[0002] With the continuous growth of global energy demand, coal, as one of the main energy resources, plays a crucial role in the energy supply chain. Coal-fired transportation ships, as an important link between coal mines and power plants, their transportation management is of great significance for ensuring energy supply, improving transportation efficiency, and reducing transportation costs.

[0003] Traditional methods for the transportation management of coal-fired transportation ships mainly rely on manual experience and simple rules, lacking scientificity and accuracy, resulting in inefficient and unstable transportation plans. Moreover, under the traditional management mode, there is no overall planning for the navigation, berthing, and unloading of coal-fired transportation ships, and the coordination between navigation, berthing, and unloading is not close enough, leading to low information transmission efficiency between various processes and being unable to make a tight and efficient ship transportation plan. Additionally, due to the lack of effective scheduling and planning means for coal-fired transportation ships under the traditional management method, the transportation efficiency of coal-fired transportation ships is low, resulting in too long coal transportation time on each coal-fired transportation ship and high overall coal transportation costs.

[0028] In an embodiment of the present application, a method for the dispatching management of coal - transporting ships is provided. The method of constructing an objective function with the shortest coal transportation time of all coal - transporting ships includes: Min T = + + , Among them, Min T is the shortest coal transportation time of all coal-fired ships, Ti is the sailing duration of the i-th coal-fired ship, To is the berthing duration of the o-th coal-fired ship, Te is the unloading duration of the e-th coal-fired ship, and n is the number of coal-fired ships.

By adjusting the sailing, berthing, and unloading plans of the ships, the total transportation time is minimized, thereby improving transportation efficiency and reducing costs. This step helps to optimize the ship scheduling and transportation plan, making the entire coal transportation process more efficient and economical.

[0030] In the embodiments of the present application, a method for dispatching and managing coal transportation ships is provided. According to each group of ship sailing plans, each group of ship berthing plans, and each group of coal unloading plans of each coal transportation ship, the sailing constraints, berthing constraints, and unloading constraints of each coal transportation ship are determined, including: obtaining each group of ship sailing plans of each coal transportation ship, and based on the route information in each group of ship berthing plans, under the conditions of ensuring that each coal transportation ship enters the route for sailing at an allowed time point, ensuring a safe clearance distance between the coal transportation ships traveling on each waterway, and ensuring that each coal transportation ship can complete the sailing within a certain time on each optional route, determining the sailing constraints of each coal transportation ship; obtaining each group of ship berthing plans of each coal transportation ship, and based on the status information of each coal loading and unloading area in each group of ship berthing plans, under the conditions of ensuring that each coal transportation ship enters each coal loading and unloading area for berthing at an allowed time point, ensuring that the coal load of each coal transportation ship is less than the remaining capacity of the area, and ensuring that all loading and unloading equipment has completed unloading after each coal transportation ship arrives at each coal loading and unloading area, determining the berthing constraints of each coal transportation ship; obtaining each group of coal unloading plans of each coal transportation ship, and based on the unloading capacity of each coal loading and unloading area in each group of ship unloading plans, under the conditions of ensuring that each coal transportation ship enters each coal loading and unloading area for unloading at an allowed time point, and ensuring that the coal of each coal transportation ship enables all loading and unloading equipment to complete the unloading task within a certain time, determining the unloading constraints of each coal transportation ship.

[0031] Specifically, when ensuring that each coal transportation ship can enter the shipping lane for navigation at an allowed time point, it is necessary to ensure a safe clearance distance between each coal transportation ship sailing on each shipping lane. This requires considering factors such as the width and depth of the shipping lane and the speed of the ship to ensure the safety of ship navigation. When ensuring that each coal transportation ship can complete navigation within a certain time on each optional shipping lane, it is necessary to avoid the ship choosing a longer route, resulting in too long a navigation time; when ensuring that each coal transportation ship can enter each coal loading and unloading area for berthing at an allowed time point, it is necessary to ensure that the coal load of each coal transportation ship is less than the remaining capacity of the area, and to ensure that all loading and unloading equipment has completed unloading after each coal transportation ship arrives at each coal loading and unloading area; when ensuring that each coal transportation ship can enter each coal loading and unloading area for unloading at an allowed time point, it is necessary to ensure that the coal of each coal transportation ship enables all loading and unloading equipment to complete the unloading task within a certain time, and to avoid the unloading time of all loading and unloading equipment being too long and exceeding the normal working hours of the loading and unloading equipment. By considering factors such as the safe clearance distance during ship navigation, berthing and unloading and the remaining capacity of the loading and unloading area, the system can ensure the operational safety of coal transportation ships in each link; it can comprehensively consider and constrain the constraint conditions during ship navigation, berthing and unloading according to the actual situation, combined with ship characteristics, shipping lane conditions, the status of loading and unloading equipment, etc.; on the premise of meeting the constraint conditions, the system can optimize the navigation, berthing and unloading plans of the ship, improve the transportation efficiency of the port and reduce the transportation cost. This step can help achieve safe and efficient operation of coal transportation ships during navigation, berthing and unloading, improve the transportation efficiency of the port, reduce transportation risks, and contribute to enhancing the intelligent management ability of ship scheduling.
