Embodiment

[0064] Such as figure 1 As shown, the present embodiment provides a method for ship path planning, and the specific steps are as follows:

[0065] S1: Establish a mathematical model for the maritime logistics situation, determine the number of ports in the ship's navigation area and the ship's load capacity based on the ship's voyage plan, the maritime climate environment, and changes in the topography of the route, and determine the route dispatched in the route optimization problem under the voyage plan Mathematical expressions for the number of ships;

[0066] In the present embodiment, the mathematical model of the maritime logistics situation in step S1 assumes that the number of ports is m, and if the total amount of goods required by the i-th port (0i , the load capacity of each ship is p, then for the problem of ship path planning, the number k of ships to be dispatched is expressed as:

[0067] k=[∑g i / bp]+1

[0068] Among them, b(0i >p.

[0069] S2: Construct th...

Abstract

The invention discloses a ship navigation path planning method, system, medium and equipment, and the method comprises the steps: building an offshore logistics condition model, determining the numberof ports and ship carrying capacity of a ship navigation area according to the ship navigation plan, an offshore climate environment and the change condition of topography and geomorphology in a route, and determining the number of ships needing to be dispatched; constructing an objective function and a constraint condition of an optimal path for the paths of the ships needing to be dispatched among different ports; establishing a ship navigation path optimization model; combining historical data of a ship navigation plan; and calculating an optimal navigation path by adopting an ant colony algorithm: initializing defined parameters, converting port coordinate information into a distance matrix between ports, searching for paths between different ports by utilizing ants, recording iteration times and updating pheromone concentration according to path lengths, and outputting the optimal path after the maximum iteration times are reached. According to the invention, the economic cost consumed by offshore logistics and invalid driving of the ship are reduced, and the economic benefit is improved.

Description

technical field [0001] The invention relates to the field of intelligent research on marine logistics and ship route optimization, in particular to a ship navigation route planning method, system, medium and equipment. Background technique [0002] With the development of society and technology, maritime trade among countries has become more frequent, which has led to the vigorous development of the shipping industry. The economy and safety of maritime logistics have become an important factor that countries currently pay attention to. [0003] The frequency of ship scheduling and voyages in various ports in various countries is becoming more and more frequent. How to reduce the cost of ship navigation routes has become a key competition point for shipping companies. Reasonable planning of the best dispatch strategy and optimal transportation route in ship shipping tasks can reduce maritime logistics. The economic cost consumed in the process and the invalid driving of the ...
