[0073] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0074] It should be noted that in the technical solution of the present invention, the collection, use, storage, sharing and transfer of user personal information involved are in compliance with the provisions of relevant laws and regulations, and it is necessary to inform the user and obtain the user's consent or authorization. When applicable, the user's personal information is de-identified and / or anonymized and / or encrypted.

[0075] As the logistics industry continues to develop, the number of logistics sites is gradually increasing. In order to improve logistics transportation efficiency, some target logistics sites are usually selected from multiple logistics sites as logistics hub sites. For example, the provincial capital city or a city with a large logistics business volume is selected as the target logistics site from multiple cities in a province. When selecting the target logistics site, the target site is usually determined based on the site location, transportation volume, surrounding logistics sites and other information of the logistics site.

[0076] The logistics and transportation coverage of the selected target logistics sites is relatively small, resulting in an insignificant improvement in logistics and transportation efficiency. When it is necessary to select target logistics sites that cover the entire logistics network, target logistics sites with similar logistics and transportation coverage are often selected, resulting in the need to select too many target logistics sites and low selection efficiency of target logistics sites.

[0077] In view of this, according to a first aspect of an embodiment of the present invention, a method for screening logistics sites is provided.

[0078] Figure 1 FIG. 1 is a schematic diagram of the main process of the method for selecting logistics sites according to an embodiment of the present invention. Figure 1 As shown, the method for logistics site screening according to an embodiment of the present invention mainly includes the following steps S101 to S103.

[0079] Step S101, in response to receiving a site screening request, converting a plurality of pre-set logistics sites into a logistics site map.

[0080] Logistics sites are used to temporarily store goods, transfer goods to other logistics sites, or deliver goods to the delivery address. The pre-set multiple logistics sites can be logistics sites in the same urban area, logistics sites in the same province or city, or logistics sites in multiple provinces or cities. For example, the site screening request is parsed, and the request parameters include: province A1 and province A2. The logistics sites included in province A1 and province A2 are used as multiple logistics sites for converting the logistics site map.

[0081] After receiving the site screening request, multiple logistics sites are converted into a logistics site graph. Specifically, each logistics site is taken as a vertex of the logistics site graph, and the transportation paths between multiple logistics sites are taken as edges between corresponding vertices. Since the transportation paths between logistics sites are bidirectional, the edges of the logistics site graph have no direction, and the logistics site graph is an undirected graph. The transportation path is taken as the association relationship between logistics sites. When one logistics site can reach another logistics site through one transportation path, the two logistics sites are determined to be directly associated. When multiple transportation paths are required to reach another logistics site from one logistics site, the two logistics sites are determined to be indirectly associated. The entire logistics site graph constitutes a logistics network.

[0082] For example, the logistics site graph G = (V, E), where V = {V1, V2, V3, V4}, representing the vertex set included in the logistics site graph (i.e., the four logistics sites included in the logistics site graph), and E = {(V i ,V j )|V i ∈V,V j ∈V,i≠j}, represents the edge set included in the logistics site graph (i.e., the transportation paths between the four logistics sites); vertex V1 and vertex V2 are two vertices in the vertex set V, and there is an edge E1 between vertex V1 and vertex V2, which means that there is a transportation path between the logistics site corresponding to vertex V1 and the logistics site corresponding to vertex V2.

[0083] As another example, there are four logistics stations, namely logistics station 1, logistics station 2, logistics station 3, and logistics station 4. The transportation relationship of these four logistics stations is shown in Table 1, wherein there is a transportation path between logistics station 1 and logistics station 2 and logistics station 3, there is a transportation path between logistics station 2 and logistics station 1, logistics station 3, and logistics station 4, there is a transportation path between logistics station 3 and logistics station 1, logistics station 2, and logistics station 4, and there is a transportation path between logistics station 4 and logistics station 2 and logistics station 3. Figure 2 is a schematic diagram of a logistics site map according to a reference embodiment of the present invention. Specifically, the logistics sites and transportation paths included in Table 1 are converted to obtain a logistics site map, such as Figure 2 As shown, the above four logistics sites are used as vertices of the logistics site graph, and the transportation paths between the logistics sites are used as edges of the logistics site graph.

[0084] Table 1

[0085] Serial number Logistics site Single transport route direct 1 Logistics Station 1 Logistics Station 2, Logistics Station 3 2 Logistics Station 2 Logistics Station 1, Logistics Station 3, Logistics Station 4 3 Logistics Station 3 Logistics Station 1, Logistics Station 2, Logistics Station 4 4 Logistics Station 4 Logistics Station 2, Logistics Station 3

[0086] Converting logistics sites into logistics site maps can more clearly understand the relationship between each logistics site and other logistics sites, retain only the logistics information used to determine the target logistics site, ignore other non-essential logistics information, and improve the screening efficiency of the target logistics site.

[0087] Step S102, determining the logistics transportation capacity of each logistics site according to the logistics site map.

[0088] After generating the logistics site graph, traverse each vertex of the logistics site graph to determine the logistics transport capacity of the logistics site corresponding to each vertex. The logistics transport capacity represents the transportation capacity of the logistics site, which is obtained based on multiple aspects of logistics information. The logistics information used to determine the logistics transport capacity includes: the number of cargo transfers, cargo transfer volume, cargo transfer completion time, cargo delivery number, cargo delivery volume, cargo transfer or delivery delay rate, the number of other logistics sites directly associated with the logistics site, etc. within a preset period. The logistics transport capacity of a logistics site is the sum of the logistics transport capacities of the logistics site relative to other logistics sites. Based on the above multiple aspects of logistics information, determine the logistics transport capacity of the logistics site relative to each logistics site, add up the multiple determined logistics transport capacities, and obtain the logistics transport capacity of the logistics site.

[0089] Exemplarily, to determine the logistics transportation capacity of logistics site B1, determine whether there is an association relationship between logistics site B1 and other logistics sites, that is, determine whether it is possible to reach other logistics sites from logistics site B1 through one or more transportation paths; determine that the logistics transportation capacity of logistics site B1 relative to other logistics sites that have no association relationship is equal to 0, and determine that other logistics sites that have an association relationship with logistics site B1 include: logistics site B2, logistics site B3 and logistics site B4; determine that in the past month, the number of cargo transfers of logistics site B1 relative to logistics site B2 is 5 times, the cargo transfer volume is 100 kilograms, and the cargo transfer completion time is 4 hours, and determine that in the past month, the number of cargo transfers of logistics site B1 relative to logistics site B3 is 6 times, the cargo transfer volume is 80 kilograms, and the cargo transfer completion time is 4 hours. and the cargo completion time is 8 hours, it is determined that in the past month, the number of cargo transfers of logistics site B1 relative to logistics site B3 is 3 times, the cargo transfer volume is 50 kg, and the cargo completion time is 2 hours; according to the calculation formula of logistics transportation capacity Y: Y=W1*count+W2*weight+W3*1 / time, the logistics transportation capacity of logistics site B1 relative to logistics site B2, logistics site B3 and logistics site B4 is determined, among which count represents the number of cargo transfers, W1 represents the weight of the number of cargo transfers, weight represents the cargo transfer volume, W2 represents the weight of the cargo transfer volume, time represents the cargo transfer completion time, and W3 represents the weight of the cargo transfer completion time; add the above three logistics transportation capacities to get the logistics transportation capacity of logistics site B1.

[0090] Based on logistics information from multiple aspects, the logistics transportation capacity of the logistics site relative to other logistics stations can be determined, which can comprehensively examine the logistics transportation capacity of the logistics site relative to each logistics station and improve the accuracy of the logistics transportation capacity; using the pre-set logistics transportation capacity calculation formula and the weight relationship of the logistics information to calculate the logistics transportation capacity can more flexibly determine the logistics transportation capacity of the logistics site, determine the logistics transportation capacity of the logistics site according to the importance of the logistics information, further improve the accuracy of the logistics transportation capacity, and meet the screening needs of various logistics sites.

[0091] According to a reference embodiment of the present invention, when determining the logistics transportation capacity of each logistics site according to the logistics site map, the first-order logistics site and multi-order logistics site of the logistics site are first determined in the logistics site map, wherein the first-order logistics site is a logistics site directly associated with the logistics site, that is, the first-order logistics site can be reached from the logistics site through one transportation path, and the multi-order logistics site is a logistics site indirectly associated with the logistics site, that is, the multi-order logistics site can be reached from the logistics site through multiple transportation paths. For example, Figure 2As shown, for logistics site 1, since there is a transportation path between logistics site 1 and logistics site 2 and logistics site 3, logistics site 2 and logistics site 3 are first-order logistics sites of logistics site 1. Since at least two transportation paths are required from logistics site 1 to logistics site 4, logistics site 4 is a second-order logistics site of logistics site 1. Multi-order logistics sites include second-order logistics sites.

[0092] Determine the first-order logistics transport capacity of the logistics site relative to the first-order logistics site. Specifically, determine the first-order logistics transport capacity of the logistics site relative to the first-order logistics site according to a preset logistics transport capacity calculation formula and multiple aspects of logistics information. Then determine the multi-order logistics transport capacity of the logistics site relative to the multi-order logistics site. Specifically, determine the multi-order logistics transport capacity of the logistics site relative to the multi-order logistics site according to a preset logistics transport capacity calculation formula and multiple aspects of logistics information. The logistics information includes: the number of transfers directly from the logistics site to the multi-order logistics site, the amount of goods transferred directly from the logistics site to the multi-order logistics site, the transfer time directly from the logistics site to the multi-order logistics site, and the number of transfers, the amount of goods transferred, the transfer time, etc. from the logistics site to the multi-order logistics site via one or more other sites. The weight of the logistics information obtained by direct transfer from the logistics site is greater, and the weight of the logistics information obtained by the logistics site through one or more logistics sites is smaller. After obtaining the first-order logistics transport capacity of the logistics site relative to the first-order logistics site and the multi-order logistics transport capacity relative to the multi-order logistics site, the first-order logistics transport capacity and the multi-order logistics transport capacity are added together to obtain the logistics transport capacity of the logistics site.

[0093] Exemplarily, to determine the logistics transport capacity of logistics site C1, logistics site C2 is the first-order logistics site of logistics site C1, and logistics site C3 is the multi-order logistics site of logistics site C1. Specifically, logistics site C1 needs to pass through logistics site C2 to reach logistics site C3; according to the calculation formula of the first-order logistics transport capacity Y1: Y1=Z1*volume+Z2*time, determine the first-order logistics transport capacity of logistics site C1, where volume represents the cargo transfer volume from logistics site C1 to logistics site C2, Z1 represents the weight of the cargo transfer volume, time represents the transfer time from logistics site C1 to logistics site C2, and Z2 is the weight of the transfer time; according to the calculation formula of the first-order logistics transport capacity T2: Y2=Z3*volume1+Z4*volume 2+Z5*time1+Z5*time2, determine the first-order logistics transport capacity of logistics site C1, where volume1 represents the first cargo transfer volume from logistics site C1 to logistics site C3 via logistics site C2, Z3 is the weight of the first cargo transfer volume, volume2 represents the second cargo transfer volume from logistics site C1 to logistics site C2, and then from logistics site C2 to logistics site C3, Z4 is the weight of the second cargo transfer volume, time1 represents the first transit time from logistics site C1 to logistics site C3 via logistics site C2, Z5 is the weight of the first transit time, time2 represents the second transit time from logistics site C1 to logistics site C2, and then from logistics site C2 to logistics site C3, and Z6 is the weight of the second transit time. Add the first-order logistics transport capacity and multi-order logistics transport capacity of logistics site C1 to obtain the logistics transport capacity of logistics site C1.

[0094] Determining the first-order logistics transportation capacity and multi-order logistics transportation capacity of a logistics site can determine which logistics transportation processes are directly related to the logistics site and which logistics transportation processes are indirectly related to the logistics site, thereby distinguishing the importance of different logistics transportation processes in determining the transportation capacity of the logistics site and more accurately determining the logistics transportation capacity of the logistics site.

[0095] According to another reference embodiment of the present invention, when determining the first-order logistics transport capacity of a logistics site based on the first-order logistics site of the logistics site, the logistics information entropy of the logistics site relative to the first-order logistics site is first determined. The logistics information entropy is a measure of logistics information, for example, measuring the distribution of other logistics sites around the logistics site, and for another example, measuring the transshipment information or delivery information related to the logistics site.

[0096] For example, the logistics information entropy represents the distribution of other logistics sites around the logistics site. The calculation formula of the logistics information entropy is: Among them, H vrepresents the logistics information entropy of the logistics site, Γ v represents the set of first-order logistics sites, u represents the first-order logistics site of the logistics site, p u represents the distribution probability of the first-order logistics site; specifically, p u The calculation formula is: Among them, w represents the first-order logistics site of the logistics site, k u represents the distribution probability of the first-order logistics sites included in the first-order logistics site u, k w Represents the set Γ v The distribution probability of the first-order logistics sites included in each logistics site in . The logistics information entropy of the logistics site is determined according to the above calculation formula.

[0097] For example, logistics information entropy represents the total amount of logistics information possessed by a logistics site, and the calculation formula of logistics information entropy is: Among them, H v represents the logistics information entropy of the logistics site, Γ v represents the set of first-order logistics sites, u represents the first-order logistics site of the logistics site, p u represents the probability of a logistics event between a logistics site and a first-order logistics site. For example, the probability includes: the probability that a logistics site transfers goods to each first-order logistics site, the probability that the amount of goods transferred from a logistics site to a first-order logistics site is greater than or equal to the transfer amount threshold, the probability of delay in transferring goods from a logistics site to a first-order logistics site, etc. Specifically, p u The calculation formula is: Among them, w represents the first-order logistics site of the logistics site, k u represents the total number of target logistics events between the logistics site and the first-order logistics site u, k w Represents the logistics site and the set Γ v The number of target logistics events between each logistics site in . The logistics information entropy of the logistics site is determined according to the above calculation formula.

[0098] After obtaining the logistics information entropy, the logistics information entropy is normalized. Specifically, the formula for normalizing the logistics information entropy is: in, represents the normalized logistics information entropy, LI v represents the logistics transport capacity of the logistics site v. For example, from the above two embodiments, k v Represents the set Γ v The distribution probability of the first-order logistics sites included in each logistics site or the distribution probability of the logistics sites and the set Γ vThe number of target logistics events between each logistics site in . The logistics information entropy is normalized according to the above normalization formula, and the normalized logistics information entropy is used as the first-order logistics transportation capacity of the logistics site.

[0099] Determining the logistics information entropy of a logistics site can obtain the expectation of various logistics information that a logistics site may have, which is convenient for predicting the cargo transfer and cargo delivery of the logistics site, and thus helps to accurately screen out the target logistics site. Normalizing the logistics information entropy can reduce the impact of the number of first-order logistics sites on the logistics information entropy, improve the accuracy of the logistics information entropy of the logistics site, and further more accurately screen out the target logistics site.

[0100] According to another reference embodiment of the present invention, when determining the multi-stage logistics transport capacity of a logistics site according to the multi-stage logistics sites of the logistics site, determine the transport path from the logistics site to each multi-stage logistics site, take the transport path from the logistics site to each multi-stage logistics site as the target transport path, and take the logistics sites included in each target transport path as a group of path logistics sites. Determine the first-order logistics site of the path logistics site on the target transport path, that is, determine the logistics site that can be directly reached from the path logistics site through only one transport path according to the target transport path. Determine the first-order logistics transport capacity of the path logistics site according to the first-order logistics site of the path logistics site. The method for determining the first-order logistics transport capacity of the logistics site has been described in detail in the embodiment of the present invention mentioned above, and will not be repeated here. Multiply the first-order logistics transport capacity of each path logistics site on the target transport path, that is, multiply the first-order logistics transport capacity of the same group of path logistics sites, and obtain the logistics transport capacity of the logistics site relative to the multi-stage logistics site corresponding to the target transport path. Add the logistics transport capacity of the logistics site relative to each multi-stage logistics site to obtain the multi-stage logistics transport capacity of the logistics site.

[0101] Figure 3 is a schematic diagram of a transport path according to a reference embodiment of the present invention. Figure 3 As shown in the figure, there are five logistics stations, namely, logistics station M1, logistics station M2, logistics station M3, logistics station M4, and logistics station M5. Among them, from logistics station M1 to logistics station M5, at least two transportation paths are required. Therefore, logistics station M5 is a multi-stage logistics station of logistics station M1. There are two target transportation paths from logistics station M1 to logistics station M5, namely: the first target transportation path composed of transportation path 1, transportation path 2, and transportation path 3, and the second target transportation path composed of transportation path 4 and transportation path 5. Among them, the logistics transportation capacity II of logistics station M1 obtained by the second target transportation path is M1M5 The calculation formula is: II M1M5 =IM1M3 *I M3M5 =LI M1 *LI M3 , where I M1M3 represents the logistics transport capacity of logistics site M1 relative to logistics site M3, I M3M5 Represents the logistics transport capacity of logistics site M3 relative to logistics site M5, and the logistics transport capacity II of logistics site M1 obtained by the first target transportation path M1M5 The calculation formula is: II M1M5 =I M1M2 *I M2M4 *I M4M5 =LI M1 *LI M2 *LI M4 Since there are two target transportation paths between logistics site M1 and logistics site M5, the logistics transportation capacity of logistics site M1 relative to logistics site M5 is the average of the above two logistics transportation capacities, that is, (LI M1 *LI M3 +LI M1 *LI M2 *LI M4 ) / 2.

[0102] Extending the above calculation method to general scenarios, for any second-order logistics site s in the logistics site t in the logistics site graph, the total number of paths between t and s is N ts , the first-order logistics station of the qth transportation path is r q , the logistics transport capacity of logistics site t relative to the second-order logistics site s II ts The calculation formula is: Therefore, the total logistics transport capacity of the second-order logistics site of logistics site t is: Among them, Q t is the total number of second-order logistics sites of logistics site t, s q It is the qth second-order logistics site of logistics site t.

[0103] According to the first-order logistics transport capacity of each path logistics station on the target transportation path, the multi-order logistics transport capacity of the logistics station relative to the multi-order logistics stations is determined. This can unify the calculation methods of the first-order logistics transport capacity and the multi-order logistics transport capacity, avoid different evaluation criteria for the first-order logistics transport capacity and the multi-order logistics transport capacity, and improve the accuracy of the logistics transport capacity.

[0104] According to another reference embodiment of the present invention, before adding the logistics transport capacity of the logistics site relative to each multi-stage logistics site, the method further includes: determining whether the multi-stage logistics site corresponding to each target transportation path is the same, and determining the target multi-stage logistics site that has multiple transportation paths with the logistics site, that is, the target multi-stage logistics site can be reached from the logistics site through multiple transportation paths. Take the average value of the multiple logistics transport capacities of the logistics site relative to the target multi-stage logistics site to obtain the average logistics transport capacity, and use the average logistics transport capacity as the logistics transport capacity of the logistics site relative to the target multi-stage logistics site.

[0105] Exemplarily, there are three transport paths between logistics site D1 and multi-stage logistics site D2, namely transport path F1, transport path F2, and transport path F3. Then, multi-stage logistics site D2 is used as the target multi-stage logistics site, wherein the logistics transport capacity of logistics site D1 on transport path F1 relative to target multi-stage logistics site D2 is 10, the logistics transport capacity of logistics site D1 on transport path F2 relative to target multi-stage logistics site D2 is 15, and the logistics transport capacity of logistics site D1 on transport path F3 relative to target multi-stage logistics site D2 is 11; the average value of multiple logistics transport capacities of logistics site D1 relative to target multi-stage logistics site D2 is taken, and the average logistics transport capacity is (10+15+11) / 3=12, therefore, the logistics transport capacity of logistics site D1 relative to multi-stage logistics site D2 is 12. In another exemplary embodiment, there are weights between different transport paths, and the weighted average value of multiple logistics transport capacities of multiple target multi-stage logistics sites is taken.

[0106] When there are multiple transportation paths between logistics sites and multi-stage logistics sites, taking the average of multiple logistics transportation capacities can comprehensively consider the impact of each transportation path on the logistics site and improve the accuracy of logistics transportation capacity.

[0107] Step S103, selecting a target logistics site from the multiple logistics sites according to the logistics transport capacity of each logistics site.

[0108] After determining the logistics transport capacity of each logistics site, the logistics sites are sorted in descending order according to the logistics transport capacity, or the logistics transport capacity is compared, and the logistics site with the largest logistics transport capacity is used as the target logistics site. For example, the logistics transport capacity of logistics site J1 is 30, the logistics transport capacity of logistics site J2 is 35, and the logistics transport capacity of logistics site J3 is 50. Since the logistics transport capacity of logistics site J3 is the largest, logistics site J3 is used as the target logistics site.

[0109] Taking the logistics site with the largest logistics transportation capacity as the target logistics site can expand the logistics transportation coverage of the target logistics site and improve the screening efficiency of the target logistics site.

[0110] According to a reference embodiment of the present invention, the method also includes: determining whether the number of target logistics sites is greater than or equal to a preset number threshold, the number threshold indicating the number of target logistics sites that need to be screened out from multiple logistics sites; when the number of target logistics sites is less than the number threshold, according to the previously described logistics site screening method, screening out new target logistics sites from multiple logistics sites, the new target logistics site is not the same logistics site as the previously screened target logistics site.

[0111] According to another reference embodiment of the present invention, it is determined whether the coverage of the target logistics site includes multiple logistics sites for screening the target logistics sites, that is, whether the coverage of the target logistics site covers the logistics network composed of multiple logistics sites. For example, the logistics sites that can be reached by the target logistics site via at most two transportation paths are taken as the coverage of the target logistics site. Thus, it is determined whether the coverage of the target logistics site includes all logistics sites for screening the target logistics sites. When the coverage of the target logistics site does not include all logistics sites, new target logistics sites continue to be screened out from the multiple logistics sites until the coverage of all target logistics sites includes multiple logistics sites for screening the target logistics sites.

[0112] For example, Figure 2 As shown, when logistics site 1 is taken as the target logistics site, the preset quantity threshold is determined to be 2. Since the number of target logistics sites is less than the quantity threshold, new target logistics sites are continuously screened out from logistics site 2, logistics site 3, and logistics site 4. As another example, when logistics site 1 is taken as the target logistics site, it is determined that the logistics transportation coverage of logistics site 1 includes logistics site 2 and logistics site 3, but does not include logistics site 4. Therefore, new target logistics sites are continuously screened out from logistics site 2, logistics site 3, and logistics site 4, so that the logistics transportation coverage of the target logistics site includes all logistics sites.

[0113] When the number of target logistics sites is less than the quantity threshold, new target logistics sites are screened out. Multiple target logistics sites can be screened out according to demand, so that the logistics transportation coverage of the target logistics sites covers the entire logistics network, thereby improving the transportation efficiency of the entire logistics network.

[0114] According to another reference embodiment of the present invention, before selecting a new target logistics site from multiple logistics sites, the method further includes: determining the transport capacity attenuation factor of each logistics site relative to the target logistics site, the transport capacity attenuation factor is related to the number of transport paths from the target logistics site to the logistics site that needs to update the logistics transport capacity, the smaller the number of transport paths passed, the larger the transport capacity attenuation factor, the larger the number of transport paths passed, the smaller the transport capacity attenuation factor. According to the transport capacity attenuation factor, the logistics transport capacity of each logistics site is updated.

[0115] For example, the logistics transport capacity update formula of the logistics site is: Among them, u r It means that it takes r transportation paths to reach the target logistics site. u r u r-1 Represents logistics site u r and logistics sites r-1 The logistics transport capacity between r-1 *I <k>< / k> ) is the transport capacity attenuation factor, indicating that the farther the logistics site that needs to update the logistics transport capacity is from the target logistics site, the smaller the transport capacity attenuation factor is. <k>represents the average degree of multiple logistics sites, that is, the average number of first-order logistics sites of multiple logistics sites. Specifically, I <k>< / k> The calculation formula is: Here I <k>< / k> The calculation method of refers to the calculation method of logistics information entropy.

[0116] In accordance with <k>Computation I <k>< / k> In the process, the logistics network composed of multiple logistics sites is regarded as a network with the same degree. <k>The regular network of I <k>< / k> is the logistics transport capacity of any logistics site in the regular network, that is, the logistics information entropy of each logistics site in the logistics network. The initial value of the logistics information entropy of all logistics sites in the logistics network is the same, and the size of the logistics information entropy is related to the average degree. The logistics transport capacity is updated mainly with the average degree. <k>It is related to the association between the target logistics site and other logistics sites. The transport capacity attenuation factor is determined according to the average degree, which reflects the overall information of the logistics network. The logistics transport capacity is updated according to the association and the transport capacity attenuation factor, which reflects the structural information of the logistics network. Before screening out new target logistics sites, the transport capacity of the logistics sites is updated according to the transport capacity attenuation factor, which can avoid the excessive concentration of logistics and transportation coverage of multiple target logistics sites and improve the screening efficiency of target logistics sites.

[0117] Figure 4 Schematic diagram of a transport force attenuation factor according to a reference embodiment of the present invention. Figure 4 As shown, each circle represents a logistics site, the straight lines between the circles represent the transportation paths between the logistics sites, and the numbers inside the circles represent the transportation capacity attenuation factors of the logistics sites. Specifically, the logistics site with a transportation capacity attenuation factor equal to 1 is the screened target logistics site, the transportation capacity attenuation factors of the logistics sites with one transportation path between the target logistics site are all equal to 0.5, and the transportation capacity attenuation factors of the logistics sites with two transportation paths between the target logistics site are all equal to 0.25. The changing trend of the logistics transportation capacity attenuation factor is similar. The farther the distance from the screened target logistics site and the more transportation paths there are, the smaller the transportation capacity attenuation factor is, and the smaller the difference between the updated logistics transportation capacity and the previous logistics transportation capacity is.
