Description

Technical Field

[0001] The present invention relates to the field of information technology, and in particular to a method and device for quickly constructing a full-cycle emergency supply chain. Background Art

[0002] At present, emergency supply chains play an important role in disaster prevention, mitigation and relief. Rapid construction and efficient operation of emergency supply chains can ensure timely supply of materials in disaster areas, reduce casualties and improve rescue efficiency. However, disasters of different types and scales will lead to the diversity and volatility of demand for emergency materials, which puts higher requirements on the response speed and adaptability of the supply chain. Therefore, it is crucial to build an emergency supply chain early warning mechanism in the disaster prevention stage. The sources of pre-disaster early warning information are extensive and sufficient. This mechanism can accurately predict potential demand and optimize resource reserve production plans through multi-source data fusion to ensure that the supply chain has sufficient resilience and flexibility when a disaster occurs. In the disaster relief stage, the challenges faced by the supply chain increase sharply, especially when communication equipment is damaged and information is not available. It is crucial to build a robust information flow to promote the operation of material flow. Based on limited basic information, emergency material demand analysis, using data mining technology to quickly obtain and integrate market resources and national reserve supply information, and obtaining real-time traffic information through the commercial map platform interface are key means to ensure post-disaster supply and demand assessment and matching. Therefore, making full use of the advantages of multi-source information before a disaster to ensure that the emergency supply chain can provide effective early warning and, in the event of insufficient post-disaster information, still maintain dynamic updates of information flows through existing basic data and network sharing platforms is a core element to ensure the smooth and efficient operation of the emergency supply chain throughout the disaster response cycle. How to build a full-cycle emergency supply chain is also an issue that needs to be addressed urgently. Summary of the invention

[0055] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field based on this application belong to the scope of protection of the present invention.

[0056] During the disaster relief process, the real-time construction of information flow provides data support for the optimization of material flow, and the efficient operation of material flow is the result of information flow guidance. However, the strategic emergency materials in the national reserve are usually difficult to meet all needs, and social forces are becoming increasingly important in the post-disaster relief process. Although donated materials can alleviate some of the pressure, the lack of a proper management system and overall planning of market resources will still lead to problems such as untimely distribution or shortage of materials. If the market resources of reserve consumables can be fully tapped and combined with national reserve materials to form resource complementarity, it will help improve the efficiency of emergency response. At present, the research content of emergency supply chain mainly includes: (1) Emergency material demand assessment. Based on historical disaster data, scenario analysis and case deduction methods are used to construct disaster scenarios and analyze the material demand under different scenarios. In addition, machine learning methods are also used in demand assessment, but disasters do not occur periodically and cannot provide a large amount of disaster data and cases. (2) Emergency material supply assessment. This part of the research content mainly focuses on the site selection and supply capacity assessment of government reserve warehouses. Most of them fail to consider the impact of demand uncertainty factors, which is likely to limit their application effect in emergency management practice. (3) Supply and demand matching research. Based on the results of emergency material supply and demand assessment, it is necessary to confirm the material dispatch plan and transportation route through supply and demand matching. At the same time, in order to improve the transportation efficiency of materials, emergency material transfer points will also be set up. However, in many studies on the site selection and transportation scheduling of emergency material transfer points, most of the optimization models and algorithms do not consider the acquisition of demand, supply and traffic data, and are often assumed to be fixed parameters or random distributions. A review of existing emergency supply chain research found that although there are endless optimization models for emergency supply chain supply and demand assessment and matching, there are still a series of scientific problems that need to be solved: (1) The data required by many existing models cannot be obtained in real time, and they are assumed or randomly set, which cannot be directly used in practice. A large number of theories and practices cannot be matched, forming a gap that hinders the full flow of information and material flows in the emergency supply chain. (2) National reserve materials are often strategic materials. Post-disaster emergency materials, especially various consumable materials, cannot meet the demand at all. Although the importance of social forces in the emergency process has been widely recognized, how to make full use of and integrate market resources has become the key.

[0057] In order to build a full-cycle emergency supply chain, the first aspect of the embodiment of the present application first provides a method for quickly building a full-cycle emergency supply chain, see Figure 1 , Figure 1 A flowchart of a method for rapidly constructing a full-cycle emergency supply chain provided in an embodiment of the present application, the method comprising:

[0058] Step S11, obtaining disaster information;

[0059] Step S12, determining material demand side information according to the disaster information and a preset demand coefficient, wherein the material demand side information includes the location of the material demand side and the quantity of materials required;

[0060] Step S13, determining a first buffer zone according to the location information of the material demand end;

[0061] Step S14, identifying the market material information and the reserve material information of the first buffer zone, and determining the first material supply end information, wherein the first material supply end information includes the quantity of materials supplied in the first buffer zone;

[0062] Step S15, when the quantity of materials supplied in the first buffer zone does not meet the quantity of materials required, determining a second buffer zone;

[0063] Step S16, identifying the market material information and the reserve material information of the second buffer zone, and determining the second material supply end information, wherein the second material supply end information includes the material supply end location and the quantity of the supplied materials in the second buffer zone;

[0064] Step S17, when the quantity of materials supplied in the second buffer zone meets the quantity of materials required, determine the transportation route of the materials according to the location of the material demand end and the location of the material supply end in the second buffer zone.

[0065] Corresponding to the above step S11, disaster information can be obtained by obtaining and integrating disaster information in real time based on authoritative channels such as government reports or social media to obtain disaster information. Specific disaster information may include the type, intensity, impact range and duration of the disaster, the predicted number of injured, the actual number of injured, the number of people relocated and resettled (or the number of shelters) and the number of days affected by the disaster.

[0066] Corresponding to the above step S12, the material demand side information includes the location of the material demand side and the quantity of materials required. The material demand side information is determined based on the disaster information and the preset demand coefficient. A material demand coefficient model can be established based on historical earthquake data and expert opinions to define the demand coefficient standard for each relief material (such as food, drinking water, medicine, tents, etc.). According to the number of people affected, the number of days affected, material demand factors and economic factors, the demand for each type of material is evaluated in combination with the material demand coefficient model. For consumables, the evaluation is based on the demand per person per day. For non-consumables, a demand assessment is required based on the number of shelters. In an example, the preset demand coefficient can be the number of materials corresponding to the number of people. For example, if the quota per person per day is one bottle of water, the preset demand coefficient for water can be set to 3. For an example of determining the material demand side information, please refer to Figure 2, obtain government reports and social media information, then extract information, identify the number of people to be relocated and resettled, the number of injured people, and the number of shelters on the demand side of materials, and then conduct a demand assessment, and determine real-time demand information through empirical estimation methods and demand coefficient models.

[0067] Corresponding to the above step S13, the first buffer zone is determined according to the location information of the material demand side. The buffer zone can be delineated based on the disaster scope information, and the disaster-stricken area and the buffer zone can be divided into multiple geographical area units (such as administrative districts, kilometer grids, etc.) to facilitate the same spatial scale unit as the demand assessment. In one example, the buffer zone is determined according to the spatial scale, such as determining 10 kilometers around the disaster area as the first buffer zone. In another example, the buffer zone can be determined according to the administrative division, such as determining the adjacent counties or cities around the administrative district where the disaster area is located as the buffer zone.

[0068] Corresponding to the above-mentioned step S14, wherein the first material supply-end information includes the quantity of materials supplied in the first buffer zone. When identifying the market material information and reserve warehouse material information of the first buffer zone and determining the first material supply-end information, both the materials in the reserve warehouse and the materials on the market can be identified. Based on the network sharing platform, the type coding, category and geographic location information of market resources can be mined. Through the category to which the market resources belong, the scale of such emergency material supply sources can be intuitively and scientifically judged, and the supply evaluation of potential emergency material supply sources can be realized. For example, medical supplies are usually distributed in medical and health care service places such as general hospitals and specialized hospitals. Their type coding and category attribute values ​​can be listed as shown in Table 1.

[0069] Table 1 Attribute categories of medical care services

[0070] In an example, identifying the material supply side information can be seen in Figure 3 , conduct data mining and information extraction through the data sharing platform, identify national reserves, such as central reserves and local reserves, and market resources, such as raw material suppliers and original parts suppliers of upstream enterprises, manufacturers and assemblers of midstream enterprises, and distributors, wholesalers and retailers of downstream enterprises, and then conduct data cleaning and supply source analysis for market resources, integrate resources in national reserves, such as data comparison and keyword matching, and determine real-time supply information.

[0071] Corresponding to the above step S15, when the quantity of materials supplied in the first buffer zone does not meet the quantity of materials required, when determining the second buffer zone, the second buffer zone may include the first buffer zone. In one example, the buffer zone is determined according to the spatial scale, such as determining 10 kilometers around the disaster area as the first buffer zone, and determining 20 kilometers around the disaster area as the second buffer zone. In another example, the buffer zone is determined according to the administrative division, and new administrative districts can be added on the basis of the first buffer zone to obtain the second buffer zone. In a possible implementation, after identifying the market material information and reserve material information of the first buffer zone and determining the first material supply end information, the method further includes: when the quantity of materials supplied in the first buffer zone meets the quantity of materials required, determining the transportation route of the materials according to the location of the material demand end and the location of the material supply end in the first buffer zone.

[0072] Corresponding to the above step S16, the second material supply end information includes the material supply end position and the quantity of materials supplied in the second buffer. The market material information and the reserve material information of the second buffer are identified, and the second material supply end information is determined, referring to step S14, and both the materials in the reserve and the materials on the market can be identified.

[0073] Corresponding to the above step S17, when the quantity of materials supplied in the second buffer zone meets the quantity of materials required, when determining the transportation route of materials according to the position of the material demand end and the position of the material supply end in the second buffer zone, it is possible to first determine whether the quantity of materials supplied in the second buffer zone meets the quantity of materials required, and determine the transportation route of materials when the quantity of materials supplied in the second buffer zone meets the quantity of materials required. When determining the transportation route of materials, commercial navigation software can be used for calculation. In addition, the navigation software can update the transportation route in real time according to the road conditions. For example, the path planning of the commercial map software is called to obtain basic traffic network information, and the traffic conditions are updated every five minutes. At the same time, avoiding congestion and the shortest travel time are set as the driving strategy to promote the supply and demand matching part. In a possible implementation, after identifying the market material information and the reserve material information of the second buffer zone and determining the second material supply end information, the method further includes: determining a third buffer zone when the quantity of materials supplied in the second buffer zone does not meet the quantity of materials required. Then determine whether the materials in the third buffer zone meet the required quantity of materials. If so, determine the transportation route of the materials based on the third buffer zone. If not, define a larger buffer zone until the materials in the buffer zone meet the required quantity of materials and determine the transportation route of the materials.

[0074] It can be seen that through the method of the embodiment of the present application, the material demand side information can be determined according to the disaster information, and thus the first buffer zone can be determined according to the material demand side information. When the materials in the first buffer zone cannot meet the demand, the second buffer zone is re-determined, and when the materials in the second buffer zone meet the demand, the transportation route of the materials is determined according to the location of the material demand side and the location of the material supply side in the second buffer zone, thereby realizing the rapid construction of a full-cycle emergency supply chain.

[0075] In one possible implementation, see Figure 4 , the determining of the material transportation route according to the location of the material demand end and the location of the material supply end in the second buffer zone includes:

[0076] Step S41, when there are multiple material supply end locations in the second buffer area that meet the material quantity required, identify the route between each material supply end location that meets the material demand end location to obtain multiple first routes;

[0077] Step S42, identifying the travel time corresponding to each first route according to the navigation map, and determining the first route with the shortest travel time as the transportation route for the materials.

[0078] Specifically, we can establish the target conditions for material supply and demand balance, set the constraints for completing emergency material dispatch in the shortest time, and propose a material dispatch plan. In an example, the emergency material supply and demand matching algorithm is as follows:

[0079] enter: , , , , ,

[0080] Output: , ,

[0081] Step 1. for do

[0082] for do

[0095] end for

[0096] Step 3. if then

[0097]

[0098]

[0099] end if

[0100] end

[0101] In a possible implementation manner, the disaster information includes the type of disaster, the number of people affected and the location of the disaster, see Figure 5 , the determining of material demand side information according to the disaster information and the preset demand coefficient includes:

[0102] Step S51, determining the location of the material demand end according to the disaster-affected location;

[0103] Step S52, determining the type of materials required according to the type of disaster; and determining the quantity of materials required according to a preset demand coefficient corresponding to the number of disaster victims and the type of materials required.

[0104] In actual use, when the location of the material demand end is determined according to the disaster-stricken location, the demand end can be either a resettlement point corresponding to the disaster-stricken location or a hospital in the disaster-stricken area. When the type of materials required is determined according to the type of disaster, the required daily necessities, medical supplies, etc. can be determined, such as assault boats for flood disasters, medical supplies for fires, etc. The preset demand coefficients corresponding to different types of materials can be set based on experience. When determining the quantity of materials required based on the preset demand coefficients corresponding to the number of people affected and the type of materials required, the product of the number of people affected and the preset demand coefficient can be calculated to obtain the required quantity of materials.

[0105] In order to illustrate the solution of the embodiment of the present application, the following is described in conjunction with specific embodiments. Figure 6 , including the following steps:

[0106] S1. Obtain and integrate disaster information in real time based on authoritative channels such as government reports or social media to determine the demand side of materials;

[0107] S2. Complete the emergency relief material demand assessment by combining the empirical estimation method and demand coefficient model;

[0108] S3. Fully explore the market resources within the designated buffer zone of the disaster area through the network sharing platform, use the fuzzy word matching method to screen out a list of various material supply sources suitable for post-disaster relief, and conduct data cleaning and supply source analysis;

[0109] S4. Build an upstream, midstream and downstream industrial chain mechanism to integrate the production and supply capabilities of upstream, midstream and downstream enterprises;

[0110] S5. Integrate market resources and national reserve materials through data comparison and keyword matching, and use the regional accumulation method to evaluate the supply capacity of government reserves, market resources and industrial chains in various geographical units;

[0111] S6. Introduce commercial map navigation platform interfaces to solve the problem of missing real-time path information, obtain traffic conditions, directly read the road network in the disaster area, and generate the shortest path and travel time;

[0112] S7. Use the emergency material shortage and supply priority evaluation method based on TOPSIS (Technique for Order Preference by Similarity to an Ideal Solution, a ranking method) to complete supply and demand matching, and select appropriate emergency material supply sources to ensure high-reliability redundant matching under uncertain supply and demand conditions.

[0113] For details, see Figure 7, information flow can include: real-time demand information, real-time traffic information and real-time supply information to determine the information flow; then match supply and demand, evaluate the urgency of material demand through TOPSIS analysis method, set the objective function: complete the distribution of materials in the shortest time, and constraints: limited resources constraints; then determine the emergency material dispatch plan; finally determine the material flow, including according to the material demand end, material transportation end and material supply end.

[0115] Information acquisition module 801, used to acquire disaster information;

[0120] The second material determination module 806 is used to identify the market material information and the reserve material information of the second buffer zone, and determine the second material supply end information, wherein the second material supply end information includes the material supply end location and the quantity of the supplied materials in the second buffer zone;

[0121] The route determination module 807 is used to determine the transportation route of the materials according to the location of the material demand end and the location of the material supply end in the second buffer zone when the quantity of materials supplied in the second buffer zone meets the quantity of materials required.

[0122] In a possible implementation, the route determination module is specifically used to, when there are multiple material supply end locations that meet the demand for the quantity of materials in the second buffer zone, identify the route between each material supply end location that meets the demand and the material demand end location to obtain multiple first routes; based on the navigation map, identify the travel time corresponding to each first route, and determine the first route with the shortest corresponding travel time as the transportation route for the materials.

[0127] In a possible implementation, the device further includes:
