A rapid outbound control method for three-dimensional warehousing of electric power materials

Abstract

The present invention discloses a rapid outbound control method for three-dimensional storage of electric power materials, which relates to the technical field of electric power material storage. By statistically analyzing the outbound frequency and correlation of each material, the materials with high outbound frequency are preferentially placed in the storage locations convenient for outbound, and the materials with associated outbound are placed in adjacent areas. Based on the outbound convenience weights of attributes such as the number of warehouse levels, row positions, and column positions, the storage locations of materials are optimized. There are Class I and Class II buffer areas inside the warehouse. The Class I buffer area is used for preprocessing the outbound of materials, and the Class II buffer area is used for temporarily storing materials according to emergencies such as weather. After the WMS system generates an outbound task order, the WCS system moves the materials from the storage location to the Class I buffer area through the minimum path algorithm and updates the material correlation record form. An outbound prediction order is generated according to the weather information and historical data, and after being reviewed by the administrator, it is issued to the WCS system to move the materials in the prediction order to the Class II buffer area in advance to improve the outbound efficiency.

Description

Technical Field

[0001] The present invention relates to the technical field of electric power material storage, and particularly relates to a rapid out - warehouse control method for three - dimensional storage of electric power materials. Background Art

[0002] Electric power inventory materials are the main supply guarantee forms for operation and maintenance materials such as electric power maintenance and emergency repair, and are crucial for supporting the large - scale maintenance system of electric power companies. With the continuous expansion of the scale of electric power material inventory management and the increasing requirements for refined management, the requirements for the standardization and regularization of warehouse management have also increased. The traditional manual warehouse operation mode and data collection method can no longer meet the requirements of modern warehouse management, affecting work efficiency and becoming an obstacle restricting the improvement of electric power warehousing management level. As one of the main inventory methods, the automated stereoscopic warehouse can effectively save warehouse space, increase storage capacity, and improve the access efficiency of goods, thus helping to strengthen business operation and management capabilities.

[0003] The prior art such as CN110175798A discloses a method for operating a warehousing system based on a mobile application. The method includes: establishing a warehousing system and an ERP system, performing inbound, outbound, inventory counting, transfer, and in - warehouse goods transfer processes according to the warehousing system and the ERP system, and performing application integration with the ERP system to realize data synchronization and sharing of warehousing arrival information, in - warehouse information, and the ERP system. For outbound, the ERP system issues a material requisition form, an outbound order is generated in the warehousing system, and the outbound order is checked through an inspection process module to confirm whether wave picking is required. If so, a wave order is generated according to the wave strategy and then a picking order is generated according to the distribution strategy. If not, a picking order is directly generated according to the distribution strategy. After picking, it is checked whether the picking order is completed. After confirmation through the inspection process module, a shipping order is generated, and after confirming the shipping order, the goods are put on the shelf.

[0004] Although the prior art has realized the informatization and automation of warehousing management to a certain extent, there are still some defects and deficiencies in the three - dimensional storage of electric power materials:

[0005] 1. Unreasonable storage strategy: The existing storage strategies for three - dimensional storage of electric power materials mainly focus on finding the nearest available storage location or storing materials with the same attributes by area, without considering the outbound frequency of individual materials and the problem of rapid outbound of multiple materials, resulting in an increase in the number of relocations of three - dimensional storage materials and low outbound efficiency.

[0006] 2. Lack of pre - outbound method: The existing three - dimensional storage of electric power materials does not adopt a pre - outbound method, and outbound operations need to be carried out when personnel arrive at the warehousing site, which seriously restricts the outbound efficiency.

[0007] 3. Lack of dynamic adjustment: With the change of seasons, sudden weather and other situations, the outbound demand for power materials will change significantly. However, the existing three-dimensional storage of power materials does not dynamically adjust the storage of materials in the storage locations, which also greatly restricts the rapid outbound of power materials.

[0008] 4. Insufficient utilization of material correlation and seasonality: The usage frequencies of power materials vary. Some power materials are used frequently, while some are used only once in a long time, resulting in a large difference in the usage frequencies of power materials. The probability that materials shipped out together will be shipped out simultaneously in subsequent task orders is high. In addition, with the change of seasons, the demand quantity and types of power materials vary greatly. Different seasons and severe weather have different impacts on the power grid, and different power repair materials are required. The existing technologies fail to fully utilize this information for warehouse storage optimization.

[0009] Therefore, there is an urgent need for a convenient, time-saving and efficient outbound control method for the intelligent three-dimensional warehouse of power materials to improve the efficiency of outbound of goods in the warehouse. Abandoning the traditional warehouse management thinking, adopting an innovative warehouse management model, realizing the reasonable layout of warehouse storage resources, improving the warehouse management standards, comprehensively integrating resources, improving the efficient utilization of warehouse storage resources, and optimizing the business process of warehouse management are the inevitable trends of future warehouse management development. Summary of the Invention

[0010] The problem to be solved by the present invention is to propose a rapid outbound control method for the three-dimensional storage of power materials for the problems existing in the prior art, such as unreasonable storage strategies, lack of pre-outbound methods, lack of dynamic adjustment, and insufficient utilization of material correlation and seasonality.

[0011] To solve the above problems, the present invention provides a rapid outbound control method for the three-dimensional storage of power materials, including the following steps:

[0012] S1: Inbound of power materials:

[0013] S1-1: Through the warehouse control system, statistically analyze the outbound frequency and correlation of each material, give priority to placing the materials with high outbound frequency in the storage locations convenient for outbound, and place the materials with associated outbound in adjacent areas;

[0014] S1-2: Design of the outbound convenience weight for the three-dimensional warehouse storage locations: Based on the attributes such as the layer number, row position, and column position of the storage location, set the outbound convenience weight for each storage location;

[0015] The formula for the outbound convenience weight of the storage location is:

[0016] W LRC = W L + W R + W C ;

[0017] Among them, W LRC represents the weight of the convenience of outbound of the storage location (L, R, C). W L , W R , W C represent the weights of the layer number, row position, and column position respectively;

[0018] Update the weight of the convenience of outbound of the storage location according to the outbound probability and material correlation of the inbound materials:

[0019] W' LRC = W LRC + (P ij · weight increment) - ((1 - P ij )· weight decrement);

[0020] Among them, Pij represents the correlation probability of the materials, and the material numbers are represented by Wi and Wj;

[0021] S2: Pre - processing for the outbound of power materials:

[0022] S2 - 1: There is a buffer area inside the warehouse for storing the materials to be received soon. The applicant sends a requisition task order through a remote device, and the warehouse WCS control system automatically places the materials on the material list into the buffer area;

[0023] S2 - 2: The pre - processing process for the outbound of the three - dimensional warehouse:

[0024] After the WMS system generates a material outbound task order after approval, the WMS system sends the outbound task order to the WCS system; the WCS system generates a pre - processing work order according to the batch outbound material list and the minimum path algorithm; set the level - I buffer area and level - II buffer area of the three - dimensional storage location, where the level - I buffer area is used for the pre - processing of material outbound, and the level - II buffer area is used for the area where materials are temporarily placed according to emergencies such as weather; the WCS receives the outbound task order; checks the availability of the level - I buffer area; calls the minimum path algorithm for outbound, moves the task order materials from the storage location to the level - I buffer area; records the storage location of the materials on the material outbound order in the level - I buffer area; the WCS feedbacks that the pre - processing is completed and updates the material correlation record form.

[0025] S3: Selection of the minimum path for the outbound of power materials:

[0026] S3 - 1: Issue an outbound task through the remote device terminal, use intelligent analysis with multi - task parallelism for task optimization and scheduling, ensure the smooth operation of the conveying equipment, avoid collisions with any objects, and maximize work efficiency and logistics operation benefits;

[0027] S3-2: Utilize the refined decomposition of tasks and analysis of routes to intelligently specify the optimal picking location and realize automated minimum path selection to improve the speed and accuracy of loading and unloading goods.

[0028] S4: Dynamic adjustment of power material storage locations:

[0029] S4-1: Taking into account seasonal changes, weather forecasts, and project demand factors, dynamically adjust material storage locations, and move materials with a high probability of being shipped out in the near future to areas close to the export area to achieve rapid storage and warehousing operations;

[0030] S4-2: Intelligent robots are equipped in the three-dimensional storage warehouses for electric power materials to automatically collect important information such as weather that may affect the power grid. Based on previous learning experience, the intelligent robots generate a delivery forecast list and send it to the administrator for review. The administrator reviews the delivery forecast list and issues the electric power material delivery forecast list to the WCS system. The WCS system moves the materials from the storage location to the Level II cache area based on the delivery forecast list.

[0031] Preferably, the correlation analysis of materials in the power material warehousing in step S1 is based on the work demand material correlation and historical outbound correlation factors to obtain the material correlation probability, and the materials with high correlation probability are placed in physically adjacent areas to facilitate simultaneous outbound delivery.

[0032] Preferably, in the step S2, in the pre-processing of power material delivery, the goods and pallets are bound to data by using RFID / barcode information identification technology, so as to effectively control the flow status of the goods, and remind the applicant that the materials have arrived at the buffer storage location through SMS or system messages at the front end of the system.

[0033] Preferably, in the step S4, the dynamic adjustment of the power material storage location is combined with seasonal changes and sudden weather conditions to predict the materials that are urgently needed in the next few days, and the materials are placed in the buffer area to achieve rapid release from the warehouse during power repairs.

[0034] Preferably, in the S1 electric power material storage, the setting of the convenience weight of the storage location out of the storage also includes the following steps:

[0035] A. Increase the weight of the convenience of outbound delivery based on the location of the warehouse near the exit and the lane;

[0036] B. In multi-layer warehouses, the convenience weight of outbound storage at each level is designed according to the above method.

[0037] Preferably, the calculation formula for the frequency of power materials leaving the warehouse is:

[0038]

[0039] Among them, Fi represents the outbound frequency of material Wi, Ci represents the number of times of outbound of material Wi per month, and T represents the total number of outbound times.

[0040] Preferably, the correlation probability calculation formula of the electric power materials is as follows:

[0041]

[0042] Among them, Pij represents the probability that materials Wi and Wj are out of the warehouse together, Cij represents the number of times that materials Wi and Wj are out of the warehouse together, and Cj represents the total number of outbound times of material Wj.

[0043] Preferably, in the dynamic adjustment of the electric power material storage location in step S4, the outbound prediction processing includes a dynamic adjustment step: based on the outbound prediction demand, the materials are adjusted to a position close to the exit.

[0044] Preferably, the buffer area is set in the bottom layer area of the three-dimensional warehouse, and the number of buffer storage locations is reasonably set according to historical outbound orders and emergency outbound orders.

[0045] Compared with the prior art, the beneficial technical effects obtained by the present invention are as follows:

[0046] 1. Improve the outbound efficiency:

[0047] Optimize the storage strategy: By statistically analyzing the outbound frequency of each material, the materials with high outbound frequency are preferentially placed in the storage locations convenient for outbound, and the materials with associated outbound are placed in adjacent areas. The present invention statistically analyzes the outbound frequency of each material through the warehousing control system, combines the usage characteristics of electric power materials, defines the electric power materials that frequently appear in the same outbound task order as related materials, preferentially places the materials with high outbound frequency in the storage locations convenient for outbound, and places the materials with associated outbound in adjacent areas. At the same time, when storing in the warehouse, the related materials are placed adjacent to each other, reducing the number of times of moving the materials, significantly improving the outbound efficiency, and solving the problem of low outbound efficiency caused by unreasonable storage strategies in the prior art.

[0048] Pre-outbound processing: Introduce the pre-outbound method. In the preprocessing stage of the outbound of electric power materials, there is a buffer area inside the warehouse for storing the materials to be received soon. The applicant sends a receiving task order through a remote device, and the WCS control system automatically places the materials in the buffer area. Making preparations for outbound in advance shortens the time of outbound operation, avoids the delay of on-site manual operation, reduces the time of outbound operation after personnel arrive at the warehousing site, improves the outbound efficiency, and makes up for the deficiency of the lack of pre-outbound method in the prior art.

[0049] 2. Dynamically adjust the storage location:

[0050] Adjustment based on seasons and emergencies: The present invention dynamically adjusts material storage locations based on seasonal changes, weather forecasts, project requirements and other factors, and adjusts materials with a high probability of being shipped out in the near future to areas close to exports, ensuring that they can be shipped out quickly during peak demand periods, thereby improving the flexibility and response speed of warehouse management and solving the problem of lack of dynamic adjustment in the prior art.

[0051] Utilize material relevance: By analyzing the outbound relevance of materials, materials with high relevance are placed in physically adjacent areas to facilitate simultaneous outbound delivery, further improving the efficiency of outbound operations.

[0052] 3. Intelligent management:

[0053] Intelligent robot assistance: The present invention equips the three-dimensional storage warehouse with intelligent robots, which automatically collect important information such as weather that can affect the power grid, and generates a delivery forecast based on learning experience. The administrator reviews the delivery forecast and issues a delivery instruction to the WCS system. The WCS system moves the materials from the storage location to the Level II cache area based on the forecast. This reduces the error of human judgment and improves the accuracy and timeliness of delivery forecasts.

[0054] Optimal path selection: The present invention utilizes multi-task parallel intelligent analysis to optimize and schedule tasks. Through the minimum path selection algorithm, it ensures the smooth operation of the conveying equipment, avoids collision with any objects, and maximizes the efficiency of logistics operations.

[0055] 4. Improve the standardization and normalization of warehouse management:

[0056] Information integration: By using information identification technologies such as RFID / barcodes, goods and pallets are bound to data, achieving effective control of the flow status of goods, and reminding applicants through text messages or system messages at the front end of the system that the materials have arrived at the buffer storage location, thus achieving standardization and normalization of warehouse management.

[0057] In summary, the present invention significantly improves the outbound efficiency and management level of three-dimensional warehousing of power materials through a series of technical improvements such as optimizing storage strategies, pre-outbound processing, dynamic adjustment of storage locations, intelligent management and information integration, and solves the problems existing in the prior art such as unreasonable storage strategies, lack of pre-outbound methods, lack of dynamic adjustment, and underutilization of material relevance and seasonal effects, and has broad application prospects.

[0062] The present invention will be further explained below in conjunction with the accompanying drawings and embodiments.

[0063] Reference Figures 1-4 As shown, a method for controlling the rapid outbound storage of electric power materials in a three-dimensional warehouse includes the following steps:

[0064] Step 1: Electric power materials enter the warehouse. The warehouse control system statistically analyzes the frequency of each material’s outbound shipment and the probability of materials that are frequently shipped out in batches based on historical outbound shipments. When entering the warehouse, materials with high outbound shipment frequencies are first placed in cargo locations that are convenient for outbound shipments; secondly, materials that are bound together for outbound shipments are placed in adjacent areas to improve outbound shipment efficiency. The core of this step is to analyze the outbound shipment frequency and material correlation of materials. Based on factors such as the correlation of materials required for work and the correlation of historical outbound shipments, the probability of material correlation is obtained, and materials with high correlation probabilities are placed in physically related areas to facilitate simultaneous outbound shipments. The correlation of each outbound shipment provides a historical basis for the subsequent correlation of materials and provides data samples for model training.

[0065] Step 2: Pre-processing of power materials outbound. A buffer zone is set up inside the warehouse to store materials to be collected. When the user sends a collection task order in advance, the warehouse WCS control system automatically places the materials on the material list into the buffer zone. By using information identification technologies such as RFID / barcodes, the goods and pallets are bound to data to effectively control the flow status of the goods, and the applicant is informed of the arrival of the materials at the buffer zone and can be collected through SMS and system message reminders at the front end of the system. The applicant can also check the outbound status of the goods at any time through the portable device, thus avoiding unnecessary waiting time.

[0066] Step 3: Select the minimum path for power materials to be shipped out of the warehouse. By issuing the outbound task on the remote device terminal, the intelligent analysis of multiple tasks in parallel is used to optimize and schedule the task. The refined splitting of tasks and the analysis of routes are used to ensure the smooth operation of the conveying equipment without collision with any objects. At the same time, it can also maximize the work efficiency and the benefits of logistics operations to meet the higher-level deployment requirements of the WMS system. This method can realize the automatic minimum path selection in the process of material shipment, and intelligently specify the optimal picking location, thereby greatly improving the speed and accuracy of loading and unloading goods.

[0067] Step 4: Dynamic adjustment of the storage locations for power materials. Considering seasonal changes, weather forecasts, project requirements, and the correlation of material requirements, dynamically adjust the storage locations of materials. Move the materials with a high probability of being shipped out in the near future to areas closer to the exit to make emergency preparations, thus enabling fast inbound and outbound operations.

[0068] Method for selecting the inbound storage location of power materials:

[0069] (1) Design of the weight for the convenience of outbound from the three-dimensional storage locations

[0070] The storage locations have attributes such as the number of layers, row positions, and column positions. Based on these attributes, set the weight for the convenience of outbound for each storage location. With the weight attribute for the convenience of outbound of the storage location, when inbounding, calculate the convenience weight of the storage location for placing the material according to the outbound probability and material correlation of the inbound material, and select a suitable storage location.

[0071] The formula for the weight of the convenience of outbound from the storage location is:

[0072] W LRC =W L +W R +W C ;

[0073] Among them, W LRC represents the weight of the convenience of outbound from the storage location (L, R, C), and W L , W R , W C represent the weights of the number of layers, row position, and column position respectively;

[0074] Update the weight of the convenience of outbound from the storage location according to the outbound probability and material correlation of the inbound material:

[0075] W′ LRC =W LRC +(P ij ·weight increment)-((1 - P ij )·weight decrement);

[0076] Among them, Pij represents the correlation probability of the material, and the numbers of the materials are represented by Wi and Wj;

[0077] Referring to the storage diagram of the three-dimensional storage plane shown in Table 1, the weight of the convenience of outbound from each storage location is filled in the storage location grid. A larger weight indicates a more convenient outbound location. In a multi-layer three-dimensional storage, in a similar way, the weight of the convenience of outbound from each storage location on each layer can be designed. In Table 1, there is an aisle in the middle, 5 columns on the left of the aisle, and 5 columns on the right. The weights of the convenience of outbound from the storage locations on both the left and right sides are the same. The storage locations closer to the exit and closer to the aisle have better convenience of outbound and corresponding better weights.

[0078]

[0079] Table 1 Design Table of Weights for Convenience of Warehouse Location Outbound

[0080] For a further preferred solution, in the warehousing of electric power materials, the setting of the weight for the convenience of warehouse location outbound also includes the following steps:

[0081] A. According to the position of the warehouse location close to the exit and the roadway, increase its weight for the convenience of outbound;

[0082] B. In a multi-layer stereoscopic warehouse, design the weights for the convenience of warehouse location outbound for each layer according to the above method.

[0083] Preferably, the calculation formula for the outbound frequency of the electric power materials is:

[0084]

[0085] Among them, Fi represents the outbound frequency of material Wi, Ci represents the number of outbound times of material Wi per month, and T represents the total number of outbound times.

[0086] Preferably, the calculation formula for the correlation probability of the electric power materials is:

[0087]

[0088] Among them, Pij represents the probability that materials Wi and Wj are out of the warehouse together, Cij represents the number of times that materials Wi and Wj are out of the warehouse together, and Cj represents the total number of outbound times of material Wj.

[0089] Example of warehousing of electric power materials:

[0090] Referring to Table 2, assume that there are 6 kinds of electric power materials, namely W1, W2, W3, W4, W5, and W6. According to historical statistics, the outbound frequency of W1 is 18 times per month, the outbound frequency of W2 is 10 times per month, the outbound frequency of W3 is 7 times per month, the outbound frequency of W4 is 2 times per month, the outbound frequency of W5 is 0.5 times per month, and the outbound frequency of W6 is 13 times per month; the probability that W5 and W4 are out of the warehouse together is 100%, the probability that W4 and W3 are out of the warehouse together is 70%, the probability that W3 and W2 are out of the warehouse together is 80%, and the probability that W2 and W1 are out of the warehouse together is 85%. Then, there is a good correlation among the electric power materials W1, W2, W3, W4, and W5. The closest positions when storing these electric power materials are to place W1, W2, W3, W4, and W5 adjacent to each other. Table 2 shows an excellent storage method for these 6 kinds of materials.

[0091] Based on the storage of the six types of materials shown in Table 2, if there are now two types of materials, W7 and W8, to be stored in the warehouse, the outbound frequency of W7 is 10 times per month, and the outbound frequency of W8 is 16 times per month; the probability of W7 and W6 being out of the warehouse together is 90%, and there is no relevant record for W8. For material W7, the weight of the position to the left of W6 for the convenient outbound of W7 can be updated as: 31 + 39×90% - 39×(1 - 90%) = 62.2;

[0092] Therefore, for material W7, the position to the left of W6 is the most suitable position. Material W8 is allocated to the empty position opposite W1 according to the outbound frequency.

[0093] According to the above description, after adding materials W7 and W8, the storage of materials in the warehouse locations is shown in Table 3.

[0094]

[0095] Table 2 is the storage table of materials in the warehouse locations for six types of materials

[0096]

[0097] Table 3 is the storage table of materials in the warehouse locations for eight types of materials

[0098] Embodiment of pre - treatment for outbound of electric power materials

[0099] Refer to Figure 3 As shown, after the WMS system generates a material outbound task order through approval, the WMS system sends the outbound task order to the WCS system. The WCS system generates a pre - treatment work order for outbound according to the minimum path algorithm based on the batch outbound material list. The pre - treatment process for outbound in the three - dimensional warehouse: The WCS receives the material outbound task order sent by the WMS, moves the materials on the task order to the I - level buffer area, and feeds back the information of the completion of pre - treatment to the WMS.

[0100] Refer to Table 4. The buffer area settings for the three - dimensional warehouse locations: Set the I - level buffer area and the II - level buffer area for the three - dimensional warehouse locations. The I - level buffer area is used for pre - treatment of material outbound, and the II - level buffer area is used for the area where materials are temporarily placed according to emergencies such as weather. The buffer area is set in the bottom - most layer area of the three - dimensional warehouse, and the number of buffer warehouse locations is reasonably set according to historical outbound orders and emergency outbound orders.

[0101]

[0102] Table 4 is the schematic table of the I - level and II - level buffer areas

[0103] Embodiment of dynamic adjustment of electric power material warehouse locations

[0104] Refer to Figure 4As shown in the figure, "intelligent robots" are equipped in the three-dimensional storage warehouse for electric power materials to automatically collect important information such as weather that can affect the power grid. Based on past learning experience, the "intelligent robots" give predictions on the outbound of electric power materials, generate outbound prediction forms, and send them to the administrator for review. The administrator reviews according to the outbound prediction form (whether the prediction form is needed, whether the electric power materials on the prediction form are complete, and add or delete the types and quantities of materials according to the situation). The "intelligent robots" receive the approval from the administrator and send the outbound prediction form of electric power materials to the WCS system. According to the outbound prediction form, the WCS system moves the electric power materials in the prediction form from the storage location to the secondary buffer area.
