The method recommends warehouse areas, warehouse locations and working points for operations through the working information of the working tasks corresponding to the working vehicles, and adds the working vehicles to the working point queues corresponding to the corresponding working points. Thus, for multiple warehouse areas where the working points do not interfere with each other, an independent queue is set for each working point in the warehouse area, and the working vehicles in the working point queues corresponding to the corresponding working points are scheduled based on the independent queues of each working point; for multiple warehouse areas where the working points interfere with each other, a shared queue is set for the entry working points of the multiple warehouse areas and a shared queue is set for the exit working points. The working vehicles in the working point queues corresponding to the entry working points are scheduled based on the shared queues corresponding to the entry working points, and the working vehicles in the working point queues corresponding to the exit working points are scheduled based on the shared queues corresponding to the exit working points, thereby realizing intelligent scheduling and control of multi-span crossing operations.

Description

Technical Field

[0001] The present invention relates to the technical field of operation scheduling, and in particular to a scheduling method and system for multi-span crossing operations in a steel coil warehouse. Background Art

[0002] Traditional coil warehouses, as key nodes in the steel logistics system, undertake core tasks such as the storage, allocation, and inbound and outbound processing of steel coils. Due to the heavy weight, large volume, diverse variety, and frequent inbound and outbound movements of steel coils, the complexity of storage and dispatch management is far greater than that of general materials. In large indoor coil warehouses, in particular, the coil storage area is typically divided into multiple "storage areas," each with several workstations. Work vehicles must perform multi-span operations across these areas.

[0003] As steel logistics transitions toward automation and intelligence, higher requirements are placed on the scheduling systems of steel coil warehouses. Therefore, coordinating the concurrent operation of multiple work points while ensuring safety and enabling efficient multi-span vehicle movement has become a core challenge in optimizing steel coil warehouse scheduling. Summary of the Invention

[0004] The present invention provides a scheduling method and system for multi-span passing operations in a steel coil warehouse, which are used to achieve efficient execution of multi-span passing operations by operating vehicles.

[0005] The present invention provides a scheduling method for multi-span crossing operations in a steel coil warehouse, comprising:

[0006] Obtaining the operating vehicles in the queue and determining the operating information corresponding to the operating vehicles; wherein, after any operating vehicle enters the park through reservation, the operating vehicle is added to the queue;

[0007] Recommending a warehouse area, warehouse location, and work point for the work based on the work information of the work task corresponding to the work vehicle, and adding the work vehicle to the work point queue corresponding to the work point;

[0008] For multiple storage areas where the work points do not interfere with each other, set up an independent queue of size 2 for each work point in the storage area, and dispatch the work vehicles in the work point queue corresponding to the corresponding work point based on the independent queue of each work point;

[0009] For multiple storage areas where work points interfere with each other, a shared queue of size 2 is set for the entry work points of the multiple storage areas, and a shared queue of size 2 is set for the exit work points. The work vehicles in the work point queue corresponding to each entry work point are dispatched based on the shared queue corresponding to the entry work point, and the work vehicles in the work point queue corresponding to each exit work point are dispatched based on the shared queue corresponding to the exit work point.

[0010] According to the present invention, a scheduling method for multi-span crossing operations in a steel coil warehouse is provided, which schedules operating vehicles in the operating point queues corresponding to each type of operating point based on a shared queue corresponding to any type of operating point, including:

[0011] Poll the shared queues corresponding to the work points of each corresponding type. If there are two groups of work vehicles in the shared queue, end the current polling; if there is a group of work vehicles in the shared queue, dispatch the group of work vehicles to the work points of each corresponding type, set the work status of the group of work vehicles to working, and synchronously dequeue the first work vehicle in the work point queue corresponding to each corresponding type of work point, combine the dequeued work vehicles into a new group of work vehicles, add them to the shared queue, and set the work status of the new group of work vehicles to waiting for work; if the shared queue is empty, synchronously dequeue the first work vehicle in the work point queue corresponding to each corresponding type of work point, combine the dequeued work vehicles into a new group of work vehicles, add them to the shared queue, and set the work status of the new group of work vehicles to waiting for work;

[0012] When a group of scheduled working vehicles completes the steel coil operation, the group of working vehicles is removed from the shared queue.

[0013] According to a scheduling method for multi-span crossing operations in a steel coil warehouse provided by the present invention, the first operating vehicle in the operating point queue corresponding to each corresponding type of operating point is synchronously dequeued, the dequeued operating vehicles are combined into a new group of operating vehicles and added to the shared queue, and the operating status of the new group of operating vehicles is set to waiting for operation, including:

[0014] If the operation point queue corresponding to any corresponding type of operation point is empty, determining whether the number of operation vehicles in the operation point queue corresponding to another operation point belonging to the same depot area as the corresponding type of operation point is greater than a preset value;

[0015] If the number of working vehicles in the working point queue corresponding to the other working point is greater than a preset value, the first working vehicle in the working point queue corresponding to the other working point is dequeued.

[0016] According to a scheduling method for multi-span travel operations in a steel coil warehouse provided by the present invention, the method of scheduling the operating vehicles in the operating point queue corresponding to the corresponding operating point based on the independent queue of each operating point includes:

[0017] Poll the independent queue of any work point. If there are two work vehicles in the independent queue, end the current polling. If there is one work vehicle in the independent queue, dispatch the work vehicle to the any work point, set the work vehicle's work status to working, dequeue the first work vehicle in the work point queue corresponding to any work point, add the dequeued work vehicle to the independent queue, and set the work status of the dequeued work vehicle to waiting for work. If the independent queue is empty, dequeue the first work vehicle in the work point queue corresponding to any work point, add the dequeued work vehicle to the independent queue, and set the work status of the dequeued work vehicle to waiting for work.

[0018] When the dispatched work vehicle completes the steel coil operation, the work vehicle is removed from the independent queue.

[0019] According to a scheduling method for multi-span crossing operations in a steel coil warehouse provided by the present invention, the warehouse area, warehouse location, and operation point for operation are recommended based on the operation information of the operation task corresponding to the operation vehicle, including:

[0026] Based on the residence period of the same type of steel coils whose corresponding owners are located on the top layer in all storage locations of the storage area where the operation is performed, and the residence period of the steel coils to be stored, the storage location for the operation is recommended; the residence period of any steel coil will gradually decrease as the steel coil is put into storage.

[0028] Determine the consignor's consignment continuity score based on the consignor's consignment information within a preset time period; the consignment information includes the consignor's consignment frequency within the preset time period and the time interval between each consignment;

[0029] When the storage continuity score of the corresponding consignor is higher than a preset threshold, several storage locations adjacent to the storage locations storing the steel coils of the corresponding consignor in the storage area where the operation is performed are locked within a preset time window.

[0045] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0046] Figure 1 This is a flow chart of the scheduling method for multi-span operation of a steel coil warehouse provided by the present invention, as shown in FIG. Figure 1 As shown, the method includes:

[0047] Step 110: Acquire the working vehicles in the queue and determine the working information corresponding to the working vehicles; wherein, after any working vehicle enters the park through reservation, the working vehicle is added to the queue;

[0048] Step 120: recommending a warehouse area, warehouse location, and work point for the work based on the work information of the work task corresponding to the work vehicle, and adding the work vehicle to the work point queue corresponding to the work point;

[0049] Step 130: For multiple storage areas where the work points do not interfere with each other, set up an independent queue of size 2 for each work point in the storage area, and schedule the work vehicles in the work point queue corresponding to the corresponding work point based on the independent queue of each work point;

[0050] Step 140: For multiple storage areas where the work points interfere with each other, a shared queue of size 2 is set for the entry work points of the multiple storage areas, and a shared queue of size 2 is set for the exit work points. The work vehicles in the work point queue corresponding to each entry work point are dispatched based on the shared queue corresponding to the entry work point, and the work vehicles in the work point queue corresponding to each exit work point are dispatched based on the shared queue corresponding to the exit work point.

[0051] Here, customers submit appointments for steel coil storage or steel coil pickup through the appointment management module. When a vehicle (steel coil storage or pickup) arrives at the park, the access control module automatically identifies the license plate number and allows the vehicle entry. The system also records the vehicle's entry time and adds it to the end of the queue for dispatch. Subsequently, starting from the head of the queue, the system progressively retrieves the vehicles in the queue and determines the corresponding operation information. Next, based on the vehicle's corresponding operation task information (such as the coil name), combined with the storage location information and the physical location of the operation point, the system recommends the storage area, storage location, and operation point for the vehicle to perform the operation. The vehicle is then added to the end of the operation point queue corresponding to the recommended operation point in the recommended storage area.

[0052] In some embodiments, during the storage area, storage location, and work point recommendation stage, storage areas for operations can be recommended based on the coil product name information in the operation information, combined with the product name information configured for each storage area. The order of storage area recommendations follows the principle of indoor storage first, followed by outdoor storage, with indoor storage recommended first, followed by manned storage. Furthermore, for vehicles performing incoming storage operations, storage areas storing coils of the same type and belonging to the same owner can be recommended based on the coil product name and owner information in the operation information, combined with the product name information configured for each storage area and the owner of the stored coils. For vehicles performing outgoing storage operations, storage areas storing coils of the same type belonging to the same owner can be recommended based on the coil product name and owner information in the operation information. Recommendations for unmanned storage must also meet the operational requirements for unmanned vehicles, and are generally controlled based on the outer diameter of the coil and the height of the storage room. After the storage area recommendations, storage area information for the operating vehicle is generated.

[0053] When the operation task corresponding to the operation vehicle is to put steel coils into storage, it can be recommended according to the principle of proximity to the same owner, first the first floor and then the second floor, and the weight of the second floor steel coils being less than the weight of the first floor steel coils. At the same time, combined with the pick-up appointment information, it is prohibited to place steel coils on the upper layer of the steel coils that have been reserved for pick-up. Specifically, the storage location for the operation can be recommended based on the owner information in the operation information, combined with the steel coil information stored in each storage location in the storage area where the operation is performed and the pick-up appointment information. In other embodiments, based on the owner information, the outbound time and single outbound quantity of the steel coils of the same type as the steel coils to be stored in the pick-up information of the corresponding owner within a preset time period can be retrieved, and then the residence period of the steel coils to be stored can be estimated based on the outbound time and single outbound quantity of the steel coils of the same type as the steel coils to be stored, as well as the number of steel coils of the same type as the steel coils to be stored located at the top layer in the storage area where the operation is recommended. The residence period of the steel coils to be stored can be calculated based on a pre-trained residence period prediction model. This residence period prediction model can be constructed using a recurrent neural network and trained based on a pre-collected training sample set. The training sample set includes the departure time and single departure quantity of the same type of steel coils as the corresponding shipper's pick-up information within a preset time period when the steel coil is first stored, the number of the same type of steel coils located on the top layer of the same storage area, and the actual residence time of the steel coil in the storage area.

[0054] The recommended storage location for the operation is based on the residence period of the same type of steel coils whose corresponding owners are located on the top layer of all the storage locations in the storage area where the operation is recommended, as well as the residence period of the steel coils to be stored. The residence period of any steel coil will gradually decrease as the steel coil enters the storage time. Here, the storage location where the residence period of the same type of steel coils whose corresponding owners are located on the top layer in the storage area is longer than the residence period of the steel coils to be stored can be selected for recommendation. In this way, the steel coils on the lower layer can be prevented from being buried for a long time, resulting in long-term obstruction of their outbound path, thereby minimizing the cost of moving and the complexity of scheduling, thereby improving the efficiency of steel coil outbound. In addition, when the residence period of a steel coil is reduced to a preset value, when a new steel coil is stored near it, the steel coil can be hoisted to a preset buffer zone by taking advantage of the empty state of the crane during the return trip for subsequent outbound delivery.

[0055] It should be noted that in order to facilitate the placement of steel coils of the same consignor nearby, the warehousing trends of high-frequency consignors can be dynamically identified, and flexible space can be reserved near the current warehousing task to achieve local centralized storage. Specifically, after recommending the warehouse location for the operation based on the residence period of the same type of steel coils of the corresponding consignor located on the top layer of all the warehouse locations in the warehouse area where the operation is performed, and the residence period of the steel coils to be stored, the warehousing continuity score of the corresponding consignor can also be determined based on the warehousing information of the corresponding consignor within a preset time period. Among them, the warehousing information includes the warehousing frequency of the corresponding consignor within the preset time period and the time interval between each warehousing. For example, the variance of the time interval between each warehousing of the corresponding consignor within the preset time period can be determined, and the ratio of the preset coefficient to the variance, the average value of the time interval between each warehousing of the corresponding consignor within the preset time period and the warehousing frequency can be used as the warehousing continuity score of the corresponding consignor. If the consignor's warehousing continuity score exceeds a preset threshold, several storage locations within the recommended storage area that are adjacent to the location storing the consignor's coils can be locked for a preset time window. In other words, these locations will no longer be recommended to vehicles handling coils from other consignors within the preset time window.

[0056] When the operation task corresponding to the operation vehicle is to ship out steel coils, based on the steel coil information stored in each storage location in the storage area where the operation is performed, the storage location where the steel coil of this type is located on the top layer is determined and recommended as the storage location to be operated.

[0057] Finally, based on the physical location of the recommended storage area and the physical locations of each operation point in the storage area, the operation point can be recommended according to the principle of the shortest average lifting distance.

[0058] During the operation vehicle scheduling phase, the system forms a scheduling queue based on the configuration information of the park's storage areas and work points, and adopts two scheduling methods: independent queues and shared queues, combining timed polling and special processing logic to perform vehicle scheduling. Specifically, for multiple storage areas where the work points do not interfere with each other, an independent queue of size 2 is set for each work point in these storage areas, and the operation vehicles in the work point queue corresponding to the corresponding work point are scheduled based on the independent queue of each work point. For multiple storage areas where the work points interfere with each other (there is no interference between different work points in the same storage area), a shared queue of size 2 is set for all the inbound work points in these storage areas, and a shared queue of size 2 is set for all the outbound work points. In this way, the operation vehicles in the work point queue corresponding to each inbound work point are scheduled based on the shared queue corresponding to the inbound work point, and the operation vehicles in the work point queue corresponding to each outbound work point are scheduled based on the shared queue corresponding to the outbound work point.

[0059] In some embodiments, for a shared queue scheduling strategy, for multiple storage areas with interfering work points, the shared queue corresponding to each corresponding type of work point (inbound work point or outbound work point) is polled. If two groups of work vehicles exist in the shared queue, the current polling is terminated. If a group of work vehicles exists in the shared queue, the group of work vehicles is dispatched to each corresponding type of work point, and the work status of the group of work vehicles is set to "in-use". The first work vehicle in the work point queue corresponding to each corresponding type of work point is then dequeued, and the dequeued work vehicles are combined into a new group of work vehicles, added to the shared queue, and the work status of the new group of work vehicles is set to "pending". If the shared queue is empty, the first work vehicle in the work point queue corresponding to each corresponding type of work point is dequeued, and the dequeued work vehicles are combined into a new group of work vehicles, added to the shared queue, and the work status of the new group of work vehicles is set to "pending". When a dispatched group of work vehicles completes the steel coil inbound or outbound operation, the group of work vehicles is dequeued from the shared queue.

[0060] like Figure 2 As shown in the figure, assuming that there is interference between the work points in the three warehouse areas (manned warehouse, unmanned warehouse A, and unmanned warehouse B), but no interference between different work points in the same warehouse area, for this type of warehouse area, the three work points of the same type in the three warehouse areas are merged into a shared queue for scheduling. That is, the inbound work points in the three warehouse areas (manned warehouse, unmanned warehouse A, and unmanned warehouse B) are merged into a shared queue for scheduling, and the outbound work points in the three warehouse areas (manned warehouse, unmanned warehouse A, and unmanned warehouse B) are merged into a shared queue for scheduling. The size of each shared queue is 2, which means that three vehicles are kept in operation and three vehicles are waiting for work, and three vehicles are dispatched at a time. During actual scheduling, for any shared queue, when the number of vehicle groups N in the shared queue is 2, the polling is terminated; when N is less than 2, if N is 1, the status of the three vehicles in the group is updated to working, and the three working points corresponding to the shared queue are used as conditions to obtain the first vehicle combination in the working point queue corresponding to each working point as a new working vehicle group, add it to the queue, and update the status of the working vehicle group to waiting for work; if N is 0, the three working points corresponding to the shared queue are used as conditions to obtain the first vehicle combination in the working point queue corresponding to each working point as a new working vehicle group, add it to the queue, and update the status of the working vehicle group to waiting for work.

[0061] When synchronously dequeuing the first operating vehicle from the work point queue corresponding to each corresponding type of work point, if the work point queue corresponding to any corresponding type of work point is empty, a determination is made as to whether the number of operating vehicles in the work point queue corresponding to another work point in the same depot as the corresponding type of work point is greater than a preset value. If the number of operating vehicles in the work point queue corresponding to the other work point is greater than the preset value, the first operating vehicle in the work point queue corresponding to the other work point is dequeued.

[0062] For independent queues, this type of scheduling strategy, such as Figure 3 As shown, for multiple storage areas where work points do not interfere with each other, the independent queue of any work point can be polled. If there are two work vehicles in the independent queue, the current polling is terminated; if there is a work vehicle in the independent queue, the work vehicle is dispatched to the work point, the work status of the work vehicle is set to working, and the first work vehicle in the work point queue corresponding to the work point is dequeued, the dequeued work vehicle is added to the independent queue, and the work status of the dequeued work vehicle is set to waiting for work; if the independent queue is empty, the first work vehicle in the work point queue corresponding to the work point is dequeued, the dequeued work vehicle is added to the independent queue, and the work status of the dequeued work vehicle is set to waiting for work.

[0063] When dequeuing the first working vehicle from the work point queue corresponding to any work point, if the work point queue corresponding to that work point is empty, the system determines whether the number of working vehicles in the work point queue corresponding to another work point in the same storage area as the work point is greater than a preset value. If the number of working vehicles in the work point queue corresponding to the other work point is greater than the preset value, the first working vehicle in the work point queue corresponding to the other work point is dequeued and added to the independent queue of the work point. After the working vehicle completes the steel coil operation, the working vehicle status is updated to "operation completed" and the working vehicle is dequeued from the independent queue.

[0064] If a vehicle has completed its work at a specific location and has other work locations to complete, it will be added to the queue for that location and await dispatch. After completing all operations, the vehicle will automatically exit the park after its license plate number is identified by the access control automatic recognition device.

[0065] To sum up, the method provided by the embodiment of the present invention recommends the warehouse area, warehouse location and work point for operation through the operation information of the operation task corresponding to the operation vehicle, and adds the operation vehicle to the work point queue corresponding to the corresponding work point, so that for multiple warehouse areas where the work points do not interfere with each other, an independent queue of size 2 is set for each work point in the warehouse area, and the operation vehicles in the work point queue corresponding to the corresponding work point are scheduled based on the independent queue of each work point; for multiple warehouse areas where the work points interfere with each other, a shared queue of size 2 is set for the entry work points of multiple warehouse areas, and a shared queue of size 2 is set for the exit work point, and the operation vehicles in the work point queue corresponding to each entry work point are scheduled based on the shared queue corresponding to the entry work point, and the operation vehicles in the work point queue corresponding to each exit work point are scheduled based on the shared queue corresponding to the exit work point, thereby realizing intelligent scheduling and control of multi-span crossing operations.

[0066] The scheduling system for multi-span passing operations in a steel coil warehouse provided by the present invention is described below. The scheduling system for multi-span passing operations in a steel coil warehouse described below and the scheduling method for multi-span passing operations in a steel coil warehouse described above can be referred to each other.

[0067] Based on any of the above embodiments, Figure 4 This is a structural diagram of the scheduling system for multi-span travel operations in a steel coil warehouse provided by the present invention. Figure 4 As shown, the system includes:

[0068] The operation vehicle acquisition unit 410 is used to acquire the operation vehicles in the queue and determine the operation information corresponding to the operation vehicles; wherein, after any operation vehicle enters the park through reservation, the operation vehicle is added to the queue;

[0069] The work location recommendation unit 420 is used to recommend a warehouse area, warehouse location and work point for the work based on the work information of the work task corresponding to the work vehicle, and add the work vehicle to the work point queue corresponding to the work point;

[0070] The first vehicle dispatching unit 430 is configured to set up an independent queue of size 2 for each work point in a storage area where the work points do not interfere with each other, and dispatch the work vehicles in the work point queue corresponding to the corresponding work point based on the independent queue of each work point;

[0071] The second vehicle dispatching unit 440 is used to set a shared queue of size 2 for multiple entry work points in the storage area where work points interfere with each other, and set a shared queue of size 2 for multiple exit work points in the storage area, and dispatch the work vehicles in the work point queue corresponding to each entry work point based on the shared queue corresponding to the entry work point, and dispatch the work vehicles in the work point queue corresponding to each exit work point based on the shared queue corresponding to the exit work point.

[0072] The system provided by the embodiment of the present invention recommends warehouse areas, warehouse locations and work points for operations through the work information of the work tasks corresponding to the work vehicles, and adds the work vehicles to the work point queues corresponding to the corresponding work points, so that for multiple warehouse areas where the work points do not interfere with each other, an independent queue of size 2 is set for each work point in the warehouse area, and the work vehicles in the work point queues corresponding to the corresponding work points are dispatched based on the independent queues of each work point; for multiple warehouse areas where the work points interfere with each other, a shared queue of size 2 is set for the entry work points of the multiple warehouse areas, and a shared queue of size 2 is set for the exit work points, and the work vehicles in the work point queues corresponding to the entry work points are dispatched based on the shared queues corresponding to the entry work points, and the work vehicles in the work point queues corresponding to the exit work points are dispatched based on the shared queues corresponding to the exit work points, thereby realizing intelligent scheduling and control of multi-span crossing operations.

[0073] Based on any of the above embodiments, scheduling the working vehicles in the working point queues corresponding to the respective working points of any type based on the shared queue corresponding to the working point of any type includes:

[0074] Poll the shared queues corresponding to the work points of each corresponding type.
