Description

Technical Field

[0001] The present application relates to the field of supply chain management and industrial Internet technology, and in particular to a material distribution method, device and electronic equipment. Background Art

[0002] Some companies are made up of multiple factories or organizations, which are scattered across the country or even the world. In some scenarios, such as centralized procurement by multiple organizations and allocation of shared resources, the supply chain management department allocates materials based on the material requirements submitted by each factory or organization. Currently, this mainly relies on manual adjustments, which have problems in terms of efficiency and accuracy.

[0003] When the supply of materials is less than the demand, each factory or organization, out of fear of resource shortage and in preparation for the long term, will increase their respective demand reports in order to obtain as much allocation as possible, resulting in unbalanced material distribution.

[0004] From the perspective of supply chain management, some materials have a procurement cycle, which may be as short as 3-5 days or as long as 2-3 months. During the procurement cycle, the demand for a certain material at the factory or organization end may fluctuate. As the actual demand of each organization fluctuates, some organizations may have stagnant materials and others may be short of materials, exacerbating the imbalance of material distribution. In the case of a large supply chain span or a long material lead time, the contradictions and conflicts of uneven material distribution will be further magnified.

[0005] In view of the above situation, if the secondary transfer method is used to solve the problem of uneven material distribution, it will bring great burden to the overall logistics cost and management cost. The existing technology mainly distributes materials based on data from previous years or human experience, and is coordinated by offline material controllers. This is not applicable in the context of the rapid changes in current market demand. Summary of the invention

[0006] In view of this, the purpose of this application is to propose a material allocation method, device, equipment and storage medium to make the material distribution among multiple demand parties more scientific and reasonable.

[0008] The second aspect of the present application provides a material allocation device, including: an allocation ratio calculation module, which is used to calculate the material allocation ratio of the current time unit according to the material procurement lead time and historical forecast data when the total material supply of the current time unit is less than the total material demand of the current time unit, and obtain first material allocation ratio information; wherein the historical forecast data includes multiple historical time units and their corresponding material demand forecast information; the material demand forecast information includes the material demand forecast value of each demander corresponding to each time point in the current time unit, and the material demand forecast value is predicted in the historical time unit; an allocation result calculation module, which is used to allocate materials according to the material supply information, the material demand information and the first material allocation ratio information, and obtain a material allocation result; wherein the material supply information includes the material supply quantity corresponding to each time point in the current time unit, the material demand information includes the material demand of each demander corresponding to each time point in the current time unit, and the material allocation result is used to indicate the material quantity allocated to each demander at each time point in the current time unit.

[0009] The third aspect of the present application provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the program, the material distribution method as described in the first aspect of the present application is implemented.

[0010] A fourth aspect of the present application provides a non-transitory computer-readable storage medium, wherein the non-transitory computer-readable storage medium stores computer instructions, and the computer instructions are used to enable a computer to execute the material distribution method as described in the first aspect of the present application.

[0011] From the above, it can be seen that the technical solutions of the material allocation method, device, equipment and storage medium provided by the present application at least bring the following beneficial effects: The present application introduces historical forecast data to conduct a more comprehensive dynamic data set analysis, making the material preparation management and actual material distribution more scientific and reasonable. At the same time, the automatic calculation of the material allocation results is realized through the system model to avoid the errors caused by human calculations, while also reducing the dependence on personnel and alleviating the management burden of the enterprise. In this way, the problem of limited material allocation among multiple demand parties is solved to a certain extent, so that resources can be more reasonably allocated and more efficiently used in the scenario of material shortage.

[0029] Please refer to Figure 1 , which shows a schematic diagram of an application program running environment provided by an embodiment of the present application. The application program running environment may include: a terminal device 10 and a server 20.

[0030] The terminal device 10 includes, but is not limited to, user equipment (UE), mobile devices, user terminals, terminals, cellular phones, cordless phones, personal digital assistants (PDAs), handheld devices, computing devices, vehicle-mounted devices, mobile phones, computers, intelligent voice interaction devices, smart home appliances, game consoles, e-book readers, multimedia playback devices, wearable devices, and other electronic devices. The client of the application program can be installed in the terminal 10.

[0031] The server 20 is used to provide background services for the client of the application in the terminal device 10. For example, the server 20 can be the background server of the above application. The server 20 can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms.

[0033] Please refer to Figure 2 , which shows a flow chart of a material allocation method provided by an embodiment of the present application. The method can be applied to a computer device and executed by the computer device. The above-mentioned computer device refers to an electronic device with data calculation and processing capabilities, and the above-mentioned computer device includes but is not limited to a terminal, a server or other processing equipment. Optionally, the execution subject of each step in the above-mentioned material allocation method can be Figure 1 The terminal device 10 or server 20 in the application running environment shown. In some possible implementations, the material allocation method can be implemented by a processor calling a computer-readable instruction stored in a memory. The method can include the following steps (S210-S220).

[0034] S210: When the total material supply of the current time unit is less than the total material demand of the current time unit, the material allocation ratio of the current time unit is calculated according to the material procurement lead time and historical forecast data to obtain first material allocation ratio information.

[0035] The related art provides some stock preparation solutions based on the situation in previous years, but the market changes are very dynamic, and it is impossible to get a scientific and reasonable stock preparation solution based on the situation in previous years. The solution of the embodiment of the present application introduces historical forecast data, and through a more comprehensive dynamic data set analysis, the stock preparation management and actual material distribution are more scientific and reasonable.

[0036] Among them, the historical forecast data includes multiple historical time units and their corresponding material demand forecast information. The material demand forecast information includes the material demand forecast value of each demander corresponding to each time point in the current time unit. The material demand forecast value is predicted within the historical time unit.

[0037] Among them, the material demand forecast values ​​of each demander corresponding to different time points in the historical time unit are independent of each other and completely unrelated.

[0038] The time unit is the minimum time period for material allocation, and there are multiple time points in one time unit. Specifically, for example, the time unit in this embodiment is a week. For another example, in other embodiments, the time unit can also be a ten-day period, a month, etc., which is not limited here. Since the lead time and procurement cycle of materials may be relatively long, first determine the materials allocated to each time unit, and then allocate the materials in the time unit to each time point, which can make the material allocation between the various demand parties more reasonable and effective to a certain extent.

[0039] Figure 3 is a flow chart of calculating the first material allocation ratio information in an embodiment of the present application, such as Figure 3 As shown, in some embodiments, calculating the material allocation ratio of the current time unit according to the material procurement lead time and historical forecast data to obtain the first material allocation ratio information may include the following steps:

[0040] S211: Determine the target historical time unit corresponding to the current time unit according to the material procurement lead time and the first preset rule.

[0041] In some embodiments, step S211 may include the following steps: calculating the lead time according to the procurement lead time and the first preset rule to obtain a plurality of different lead times, and determining a plurality of target time units according to the current time unit and the plurality of different lead times.

[0042] In this embodiment, the first preset rule is used to represent the correspondence between the procurement lead time and the lead time, and the multiple lead times include an lead time equal to the procurement lead time, at least one lead time less than the procurement lead time, and at least one lead time greater than the procurement lead time.

[0043] Specifically, for example, three lead times are determined according to the procurement lead time and the first preset rule, and the first lead time is , the second advance time is and the third advance time is ,in, It is the abbreviation of material procurement lead time. Based on the above three lead times, the emergency material preparation period, standard material preparation period and strategic material preparation period corresponding to the current time unit can be determined. The emergency material preparation period is a historical time unit obtained by tracing back the first lead time from the current time unit, the standard material preparation period is a historical time unit obtained by tracing back the second lead time from the current time unit, and the strategic material preparation period is a historical time unit obtained by tracing back the third lead time from the current time unit.

[0044] S212: Filtering out target prediction information from the historical prediction data according to the target historical time unit.

[0045] The target forecast information is the material demand forecast information corresponding to the target historical time unit, for example, the material demand forecast information for the emergency material preparation period, the material demand forecast information for the standard material preparation period, and the material demand forecast information for the strategic material preparation period.

[0046] S213: Perform weighted calculation on the material demand quantity forecast value of each demander based on the weight of the target historical time unit and the target forecast information to obtain the material demand quantity evaluation value of each demander.

[0047] As mentioned above, in this embodiment, the weight order of multiple target historical time units is standard preparation period > strategic preparation period > emergency preparation period. Specifically, for example, the weight of the strategic preparation period is 30%, the weight of the standard preparation period is 60%, and the weight of the emergency preparation period is 10%. The material demand assessment value of a demander = the predicted value of the material demand of the demander in the strategic preparation period * 30% + the predicted value of the material demand of the demander in the standard preparation period * 60% + the material demand of the demander in the emergency preparation period * 10%. In other embodiments, the specific values ​​of the weights of multiple target historical time units and the order of the weights can also be set according to actual conditions, and there is no limitation on this.

[0048] S214: Calculate the ratio of the material demand evaluation value of each demander to the sum of the material demand evaluation values ​​of each demander to obtain first material allocation ratio information.

[0049] The first material allocation ratio information includes the material allocation ratio of each demander corresponding to the current time unit.

[0050] S220: Perform material allocation according to the material supply information, the material demand information and the first material allocation ratio information to obtain a material allocation result.

[0051] The material allocation result is used to indicate the quantity of materials allocated to each demander at each time point in the current time unit.

[0052] The material supply information includes the material supply quantity corresponding to each time point in the current time unit. The total material supply is the sum of the material supply quantities corresponding to the current time unit. The total material supply can be directly obtained or calculated based on the material supply information. Specifically, the material supply information includes at least one of the supplier's commitment, the inventory in the warehouse, and the inventory in transit. For example, when receiving materials, the material supply information takes the supplier's promised deliverable quantity. When transferring, the material supply information is the existing inventory and the in-transit shipping order.

[0053] Among them, the material demand information includes the material demand of each demander corresponding to each time point in the current time unit. The total material demand is the sum of the material demand corresponding to the current time unit. The total material demand can be obtained directly or calculated based on the material demand information.

[0054] Figure 4 is a flow chart of step S220 provided in an embodiment of the present application, specifically as follows Figure 4 As shown, step S220 may include the following steps:

[0055] S221: Calculate the material quota of each demander in the current time unit according to the total material supply in the current time unit and the first material allocation ratio information to obtain the first material quota information.

[0056] Among them, the first material quota information is used to limit the upper limit of the number of materials that each demander can obtain in the initial allocation within the current time unit. Specifically, for example, the time unit is a week, and the total material supply this week is 100k, the actual inventory of this week, and there are no materials in transit and supplier commitments. A certain enterprise has two factories, Factory A and Factory B. The first material allocation ratio corresponding to Factory A is 60%, and the first material allocation ratio corresponding to Factory B is 40%. Then, theoretically speaking, Factory A can be allocated 100k*60% of materials this week, and Factory B can be allocated 100k*40% of materials. Then the material quota of Factory A in the initial allocation of this week is 60k, and the material quota of Factory B in the initial allocation of this week is 40k.

[0057] Figure 5 is a flow chart of step S221 provided in an embodiment of the present application, and the specific example is as follows Figure 5 As shown, in some embodiments, step S221 may include the following steps:

[0058] S221a: Calculate the material quota of each demander in the current time unit according to the total material supply in the current time unit and the first material allocation ratio information to obtain a first quota calculation result.

[0059] S221b: Based on the first quota calculation result, the minimum packaging quantity is taken from the material quota of each demander in the current time unit to obtain a second quota calculation result.

[0060] In actual applications, the material quotas of each demander in the current time unit obtained in step S221a may not meet the minimum packaging quantity requirements. Specifically, for example, the allocated material is a battery, the total material supply in the current time unit is 100, and the first material allocation ratio of demander A is 33.33%. Then the calculated first quota of demander A is 33.33%*100 batteries=33.33 batteries, which obviously does not meet the actual allocation needs. When the minimum packaging quantity of the battery is 1, the first quota 33.33 can be taken up to the minimum packaging quantity to obtain a second quota of 34. When the minimum packaging quantity of the battery is 5, the first quota 33.33 can be taken up to the minimum packaging quantity to obtain a second quota of 35. It should be noted that when the material is a battery, the unit of the material quota can be "piece". When the type of material changes or according to actual needs, the material quota can also use other units of measurement. The type of measurement unit used does not affect the implementation of this embodiment.

[0061] S221c: Determine whether the sum of the material quotas of each demander in the second quota calculation result is equal to the total material supply in the current time unit.

[0062] As mentioned above, the first material allocation ratio of demander B is 33.33%, the first material allocation ratio of demander C is 33.34%, the first material quota of demander B is 33.33, and the first material quota of demander C is 33.34. Determine whether the sum of the first material quotas of demanders A, B, and C is equal to the total material supply of 100 in the current time unit.

[0063] S221d: If not, adjust the second quota calculation result according to the total material supply of the current time unit, the first material allocation ratio information and the preset allocation order, until the sum of the material quotas of each demander in the adjusted second quota calculation result is equal to the total material supply of the current time unit, and use the adjusted second quota calculation result as the first material quota information.

[0064] The preset allocation order is the demand order. The demand order can be determined according to the material demand of each demander in descending order or in descending order. For multiple demanders with the same demand quantity, they can also be sorted according to the order of demand submission time. The earlier the material demand is submitted, the higher the order.

[0065] S221e: If yes, the second quota calculation result is used as the first material quota information. Step S221e belongs to the situation where the second quota of each demander just meets the minimum packaging quantity requirement.

[0066] In an alternative embodiment, step S221 can also be implemented as follows: based on the first quota calculation result, the minimum packaging quantity is taken from the material quota of each demander in the current time unit in turn, and the decimal part is allocated according to the actual remaining material quantity to obtain the first material quota information. Specifically, still taking the allocated material as batteries as an example, the total material supply in the current time unit is 100, the minimum packaging quantity of batteries is 5, the first material allocation ratio of demander A is 33.33%, the first material allocation ratio of demander B is 33.33%, and the first material allocation ratio of demander C is 33.34%. The first material quota of demander A is 33.33, the first material quota of demander B is 33.33, and the first material quota of demander C is 33.34. Based on the first quota calculation result, the minimum packaging quantity is taken from the material quota of each demander in the current time unit in turn, and the second material quota of demander A is 35, and the second material quota of demander B is 35. The remainder is allocated to demander C according to the actual remaining material quantity: total material supply 100 - demander A's second material quota 35 - demander B's second material quota 35 = 30, that is, demander C's second material quota is 30.

[0067] S222: Perform material allocation based on the total material supply of the current time unit, the material demand information, and the first material quota information to obtain first material allocation information.

[0068] The first material allocation information includes the material allocation quantity of each demander in the current time unit.

[0069] Based on the above, for example, the material demand information is that the demand of Factory A is proposed on Monday, and the demand of Factory B is proposed on Friday. Factory A actually requires 80k materials, and the material quota of Factory A this week is 60k. Then on Monday, the materials are allocated to Factory A according to the weekly quota of 60k. At this time, Factory A has a material gap of 20k. On Friday, the remaining 40k materials are preferentially allocated to Factory B. When the initial allocation is completed, if there are still remaining materials, they will be allocated to Factory A, the demander with a material gap. In other words, if the actual material demand of Factory B is 30k, then the remaining 10k materials will be allocated to Factory A. At this time, the material gap of Factory A changes from 20k to 10k, and the 10k material gap is transferred to the next time unit. If the actual material demand of B is 40k, then there is no remaining material, and the material gap of Factory A is still 20k, and the 20k material gap is transferred to the next time unit.

[0070] Figure 6 is a flow chart of step S222 provided in an embodiment of the present application, and the specific example is as follows Figure 6 As shown, step S222 may include the following steps:

[0071] S222a: Determine whether the material quota of each demander in the current time unit is at least partially greater than its material demand.

[0072] S222b: When the material quota of each demander in the current time unit is at least partially greater than its material demand, determine the smaller value between the material quota and the material demand corresponding to each demander in the current time unit based on the first material quota information and the material demand information.

[0073] S222c: Using the smaller value as the material quantity allocated to each demander in the current time unit for initial material allocation, and obtaining a first initial material allocation result.

[0074] S222d: Calculate the remaining material supply quantity after the initial material allocation according to the total material supply quantity of the current time unit and the first initial material allocation result.

[0075] S222e: Allocate the remaining material supply quantity to the demanders whose demands are not met, and obtain the first and second material allocation results.

[0076] Among them, the material quota corresponding to the demander whose demand is not met in the current time unit is less than the material demand.

[0077] In this embodiment, allocating the remaining material supply quantity to the demand party whose demand is not met may include the following steps: determining the demand order of each demand party according to the material demand information and the second preset rule. Allocating the remaining material supply quantity to the unmet demand party in the demand order. Among them, determining the demand order of each demand party according to the material demand information and the second preset rule may include the following steps: sorting each demand party according to the size of the material demand in the material demand information to obtain a first sorting result. When there are no multiple demand parties with the same order in the first sorting result, the first sorting result is used as the demand order. When there are multiple demand parties with the same order in the first sorting result, the multiple demand parties with the same order are sorted according to the order of the demand time points in the material demand information to obtain a second sorting result. The first sorting result is updated based on the second sorting result, and the updated first sorting result is used as the demand order. That is, the demand order can be sorted from small to large or from large to small according to the demand quantity. Specifically, for example, the actual demands corresponding to demand party A, demand party B and demand party C are: A=60, B=50, C=40 respectively. Sort by demand quantity from small to large, give priority to those with small demand, and the order of demand is C, B, A. Sort by demand quantity from large to small, give priority to those with large demand, and the order of demand is A, B, C. In addition, for multiple demanders with the same demand quantity, you can also sort them according to the order of demand submission time. The earlier the material demand is submitted, the higher the order.

[0078] S222f: Based on the first primary material allocation result and the first secondary material allocation result, the material quantity allocated to each demander in the current time unit is summed to obtain first material allocation information.

[0079] In some embodiments, after step S222a, the following steps may also be included: S222g: when the material quota of each demander in the current time unit is not greater than its material demand, the first material quota information is used as the first material allocation information.

[0080] S223: Calculate the material allocation ratio of each demander corresponding to each time point in the current time unit based on the material demand information and the first material allocation ratio information to obtain the second material allocation ratio information.

[0081] Figure 7 is a flow chart of step S223 provided in an embodiment of the present application, specifically as follows Figure 7 As shown, in some embodiments, calculating the material allocation ratio of each demander corresponding to each time point in the current time unit based on the material demand information and the first material allocation ratio information to obtain the second material allocation ratio information may include the following steps:

[0082] S223a: Determine the demand party participating in the allocation corresponding to each time point in the current time unit according to the material demand information. The demand party participating in the allocation has material demand at the time point when it participates in the allocation.

[0083] S223b: Obtaining the material allocation ratio corresponding to the demander participating in the allocation based on the first material allocation ratio information.

[0084] S223c: Calculate the ratio of the material allocation ratio corresponding to each demand party participating in the allocation to the sum of the material allocation ratios of all demand parties participating in the allocation, and use the ratio as the material allocation ratio of the demand parties participating in the allocation.

[0085] S224: Calculate the material quota of each demander at each time point in the current time unit according to the material supply information and the second material allocation ratio information to obtain the second material quota information.

[0086] S225: Perform material allocation based on the material supply information, the material demand information, the first material quota information and the second material quota information to obtain a material allocation result.

[0087] Specifically, for example, suppose that materials are distributed among 4 factories, with factory A accounting for 30%, factory B accounting for 30%, factory C accounting for 20%, and factory D accounting for 20%. Assuming that only A and C have demand on the first day, and B and D have no demand, then the ratio on the first day is A:C=30%:20%=3:2, that is, A accounts for 60% and B accounts for 40%. The total supply this week = 100, of which 100 includes inventory and materials in transportation by suppliers on the road. The actual materials in the warehouse on the first day are 60, and the supply on the first day of this week = 60. The first material quota of factory A = 30, the first material quota of factory B = 30, the first material quota of factory C = 20, and the first material quota of factory D = 20. Assuming that A and C have demand on the first day, the second material quota of factory A = 36, and the second material quota of factory C = 24. The demand of ABCD is 50 each. Since the quota is limited, it means that our actual allocation on the first day is only 30 for A and 20 for C. Although there is a supply of 60 on the first day, due to the limited quotas for A and C, A can only get 30 and C can only get 20 on the first day. The remaining 10 on the first day needs to be reserved for B and D.

[0088] In some embodiments, step S225 may include the following steps: obtaining the material demand corresponding to each demander at the current time point based on the material demand information. Obtaining the material quota of the current time unit corresponding to each demander based on the first material quota. Obtaining the material quota corresponding to each demander at the current time point based on the second material quota. Determining the minimum value among the material demand corresponding to each demander at the current time point, the material quota of the current time unit, and the material quota at the current time point. Using the minimum value as the material allocation amount of each demander at the current time point for the initial material allocation, and obtaining the second initial material allocation result. Calculating the remaining material supply quantity after the initial material allocation based on the material supply quantity at the current time point and the second initial material allocation result. Allocating the remaining material supply quantity to the demander whose demand is not met and obtaining the second secondary material allocation result. Based on the second initial material allocation result and the second secondary material allocation result, summing the material quantity allocated to each demander at the current time point to obtain the second material allocation information.

[0089] In this embodiment, allocating the remaining material supply quantity to the demand party whose demand is not met includes: determining the demand order of each demand party according to the material demand information and the second preset rule. Allocating the remaining material supply quantity to the unmet demand party in the demand order. Among them, determining the demand order of each demand party according to the material demand information and the second preset rule may include the following steps: sorting each demand party according to the size of the material demand in the material demand information to obtain a first sorting result. When there are no multiple demand parties with the same order in the first sorting result, the first sorting result is used as the demand order. When there are multiple demand parties with the same order in the first sorting result, the multiple demand parties with the same order are sorted according to the order of the demand time points in the material demand information to obtain a second sorting result. The first sorting result is updated based on the second sorting result, and the updated first sorting result is used as the demand order. Specifically, for example, if the material gaps generated before the current time unit are piled up in the current time unit, it may cause one or several demand parties to have particularly large demands. If the material preparation of one or several demand parties is unreasonable, the demand of other organizations / factories will be misappropriated, which will increase the burden on organizations and enterprises with standardized management. To address this issue, the embodiment of the present application will give priority to meeting the material demand of the current time unit when performing material allocation calculations. After meeting the material demand of the current time unit, if there is any remaining part, the material gap generated before the current time unit will be considered.
