the world fleet, on the other hand, to justify its shipbuilding elements can be used already known methodological approaches. The system «Vessel» includes 8 subsystems. The key criteria for the development of this system – the cost of the entire system. The article presents a detailed description of each subsystem separately. The following parameters are calculated to optimize in each subsystem, in addition to its own characteristics, that determine the properties of the vessel: the mass of the subsystem P; the volume required to accommodate the subsystem W; power consumption of the subsystem E; application of the center of gravity of the subsystem Z, the cost of the subsystem S, the objective function (optimization function) of the subsystem F. The presented mathematical model includes algorithms for solving global and local optimization problems and matching the obtained optimal solutions to each other to solve the problems of consistency.
