Description

Technical Field

[0001] The present invention relates to the technical field of warehouse allocation, and in particular, to a method and device for allocating power equipment warehouses. Background Art

[0002] Due to the rapid development of China's economy, people's living standards have also increased significantly, which has led to a significant increase in the demand for industrial and residential electricity. This has put forward new requirements for power projects. The increase in the number of power projects and the increase in project difficulty have resulted in an increasing variety of power materials and larger facilities. This has made the warehousing management of power materials an area that needs attention in current power projects. In order to avoid damage to important power equipment, it is necessary to do a good job in the warehousing management of power materials. In response to the problems existing in the current warehousing management of power materials, reasonable optimization countermeasures should be taken to solve them.

[0003] Power equipment refers to various equipment used for power generation, transmission, transformation, distribution, and consumption. They are an important part of the power system. The quality of power equipment is greatly affected by the storage environment. Due to differences in material composition and internal structure, the optimal storage environment and the storage environment that can be tolerated for different types of power equipment are different. Coupled with the differences in the demand for power equipment between different regions, this makes the selection of warehouses for power equipment a complex process that requires considering multiple factors to ensure the operational efficiency and cost-effectiveness of the warehouse. At present, the management method of power material warehouses in China mainly adopts a hierarchical, graded, and zonal model, resulting in a relatively scattered overall structure of the warehouses. These scattered warehouse layouts are not conducive to the unified scheduling or planning of the warehouses. Summary of the Invention

Obviously, the following drawings are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0049] Figure 2 is the structural schematic diagram of the power equipment warehouse allocation device provided by the embodiment of the present invention. Detailed Embodiments

[0050] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. However, those skilled in the art should clearly understand that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present invention.

[0051] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will be described through specific embodiments in conjunction with the accompanying drawings.

[0052] Figure 1 The implementation flowchart of the power equipment warehouse allocation method provided for the embodiments of the present invention is described in detail as follows:

[0053] Step 101, obtain the storage security requirements of the power equipment to be allocated.

[0054] In this embodiment, the quality of power equipment is greatly affected by the storage environment. The storage security requirements refer to the requirements of power equipment for the storage environment considering equipment safety. Different types of power equipment have different storage security requirements. The following are some of the main influencing factors:

[0055] Temperature: Excessive or too low temperature will affect the performance and lifespan of power equipment. High temperature may cause the internal materials of the equipment to age faster, reduce the insulation performance, and even cause equipment failures. Low temperature may cause the materials to become brittle and affect the mechanical performance of the equipment.

[0056] Humidity: A high-humidity environment will cause corrosion inside the equipment, especially for metal components, affecting the contact performance. A humid environment may also cause the insulation material to absorb moisture, reducing the insulation performance and increasing the risk of electric leakage.

[0057] Dust: Dust and other particles in the air may block the ventilation openings, reduce the heat dissipation efficiency, and cause the equipment to overheat. Dust may also cause electrostatic adsorption on the circuit board, affecting the working stability of electronic components.

[0058] Chemical corrosion: Certain chemical substances, such as chlorides, sulfides, etc., may corrode the equipment shell or internal metal components, affecting the service life of the equipment.

[0059] Electromagnetic interference: Electromagnetic interference in the storage environment may affect the normal operation of power equipment, especially sensitive electronic components.

[0060] Light: Long-term direct sunlight may cause the equipment shell material to age, especially for plastic components. Strong light may also affect light-sensitive components, such as optocouplers, etc.

[0061] Vibration and shock: Vibration and shock in the storage environment may damage the internal structure of the device, causing components to become loose or break.

[0062] Biological factors: Biological factors such as pests and molds may damage the outer shell or internal structure of the device, especially in humid and warm environments.

[0063] Based on the above considerations, specific quantitative analysis can be pre - conducted on the storage safety requirements of various power equipment to determine the acceptable and most suitable range of storage environment parameters.

[0064] Step 102, determine whether the safety indicators of each warehouse meet the storage safety requirements, and regard the warehouses that meet the storage safety requirements as available warehouses.

[0065] In this embodiment, the safety indicators of the warehouse are used to evaluate the safety of power equipment during storage in the warehouse. In this embodiment, the warehouses that meet the storage safety requirements are regarded as available warehouses. Therefore, based on the various requirements in the storage safety requirements, the categories included in the safety indicators can be set one - to - one to determine whether the safety indicators of each warehouse meet the storage safety requirements.

[0066] When the various safety indicators of a certain warehouse all meet the storage safety requirements, it is considered that the warehouse meets the storage safety requirements of the power equipment to be allocated and is suitable for storing the power equipment to be allocated.

[0067] Step 103, calculate the scheduling convenience index of each available warehouse based on the planned storage duration, warehouse address, and the relevance between the stored power equipment and the power equipment to be allocated.

[0068] In this embodiment, scheduling convenience directly affects logistics efficiency, cost, and service level. At present, the management mode of power material warehouses in China mainly adopts a hierarchical, level - by - level, and regional model, resulting in a relatively dispersed overall structure of the warehouses. These dispersed warehouse layouts are not conducive to the unified scheduling or planning of the warehouses. For example, certain types of power equipment usually need to be used, sold, and transported together. If they are stored in different warehouses respectively, the transportation process will be more complex.

[0069] In response to this situation, in this embodiment, through the relevance between the stored power equipment and the power equipment to be allocated, it describes whether there is a need for common sales and transportation between the stored power equipment and the power equipment to be allocated. The greater the relevance, the greater the possibility that there is a need for common sales and transportation between the two. Then storing the two in the same or adjacent warehouses can greatly improve the scheduling convenience.

[0070] In addition, when the planned storage duration is relatively long, the number of scheduling operations for power equipment per unit time is small, and the requirement for scheduling convenience is correspondingly low. Also, the location of the warehouse itself has a certain impact on scheduling convenience. Therefore, in this embodiment, the overall scheduling convenience index of the warehouse is calculated based on the planned storage duration, the warehouse address, and the relevance between the stored power equipment and the power equipment to be allocated.

[0071] Step 104: Select the warehouse with the highest scheduling convenience index among all available warehouses as the warehouse for storing the power equipment to be allocated.

[0072] In this embodiment, the higher the scheduling convenience index of a certain warehouse, the higher the degree of scheduling convenience for storing the power equipment to be allocated in this warehouse, which has a greater optimization effect on the centralized management of power equipment. This warehouse should be preferentially selected for storing power equipment.

[0073] In the embodiment of the present invention, based on the storage safety requirements of power equipment, first, warehouses that can ensure the storage safety of power equipment are screened out from all warehouses. Then, based on the planned storage duration, the warehouse address, and the relevance between the stored power equipment and the power equipment to be allocated, the scheduling convenience index of each available warehouse is calculated. The scheduling convenience degree of storing power equipment in each warehouse is described by the scheduling convenience index, so as to allocate a suitable warehouse for the power equipment, achieve the overall optimal storage state, and complete the transformation of centralized management of equipment, obtaining better warehousing and scheduling effects.

[0074] In a possible implementation manner, the storage safety requirements include one or more of temperature range requirements, humidity range requirements, pollutant concentration requirements, earthquake resistance ability requirements, and anti-theft ability requirements; the safety indicators include temperature control range, humidity control range, pollutant control concentration, earthquake resistance ability index, and anti-theft ability index;

[0075] Judging whether the safety indicators of each warehouse meet the storage safety requirements includes:

[0076] If the temperature control range of the first warehouse includes the temperature range requirement, the humidity control range includes the humidity range requirement, the pollutant control concentration is lower than the pollutant concentration requirement, the earthquake resistance index is higher than the earthquake resistance ability requirement, and the anti-theft ability index is higher than the anti-theft ability requirement, then it is determined that the safety indicators of the first warehouse meet the storage safety requirements; where the first warehouse is any warehouse.

[0077] In this embodiment, too high or too low temperature and humidity will affect the performance and lifespan of power equipment. Therefore, the required temperature and humidity ranges of power equipment should be within the temperature control range and humidity control range of the warehouse respectively to ensure that the quality of power equipment is not damaged during storage.

[0078] Some chemical pollutants such as chlorides and sulfides are corrosive and may corrode the equipment housing or internal metal components. Therefore, for power equipment with pollutant concentrations, it is necessary to judge the warehouse's ability to control pollutant concentrations. When the warehouse's pollutant control concentration is lower than the power equipment's pollutant concentration requirement, the warehouse's storage environment is considered safe for the power equipment.

[0079] Vibrations and shocks in the storage environment may damage the internal structure of the equipment, causing components to loosen or break. Therefore, some power equipment may have requirements for the earthquake resistance of the warehouse. The earthquake resistance of the warehouse can include the ability of the building to remain undamaged during an earthquake, and the ability of the power equipment inside the building to be free from vibrations and shocks during an earthquake. The former can be represented by parameters such as the strength, stiffness, stability, ductility, and energy dissipation capacity of the building, and the latter can be represented by the building's seismic isolation ability.

[0080] The anti-theft ability requirements can be set according to the actual needs of users. The anti-theft ability indicators can be represented by three aspects: physical security, technical security, and management security. Specifically, it can include: Physical security: The degree of perfection of physical protection measures such as fences, gates, locks, alarm systems, surveillance cameras, lighting, and guardrails. Technical security: The advancement and reliability of technologies such as intrusion alarm systems, video surveillance systems, access control systems, and security communication systems. Management security: The implementation of management measures such as security management systems, employee safety training, patrol inspections, and emergency response plans.

[0081] In addition, electromagnetic interference in the storage environment may affect the normal operation of power equipment, and long-term direct sunlight may cause the aging of the equipment housing material of plastic components or affect the performance of light-sensitive components such as optocouplers. Therefore, the safety requirements of power equipment can also include lighting and electromagnetism.

[0082] In a possible implementation, before judging whether the safety indicators of each warehouse meet the storage safety requirements and taking the warehouses that meet the storage safety requirements as available warehouses, it also includes:

[0083] Calculating the pollutant control concentration of each warehouse based on the pollutant control concentration formula, and calculating the anti-theft ability indicator of each warehouse based on the anti-theft ability formula; where the pollutant control concentration formula is:

[0084] C = Lξmτ

[0085] Where C is the pollutant control concentration, L is the distance between the warehouse and the chemical plant, ξ is the pollutant propagation coefficient, m is the pollutant emission mass of the chemical plant, and τ is the transmittance of the warehouse to pollutants;

[0086] The anti-theft ability formula is:

[0087] P i= k1rank[n i , n j + k2rank[n i , m k

[0088] Wherein, P i is the anti-theft ability index of warehouse i, n i is the historical number of thefts of warehouse i, n j is the historical number of thefts of warehouse j, i ≠ j, i, j ∈ [1, I], I is the total number of warehouses, rank[n i , n j is the ranking of the historical number of thefts of warehouse i among all warehouses j, m k is the historical number of thefts of building k in the area where warehouse i is located, rank[n i , m k is the ranking of the historical number of thefts of warehouse i among all buildings k, and k1 and k2 are preset weights.

[0089] In this embodiment, only the pollutant control concentration needs to be calculated for the pollutant categories in the storage security requirements. The emission amounts and the propagation characteristics in the air of different types of pollutants are different. Based on the distance between the warehouse and the chemical plant, the pollutant propagation coefficient, the pollutant emission quality of the chemical plant, and the transmittance of the warehouse to the pollutants, the calculated pollutant control concentration is the upper limit of the possible pollutant concentration inside the warehouse. When the pollutant control concentration is lower than the pollutant concentration requirement of the electrical equipment, it is considered that the pollutants transmitted into the warehouse will not damage the quality of the electrical equipment.

[0090] In the anti-theft ability formula, k1 and k2 can be set according to the actual situation. rank[n i , n j is used to describe the anti-theft ability level of warehouse i among all alternative warehouses. The larger the ranking value, the fewer the historical theft times of warehouse i compared to the historical theft times of other warehouses, that is, the higher the anti-theft ability level. rank[n i , m k is used to describe the anti-theft ability level of warehouse i among all buildings in the same area. The larger the ranking value, the fewer the historical theft times of warehouse i compared to the historical theft times of other buildings, that is, the higher the anti-theft ability level. Therefore, the larger the value of the anti-theft ability index, the stronger the anti-theft ability of warehouse i.

[0091] In a possible implementation manner, it further includes:

[0092] If there is no warehouse that meets the storage security requirements, then based on the difference between the security index of each warehouse and the storage security requirements, calculate the transformation cost of each warehouse; ​

[0093] The calculation formula for the renovation cost is as follows:

[0094] CA = Δ1p1 + Δ2p2 + Δ3p3 + Δ4p4 + Δ5p5

[0095] Where CA is the renovation cost of the warehouse, Δ1 is the difference between the temperature control range of the warehouse and the required temperature range, p1 is the price of the temperature adjustment equipment corresponding to the unit difference, Δ2 is the difference between the humidity control range of the warehouse and the required humidity range, p2 is the price of the humidity adjustment equipment corresponding to the unit difference, Δ3 is the difference between the pollutant control concentration in the warehouse and the required pollutant concentration, p3 is the price of the pollutant barrier equipment corresponding to the unit difference, Δ4 is the difference between the earthquake resistance capacity index of the warehouse and the required earthquake resistance capacity, p4 is the price of the earthquake resistance equipment corresponding to the unit difference, Δ5 is the difference between the anti-theft capacity index of the warehouse and the required anti-theft capacity, and p5 is the price of the anti-theft equipment corresponding to the unit difference;

[0096] Based on the planned storage duration, the warehouse address, and the relevance between the stored power equipment and the power equipment to be allocated, calculate the scheduling convenience index for each warehouse;

[0097] Select the warehouse for storing the power equipment to be allocated among the warehouses based on the renovation cost and the scheduling convenience index.

[0098] In this embodiment, when there is no warehouse that meets the storage safety requirements, the warehouse can be renovated by purchasing the equipment corresponding to the required items to ensure the safety of power equipment storage. Through the calculation formula of the renovation cost, the renovation costs of each warehouse can be quantified, so as to determine a suitable warehouse.

[0099] At the same time, the renovation costs and scheduling convenience indexes of each warehouse can be comprehensively considered, so as to select a warehouse that takes into account both economy and scheduling convenience. For example, set the weights of the renovation cost and the scheduling convenience index, score each warehouse, and select the warehouse.

[0100] In a possible implementation manner, before determining whether the safety indexes of each warehouse meet the storage safety requirements and taking the warehouses that meet the storage safety requirements as available warehouses, it further includes:

[0101] If there are multiple types of power equipment to be allocated, sort the various types of power equipment to be allocated based on the volume, storage safety requirements, and planned storage duration of each type of power equipment to be allocated, and sequentially determine the warehouses for storing each type of power equipment to be allocated according to the order.

[0102] In this embodiment, when there are multiple types of power equipment to be allocated, the storage security requirements of various types of power equipment to be allocated can be compared, and warehouses can be preferentially allocated to the power equipment with relatively strict storage security requirements, so as to avoid placing the allocation order of such power equipment at a later position, resulting in a deterioration of the overall warehouse allocation effect.

[0103] In addition, the larger the volume and the planned storage duration of the power equipment to be allocated, the more the demand for the use of the warehouse in terms of time and space, which should also be considered as a factor in the sorting.

[0104] In a possible implementation manner, sorting various types of power equipment to be allocated based on the volume, storage security requirements, and planned storage duration of various types of power equipment to be allocated includes:

[0105] Calculating the priority allocation index of various types of power equipment to be allocated based on the priority allocation index formula, the volume, storage security requirements, and planned storage duration of various types of power equipment to be allocated; where the priority allocation index formula is:

[0106] d = vt∑rank[x]

[0107] where d is the priority allocation index of the power equipment to be allocated, v is the volume of the power equipment to be allocated, t is the planned storage duration of the power equipment to be allocated, and rank[x] is the ranking of the x-th storage security requirement of the power equipment to be allocated among various types of power equipment to be allocated;

[0108] Sorting various types of power equipment to be allocated in descending order of the priority allocation index.

[0109] In this embodiment, when there are multiple storage security requirements for the power equipment to be allocated, the ranking of each storage security requirement can be determined respectively, and the rankings of each storage security requirement are added together. Among them, the specific way of ranking can be:

[0110] For the temperature range requirement and humidity range requirement, if the range requirement of the power equipment to be allocated A is [a1, a2], and the range requirement of the power equipment to be allocated B is [b1, b2], and a2 - a1 < b2 - b1, then in this ranking, the power equipment to be allocated A is after the power equipment to be allocated B. By comparing the range requirements of various types of power equipment to be allocated through this step, the ranking of the power equipment to be allocated A can be obtained.

[0111] For the pollutant concentration requirement, if the pollutant concentration requirement a3 of the power equipment to be allocated A is less than the pollutant concentration requirement b3 of the power equipment to be allocated B, then in this ranking, the power equipment to be allocated A is after the power equipment to be allocated B.

[0112] The requirements for earthquake resistance and anti-theft capabilities. If the capacity requirement a4 of the power equipment A to be allocated is greater than the capacity requirement b4 of the power equipment B to be allocated, then in this ranking, the power equipment A to be allocated is after the power equipment B to be allocated.

[0113] The larger the volume and planned storage duration of the power equipment to be allocated, the more priority should be given to its warehouse allocation. Therefore, multiplying the volume and planned storage duration by ∑rank[x] can obtain a larger priority allocation index.

[0114] In a possible implementation, based on the planned storage duration, warehouse address, and the relevance between the stored power equipment and the power equipment to be allocated, calculate the scheduling convenience index of each available warehouse, including:

[0115]

[0116] where S i is the scheduling convenience index of warehouse i, t is the planned storage duration, z i is the self-scheduling convenience index corresponding to the warehouse address, L ij is the distance between warehouse i and warehouse j, r ij is the relevance index between the stored power equipment in warehouse j and the power equipment to be allocated.

[0117] In this embodiment, the self-scheduling convenience index corresponding to the warehouse address is a preset value, which can be set according to the distances between the locations of each warehouse and transportation hubs, target markets, and suppliers.

[0118] When the planned storage duration of the power equipment to be allocated is relatively large, it is not necessary to frequently schedule and transport the power equipment, and the requirement for the scheduling convenience index is lower. Therefore, in the formula, the planned storage duration is set to be multiplied by to reduce the requirements for the warehouse address and relevance when the planned storage duration is relatively large.

[0119] The greater the relevance between the stored power equipment and the power equipment to be allocated, the greater the possibility that there are common sales and transportation requirements between the two. Therefore, the distance between the warehouse where the power equipment to be allocated is stored and the warehouse where the associated stored power equipment is stored should be as small as possible. Considering that the power equipment to be allocated and the associated stored power equipment may be stored in the same warehouse, at this time L ij is 0. To avoid the denominator in the formula being 0, the denominator is set to L ih +1.

[0120] In addition, if multiple types of stored power equipment in warehouse j are all relevant to the power equipment to be allocated, then calculate respectively for each type of stored power equipment and sum them up finally.

[0121] In a possible implementation, before calculating the scheduling convenience index of each available warehouse based on the planned storage duration, warehouse address, and the relevance between the stored power equipment and the power equipment to be allocated, it further includes:

[0122] Calculating the relevance between the stored power equipment and the power equipment to be allocated based on the relevance calculation formula; where the relevance calculation formula is:

[0123]

[0124] Where r is the relevance between the stored power equipment and the power equipment to be allocated, SPL is the shortest transmission path length between the stored power equipment and the power equipment to be allocated in the power supply chain network, SRI is the supply risk index between the stored power equipment and the power equipment to be allocated, DE is the demand elasticity between the stored power equipment and the power equipment to be allocated, and SC is the synergy effect coefficient between the stored power equipment and the power equipment to be allocated.

[0125] In this embodiment, in the power supply chain network, the shortest path length SPL can measure the shortest transmission path from equipment A to equipment B. By calculating the shortest path length L from A to B, a value can be obtained. The smaller this value is, the closer the direct connection between A and B. If L = 1, it means A and B are directly connected; if L > 1, it means there are intermediate devices.

[0126] Regarding the supply risk index, if considering equipment A and B, where A is the upstream equipment of B, by calculating the supply risk index SRI, the impact degree of A's supply interruption on B and the entire supply chain can be evaluated. If the value of SRI is very high, it indicates that B has a high dependence on A, and A's supply risk will have a significant impact on B.

[0127] Regarding the demand elasticity, assume that equipment A is a power generation equipment and B is a power consumption equipment. The demand elasticity E can be used to measure the sensitivity of B's demand quantity to A's output quantity. If the value of E is very large, it indicates that the change in A's output quantity will cause a significant change in B's demand quantity, indicating a strong relevance between the two.

[0128] Regarding the synergy effect coefficient, if equipment A and B are often sold together, their synergy effect coefficient SY can be calculated to measure whether the quantity sold together is better than the sum of the quantities sold separately. If SY > 1, it indicates that a positive synergy effect is generated when A and B are sold together, and their relevance is relatively strong.

[0129] The above indicators can evaluate the degree of relevance between two types of power equipment from multiple aspects. By taking the average value, the integration of the above indicators can be achieved.
