Problems solved by technology
[0005] At present, the interaction between ships and facilities is mainly reflected in the scheduling of optimized facilities. However, except for ship locks, other facility nodes have received less attention from scholars.
However, for key areas such as narrow and busy waters and intersections where traffic flows converge, the interaction between ships increases, and congestion and collisions are prone to occur, which is also an important node worthy of attention

The invention discloses an intersection water area space-time resource allocation method based on ship-shore cooperation, and the method comprises the following steps: S1, the space-time resources of an intersection water area are defined as space-time resource blocks, the behaviors of a ship in the intersection water area are divided into crossing, afflux and afflux, and the space-time resource blocks occupied by different behaviors of the ship are different; and S2, a hybrid integer optimization problem by taking the total passing time of the ships in the minimum finite time as an objective function and taking the exclusive occupation of a single ship on a space-time resource block as a constraint is established, thereby reducing conflicts of the ships in an intersection water area by formulating the arrival time and passing speed of the ships. According to the invention, reasonable distribution of space-time resources of the intersection water area is realized, and the passing efficiency of ships in the intersection water area is improved.
Description
technical field [0001] The invention relates to the field of water traffic organization, in particular to a method for allocating space-time resources in converging waters based on ship-shore coordination. Background technique [0002] In the water transportation system, various types of facilities, such as ship locks, intersections and ports, converge traffic flows in different directions, resulting in complex traffic scenes and frequent accidents. Improving the traffic safety and efficiency of facilities can effectively improve the overall performance of water transportation system. [0003] Improving traffic safety and efficiency at facilities aims to minimize the time it takes for ships to pass through various facilities. The passage of ships through these facilities can be regarded as an occupation of time and space resources. Therefore, the main problem to be solved is the allocation of space-time resources, usually expressed as different scheduling problems, such as...
