[0001] This invention relates to the field of warehouse management technology, and in particular to a method for comprehensive scheduling of various logistics vehicles for raw tobacco. Background Technology

[0002] In the process of handing over raw tobacco to industrial and commercial enterprises, the most common approach is to unload the tobacco centrally, load it into frames and then onto trucks, and then transport it to warehouses in a decentralized manner. The logistics vehicles involved include stand-on pallet trucks, forklifts, and tractors. There are many types of vehicles, different unloading progresses, different distances between warehouses and unloading points, and many batches and grades of tobacco being unloaded, which involves a relatively complex scheduling strategy.

[0047] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0048] like Figure 1 and Figure 2 As shown, the integrated scheduling method for multiple logistics vehicles for raw tobacco provided in this embodiment includes the following steps in actual implementation:

[0049] Step S1: The unloading line automatically tracks the unloading progress and automatically writes the unloading information into the radio frequency identification (RFID) tag of the actual smoke frame.

[0050] In this invention, all tobacco frames are equipped with RFID tags, and readers / writers are installed on the transport vehicles (forklifts, electric vehicles, AGVs) described in detail later. In one embodiment of this invention, 10 unloading lines are constructed at the tobacco collection shed. In one embodiment of the comprehensive scheduling method for multiple logistics vehicles for raw tobacco of this invention, step S1 may specifically include:

[0051] Step S11: The scheduling system allocates unloading lines to perform unloading tasks according to the preset unloading allocation strategy.

[0052] After the tobacco trucks register at the check-in room (arriving in chronological order), they are assigned to the corresponding unloading lines. The pre-defined unloading allocation strategy specifically includes: prioritizing the unloading line with the shortest queue; if multiple lines have the shortest queue, one is randomly selected to perform the unloading task. Currently, with 10 unloading lines, if unloading vehicles are allocated according to a pre-defined order (e.g., by number from largest to smallest, or smallest to largest), some lines will inevitably have a consistently higher workload than others. For example, if allocated by number 1 to 10, and 35 trucks arrive today, the allocation result will be lines 1-5 unloading 4 trucks, while lines 6-10 will only unload 3 trucks. Using the unloading allocation strategy of this invention can balance the workload of each unloading line.

[0053] Step S12: After receiving the unloading task, the unloading line automatically collects the unloading information, automatically counts the unloading information, and automatically writes the unloading information into the radio frequency identification tag of the actual smoke frame.

[0054] After receiving the tobacco unloading task, the unloading line automatically collects unloading information and uses an automatic counting function to reflect the unloading progress in real time, and automatically writes the unloading information into the RFID tag of the frame. In practice, the unloading line operator places the tobacco packs on the conveyor belt and completes the framing at the unloading line exit. Typically, one frame holds 16 packs of tobacco. After the frame is full, the process proceeds to step S2.

[0055] Step S2: Based on the unloading progress of the cigarettes, assign tasks to each stand-on pallet truck. After receiving the temporary storage task, the stand-on pallet truck will transport the cigarette frames to the corresponding storage location in the temporary storage area.

[0056] The pallet truck, which can be either a pump truck or a forklift, is not specifically limited to this invention. Its function is to transport full-loaded crates of cigarettes to the temporary storage area of ​​the unloading line. In one embodiment of the comprehensive scheduling method for multiple logistics vehicles for raw cigarettes of the present invention, step S2 may specifically include:

[0057] Step S21: After the actual cigarette frame is removed from the production line, a completion instruction is sent to the scheduling system.

[0058] Step S22: The scheduling system automatically assigns sorting tasks to the corresponding stand-on pallet trucks according to the idle status of the stand-on pallet trucks and the buffer quantity of the cigarette frames on the unloading line, in accordance with a preset temporary storage allocation strategy. This allows each stand-on pallet truck to execute the sorting tasks in sequence, moving the frames loaded from the corresponding cigarette receiving line to the corresponding temporary storage location.

[0059] The preset temporary storage allocation strategy specifically includes:

[0060] Prioritize selecting the pallet truck with the fewest unexecuted temporary storage tasks to move the corresponding cigarette receiving line loading frames to the unloading buffer area with the least amount of actual cigarette frames. If there are multiple pallet trucks with the fewest unexecuted temporary storage tasks, randomly select one of them to perform the temporary storage task. If there are multiple unloading buffer areas with the least amount of actual cigarette frames, randomly select one of them to serve as the unloading buffer area for the temporary cigarette frames.

[0061] Step S23: Dynamically update the storage area location status based on the task execution status of each stand-on pallet truck.

[0062] Step S2 allows for the scientific scheduling of ride-on pallet trucks, ensuring that different varieties, origins, and grades of tobacco leaves are accurately and quickly transported to their respective temporary storage locations.

[0063] Step S3: At least based on the temporary storage area location, the distance to the corresponding warehouse, and the tractor's work tasks, assign tasks to each tractor and each loading forklift. After receiving the loading task, the loading forklift loads the full cigarette crates from the corresponding temporary storage area location onto the corresponding tractor.

[0064] Once a certain quantity of cigarette crates has accumulated in the temporary storage area, a loading forklift loads the crates onto a tractor unit. The tractor unit can be, for example, an electric vehicle; this invention does not specifically limit this. In one embodiment of the comprehensive scheduling method for multiple logistics vehicles of raw cigarettes according to this invention, in step S3, tasks are assigned to each tractor unit and each loading forklift based on the temporary storage area's location, the distance to the corresponding warehouse, and the tractor unit's operational tasks. Upon receiving a loading task, the loading forklift loads the full cigarette crates from the corresponding temporary storage area location onto the corresponding tractor unit. Step S3 may specifically include:

[0065] Step S31: Set the temporary storage area location status as the first priority, the tractor operation task status as the second priority, and the warehouse distance status as the third priority, and set different weights for different priorities.

[0066] Step S32: The dispatching system automatically assigns tasks to the tractor and loading forklift according to priority. The tractor stops at the corresponding receiving platform according to the task, and the loading forklift loads the full cigarette boxes in the corresponding temporary storage area to the corresponding tractor according to the loading task.

[0067] In practice, the dispatching system automatically assigns tasks to the onboard terminal of the tractor and the terminal of the loading forklift, and pushes the tasks to the corresponding tractor and loading forklift. The tractor stops at the corresponding receiving platform according to the task, and the forklift driver loads the full smoke frames of the corresponding temporary storage area onto the corresponding tractor according to the task.

[0068] In another embodiment of the integrated scheduling method for multiple logistics vehicles of raw tobacco of the present invention, in step S3, tasks are assigned to each tractor and each loading forklift based on the temporary storage area location, the distance to the corresponding warehouse, the tractor's work tasks, the warehouse centralized warehousing tasks, the batch of tobacco unloaded at the corresponding unloading line, and other factors. After receiving the loading task, the loading forklift loads the full tobacco frames from the corresponding temporary storage area location onto the corresponding tractor. At this time, step S3 may specifically include:

[0069] Step S31': Set the temporary storage area location status as the first priority, the tractor operation task status as the second priority, the warehouse distance status as the third priority, the warehouse centralized warehousing task status as the fourth priority, the corresponding batch of unloaded tobacco on the unloading line as the fifth priority, and other factors as the sixth priority, and set different weights for different priorities.

[0070] Other factors include weather factors, personnel factors, etc.

[0071] Step S32': The dispatching system automatically assigns tasks to the tractor and loading forklift according to priority. The tractor stops at the corresponding receiving platform according to the task, and the loading forklift loads the full cigarette boxes from the corresponding temporary storage location onto the corresponding tractor according to the loading task.

[0072] Step S3 allows for the scientific scheduling of loading forklifts, ensuring timely and accurate loading from the corresponding temporary storage location to the appropriate tractor.

[0073] Step S4: Based on the previous warehouse location planning and the information on the cigarette frames to be transported, the tractor will navigate and transport the loaded cigarette frames to the corresponding warehouse according to the preset route strategy.

[0074] Once the tractor is fully loaded (one tractor typically carries 20 frames), it is transported to the entrance of the pre-designated raw tobacco warehouse. Specifically, based on the prior warehouse location planning and the information of the tobacco frames being transported, the dispatching system automatically assigns and sorts tasks to the corresponding tractor, enabling the tractor to execute tasks according to the sorting order and navigate and transport the loaded tobacco frames to the entrance of the corresponding warehouse according to the preset route strategy.

[0075] The preset route strategy specifically includes: calculating and saving the shortest paths from the tobacco collection shed to each warehouse within the storage facility using Dijkstra's algorithm, Floyd's algorithm, or SPFA algorithm; if the roads within the facility change, the existing paths are deleted first, then the road information is updated, and the shortest paths from the tobacco collection shed to each warehouse within the storage facility are recalculated. In this invention, Dijkstra's algorithm is preferred. It should be noted that this invention does not specifically limit the algorithm used to determine the shortest paths from the tobacco collection shed to each warehouse within the storage facility.

[0076] In practice, after the dispatching system assigns sorted tasks to the corresponding station tractors, the drivers execute the tasks according to the sorted order, navigating and transporting the goods to the entrance of the corresponding warehouse. Through step S4, tractors can be scientifically dispatched, the workload balanced, and the rapid and accurate transport of goods from the unloading point to the corresponding warehouse can be ensured.

[0077] Step S5: Unloading and Warehousing. The forklift, based on the storage location plan and the tractor's work tasks, will move the cigarette crates transported by the tractor into the corresponding storage location, thus completing the warehousing operation.

[0078] In some embodiments of this invention, the unloading and warehousing forklift can also be an AGV (Automated Guided Vehicle), whose function is to transport the cigarette crates (usually two crates at a time) from the warehouse entrance to a pre-designated warehouse aisle. Specifically, after the tractor arrives at the warehouse entrance and takes its position, the scheduling system automatically generates production task information and automatically assigns tasks to the corresponding unloading and warehousing forklifts based on the forklift's operating status, the warehouse's centralized warehousing task status, and waiting time. After receiving the unloading and warehousing task, the forklift, according to the storage location planning and the tractor's operating task status, puts the cigarette crates transported by the tractor into the corresponding storage location, completing the warehousing operation.

[0079] In one embodiment of the integrated scheduling method for multiple logistics vehicles for raw tobacco of the present invention, step S5 may specifically include:

[0080] Step S51: Set the forklift operation status as the first priority, the waiting time as the second priority, and the warehouse centralized inbound task status as the third priority, and set different weights for different priorities.

[0081] Step S52: The scheduling system automatically assigns tasks to the corresponding unloading and warehousing forklifts according to priority. After receiving the unloading and warehousing task, the forklifts will put the cigarette frames carried by the tractor into the corresponding storage location according to the storage location planning and the tractor's operation task, thus completing the warehousing operation.

[0082] In practice, after the tractor unit is in position, the user clicks to complete the task on the onboard terminal. The dispatching system automatically generates task information and pushes it to the corresponding unloading and warehousing forklift terminal. After receiving the unloading and warehousing task, the forklift, based on the storage location planning and the tractor unit's operational task, places the cigarette crates being transported by the tractor unit into the corresponding storage location, completing the warehousing operation. Through step S5, warehousing forklifts can be scientifically dispatched, ensuring timely and accurate transport of the cigarette crates from the tractor unit to the corresponding storage location based on the tractor unit's arrival status.

[0083] In one embodiment of this invention, an industrial control computer (Windows 10 operating system) is installed on each unloading line. The operator selects the vehicle and its class currently being unloaded (typically, a tobacco truck carries multiple classes; assuming the current unloading line is line 1, class is C3F, and the storage warehouse is warehouse 1) on the unloading control desktop program, and then selects the corresponding unloading buffer area (assuming zone 1-1). Based on this, the background scheduling system will generate four tasks:

[0084] Task 1: Pick up the frame at the exit of Line 1, place the frame at Zone 1-1, and use the following vehicles: stand-on pallet truck (can be a pump truck) or loading forklift.

[0085] Task 2: Picking location: Zone 1-1; Placing location: Towing vehicle (can be electric vehicle); Applicable vehicle: Unloading and warehousing forklift.

[0086] Task 3: Pick up the frame in Zone 1-1, place the frame at the entrance of Warehouse 1, applicable vehicle: tractor (can be an electric vehicle).

[0087] Task 4: Pick up the frame at the entrance of Warehouse 1; place the frame in each aisle of Warehouse 1; applicable vehicles: unloading and warehousing forklifts and AGVs.

[0088] The comprehensive scheduling method for various logistics vehicles in the raw tobacco industry provided by this invention provides scientific scheduling for stand-on pallet trucks, ensuring accurate and rapid transport of tobacco leaves of different varieties, origins, and grades to corresponding temporary storage locations. This method is applicable to most logistics vehicle scheduling scenarios in comprehensive industrial parks. It also provides scientific scheduling for loading forklifts, ensuring timely and accurate loading from corresponding temporary storage locations to the appropriate tractor. Furthermore, it provides scientific scheduling for tractor trucks, balancing workloads and ensuring rapid and accurate transport from unloading points to corresponding warehouses. Finally, it provides scientific scheduling for inbound forklifts, ensuring timely and accurate transport of the tobacco leaves from the tractor to the appropriate storage location based on the tractor's availability. This method enables the execution of scheduling strategies for different logistics vehicles in different operating scenarios, handling multiple batches of tobacco leaves. It achieves comprehensive scheduling of multiple logistics vehicles, multiple business processes, and multiple batches of materials, and allows for dynamic strategy adjustments based on different business situations. This effectively improves the smoothness of the entire logistics operation, increases the efficiency of logistics vehicle operation, reduces the difficulty and cost of manual scheduling, and ensures scientific, efficient, and accurate scheduling of raw tobacco inbound processes.

The method for integrated scheduling of multiple logistics vehicles for raw tobacco as described in claim 1, characterized in that, The process involves assigning tasks to each tractor and loading forklift based on at least the availability of storage locations in the temporary storage area, the distance to the corresponding warehouse, and the tractor's operational tasks. Upon receiving a loading task, the loading forklift loads the full cigarette crates from the corresponding storage location onto the corresponding tractor. This specifically includes: The status of temporary storage locations is set as the first priority, the status of tractor operation tasks is set as the second priority, and the warehouse distance is set as the third priority, with different weights assigned to different priorities; The dispatching system automatically assigns tasks to tractor trucks and loading forklifts based on priority. Tractor trucks park at the corresponding receiving platform according to the task, and loading forklifts load the full cigarette crates from the corresponding temporary storage area onto the corresponding tractor truck according to the loading task.

7. The method for integrated scheduling of multiple logistics vehicles for raw tobacco as described in claim 1, characterized in that, The tractor unit, based on the prior warehouse location planning and the information of the cigarette crates being transported, navigates and transports the loaded cigarette crates to the corresponding warehouse according to a preset route strategy, specifically including: Based on the prior warehouse location planning and the information on the cigarette crates to be moved, the dispatching system automatically assigns sorting tasks to the corresponding station tractors, so that the tractors can execute tasks according to the sorting order and navigate and move the loaded cigarette crates to the entrance of the corresponding warehouse according to the preset route strategy.

8. The method for comprehensive scheduling of multiple logistics vehicles for raw tobacco as described in claim 7, characterized in that, The preset route strategy specifically includes: Calculate and save the shortest paths from the tobacco collection shed to each warehouse within the storage facility using Dijkstra's algorithm, Floyd's algorithm, or SPFA algorithm. If the roads within the factory area change, the existing paths will be deleted first, the road information will be updated, and then the shortest paths from the tobacco collection shed to the storage warehouses within the factory area will be recalculated.

9. The method for comprehensive scheduling of multiple logistics vehicles for raw tobacco as described in claim 1, characterized in that, The unloading and warehousing forklift, based on the storage location planning and the towing vehicle's operational tasks, will place the smoke frames transported by the towing vehicle into the corresponding storage location, completing the warehousing operation. This specifically includes: After the tractor arrives at the warehouse entrance and takes its position, the dispatching system automatically generates production task information and automatically assigns tasks to the corresponding unloading and warehousing forklifts based on forklift operation status, warehouse centralized warehousing task status, and waiting time. After receiving the unloading and warehousing task, the forklifts, according to the storage location planning and the tractor's operation task status, store the cigarette crates transported by the tractor into the corresponding storage location, completing the warehousing operation, which specifically includes: Set forklift operation status as priority 1, waiting time as priority 2, and warehouse centralized inbound task status as priority 3, and assign different weights to different priorities; The dispatching system automatically assigns tasks to the corresponding unloading and warehousing forklifts based on priority. After receiving the unloading and warehousing task, the forklift will place the cigarette crates carried by the tractor into the corresponding storage location according to the storage location plan and the tractor's operation task, thus completing the warehousing operation.
