Description

Technical Field

[0001] The present application relates to the field of logistics technology, and in particular to a supply method, system, device and storage medium based on a logistics platform. Background Art

[0002] Logistics refers to the entire process of planning, implementing and managing the transportation, storage, distribution and other means of raw materials, semi-finished products, finished products and related information from the place of production to the place of consumption of the goods in order to meet the needs of customers at the lowest cost.

[0003] When the enterprise establishes demand connection with the supply side, the required materials are supplied through logistics. When supplying enterprises, logistics mainly consists of the transportation, warehousing, packaging, handling and loading and unloading, circulation processing, and related logistics information of goods.

[0004] With respect to the above-mentioned related technologies, the inventors have found the following defects: when supplying materials, since the demand is dynamically adjusted over time, and the supply of materials through logistics also takes a certain amount of time, when the supply of materials is completed, there is a tendency for the supply to be mismatched with the actual demand. Summary of the invention

[0005] In order to improve the matching rate between the supply quantity and the actual demand quantity during supply, the present application provides a supply method, system, device and storage medium based on a logistics platform.

[0006] In the first aspect, the present application provides a supply method based on a logistics platform, which adopts the following technical solution:

[0007] A supply method based on a logistics platform, comprising:

[0008] Obtain the initial demand for materials and the storage capacity of each supplier;

[0009] Analyze and determine the initial suppliers that meet the initial demand for materials based on the initial demand for materials and the storage capacity of each supplier;

[0010] According to the location points corresponding to the initial suppliers that meet the initial demand, the preset demand location points and the preset transportation speed, the estimated transportation time corresponding to the location points of the initial suppliers and the demand location points is analyzed and determined, and the estimated transportation time is sorted in a positive order, and the estimated transportation time with the first positive order is selected as the initial estimated transportation time, and the positive order is defined as the time is sorted from small to large;

[0011] According to the historical material demand change speed and initial estimated transportation time of the preset demand location point, the demand change within the initial estimated transportation time is analyzed and calculated, and added to the initial demand for materials to predict the actual demand for materials;

[0012] Analyze and determine whether the storage capacity of the selected supplier is greater than or equal to the actual demand for the predicted materials;

[0013] If yes, the selected supplier will be used as the supplier of materials for the demand location this time;

[0014] If not, exclude the currently selected supplier and jump to analyzing and determining the estimated transportation time corresponding to the initial supplier's location point and the demand location point. Re-analyze and determine the estimated transportation time corresponding to the initial supplier's location point and the demand location point, and sort the estimated transportation time in forward order. Select the estimated transportation time that is first in the forward order as the initial estimated transportation time.

[0015] By adopting the above technical scheme, the initial supplier that meets the initial demand for materials is determined through analysis of the initial demand for materials and the storage capacity of each supplier, and the actual demand for materials is predicted based on the estimated transportation time of the initial supplier. The supplier of materials at the supply demand location point this time is selected based on the judgment result of whether the storage capacity of the selected supplier is greater than the predicted actual demand for materials, so that the supply quantity provided by the supplier of materials at the supply demand location point this time is not much different from the actual demand quantity, and finally the purpose of improving the matching rate between the supply quantity and the actual demand quantity during supply is achieved.

[0016] Optionally, the analysis and calculation of the demand change within the initial estimated transportation time includes:

[0017] Obtain the data volume of the historical material demand change rate of the preset demand location point;

[0018] If the data volume of the historical material demand change speed is less than the preset first data volume, then according to the preset correspondence relationship between different types of areas and the historical material demand change speed, analyze and determine the correspondence relationship between the historical material demand change speed of the same type of area as the area where the preset demand location point is located;

[0019] According to the correspondence between the historical material demand change speed of the same type of area as the preset demand location point and the initial estimated transportation time, the demand change within the initial estimated transportation time is analyzed and calculated;

[0020] If the data volume of the historical material demand change speed exceeds the preset first data volume and is less than the preset second data volume, the historical material demand change speed of the current demand location point is predicted and obtained according to the preset historical material demand change speed of the demand location point, the preset correspondence between different types of areas and the historical material demand change speed, and the preset material demand change speed prediction formula;

[0021] According to the forecast, the historical material demand change speed and initial estimated transportation time of the demand location are obtained, and the demand change within the initial estimated transportation time is analyzed and calculated;

[0022] If the data volume of the historical material demand change speed exceeds the preset second data volume, the demand change within the initial estimated transportation time is analyzed and calculated based on the historical material demand change speed and the initial estimated transportation time of the preset demand location point.

[0023] By adopting the above technical solution, the data volume of the historical material demand change speed is compared with the preset first data volume and the preset second data volume respectively, so that different methods are used to analyze and calculate the demand change within the initial estimated transportation time, thereby improving the accuracy of the obtained demand change.

[0024] Optionally, the preset material demand change rate prediction formula is as follows:

[0025] V0=[A / (A+B)]*V1+[B / (A+B)]*V2;

[0026] V0 is the change rate of historical material demand at the current demand location;

[0027] V1 is the historical material demand change rate at the demand location point;

[0028] A is the number of changes in the historical material demand at the demand location;

[0029] V2 is the rate of change of historical material demand in different types of regions;

[0030] B is the number of historical material demand change rates in different types of regions.

[0031] By adopting the above technical solution, the historical material demand change speed of the preset demand location point is calculated by calculating the ratio of the number of historical material demand change speeds of preset different types of areas to the number of historical material demand change speeds, thereby obtaining the historical material demand change speed of the current demand location point, thereby improving the accuracy of the historical material demand change speed of the current demand location point.

[0032] Optionally, the step of analyzing and determining whether the storage capacity of the selected supplier is greater than or equal to the actual demand for the predicted acquired materials is also included:

[0033] If the number of times the analysis determines whether the storage capacity of the selected supplier is greater than or equal to the actual demand for the predicted materials is the same as the number of initial suppliers determined by the analysis to meet the initial demand for the materials, then based on the location points corresponding to the initial supplier combination that meets the initial demand, the preset demand location points and the preset transportation speed, the estimated transportation time corresponding to the location points and demand location points of the initial supplier combination is analyzed and confirmed, and the initial supplier combination is defined as two initial suppliers.

[0034] By adopting the above technical scheme, when the number of times the storage capacity of the selected supplier is analyzed to determine whether it is greater than or equal to the actual demand for the predicted materials is the same as the number of initial suppliers determined by analysis to meet the initial demand for the materials, the initial supplier combination is adopted as the supplier of the materials for this supply demand location point, so that the suppliers of the materials for this supply demand location point selected can all meet the requirements of the materials, thereby achieving the purpose of improving the matching rate between the supply and the actual demand during supply.

[0035] Optionally, the estimated transportation time corresponding to the location point and the demand location point of the initial supplier combination is analyzed and confirmed, including:

[0036] Obtain the location point corresponding to the initial supplier combination that meets the initial demand;

[0037] According to the location points corresponding to the initial supplier combination that meets the initial demand and the preset demand location points, two estimated transportation distances corresponding to the location points corresponding to the initial supplier combination and the demand location points are analyzed and confirmed;

[0038] According to the two estimated transportation distances and the preset transportation speeds, two estimated transportation times corresponding to the estimated transportation distances are analyzed and confirmed, and the two estimated transportation distances are defined as a first estimated transportation time and a second estimated transportation time respectively;

[0039] Determining whether the first estimated transportation time is greater than the second estimated transportation time;

[0040] If the first estimated transportation time is greater than the second estimated transportation time, the first estimated transportation time shall be used as the estimated transportation time;

[0041] Otherwise, the second estimated transportation time is used as the estimated transportation time.

[0042] By adopting the above technical solution, the estimated transportation time required between the two location points corresponding to the initial supplier combination and the demand location point is compared respectively, so that the larger of the two estimated transportation times is used as the final estimated transportation time, thereby facilitating the subsequent analysis and calculation when using the final estimated transportation time, and improving the accuracy of the obtained demand change.

[0043] Optionally, the following steps are included after the selected supplier is used as the supplier of the material at the supply demand location:

[0044] Obtain the remaining material quantity of the supplier after completing this transportation and the demand quantity at the demand location within the preset distance range of the preset demand location point;

[0045] According to the demand at the demand location within the preset distance range of the preset demand location point and the in-transit transportation volume at the demand location within the preset distance range of the corresponding preset demand location point, the difference demand at the demand location within the preset distance range of the preset demand location point is analyzed and obtained, and the difference demand is sorted in a positive order, and the positive order is defined as sorting the difference demand from small to large;

[0046] According to the positive sorting of the difference demand quantity, assign number values ​​to different demand positions one by one;

[0047] According to the comparison result of the difference demand quantity and the remaining material quantity of the demand position with the first number value, it is determined whether to continue to supply the demand position with the first number value;

[0048] If the difference demand quantity at the demand position with the first number value is greater than the remaining material quantity, the supply to the demand position with the first number value will not continue;

[0049] Otherwise, continue to supply the demand position with the first number value.

[0050] By adopting the above technical solution, by judging the size between the remaining material quantity of the supplier after completing this transportation and the minimum difference demand quantity at the demand location within the preset distance range of the preset demand location point, it is judged whether it is necessary to supply the demand location with the minimum difference demand quantity within the preset distance range of the preset demand location point, thereby improving the matching rate between the supply quantity and the actual demand quantity.

[0051] Optionally, the step after continuing to supply the demand position with the first number value is:

[0052] Obtain the difference demand quantity at the demand location within the preset distance range of the preset demand location point and the remaining material quantity of the supplier after completing this transportation;

[0053] According to the difference demand quantity at the demand position with the first number value and the remaining material quantity of the supplier after completing this transportation, analyze and obtain the remaining material quantity of the supplier at the completed demand position, exclude the demand position with the first number value, and re-sort the difference demand quantity in a positive order;

[0054] According to the comparison result of the difference demand quantity at the demand position with the first number value and the remaining material quantity, it is determined whether to continue to supply the demand position with the first number value;

[0055] If the difference demand quantity at the demand position with the first number value is greater than the remaining material quantity, the supply to the demand position with the first number value will not continue;

[0056] Otherwise, continue to supply the demand position with the first number value, jump to the demand position with the first exclusion number value, and re-sort the difference demand in forward direction. According to the difference demand at the demand position with the first new number value and the remaining material quantity of the supplier after completing this transportation, analyze and obtain the remaining material quantity of the supplier at the completed demand position.

[0057] By adopting the above technical solution, by continuing to judge the size of the remaining material quantity and the minimum difference demand at the demand location, it is determined whether it is necessary to continue to supply the demand location with the minimum difference demand within a preset distance range of the preset demand location point, thereby improving the matching rate between the supply quantity and the actual demand quantity.

[0058] In the second aspect, the present application provides a supply system based on a logistics platform, which adopts the following technical solutions:

[0063] The third analysis module is used to: analyze and calculate the demand change within the initial estimated transportation time according to the historical material demand change speed of the preset demand location point and the initial estimated transportation time, and add it to the initial demand for materials to predict the actual demand for materials;

[0064] The fourth analysis module is used to: analyze and determine whether the storage capacity of the selected supplier is greater than or equal to the actual demand for the predicted materials;

[0065] An execution module is used for: if yes, taking the selected supplier as the supplier of materials for the supply demand location point this time;

Re-analyze and determine the estimated transportation time corresponding to the initial supplier's location point and the demand location point, and sort the estimated transportation time in forward order. Select the estimated transportation time that is first in the forward order as the initial estimated transportation time.

[0067] By adopting the above technical solution, the initial demand for materials and the storage capacity of each supplier are acquired through the acquisition module and transmitted to the first analysis module. The first analysis module analyzes and determines the initial supplier that meets the initial demand for materials and transmits it to the second analysis module. The second analysis module analyzes and determines the estimated transportation time corresponding to the location point and the demand location point of the initial supplier and transmits it to the third analysis module. The third analysis module predicts the actual demand for materials and transmits it to the fourth analysis module for judgment. The execution module executes according to the judgment result of the fourth analysis module, thereby determining the supplier of materials at the supply demand location point this time, and finally achieving the purpose of improving the matching rate between the supply and the actual demand.

[0068] In a third aspect, the present application provides a supply device based on a logistics platform, which adopts the following technical solution:

[0069] A supply device based on a logistics platform comprises a memory and a processor, wherein the memory stores a computer program that can be loaded by the processor and execute any method in the first aspect.

[0086] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-7 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0087] The embodiment of the present application discloses a supply method based on a logistics platform.

[0088] When supplying materials, since the demand is adjusted dynamically with the change of time, and the supply of materials through logistics also takes a certain amount of time, when the materials are supplied, the supply and actual demand are prone to mismatch. The initial supplier that meets the initial demand for materials is determined by analyzing the initial demand for materials and the storage capacity of each supplier, and the actual demand for materials is obtained based on the estimated transportation time of the initial supplier. The supplier of materials at the supply demand location is selected based on the judgment result of whether the storage capacity of the selected supplier is greater than the actual demand for materials obtained by prediction, so that the supply provided by the supplier of materials at the supply demand location is not much different from the actual demand, and finally the purpose of improving the matching rate between the supply and the actual demand is achieved during supply.

[0089] Reference Figure 1 , a supply method based on a logistics platform includes:

[0090] Step S100, obtaining the initial demand for materials and the storage capacity of each supplier.

[0091] The initial demand for materials refers to the amount of materials that the enterprise needs on the day of purchase. The storage capacity of each supplier refers to the amount of materials that the supplier has stored and can provide.

[0092] Step S200, analyzing and determining the initial supplier that meets the initial demand for materials based on the initial demand for materials and the storage capacity of each supplier.

[0093] Among them, the initial supplier that meets the initial demand for materials refers to the initial supplier that stores and can provide materials that are greater than the amount of materials required by the enterprise on the day of purchase. By comparing the initial demand for materials with the storage capacity of each supplier one by one, it is possible to find out which initial suppliers can meet the initial demand for materials.

[0094] Step S300, based on the location point corresponding to the initial supplier that meets the initial demand, the preset demand location point and the preset transportation speed, analyze and determine the estimated transportation time corresponding to the location point of the initial supplier and the demand location point, sort the estimated transportation time in forward order, and select the estimated transportation time that is ranked first in the forward order as the initial estimated transportation time.

[0095] The demand location point is obtained by querying from a database storing the demand location points, and the transportation speed is obtained by querying from a database storing the transportation speed. The distance between the initial supplier meeting the initial demand and the demand location point is determined by the location point corresponding to the initial supplier meeting the initial demand and the preset demand location point, and then the estimated transportation time corresponding to the location point of the initial supplier and the demand location point is determined by analysis based on the transportation speed and the distance between the initial supplier meeting the initial demand and the demand location point.

[0096] The forward sorting is defined as sorting from the smallest time to the largest time. By selecting the estimated transportation time that is the first in the forward sorting as the initial estimated transportation time, the selected initial estimated transportation time is the shortest time.

[0097] Step S400, according to the historical material demand change speed of the preset demand location point and the initial estimated transportation time, the demand change within the initial estimated transportation time is analyzed and calculated, and added to the initial demand for materials to predict the actual demand for materials.

[0098] The historical material demand change rate of the demand location point is obtained by querying from a database storing the historical material demand change rate of the demand location point. The historical material demand change rate of the demand location point refers to the change rate of the material demand of the demand location point in each historical time period.

[0099] By analyzing the historical material demand change rate at the demand location point, the demand change within the initial estimated transportation time is calculated, and then by adding the demand change to the initial demand, the actual demand of the enterprise for the material after the initial estimated transportation time is predicted.

[0100] Step S500, analyzing and judging whether the storage capacity of the selected supplier is greater than or equal to the actual demand for the predicted acquired materials. If yes, executing step S600; executing step S700.

[0101] Among them, judging whether the storage volume of the selected supplier is greater than or equal to the actual demand volume of the predicted acquired materials refers to comparing the storage volume of the selected supplier with the actual demand volume of the predicted acquired materials.

[0102] Step S600: The selected supplier is used as the supplier of materials for the demand location point this time.

[0103] Among them, when the storage capacity of the selected supplier is greater than or equal to the actual demand for the predicted materials, it means that the selected supplier can meet the initial demand for the materials at this time, so the selected supplier is used as the supplier of the materials at the supply demand location point this time.

[0104] Step S700, exclude the currently selected supplier and jump to step S300.

[0105] Among them, when the storage capacity of the selected supplier is less than the actual demand for the predicted materials, it means that the selected supplier cannot meet the initial demand for the materials, so it is necessary to re-analyze and determine the supplier.

[0106] The implementation principle of the above steps is as follows: by obtaining the initial demand for materials and the storage capacity of each supplier, the initial supplier that can meet the initial demand for materials is determined, and by calculating the estimated transportation time between the initial supplier and the demand location point, it is determined whether the enterprise's demand changes when the materials are transported from the supplier to the demand location point, so as to predict the actual demand for materials when they are transported, so as to plan the demand for materials in advance, so that the amount of materials transported to the demand point is not much different from the actual amount of materials required. And by judging whether the storage capacity of the selected supplier is greater than or equal to the actual demand for the predicted materials, it is judged whether the selected supplier meets the requirements. If not, the estimated transportation time corresponding to the location point and the demand location point of the initial supplier is re-analyzed and determined, and the estimated transportation time is sorted in a positive order, and the estimated transportation time with the first positive order is selected as the initial estimated transportation time. Therefore, the actual demand for materials is re-predicted based on the initial estimated transportation time, and the selected initial supplier is re-judged until the selected initial supplier can meet the actual demand.

[0107] exist Figure 1 In step S400, in order to further ensure the rationality of obtaining the demand change amount within the initial estimated transportation time, it is necessary to analyze and calculate the demand change amount within the initial estimated transportation time for further separate analysis and calculation, specifically by Figure 2 The steps shown are explained in detail.

[0108] Reference Figure 2 , the analysis and calculation of the demand change within the initial estimated transportation time includes the following steps:

[0109] Step S410, obtaining data on the historical material demand change rate of a preset demand location point.

[0110] The data volume of the historical material demand change speed of the demand location point is obtained by querying from a database storing the data volume of the historical material demand change speed of the demand location point. The data volume of the historical material demand change speed of the demand location point refers to the number of information about the historical material demand change speed of the demand location point in the database.

[0111] Step S420, if the data volume of the historical material demand change speed is less than the preset first data volume, then according to the preset correspondence between different types of areas and the historical material demand change speed, analyze and determine the correspondence between the historical material demand change speed of the same type of area as the area where the preset demand location point is located.

[0112] The first data volume is obtained by querying from a database storing the first data volume. The speed of change of different types of regions and historical material demand is obtained by querying from a database storing different types of regions and historical material demand change speed. The speed of change of different types of regions and historical material demand refers to the speed of change of material demand in different types of regions and different types of regions in different historical time periods.

[0113] When the amount of data on the change rate of historical material demand is less than the preset first amount of data, it means that the amount of data on the change rate of historical material demand is too small to calculate the change in demand within the initial estimated transportation time. By comparing the change rates of historical material demand in different types of areas, the change rates of historical material demand in the same type of area where the preset demand location is located can be inferred.

[0114] Step S430, based on the correspondence between the historical material demand change speed of the same type of area as the preset demand location point and the initial estimated transportation time, analyze and calculate the demand change within the initial estimated transportation time.

[0115] Among them, the initial estimated transportation time analysis is used to calculate the change rate of material demand in the same type of area as the preset demand location point within the initial estimated transportation time, thereby predicting the change in demand at the demand location point within the initial estimated transportation time.

[0116] Step S440, if the data volume of the historical material demand change speed exceeds the preset first data volume and is less than the preset second data volume, then based on the preset historical material demand change speed of the demand location point, the correspondence between the preset different types of areas and the historical material demand change speed, and the preset material demand change speed prediction formula, the historical material demand change speed of the current demand location point is predicted.

[0117] The second data volume is obtained by querying from a database storing the second data volume. The second data volume is greater than the first data volume. When the data volume of the historical material demand change speed exceeds the preset first data volume and is less than the preset second data volume, it indicates that the data volume of the historical material demand change speed at this time can analyze and calculate the demand change within the initial estimated transportation time with a certain accuracy.

[0118] By applying the preset material demand change rate prediction formula, the historical material demand change rate of the current demand location point is predicted by combining the preset historical material demand change rate of the demand location point with the preset different types of areas and historical material demand change rates.

[0119] The preset material demand change rate prediction formula is as follows:

[0120] V0=[A / (A+B)]*V1+[B / (A+B)]*V2;

[0121] V0 is the change rate of historical material demand at the current demand location;

[0122] V1 is the historical material demand change rate at the demand location point;

[0123] A is the number of changes in the historical material demand at the demand location;

[0124] V2 is the rate of change of historical material demand in different types of regions;

[0125] B is the number of historical material demand change rates in different types of regions.

[0126] For example, when V1=2, V2=6, A=5, B=5,

[0127] V0=[A / (A+B)]*V1+[B / (A+B)]*V2=[5 / (5+5)]*2+[5 / (5+5)]*6=4.

[0128] Step S450, obtaining the historical material demand change speed and initial estimated transportation time of the current demand location point according to the prediction, and analyzing and calculating the demand change within the initial estimated transportation time.

[0129] Among them, the historical material demand change rate of the current demand location point is obtained through the initial estimated transportation time and prediction, and the demand change within the initial estimated transportation time is analyzed and calculated.

[0130] Step S460, if the data volume of the historical material demand change speed exceeds the preset second data volume, the demand change within the initial estimated transportation time is analyzed and calculated based on the historical material demand change speed of the preset demand location point and the initial estimated transportation time.

[0131] When the data volume of the historical material demand change speed exceeds the preset second data volume, it means that the data volume of the historical material demand change speed at this time can analyze and calculate the demand change within the initial estimated transportation time with high accuracy. Therefore, the demand change within the initial estimated transportation time is analyzed and calculated directly through the historical material demand change speed of the demand location point and the initial estimated transportation time.

[0132] The implementation principle of the above steps is as follows: by determining the data volume of the historical material demand change rate and comparing it with the preset first data volume and the preset second data volume respectively, different methods are selected according to the amount of data of the historical material demand change rate to analyze and calculate the demand change within the initial estimated transportation time, thereby improving the accuracy of the demand change within the initial estimated transportation time.

[0133] exist Figure 1 After step S500, in order to further ensure the rationality of obtaining the initial supplier, it is necessary to further analyze and calculate the initial supplier separately, specifically through Figure 3 The steps shown are explained in detail.

[0134] Reference Figure 3 , after analyzing and judging whether the storage capacity of the selected supplier is greater than or equal to the actual demand for the predicted materials, the following steps are included:

[0135] Step S510, if the number of times the analysis determines whether the storage capacity of the selected supplier is greater than or equal to the predicted actual demand for the materials is the same as the number of initial suppliers determined by the analysis to meet the initial demand for the materials, then based on the location points corresponding to the initial supplier combination that meets the initial demand, the preset demand location points and the preset transportation speed, analyze and confirm the estimated transportation time corresponding to the location points and demand location points of the initial supplier combination.

[0136] The number of times of analyzing and judging whether the storage capacity of the selected supplier is greater than or equal to the actual demand for the predicted materials refers to the number of times the storage capacity of the selected supplier is judged against the actual demand for the predicted materials. If the number of times of analyzing and judging whether the storage capacity of the selected supplier is greater than or equal to the actual demand for the predicted materials is the same as the number of initial suppliers determined by analyzing to meet the initial demand for materials, it means that the material storage capacity of the initial suppliers meeting the initial demand for materials is less than the actual demand for the predicted materials.

[0137] The initial supplier combination is defined as two initial suppliers. When a single supplier cannot provide independent material supply, two initial suppliers are selected so that the material quantity stored by the two initial suppliers can meet the material quantity of the demand point. The estimated transportation time is confirmed by analyzing the location points corresponding to the two initial suppliers, the preset demand location points and the preset transportation speed, and the estimated transportation time is used to judge whether the storage quantity of the initial supplier combination can meet the actual demand.

[0138] exist Figure 1 In step S510, in order to further ensure the rationality of the estimated transportation time corresponding to the location points and the demand location points of the initial supplier combination, it is necessary to further analyze and calculate the estimated transportation time corresponding to the location points and the demand location points of the initial supplier combination. Figure 4 The steps shown are explained in detail.

[0139] Reference Figure 4 , analyzing and confirming the estimated transportation time corresponding to the location points and demand location points of the initial supplier combination includes the following steps:

[0140] Step S511, obtaining the location points corresponding to the initial supplier combination that meets the initial demand.

[0141] The position points corresponding to the initial supplier combination that meets the initial demand refer to the position points corresponding to the two initial suppliers that correspond to the initial supplier combination that meets the initial demand.

[0142] Step S512, based on the location points corresponding to the initial supplier combination that meets the initial demand and the preset demand location points, two estimated transportation distances corresponding to the location points corresponding to the initial supplier combination and the demand location points are analyzed and confirmed.

[0143] Among them, through the location points corresponding to the initial supplier combination that meets the initial demand and the preset demand location points, the estimated transportation distance between the location points of the two suppliers corresponding to the initial supplier combination and the demand location point is analyzed and confirmed.

[0144] Step S513: analyzing and confirming two estimated transportation times corresponding to the estimated transportation distances according to the two estimated transportation distances and the preset transportation speeds.

[0145] The two estimated transportation distances are defined as a first estimated transportation time and a second estimated transportation time, wherein the two estimated transportation times are analyzed and confirmed through the two estimated transportation distances and the preset transportation speed.

[0146] Step S514, determining whether the first estimated transportation time is greater than the second estimated transportation time. If yes, executing step S515; if no, executing step S516.

[0147] Herein, judging whether the first estimated transportation time is greater than the second estimated transportation time refers to judging whether a parameter corresponding to the first estimated transportation time is greater than a parameter corresponding to the second estimated transportation time.

[0148] Step S515: taking the first estimated transportation time as the estimated transportation time.

[0149] When the first estimated transportation time is greater than the second estimated transportation time, it means that the time it takes for the supplier corresponding to the first estimated transportation time to transport the materials to the demand point is greater than the time it takes for the supplier corresponding to the second estimated transportation time to transport the materials to the demand point. Therefore, the first estimated transportation time is used as the estimated transportation time.

[0150] Step S516: taking the second estimated transportation time as the estimated transportation time.

[0151] Among them, when the first estimated transportation time is not greater than the second estimated transportation time, it means that the time for the supplier corresponding to the first estimated transportation time to transport the materials to the demand point is not greater than the time for the supplier corresponding to the second estimated transportation time to transport the materials to the demand point. Therefore, the second estimated transportation time is used as the estimated transportation time.

[0152] The implementation principle of the above steps is as follows: confirm two estimated transportation distances by analyzing the location points corresponding to the initial supplier combination that meets the initial demand, and confirm the corresponding two estimated transportation times based on the two estimated transportation distances, and select the larger value of the two estimated transportation times, so as to improve the accuracy of subsequent analysis and calculation results.

[0153] exist Figure 1 After step S600, in order to further ensure the rationality of the supply and demand, it is necessary to further analyze and calculate the supply and demand separately. Figure 5 The steps shown are explained in detail.

[0154] Reference Figure 5 The steps after selecting the selected supplier as the supplier of the material at the supply demand location point include the following steps:

[0155] Step S610, obtaining the remaining material quantity of the supplier after completing the current transportation and the demand quantity at the demand location within a preset distance range of the preset demand location point.

[0156] The remaining material quantity of the supplier after completing this transportation refers to the remaining material quantity after the supplier supplies the material to the demand location. The demand quantity at the demand location within the preset distance range of the preset demand location refers to the demand quantity at the demand location with demand that still exists within the preset distance range of the demand location.

[0157] Step S620, based on the demand at the demand location within the preset distance range of the preset demand location point and the in-transit transportation volume at the demand location within the preset distance range of the corresponding preset demand location point, analyze and obtain the difference demand at the demand location within the preset distance range of the preset demand location point, and sort the difference demand in forward order.

[0158] Among them, the forward sorting is defined as sorting the difference demand from small to large. The in-transit transportation volume at the demand location within the preset distance range of the corresponding preset demand location point refers to the amount of materials that have been transported on the way at the demand location with demand that still exists within the preset distance range of the demand location point. The difference demand volume at the demand location within the preset distance range of the preset demand location point refers to the amount of materials that still need to be supplied at the demand location with demand that still exists within the preset distance range of the demand location point.

[0159] By comparing the demand at the demand location within the preset distance range of the preset demand location point with the in-transit transportation volume at the demand location within the preset distance range of the corresponding preset demand location point, the difference demand at the demand location within the preset distance range of the preset demand location point is analyzed and obtained.

[0160] Step S630, assigning serial numbers to different demand positions one by one according to the forward order of the difference demand quantities.

[0161] Among them, the difference demand quantities are sorted from small to large, and number values ​​are assigned to different demand positions corresponding to the difference demand quantities sorted from small to large.

[0162] Step S640, judging whether to continue supplying the demand location with the first number value according to the comparison result of the difference demand quantity and the remaining material quantity at the demand location with the first number value.

[0163] Among them, whether the difference demand quantity at the demand position with the first number value is greater than the remaining material quantity is determined to determine whether to continue to supply the demand position with the first number value.

[0164] Step S650: If the difference demand quantity at the demand position with the first number value is greater than the remaining material quantity, supply to the demand position with the first number value will not continue.

[0165] Among them, when the difference demand at the demand position with the first number value is greater than the remaining material quantity, it means that the remaining material quantity cannot meet the required material quantity at the demand position with the first number value, and thus the supply to the demand position with the first number value will not continue.

[0166] Step S660: Otherwise, continue to supply the demand position with the first number value.

[0167] Among them, when the difference demand at the demand position with the first number value is less than the remaining material quantity, it means that the remaining material quantity can meet the required material quantity at the demand position with the first number value, thereby continuing to supply the demand position with the first number value.

[0168] The implementation principle of the above steps is as follows: by sorting and numbering the difference demand quantities at the demand locations within the preset distance range of the preset demand location point in a positive order, and comparing the difference demand quantity ranked first in the positive order with the remaining material quantity, when the difference demand quantity ranked first in the positive order is less than the remaining material quantity, it means that the remaining material quantity at this time cannot provide the material quantity still needed at the demand location within the preset distance range of the preset demand location point, and thus the demand location with the first number value will not be supplied any more. When the difference demand quantity ranked first in the positive order is greater than the remaining material quantity, it means that the remaining material quantity at this time is sufficient to provide the material quantity still needed at the demand location within the preset distance range of the preset demand location point, and thus the demand location with the first number value will continue to be supplied.

[0169] exist Figure 1After step S660, in order to further ensure the rationality of the supply and demand, it is necessary to further analyze and calculate the supply and demand separately. Figure 6 The steps shown are explained in detail.

[0170] Reference Figure 6 , the steps after continuing to supply the demand position with the first number value include the following steps:

[0171] Step S661, obtaining the difference demand quantity at the demand location within the preset distance range of the preset demand location point and the remaining material quantity of the supplier after completing this transportation.

[0172] Step S662, exclude the demand position with the first number value, and re-sort the difference demand in forward order, and analyze and obtain the remaining material quantity of the supplier at the completed demand position based on the difference demand at the demand position with the first new number value and the remaining material quantity of the supplier after completing this transportation.

[0173] Among them, by excluding the demand position with the first number value and re-sorting the difference demand in forward order, the original demand position with the second number value is sorted to the first, and the remaining material quantity of the supplier at the completed demand position is analyzed and obtained based on the difference demand quantity at the demand position with the first new number value and the remaining material quantity of the supplier after completing this transportation.

[0174] Step S663, judging whether to continue supplying the demand location with the first number value according to the comparison result of the difference demand quantity at the demand location with the first number value and the remaining material quantity.

[0175] Among them, by judging whether the difference demand quantity at the demand position with the first number value is greater than the remaining material quantity, it is judged whether to continue to supply the demand position with the first number value.

[0176] Step S664: If the difference demand quantity at the demand position with the first number value is greater than the remaining material quantity, supply to the demand position with the first number value will not continue.

[0177] Among them, when the difference demand at the demand position with the first number value is greater than the remaining material quantity, it means that the remaining material quantity at this time cannot meet the demand at the demand position with the first number value, and thus the demand position with the first number value will not be supplied any more.

[0178] Step S665: Otherwise, continue to supply the demand position with the first number value and jump to step S662.

[0179] When the difference demand at the demand position with the first number is less than the remaining material quantity, it means that the remaining material quantity at this time can meet the demand at the demand position with the first number, so the supply to the demand position with the first number continues, and it is further determined whether the supply to other demand positions can continue.

[0180] The implementation principle of the above steps is as follows: by excluding the demand locations that have been supplied, and comparing the remaining material quantity with the material quantity required at other demand locations, when the demand is met, continue to supply other demand locations.
