Description

Technical Field

[0001] The present invention relates to the field of intelligent scheduling technology, and in particular to a cold chain logistics intelligent scheduling management method and system. Background Art

[0002] Cold chain logistics refers to a supply chain management system for goods that must be maintained within a certain temperature range during transportation and storage. It is primarily used in the transportation and storage of perishable products such as food, pharmaceuticals, and cosmetics, or products that require specific temperature environments. The key to cold chain logistics is controlling and maintaining the temperature of goods within a specified range to ensure product quality and safety. This requires a combination of various technologies and equipment, including refrigeration equipment, transportation vehicles, temperature monitoring equipment, and information systems.

[0003] Cold chain logistics scheduling refers to the process of rationally arranging and regulating transport vehicles, goods, and delivery routes throughout the cold chain logistics process. It aims to improve transportation efficiency, ensure cargo quality and safety, and optimize resource utilization and cost control.

[0004] In traditional cold chain logistics management, order processing and vehicle scheduling are usually done manually, which is not only inefficient but also prone to errors. In addition, due to the particularity of cold chain logistics, the transportation sequence of goods and the selection of transport vehicles need to take into account multiple factors such as the nature, temperature, and weight of the goods. Therefore, how to intelligently schedule and manage based on these factors is a technical challenge in the field of cold chain logistics. Summary of the Invention

[0005] (1) Technical problems solved

[0006] In response to the technical problems in the background technology, the present invention proposes an intelligent scheduling management method and system for cold chain logistics, which achieves efficient cargo scheduling and distribution and reduces the occurrence of human errors by calculating the priority of the goods to be transported and matching and screening the transport vehicles.

[0007] (2) Technical solution

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] A cold chain logistics intelligent scheduling management method and system, comprising:

[0010] When a new order is required to enter the cold chain logistics center, the relevant information of the goods to be transported in the order is stored in the goods to be transported database; whenever new data is added to the goods to be transported database, the transportation priority of all goods in the goods to be transported database at this time is calculated based on the relevant data stored in the database , according to transportation priority Sort the cargo from high to low;

[0011] Record the status of each transport vehicle. When there is a transport vehicle with the status of "Idle", the maximum load of the transport vehicle is , maximum capacity and the minimum load temperature Calculate the transport vehicle and the sorted Load-bearing matching index of the goods to be transported , Capacity Matching Index and temperature matching index , combining the three matching indices to form the overall matching index , according to the matching index The value of selects the cargo transported by the transport vehicle;

[0012] When the status of a transport vehicle is changed to "assembly", the remaining carrying space and carrying weight of the transport vehicle are used to determine whether the transport vehicle can still transport other goods. If it is determined that other goods can be transported, the destination of the selected goods is marked on the map, and a circle with a radius of The circular range is used as the distribution area; the goods whose destination is in the distribution area are selected from the goods to be transported, and the sub-matching index between the goods and the transport vehicle is further calculated. Determine whether they can be transported together; in rainy and snowy days 300 meters; in non-rainy and snowy weather 500 meters;

[0013] Specifically, a cargo database for transport is established, which records all untransported cargo in the cold chain logistics center, as well as relevant data of these cargoes, such as the value of the cargo, the total amount of cargo, the weight of the cargo, the shelf life of the cargo, the storage temperature requirements of the cargo, the expedited requirements of the cargo, the destination of the cargo, and the storage warehouse information of the cargo;

[0014] Create a transport vehicle information database that stores relevant information about each transport vehicle, including the status, maximum load-bearing capacity, maximum capacity, minimum load-bearing temperature, driver information, and transported cargo information of each transport vehicle.

[0015] Furthermore, the value of each cargo in the cargo library to be transported is The total quantity of each cargo is 、The shelf life of each product is , the required storage temperature for each cargo is 、The expedited index for each cargo is The straight-line distance to the destination of the cargo is ,in Indicates the total number of data in the cargo database to be transported; the expedited index of the cargo Obtained from the expedited requirements of the goods. If the expedited requirement data of a certain goods in the cargo database to be transported is "expedited", the expedited index of the goods If the expedited request data of a certain cargo in the cargo library is "non-expedited", the expedited index of the cargo will be ; Straight-line distance to cargo destination Obtained through third-party mapping services.

[0016] Furthermore, the value of each cargo in the cargo library to be transported , the total amount of each cargo 、The shelf life of each product is , Required storage temperature for each cargo , the expedited index for each shipment and the straight-line distance to the cargo destination Combined separately to form the transportation priority of each cargo , the formula is:

[0017]

[0018] in, 、 、 、 、 The value of each product , the total amount of each cargo , Shelf life of each product , Required storage temperature for each cargo and the straight-line distance to the cargo destination The proportionality coefficient of ; For each product's production date, is the time at that time, and the shelf life of each product is , the production date of each product And the time All are measured in days;

[0019] All goods stored in the cargo warehouse to be transported are sorted according to the calculated transportation priority, and the sorting results are uploaded to the cold chain logistics platform.

[0020] Specifically, each transport vehicle has a status switch button, and each driver also has a status switch button on their cold chain logistics platform account. When a driver presses the status switch button on the transport vehicle or operates the status switch button on the cold chain logistics platform account, a status change signal is triggered. The signal can be transmitted to the cold chain logistics platform via the mobile network. The cold chain logistics platform receives the transmitted status change signal in real time and switches the status on the platform.

[0021] The transport vehicle status includes "transport", "busy", "idle" and "assembling"; the "transport" status indicates that the transport vehicle is currently transporting goods; the "busy" status indicates that the transport vehicle is returning to the logistics center or is being repaired or refueled, and cannot accept new cargo transportation requests at this time; the "idle" status indicates that the transport vehicle is idle at this time and can accept new cargo transportation requests; the "assembling" status indicates that the transport vehicle has been assigned a cargo transportation task, and it is now determined whether the transport vehicle can transport other goods and which goods can be delivered together with the current goods.

[0022] Further, when the transport vehicle information database is detected When a transport vehicle is in the "idle" state, the maximum load-bearing capacity of the transport vehicle is retrieved from the transport vehicle information database. , maximum capacity and the minimum load temperature Data, in turn with the sorted The weight of the goods to be transported , total amount And required storage temperature The data is combined to form the load-bearing matching index of the transport vehicle and the goods to be transported. , Capacity Matching Index and temperature matching index , the formula is:

[0023]

[0024] when =1, it means that the transport vehicle is sufficient to bear the weight of the cargo. =0, it means that the transport vehicle is not strong enough to bear the weight of the cargo; when =1, it means that the capacity of the transport vehicle is sufficient to store the goods. =0, it means that the capacity of the transport vehicle is not enough to store the goods; when =1, indicating that the lowest temperature that the transport vehicle can be set to is lower than the required storage temperature of the goods, that is, it is sufficient to provide a suitable storage environment. =0, indicating that the lowest temperature that the transport vehicle can be set to is not lower than the required storage temperature of the goods, that is, it is not enough to provide a suitable storage environment;

[0025] Furthermore, the load-bearing matching index , Capacity Matching Index and temperature matching index Combined to form an overall matching index , the formula is:

[0026]

[0027] when =1, it means that the transport vehicle matches the goods to be transported, the transportation task of the goods is assigned to the transport vehicle, and the state of the transport vehicle is converted to "assembly"; when =0, it means that the transport vehicle does not match the goods to be transported, and the overall matching index between the transport vehicle and the next goods to be transported is calculated. If the transport vehicle does not match any of the goods to be transported, the status of the transport vehicle is kept as "idle".

[0028] Furthermore, when it is detected that the state of a transport vehicle is converted to "assembly", the remaining carrying space and load-bearing capacity are detected; the remaining carrying space With the remaining load Calculated by the following formula:

[0029]

[0030]

[0031] in, and Respectively represent the maximum carrying space and maximum carrying weight of the transport vehicle; and Indicates the total quantity and weight of the selected goods;

[0032] The remaining carrying space calculated With the remaining load The corresponding carrying space threshold and carrying weight threshold In comparison, if and , it means that the transport vehicle has enough space and load capacity to store other goods; otherwise, the transport vehicle cannot store other goods; and .

[0033] Furthermore, after determining that the transport vehicle has sufficient space and load capacity to store other goods, it is determined whether there are goods that match the transport vehicle, specifically:

[0034] Take the destination data of the first cargo assigned to the transport vehicle from the cargo library and mark it on the map; take this point as the center and draw a circle with a radius of The area inside the circle is used as the delivery area of ​​the transport vehicle and recorded in the transport vehicle information database;

[0035] Mark the destinations of the goods in the cargo library except those that have been selected on the map, filter out the goods to be transported whose destinations are within the delivery area of ​​the transport vehicle, and store them in the data structure in the order of transportation priority;

[0036] For the multiple selected goods to be transported, the matching index needs to be calculated in order of their priority. At this time, the maximum load-bearing capacity, maximum capacity and minimum load temperature data of the transport vehicle have changed. The maximum load space is , the maximum load-bearing weight is , the minimum bearing temperature is ,in The required storage temperature of the first selected cargo, and the corresponding matching index of the selected cargo and the load-bearing capacity of the transport vehicle , Capacity Matching Index and temperature matching index The calculation is as follows:

[0037]

[0038] in, The number of the selected goods in the original priority ranking, 、 、 Respectively The weight, total amount and required storage temperature data of the goods to be transported.

[0039] Furthermore, the above three matching indices are combined to form the secondary matching index of the cargo and the transport vehicle. , the formula is:

[0040]

[0041] when =1, it means that the transport vehicle matches the goods to be transported, that is, the transport vehicle has enough space, load-bearing capacity and minimum temperature to transport the goods, the transport task of the goods is assigned to the transport vehicle, and the remaining carrying space is calculated again With the remaining load Determine whether the transport vehicle can continue to load the goods to be transported; if it can, repeat the above steps to calculate the sub-matching index between the goods and the transport vehicle; if not, the transport vehicle cannot store other goods; when =0, it means that the transport vehicle does not match the goods to be transported, and the sub-matching index between the next goods selected according to the distribution area and the transport vehicle will be calculated. If the transport vehicle does not match any of the selected goods to be transported, the transport vehicle cannot store other goods.

[0042] A cold chain logistics intelligent scheduling and management system, comprising:

[0043] The module for processing goods to be transported: when a new order is required to enter the cold chain logistics center, the relevant information of the goods to be transported in the order is stored in the goods to be transported database; and the transportation priority of each goods to be transported is calculated based on the relevant information of the goods to be transported, and the transportation order of the goods to be transported is sorted according to the transportation priority;

[0044] First cargo allocation module: When a transport vehicle is in the "idle" state, the load-bearing matching index, capacity matching index, and temperature matching index between the transport vehicle and the sorted cargo to be transported are calculated in sequence based on the transport vehicle's maximum load-bearing capacity, maximum capacity, and minimum load-bearing temperature. The three matching indices are combined to form an overall matching index, and the cargo to be transported by the transport vehicle is selected based on the numerical value of the matching index;

[0045] Secondary cargo allocation module: When the transport vehicle is in the "assembly" state, it determines whether the transport vehicle can still transport other cargo based on the remaining carrying space and load capacity of the transport vehicle. It also determines whether the cargo selected by the distribution area can be transported together by calculating the secondary matching index between the cargo and the transport vehicle.

[0046] (3) Beneficial effects

[0050] 3. When a transport vehicle's status changes to "assembly," the remaining carrying space and load capacity of the transport vehicle are used to determine whether the vehicle can still transport other goods. This method can fully utilize the vehicle's carrying capacity, reduce idle time, and improve vehicle utilization.

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0055] refer to Figure 1 The present invention provides a cold chain logistics intelligent scheduling management method, comprising the following steps:

[0056] S1. When a new order is required to enter the cold chain logistics center, the relevant information of the goods to be transported in the order is stored in the goods to be transported database; whenever new data is added to the goods to be transported database, the transportation priority of all goods in the goods to be transported database at this time is calculated based on the relevant data stored in the database. , according to transportation priority Sort the cargo from high to low;

[0057] Establish a cargo database to be transported, which records all untransported cargo in the cold chain logistics center, as well as relevant data of these cargoes, such as the value of the cargo, the total amount of cargo, the weight of the cargo, the shelf life of the cargo, the storage temperature requirements of the cargo, the expedited delivery requirements of the cargo, the destination of the cargo, and the storage warehouse of the cargo;

[0058] The value of the goods can determine the importance of the goods. Goods with higher value may require closer attention and protection, so they may need to be given priority when transporting; the total amount of goods is also an important consideration. If a large amount of goods needs to be transported, transportation may need to be prioritized to reduce the backlog of goods during storage; the shelf life and storage temperature requirements of the goods are factors directly related to the quality and safety of the goods. Goods with a limited shelf life need to be transported as early as possible to ensure that they arrive at the destination in time. For goods that require storage in a specific temperature environment, it is also necessary to give priority to providing suitable transportation conditions; expedited requirements for goods are for those goods that need to be delivered urgently. When considering transportation priority, expedited goods often need to be handled and transported first to meet the urgent needs of customers; finally, the destination of the goods is also an important factor. Long-distance transportation may require longer time and additional arrangements, so it may need to be given priority.

[0059] The value of each cargo in the cargo library to be transported is The total quantity of each cargo is 、The shelf life of each product is , the required storage temperature for each cargo is 、The expedited index for each cargo is The straight-line distance to the destination of the cargo is ,in Indicates the total number of data in the cargo database to be transported; the expedited index of the cargo Obtained from the expedited requirements of the goods. If the expedited requirement data of a certain goods in the cargo database to be transported is "expedited", the expedited index of the goods If the expedited request data of a certain cargo in the cargo library is "non-expedited", the expedited index of the cargo will be ; Straight-line distance to cargo destination Obtained through third-party mapping services.

[0060] The value of each cargo in the cargo library to be transported , the total amount of each cargo 、The shelf life of each product is , Required storage temperature for each cargo , the expedited index for each shipment and the straight-line distance to the cargo destination Combined separately to form the transportation priority of each cargo , the formula is:

[0061]

[0062] in, 、 、 、 、 The value of each product , the total amount of each cargo , Shelf life of each product , Required storage temperature for each cargo and the straight-line distance to the cargo destination The proportionality coefficient of ; For each product's production date, is the time at that time, and the shelf life of each product is , the production date of each product And the time All are in days.

[0063] All goods stored in the cargo warehouse to be transported are sorted according to the calculated transportation priority, and the sorting results are uploaded to the cold chain logistics platform. All staff of the logistics center can view the status of the goods to be transported and the corresponding transportation priority in real time.

[0064] Calculating the transportation priority of cold chain goods to be transported based on the value, total quantity, shelf life, storage temperature requirements, expedited requirements and destination of the goods has many benefits for a cold chain logistics intelligent scheduling management method: it can improve transportation efficiency, reduce transportation risks, meet customer needs, optimize resource allocation, improve decision support, enhance collaboration and communication, optimize inventory management and improve customer service quality.

[0065] S2. Record the status of each transport vehicle. When there is a transport vehicle with the status of "idle", the maximum load-bearing capacity of the transport vehicle is , maximum capacity and the minimum load temperature Calculate the transport vehicle and the sorted Load-bearing matching index of the goods to be transported , Capacity Matching Index and temperature matching index , combining the three matching indices to form the overall matching index , according to the matching index The value of selects the cargo transported by the transport vehicle;

[0066] Each transport vehicle has a status switch button, and each driver also has a status switch button on his account on the cold chain logistics platform; when the driver presses the status switch button on the transport vehicle, or operates the status switch button on the cold chain logistics platform account, a status change signal will be triggered; the signal can be transmitted to the cold chain logistics platform via the mobile network; the cold chain logistics platform receives the transmitted status change signal in real time and switches the status on the platform.

[0067] The transport vehicle status includes "transport", "busy", "idle" and "assembling"; the "transport" status indicates that the transport vehicle is transporting goods at this time; the "busy" status indicates that the transport vehicle is returning to the logistics center or is being repaired or refueled, and cannot accept new cargo transportation requests at this time; the "idle" status indicates that the transport vehicle is idle at this time and can accept new cargo transportation requests at this time; the "assembling" status indicates that the transport vehicle has been assigned a cargo transportation task, and it is now determined whether the transport vehicle can transport other goods and which goods can be delivered together with the current goods.

[0068] The relevant data of each transport vehicle is stored in the transport vehicle information database, which stores the relevant information of each transport vehicle, including the status, maximum load, maximum capacity, minimum load temperature, driver information and transported cargo information of each transport vehicle; the status change of each transport vehicle is monitored in real time, and when the status change of the transport vehicle in the transport vehicle information database is detected, the transport vehicle is automatically When a transport vehicle is in the "idle" state, the maximum load-bearing capacity of the transport vehicle is retrieved from the transport vehicle information database. , maximum capacity and the minimum load temperature Data, in turn with the sorted The weight of the goods to be transported , total amount And required storage temperature The data is combined to form the load-bearing matching index of the transport vehicle and the goods to be transported. , Capacity Matching Index and temperature matching index , the formula is:

[0069]

[0070] when =1, it means that the transport vehicle is sufficient to bear the weight of the cargo. =0, it means that the transport vehicle is not strong enough to bear the weight of the cargo; when =1, it means that the capacity of the transport vehicle is sufficient to store the goods. =0, it means that the capacity of the transport vehicle is not enough to store the goods; when =1, indicating that the lowest temperature that the transport vehicle can be set to is lower than the required storage temperature of the goods, that is, it is sufficient to provide a suitable storage environment. =0, indicating that the lowest temperature that the transport vehicle can be set to is not lower than the required storage temperature of the goods, that is, it is not enough to provide a suitable storage environment;

[0071] Combine the above three matching indices to form the overall matching index , the formula is:

[0072]

[0073] when =1, it means that the transport vehicle matches the goods to be transported, the transportation task of the goods is assigned to the transport vehicle, and the state of the transport vehicle is converted to "assembly"; when =0, it means that the transport vehicle does not match the goods to be transported, and the overall matching index between the transport vehicle and the next goods to be transported is calculated. If the transport vehicle does not match any of the goods to be transported, the status of the transport vehicle is kept as "idle".

[0074] S3. When the status of a transport vehicle is changed to "assembly", the remaining carrying space and carrying weight of the transport vehicle are used to determine whether the transport vehicle can still transport other goods. If it is determined that other goods can be transported, the destination of the selected goods is marked on the map, and a circle with a radius of The circular range is used as the distribution area; the goods whose destination is in the distribution area are selected from the goods to be transported, and the sub-matching index between the goods and the transport vehicle is further calculated. Determine whether they can be transported together; in rainy and snowy days 300 meters; in non-rainy and snowy weather 500 meters;

[0075] In order to optimize transportation efficiency and ensure that the transport vehicle can fully utilize its remaining carrying space and load capacity and load as much cargo as possible, it is necessary to determine whether the transport vehicle can continue to be loaded with the cargo to be transported. Specifically:

[0076] When it is detected that the status of a transport vehicle is converted to "assembly", the remaining carrying space and load-bearing capacity are checked to determine whether the transport vehicle can continue to be loaded with goods; the remaining carrying space With the remaining load Calculated by the following formula:

[0080] The remaining carrying space calculated With the remaining load The corresponding carrying space threshold and carrying weight threshold In comparison, if and , it means that the transport vehicle has enough space and load capacity to store other goods; otherwise, the transport vehicle cannot store other goods; and .

[0081] After determining that the transport vehicle has enough space and load capacity to store other goods, select the goods to be transported together from the goods to be transported. First, you need to determine the delivery area based on the destination of the first selected goods, specifically:

[0082] Take the destination data of the first cargo assigned to the transport vehicle from the cargo library and mark it on the map; take this point as the center and draw a circle with a radius of The area inside the circle is used as the delivery area of ​​the transport vehicle and recorded in the transport vehicle information database;

[0083] After determining the delivery area, you need to filter out all goods whose destinations are within the delivery area, specifically:

[0084] Mark the destinations of the goods in the cargo library except those that have been selected on the map, filter out the goods to be transported whose destinations are within the delivery area of ​​the transport vehicle, and store them in the data structure in the order of transportation priority;

[0085] The transport vehicle matching index is calculated again for the selected goods, specifically:

[0086] For the multiple selected goods to be transported, the matching index needs to be calculated in order of their priority. At this time, the maximum load-bearing capacity, maximum capacity and minimum load temperature data of the transport vehicle have changed. The maximum load space is , the maximum load-bearing weight is , the minimum bearing temperature is ,in The required storage temperature of the first selected cargo, and the corresponding matching index of the selected cargo and the load-bearing capacity of the transport vehicle , Capacity Matching Index and temperature matching index The calculation is as follows:

[0087]

[0088] in, The number of the selected goods in the original priority ranking, 、 、 Respectively The weight, total amount and required storage temperature data of the goods to be transported;

[0089] The above three matching indices are combined to form the secondary matching index between the cargo and the transport vehicle. , the formula is:

[0091] when =1, it means that the transport vehicle matches the goods to be transported, that is, the transport vehicle has enough space, load-bearing capacity and minimum temperature to transport the goods, the transport task of the goods is assigned to the transport vehicle, and the remaining carrying space is calculated again With the remaining load Determine whether the transport vehicle can continue to load the goods to be transported; if so, repeat the above steps to calculate the sub-matching index between the goods and the transport vehicle; if not, the transport vehicle cannot store other goods;

[0092] when =0, it means that the transport vehicle does not match the goods to be transported, and the sub-matching index between the next goods selected according to the distribution area and the transport vehicle will be calculated. If the transport vehicle does not match any of the selected goods to be transported, the transport vehicle cannot store other goods.

[0093] When it is determined that the transport vehicle can no longer store other goods, the relevant information of all matching goods to be transported is sent to the mobile device platform of the corresponding driver.
