Specifically, because the navigational speed and the navigational attitude of the ship both have the maximum value and the minimum value, a plurality of preset navigational information corresponding to the navigational task can be generated by taking the navigational speed and the navigational attitude both have the maximum value and the minimum value as constraint conditions; then, the navigation information and the preset navigation information are respectively input into a comprehensive index calculation module in a comprehensive decision model to obtain a comprehensive index corresponding to the navigation information and a comprehensive index corresponding to the preset navigation information, when the comprehensive indexes corresponding to the preset navigation information are all smaller than the comprehensive index corresponding to the navigation information, the comprehensive decision model is determined to be effective, namely when the comprehensive indexes corresponding to the navigation tasks are all smaller than the comprehensive index corresponding to the navigation information calculated in the step 1 and the step 2, the comprehensive decision model is determined to play an application function, namely when the comprehensive index formed when the ship navigates according to the control instruction generated by the comprehensive decision model is superior to the comprehensive index corresponding to the ship navigates according to any other control instruction, the test result is determined to be effective, and particularly, the ship navigates according to the control instruction generated by the comprehensive decision model, namely, the ship navigates according to the navigation instruction pair determined by the comprehensive decision model The ship navigates according to the navigation information, and the ship navigates according to other control instructions, namely, the ship navigates according to the preset navigation information corresponding to the navigation task.

step S202: and inputting the obtained initial test parameters into the comprehensive decision-making model.
In one embodiment, the initial data parameters include virtual environment parameters and virtual ship parameters, and may be obtained through numerical simulation, that is, through a pre-established environment test model. Specifically, the initial test parameters may include: sea environment parameters such as wind, wave and current, electronic chart information, ship parameters, ship-mounted equipment parameter import of the ship, ship information, ship navigation parameters, navigation tasks and the like. The parameters can be selected from various options, such as marine environment parameters, low sea condition scenes favorable for ship navigation, typhoon cold tides and other extreme sea condition fields; the electronic chart can be selected from open water areas, port water areas and the like; the ship parameters comprise ship type, size, draught and the like, and can be selected according to different ship types; the ship-borne equipment parameters of the ship comprise turbine parameters, steering engine parameters and the like, and the ship-borne equipment cannot change after being installed on the ship, so that the ship-borne equipment parameters can be automatically imported after the ship-borne equipment parameters are imported; the ship information mainly comprises: the ship type, the size and the draught can be randomly selected within a reasonable range; the navigation parameters of other ships comprise: the navigation speed, the course, the drift angle, the steering angle and the like can be randomly selected in a reasonable range according to the information of other ships; the navigation tasks include: the starting point coordinate, the ending point coordinate, the navigation duration and the like of the air route can also be randomly selected within a reasonable range.

Step S206: the turbine simulation model and the steering engine simulation model respectively output a rotating speed command and a steering angle command to the numerical pool model, and the turbine state parameters and the steering engine state parameters are fed back to the comprehensive decision model.
Specifically, the turbine simulation model can output the rotating speed of the propeller to the numerical pool model, and the steering engine simulation model can output parameters such as a rudder angle to the numerical pool model.
Step S208: and the numerical pool model determines the navigation information of the ship according to the received rotating speed command, rudder angle command and attitude command, and feeds the navigation information back to the comprehensive decision model for storage and recording. Specifically, the navigation information of the ship includes: navigational speed, trajectory, motion response, force, etc.

Specifically, the updated calculation times can be set according to the calculation capability of the computer, and the navigation information of the ship obtained by each calculation, namely the speed, the navigation attitude and the course of the ship, is recorded.
Step S212: and testing the comprehensive decision model according to the navigation information.
In one embodiment, M sets of voyage missions may be randomly generated within a reasonable range, keeping the initial test parameters in step S202 the same. Because the navigational speed and the attitude of the ship have the maximum value and the minimum value, the reasonable range can be determined according to the navigational speed and the maximum value and the minimum value of the attitude of the ship, and the navigational speed and the maximum value and the minimum value of the attitude of the ship can be searched from a loading manual of the ship. In addition, the generated voyage task should also satisfy that the planned voyage time of the whole voyage is the same as the target voyage time.
