Technical Field

[0002] With increasing demand for resources, the demand for dry bulk cargo is also growing rapidly. Today, major dry bulk cargo ports play a vital role in global trade. China's dry bulk shipping market is also developing rapidly, injecting new vitality into the development of China's port industry. Currently, the transportation of dry bulk cargo is mainly via sea. To increase the utilization rate of port machinery resources, reduce the time ships spend in port, and improve port efficiency, improving the efficiency of dry bulk port loading and unloading operations and reducing ship time in port has become a common problem faced by major dry bulk cargo ports worldwide in recent years. There are two main methods to improve the efficiency of dry bulk port loading and unloading operations: first, increasing port resources, including berths and loading and unloading equipment; second, scientifically coordinating the allocation of resources for port loading and unloading operations.

[0039] Figure 1 This is a flowchart of the method for scheduling loading and unloading equipment in a timber yard according to the present invention. Detailed Implementation

[0040] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0041] For timber, the loading process is as follows: a log clamping machine places timber from the timber yard onto a transfer vehicle, which then transports the timber from the yard to the ship's berth. The log clamping machine then moves the timber from the transfer vehicle onto a gantry crane, which finally transports the timber onto the ship. The unloading process is the reverse of the loading process.

[0042] To maximize the efficiency of timber loading and unloading operations, this invention provides a method for scheduling loading and unloading equipment in timber yards, such as... Figure 1 As shown, it includes:

[0043] S1. Obtain Task Requirements. Task requirements include berth requirements, target yard requirements, and operation time requirements. Specifically, task requirements are obtained from the port's full-process production scheduling model. Operation time requirements include start and end times. Start time is the time when loading and unloading operations can begin after the vessel berths. End time is the required departure time.

[0044] S2, determine the number of gantry cranes based on the required operation time; determine the gantry crane to be used for the current task based on the number of gantry cranes.

[0045] Specifically, S2 includes:

[0046] S21, Obtain the maximum number of gantry cranes that can be operated on the vessel. The maximum number of gantry cranes that can be operated on the vessel is the maximum number that can be operated simultaneously, and is determined based on the size of the vessel and the actual situation.

[0047] S22. Determine the initial number of gantry cranes based on the required operating time, the total loading and unloading workload, and the unit time workload of the gantry cranes.

[0048] Specifically, the total loading and unloading volume of a single gantry crane within the required operating time is determined based on the crane's workload per unit time.

[0049] Divide the total loading and unloading volume by the total loading and unloading volume of a single gantry crane and round up to obtain the initial number of gantry cranes.

[0050] S23, when the initial number of gantry cranes is greater than the maximum number of gantry cranes in operation, the maximum number of gantry cranes in operation shall be used as the number of gantry cranes; when the initial number of gantry cranes is less than or equal to the maximum number of gantry cranes in operation, the initial number of gantry cranes shall be used as the number of gantry cranes.

[0051] S24. Determine the gantry cranes to be used in the current task based on the number of gantry cranes. Specifically, acquire the gantry cranes that are idle after the start of the work period, and select the gantry cranes whose ownership belongs to Party A as the working gantry cranes for the current task. If the number of gantry cranes whose ownership belongs to Party A is less than the total number of gantry cranes, select a predetermined number of gantry cranes from those whose ownership belongs to a third party as the working gantry cranes for the current task. The predetermined number is the total number of gantry cranes minus the number of gantry cranes whose ownership belongs to Party A.

[0052] S3. Determine the loading and unloading route based on the location of the loading and unloading berth and the target yard, and determine the number of transfer vehicles corresponding to each gantry crane based on the loading and unloading route.

[0053] Preferably, S3 includes:

[0054] S31. The loading and unloading route is determined based on the location of the loading and unloading berths and the location of the target storage yard. The loading and unloading route is obtained by optimizing the overall port transportation route, taking into account routes that need to be avoided, the location of the loading and unloading berths, and the location of the target storage yard.

[0055] S32, determine the loading and unloading volume of the transfer vehicle per unit time based on the loading and unloading route.

[0056] S33: Divide the unit time workload of the gantry crane by the unit time loading and unloading volume of the transfer vehicle and round up to get the corresponding number of transfer vehicles.

[0057] S4, determine the work transfer vehicle for the current task based on the number of each transfer vehicle.

[0058] S5. Determine the number of log clamping machines based on the number of gantry cranes and the number of each transfer vehicle; determine the log clamping machine to be used for the current task based on the number of log clamping machines. Specifically, the number of log clamping machines is the sum of the number of gantry cranes and the number of each transfer vehicle, so that the log clamping machines can simultaneously meet the operational tasks of both the gantry cranes and each transfer vehicle.

[0059] The present invention also provides a loading and unloading equipment scheduling system for timber yards, comprising:

[0063] The transfer vehicle determination module is used to determine the work transfer vehicle for the current task based on the number of each transfer vehicle.

[0064] The log clamping module determines the number of log clamps based on the number of gantry cranes and the number of each transfer vehicle; and then determines the log clamping machine to be used for the current task based on the number of log clamps.

[0065] Preferably, the number of door operators module is as follows:

[0066] Obtain the maximum number of gantry cranes that can operate on the vessel.

[0067] The initial number of gantry cranes is determined based on the required operating time, the total loading and unloading volume, and the unit time operating volume of the gantry crane.

[0068] When the initial number of gantry cranes is greater than the maximum number of gantry cranes in operation, the maximum number of gantry cranes in operation will be used as the total number of gantry cranes; when the initial number of gantry cranes is less than or equal to the maximum number of gantry cranes in operation, the initial number of gantry cranes in operation will be used as the total number of gantry cranes.

[0069] Based on the number of gantry cranes, determine the gantry crane to be used for the current task.

[0070] Furthermore, the module for the number of transfer vehicles is as follows:

[0071] The loading and unloading route is determined based on the location of the loading and unloading berth and the location of the target storage yard.

[0072] The loading and unloading volume per unit time of the transfer vehicle is determined based on the loading and unloading route.

[0073] Divide the unit time workload of the gantry crane by the unit time loading and unloading volume of the transfer vehicle and round up to get the corresponding number of transfer vehicles.
