It aims to automate, refine, and intelligentize warehouse operations. Through real-time data collection and analysis, the system optimizes core processes such as inventory management, storage, order picking, and logistics distribution, significantly improving warehouse efficiency and reducing operating costs.
[0003] The intelligent warehouse management system can help the storage park to check costs before providing warehousing services to customers, thereby ensuring feasible profits. However, the existing technology usually only considers easily quantifiable fixed costs and variable costs when conducting cost checks, but lacks a quantitative calculation process for implicit costs, such as equipment depreciation and road maintenance, resulting in inaccurate cost checks and certain defects. Summary of the Invention
[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides an intelligent warehouse management system and method, which can effectively solve the problem of lack of quantitative calculation of hidden costs in the cost verification process of the prior art.
[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions:
[0006] The present invention provides an intelligent warehouse management system, which at least includes:
[0007] The demand calculation unit records the goods to be stored as warehouse goods, divides the warehouse goods into multiple target goods of different weights and volumes, calculates the required number of shelves corresponding to the warehouse goods, and calculates the number of single-type pallets corresponding to the target goods;
[0008] Calculate the required number of forklifts for the target goods based on the number of single-type pallets, the single stacking efficiency of the target goods, and the preset stacking time threshold.

[0012] Construct a conditional set consisting of multiple idle warehouses. The idle warehouses in the conditional set meet the cost constraint formula. The cost constraint formula is influenced by factors including the estimated total rent, warehouse depreciation cost, road depreciation cost, and single-day usage cost. The road depreciation cost is calculated based on the transportation frequency impact value of the warehoused goods, the road impact value, and the shortest path corresponding to the idle warehouse.
[0013] The decision generation unit generates different signals based on the number of condition sets that are met.
[0014] Furthermore, the shelf demand quantity calculation process is as follows:
[0015] Each type of warehouse goods is recorded as the target goods, and the corresponding goods quantity, goods weight, and goods size are obtained. Combined with the volume capacity limit and weight capacity limit of a single-layer shelf, the upper limit of the number of target goods that a single-layer shelf can accommodate is calculated and recorded as the single-layer upper limit and the corresponding shelf demand quantity for the warehouse goods.
[0016] Furthermore, the calculation process for the number of pallets of a single type is as follows:
[0017] Obtain the quantity, weight, and size of the target goods, as well as the upper volume and weight capacity limits of the forklift pallet. Analyze and calculate the upper limit on the number of target goods that each forklift pallet can accommodate, which is recorded as the single pallet upper limit and the number of single-type pallets corresponding to the target goods.
[0018] Furthermore, the calculation process of the required number of forklifts is as follows:
[0019] Obtain the single stacking efficiency corresponding to the target product, obtain the preset stacking time threshold, divide the number of single-type pallets by the product of the stacking time threshold and the single stacking efficiency, and take the smallest integer not less than the calculated result to obtain the required number of forklifts corresponding to the target product.
[0020] Furthermore, the calculation process of the single stacking efficiency corresponding to the target product is as follows:
[0021] Get the target product THING i Corresponding single support upper limit Num″ i , get the product size v corresponding to the target product i , through the formula Calculate the center of gravity reference value β1 and obtain the weight m of the target product i , where S represents the maximum placement area of the forklift pallet;
[0022] By formula The load reference value β2 is calculated, where M is the rated load weight of the forklift and k is the preset load influence coefficient;
[0023] A fragile reference value is preset, and the fragile reference value is assigned based on whether the target product is fragile. When the target product is fragile, the fragile reference value is assigned to 1, and when the target product is not fragile, the fragile reference value is assigned to 0;
[0024] Obtain the target product's center of gravity reference value, load reference value, and fragility reference value, and substitute them into the formula Calculate in and get the single stacking efficiency Among them, λ1, λ2, and λ3 are all preset weight coefficients, and time0 is the preset single basic duration.
[0025] Furthermore, the calculation process of warehouse depreciation cost is as follows:
[0026] Get the depreciation assessment value ZJ corresponding to each idle forklift in the idle forklift set i,f , substitute into the first depreciation cost formula to calculate and obtain the forklift depreciation cost α1 corresponding to all target goods. The first depreciation cost formula is Where η1 is the preset forklift depreciation coefficient, β 2,i It represents the weight reference value corresponding to the target product, and T is the stacking time threshold.
[0027] Get the quantity Num of the target product i , Single layer upper limit Num′ i 、Goods weight m i , substitute into the second depreciation cost formula to calculate and obtain the shelf depreciation cost α2 corresponding to all target goods. The second depreciation cost formula is Where η2 is the preset shelf depreciation coefficient.
[0028] Calculate the sum of shelf depreciation cost and forklift depreciation cost to obtain the storage depreciation cost of the stored goods.
[0029] Furthermore, the depreciation valuation calculation process of idle forklifts is as follows:
[0030] Obtain the number of times the idle forklift has been used, the years it has been used, and the total weight of the transported goods. After normalization, multiply them by the corresponding weight coefficients and sum them to obtain the depreciation assessment value.
[0031] Furthermore, the cost limiting formula is specifically:
[0032] in:
[0033] LR′ is the profit threshold of a single position, ε1 and ε2 are the preset weight coefficients, and ZJ all represents the total estimated rent, CB1 represents the storage depreciation cost, CB2 represents the road depreciation cost, CB3 represents the cost of single-day use, T allrepresents the number of rental days, and p+1 represents the total number of warehouse requirements.
[0034] Furthermore, the pavement depreciation cost calculation process is as follows:
[0035] Divide the shelf demand quantity by the number of warehouse shelf units to obtain the warehouse demand value, and divide the warehouse demand value into an integer part and a decimal part q, where the integer part is equal to p;
[0036] Based on the navigation software, the shortest path between the idle warehouse and the nearest storage park exit is obtained, and the shortest paths are recorded as lines in ascending order. n , where n is the serial number of the idle warehouse;
[0037] Divide the number of freight shipments by the storage time to get the transport frequency impact value;
[0038] Calculate the sum of the freight weight and the vehicle weight to get the total impact weight value, and divide the total impact weight value by the number of axles of the truck to get the road impact value;
[0039] Suppose the shortest path set corresponding to the condition satisfying set is {line′ m}, the road impact value and transportation frequency impact value corresponding to the warehouse goods are recorded as m all , time′, and substitute it into the third cost formula to calculate the pavement depreciation cost;
[0040] The third cost formula is as follows:
[0041]
[0042] An intelligent warehouse management method comprises the following steps:
[0043] Step 1: Record the single transport weight of the stored goods as the freight weight, calculate the total weight of the stored goods and divide it by the freight weight to get the number of freight shipments. Obtain the storage time of the stored goods and divide the number of freight shipments by the storage time to get the transportation frequency impact value.
[0044] Step 2: Denote the truck transporting the stored goods as the target truck, obtain the curb weight of the target truck as the vehicle weight, calculate the sum of the cargo weight and the vehicle weight to obtain the total impact weight value, obtain the number of axles of the target truck as the target axle number, and divide the total impact weight value by the target axle number to obtain the road impact value;
[0045] Step 3: Using navigation software, obtain the route between the idle warehouse and the nearest storage park exit as the shortest route. Calculate the length of the shortest route corresponding to each idle warehouse as the shortest path.
[0046] Step 4: Divide the number of shelf requirements by the number of warehouse shelf units to obtain the warehouse demand value. The warehouse demand value is divided into an integer part p and a decimal part q. P+1 idle warehouses are extracted to form a condition-satisfied set. The idle warehouses in the condition-satisfied set meet the cost limitation formula. The road depreciation cost in the cost limitation formula is calculated based on the transportation frequency impact value of the warehoused goods, the road impact value, and the shortest path corresponding to the idle warehouse.
[0047] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:
[0048] 1. The present invention can conduct a multi-angle assessment of the goods that customers need to store before the storage park provides warehousing services to customers, especially predicting and calculating the hidden costs generated during the warehousing service process, such as the depreciation costs of forklifts and shelf equipment, and the depreciation costs of road damage. Based on the cost verification of existing technologies, the warehouse rental profit can be calculated more accurately, and a more preferred idle warehouse rental combination can be provided for the warehousing park, so as to control the hidden costs paid during the warehousing service process as much as possible.
[0049] 2.

BRIEF DESCRIPTION OF THE DRAWINGS
[0050] To more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments of the present invention. Those skilled in the art can also derive other drawings based on these drawings without inventive effort.
[0051] Figure 1 It is the overall module block diagram of the present invention. DETAILED DESCRIPTION
[0052] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.
[0053] The present invention will be further described below with reference to the embodiments.
[0054] See Figure 1 An intelligent warehouse management system is suitable for a warehouse park with multiple warehouses distributed within it for zoned storage. The warehouse park is leased to provide warehousing services to different customers, including at least:
[0055] The demand calculation unit records the goods that customers need to store as warehousing goods and analyzes the equipment loss cost when providing warehousing services based on the customer's warehousing goods data, including:
[0056] Get the type and quantity of the warehouse goods as j, and record each type of warehouse goods as the target goods THING i , get the quantity of different types of target goods and record it as the quantity of goods Num i , each product quantity corresponds to a product weight m i and a product size (product volume) v i , get the upper limit of the volume of a single shelf and weight capacity Substitute into the formula Calculate the required number of shelves Num all ,in:
[0057] Indicates that the value is not less than The smallest integer;
[0058] Indicates taking The minimum value in ;
[0059] Num i ' indicates that a single shelf can accommodate the target product THING i The upper limit of quantity is recorded as the single-layer upper limit;
[0060] It should be noted that the number of types refers to the variety of goods of different specifications included in the warehouse goods. Goods of different weights or sizes are recorded as a separate category. For example, if the warehouse goods include three sizes of goods, and one size has two weights, the number of types is 4. By calculating the required number of shelves, we can determine the number of shelves required to accommodate all warehouse goods. This is used to determine the number of warehouses required for the storage of warehouse goods. This result is calculated based on the upper limit of the shelf capacity requirements and is more consistent with the actual storage conditions of warehouse goods.
[0061] Specifically, the required number of shelves is divided by the number of warehouse shelf units (i.e., the number of shelves set up in each warehouse) and the smallest integer not less than the calculated result is taken to obtain the required number of warehouses, which represents the number of warehouses required to store the warehoused goods.
[0062] Get the upper limit of the forklift pallet volume and weight capacity Substitute into the formula Calculate and get the target product THING i Corresponding number of single type pallets in:
[0063] Indicates that the value is not less than The smallest integer;
[0064] Indicates taking The minimum value in ;
[0065] Num″ i Indicates the target item THING that each forklift pallet can accommodate i The upper limit of quantity is recorded as the upper limit of single pallet;
[0066] It should be noted that the goods stacking process in the warehouse management process is usually completed by a forklift. The target goods are placed on the pallet, and then the pallet is lifted and moved by the forklift to stack the target goods on the shelves in the warehouse.
[0067] Depreciation assessment unit, obtain the target product THING i Corresponding single stacking efficiency (Forklift loading target goods THING within unit time i The number of pallets), get the preset stacking time threshold T (set by the staff according to the customer's stacking requirements during implementation), and substitute it into the formula Calculate and get the target product THING i The corresponding number of forklifts required in Indicates that the value is not less than The smallest integer.
[0068] More specific, target product THING i Corresponding single stacking efficiency The calculation process is as follows:
[0069] Get the target product THING i Corresponding single support upper limit Num″ i , get the product size v corresponding to the target product THINGi i , through the formula Calculate the center of gravity reference value β1 and obtain the target product THING i The corresponding product weight m i , where S represents the maximum placement area of the forklift pallet (i.e., the maximum placement area of the bottom layer of goods during the placement process within the pallet's carrying capacity);
[0070] By formula Calculate a load reference value β2, where M is the rated load weight of the forklift and k is a preset load influence coefficient (in a specific embodiment, the value is 0.05);
[0071] It should be noted that in order to ensure the stability of the goods when the forklift is moving, it is usually necessary to place the goods as low as possible to lower the center of gravity of the goods. Therefore, the center of gravity reference value reflects the height of the center of gravity of the goods when the forklift is transporting and stacking the target goods. Generally speaking, the higher the center of gravity, the greater the restriction on the forklift's moving speed, and the lower the forklift's transportation and stacking efficiency; and heavier goods may require a slower handling speed, or more frequent rest times to prevent the forklift from overheating or the battery from consuming too quickly. Therefore, the load reference value also affects the forklift's transportation and stacking efficiency.
[0072] A fragile reference value is preset, and the fragile reference value is assigned based on whether the target product is fragile. When the target product is fragile, the fragile reference value is assigned to 1; otherwise, when the target product is not fragile, the fragile reference value is assigned to 0;
[0073] It should be noted that whether the target goods are fragile can be determined by whether there is a fragile mark on the packaging of the goods.
[0074] Obtain the target product's center of gravity reference value, load reference value, and fragility reference value, and substitute them into the formula Calculate in and get the single stacking efficiency λ1, λ2, and λ3 are all preset weight coefficients, and time0 is a preset single basic duration (in a specific embodiment, the value is 10 minutes).
[0075] It should be noted that the single stacking efficiency is affected by the data of the goods themselves. The single stacking efficiency calculated based on the center of gravity reference value, load reference value and fragility reference value can specifically evaluate the stacking efficiency of forklifts when stacking different types of goods, which is conducive to more accurate calculation of the number of forklifts required for the warehouse goods stacking process.
[0076] The number of forklifts required for the target goods is sorted in ascending order according to the weight reference value of the target goods. The idle forklifts in the storage park (i.e., forklifts that are not assigned to stacking tasks) are recorded as idle forklifts. The idle forklifts are sorted in ascending order according to the depreciation assessment value of the idle forklifts. Based on the serial number of the idle forklifts, they are assigned to the stacking tasks of different target goods. The idle forklifts with smaller serial numbers correspond to the larger weight reference value of the target goods. The idle forklift set corresponding to the target goods is obtained {FT i,f}, f represents the serial number corresponding to the idle forklift;
[0077] It should be noted that assigning tasks to idle forklifts according to characteristic rules can balance the impact of further depreciation of idle forklifts with different ages during the stacking task process, so that the aging of old idle forklifts can be reduced as much as possible, the service life of idle forklifts can be increased, and the occurrence of failures caused by forklift aging can be reduced.
[0078] Get the required number of forklifts for the target goods Get the depreciation assessment value ZJ corresponding to each idle forklift in the idle forklift set i,f , substitute into the first depreciation cost formula to calculate and obtain the forklift depreciation cost α1 corresponding to all target goods. The first depreciation cost formula is Where η1 is the preset forklift depreciation coefficient (set by the staff during implementation), β 2,i Indicates the target product THING i The corresponding load reference value.
[0079] Specifically, the depreciation valuation calculation process of idle forklifts is as follows:
[0080] Obtain the number of times an idle forklift is used, the years it has been used, and the total weight of the transported goods, and record them as the number of times used FT after normalization. a , Used Years FT b and total weight of transported goods FT c , substitute into the formula ZJ=μ1*FT a +μ2*FT b +μ3*FT c Calculation is performed to obtain the depreciation assessment value ZJ, where μ1, μ2, and μ3 are all preset weight coefficients.
[0081] It should be noted that the unit usage of a forklift refers to a complete stacking process, that is, from lifting the goods to putting down the goods is counted as one usage. The weight of the goods lifted by the forklift each time can be recorded by the driving system installed on the forklift. By calculating the depreciation assessment value, the aging degree of idle forklifts can be quantitatively assessed.
[0082] Obtain the number of single-type pallets and the upper limit of single layer corresponding to the target goods, substitute them into the second depreciation cost formula for calculation, and obtain the shelf depreciation cost α2 corresponding to all target goods. The second depreciation cost formula is Where η2 is the preset shelf depreciation coefficient (set by the staff during implementation).
[0083] Calculate the sum of shelf depreciation cost and forklift depreciation cost to obtain the storage depreciation cost of the stored goods.
[0084] It should be noted that the use of forklifts and shelves is indispensable in the warehousing process of goods, and it is difficult to quantify the impact of different types of goods on the depreciation of warehousing equipment in existing technologies. By calculating the warehousing depreciation cost, it can be reflected that the degree of depreciation of forklifts and shelves caused by the storage process when the goods are stored, thereby quantitatively evaluating the depreciation cost corresponding to the stored goods, helping decision makers decide whether it is worthwhile to provide warehousing services for the stored goods, and facilitating cost verification in the warehousing management process.
[0085] The collective optimization unit analyzes the cost of the impact of storage goods transportation on the storage park based on the single transportation weight of the storage goods, including:
[0086] The single transport weight of the stored goods is recorded as the freight weight. The total weight of the stored goods is calculated and divided by the freight weight to obtain the number of freight trips. The storage time of the stored goods is obtained, and the number of freight trips is divided by the storage time to obtain the transportation frequency impact value.
[0087] It should be noted that the single transport weight refers to the single weight of the target goods transported by truck during the process of outbound and inbound transportation, which is usually equal to the rated load of the logistics truck used by the customer. In order to determine the efficiency of inbound and outbound transportation, customers usually use trucks to transport the target goods when the trucks are fully loaded.
[0088] The target truck is designated as the target truck. The curb weight (i.e., vehicle weight) of the target truck is obtained and recorded as the vehicle weight. The total impact weight is calculated as the sum of the cargo weight and the vehicle weight. The total impact weight reflects the ground pressure exerted by the target truck when fully loaded with cargo. The number of axles of the target truck is obtained and recorded as the target axle number. The road impact value is obtained by dividing the total impact weight by the target axle number.
[0089] The warehouses in the storage park are divided into idle warehouses and warehouses in use. The total rent of the warehouses in use is obtained. The single-day usage cost is preset (set by the staff during the specific implementation process). The single-day usage cost is multiplied by the number of rental days to get the total cost. The total cost is divided by the total rent to calculate the profit ratio corresponding to the warehouses in use. The average of the profit ratios corresponding to all warehouses in use is calculated to get the average profit LR1. The park profit threshold LR0 is preset and substituted into the formula Calculate the single position profit threshold LR′, where Z all It represents the total number of warehouses in the storage park, and Z1 represents the total number of warehouses in use;
[0090] It should be noted that the total rental amount of an idle warehouse includes all rental fees paid by the customer (including but not limited to charges for venue, equipment, management, etc.). The cost of using a single day includes all fixed costs of the warehouse in use (including but not limited to land / property depreciation, property maintenance, and management staff salaries). The profit threshold for a single warehouse is used to limit the minimum profit for renting out an idle warehouse, thereby ensuring that the overall profit of the park is not lower than the preset threshold.
[0091] Based on the navigation software, the route between the idle warehouse and the nearest storage park exit is recorded as the shortest route. The length of the shortest route corresponding to each idle warehouse is calculated and recorded as the shortest path. The shortest paths of each idle warehouse are recorded in order from the smallest to the largest shortest paths as line n , where n is the serial number of the idle warehouse;
[0092] Divide the number of shelf requirements by the number of warehouse shelf units to obtain the warehouse demand value, divide the warehouse demand value into an integer part p and a decimal part q, and extract p+1 idle warehouses to form a set that meets the conditions;
[0093] The condition-satisfying set corresponds to multiple idle warehouses, and the idle warehouses in the condition-satisfying set meet the cost limit formula in:
[0094] ε1 and ε2 are preset weight coefficients;
[0095] ZJ all Indicates the estimated total amount of rent;
[0096] CB1 represents the storage depreciation cost;
[0097] CB2 represents the pavement depreciation cost, which is calculated based on the shortest path set corresponding to the condition satisfaction set;
[0098] CB3 represents the cost of use per day;
[0099] T all Indicates the number of days of rental;
[0100] It should be noted that by screening, multiple condition satisfaction sets that meet the cost limitation formula are obtained, so as to determine the idle warehouses that meet the cost requirements. One or more idle warehouses corresponding to the condition satisfaction set can form an adaptive idle warehouse selection set as much as possible under the premise of meeting the minimum profit requirements of the warehousing park, thereby helping to select the idle warehouse selection set with the lowest implicit cost.
[0101] Specifically, the process of calculating the pavement depreciation cost is as follows:
[0102] Suppose the shortest path set corresponding to the condition satisfying set is {line′ m}, the road impact value and transportation frequency impact value corresponding to the warehouse goods are recorded as m all , time′, and substitute it into the third cost formula to calculate the pavement depreciation cost;
[0103] The third cost formula is as follows:
[0104]
[0105] It should be noted that the pavement depreciation cost reflects the impact of transporting stored goods on the depreciation of roads within the park. This value is affected by the pavement impact value corresponding to the stored goods (i.e., the pressure on the road surface caused by each transportation) and the transportation frequency impact value (the number of transportations). Generally speaking, large trucks that frequently transport goods will cause excessive wear and tear on the roads within the storage park, thereby increasing pavement maintenance costs. Therefore, the greater the pavement impact value and transportation frequency impact value, the greater the pavement depreciation cost. By calculating the pavement depreciation cost, it can help staff quantify the pavement depreciation caused by the transportation of stored goods, thereby more accurately conducting cost verification.
[0106] The decision-making unit generates a warehousing profit anomaly signal when a set of conditions cannot be formed to remind staff that providing warehousing services for the goods may result in excessively high hidden costs and the goods are not suitable for service.
[0107] When there is a condition satisfying set, the condition satisfying set is recorded as the target satisfying set, and multiple idle warehouses corresponding to the condition satisfying set are provided to the customer to provide warehousing services for the customer;
[0108] When there are multiple condition satisfaction sets, the sum of the corresponding shortest path subscripts in each condition satisfaction set is calculated to obtain the priority evaluation value, and the condition satisfaction set with the largest priority evaluation value is selected as the target satisfaction set. Multiple idle warehouses corresponding to the target satisfaction set are provided to customers to provide them with warehousing services.
[0109] An intelligent warehouse management method comprises the following steps:
[0110] Step 1: Record the single transport weight of the stored goods as the freight weight, calculate the total weight of the stored goods and divide it by the freight weight to get the number of freight shipments. Obtain the storage time of the stored goods and divide the number of freight shipments by the storage time to get the transportation frequency impact value.
[0111] Step 2: Denote the truck transporting the stored goods as the target truck, obtain the curb weight of the target truck as the vehicle weight, calculate the sum of the cargo weight and the vehicle weight to obtain the total impact weight value, obtain the number of axles of the target truck as the target axle number, and divide the total impact weight value by the target axle number to obtain the road impact value;
[0112] Step 3: Using navigation software, obtain the route between the idle warehouse and the nearest storage park exit as the shortest route. Calculate the length of the shortest route corresponding to each idle warehouse as the shortest path.
[0113] Step 4: Divide the number of shelf requirements by the number of warehouse shelf units to obtain the warehouse demand value. The warehouse demand value is divided into an integer part p and a decimal part q. P+1 idle warehouses are extracted to form a condition-satisfied set. The idle warehouses in the condition-satisfied set meet the cost limitation formula. The road depreciation cost in the cost limitation formula is calculated based on the transportation frequency impact value of the warehoused goods, the road impact value, and the shortest path corresponding to the idle warehouse.
[0114] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
