Description

Technical Field

[0001] The present invention relates to the technical field of logistics management, and particularly to a method, system and medium for full-process tracking management of cold chain logistics. Background Art

[0002] Cold chain logistics refers to the process of transporting, storing and distributing goods, in which temperature, humidity and other factors need to be controlled throughout the process to ensure that the quality of the goods is not affected by the external environment. Especially for temperature- and time-sensitive goods such as food and medicine. Traditional cold chain logistics management faces the problems of information islands and inability to transmit data in real time, resulting in the inability to grasp the status of cold chain goods in real time, affecting the quality and safety of the goods. Especially during transportation, factors such as the transition and transfer of different cycle nodes often become important links affecting the quality of cold chain logistics. Problems such as temperature fluctuations, time delays and equipment failures in these links will reduce the reliability of cold chain logistics and bring potential risks of cargo damage to the goods. Existing cold chain logistics management systems usually lack comprehensive consideration and full-process tracking of these influencing factors, resulting in the inability to effectively respond to various emergencies generated during the logistics process. Therefore, there is an urgent need to establish an intelligent tracking management system that runs through the entire logistics cycle, and through data fusion and intelligent analysis technologies, achieve full-process and refined control of temperature-sensitive goods, ensuring that the cold chain does not break and the quality is traceable.

Specific implementation manners

[0013] The above technical solutions will be described in detail below in conjunction with the drawings in the specification and specific implementation manners to better understand the above technical solutions. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments of the present invention. It should be understood that the present invention is not limited to the example embodiments only used to explain the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention. In addition, it should be noted that for the convenience of description, only parts related to the present invention are shown in the drawings rather than all.

[0014] Example 1, as Figure 1 This is a schematic flowchart of the method for full-process tracking and management of the cold chain logistics of the present invention. Among them, the method for full-process tracking and management of the cold chain logistics includes:

[0015] Analyze the influence relationship of the cold chain items in the entire logistics cycle, obtain the cold chain correlation parameters of each cycle node, and construct a full-process data acquisition architecture, including cycle nodes, correlation parameters, and their data acquisition interfaces.

[0016] Specifically, the influence relationship of the cold chain items in the entire logistics cycle refers to the parameters that have a greater impact on each link during the entire process from the start of transportation of the cold chain items to the destination. For example, the temperature, thermal resistance, etc. during the production pre-cooling cycle. For each cycle node of the cold chain items, such as production, warehousing, transportation, transfer, etc., the influence parameters of the environmental temperature will be analyzed to determine the cold chain correlation parameters of each cycle node. These parameters will have a greater impact on the temperature of the cold chain items, thereby affecting the quality of the cold chain items. In order to effectively monitor the cold chain items, a comprehensive data acquisition architecture needs to be constructed. This architecture needs to cover all cycle nodes and be able to capture various correlation parameters (such as temperature, humidity, etc.) related to the status of the cold chain items through the data acquisition interface. Among them, the data acquisition interface can be connected to sensors, logistics management systems, equipment on transportation vehicles, etc. to ensure that the environmental conditions of the cold chain items are monitored and recorded in real time at each node of the cold chain logistics, providing an important basis for subsequent cold chain logistics management and optimization decisions.

[0017] In some embodiments, analyzing the impact relationship of the entire cold chain logistics cycle on cold chain items includes:

[0018] From the starting stage of cold chain item production to the completion stage of logistics distribution, dividing cycle nodes according to the environmental change nodes of cold chain items to obtain full-cycle nodes; analyzing the environmental temperature impact parameters of the full-cycle nodes to determine the temperature impact relationship on cold chain items, and extracting cold chain correlation parameters for each cycle node from the temperature impact relationship.

[0019] Specifically, in the process of cold chain logistics, from the starting stage of cold chain item production to the completion stage of logistics distribution, the entire cold chain logistics process will be divided into multiple cycle nodes according to the environmental change nodes of cold chain items (determined according to domain knowledge and business requirements) to form full-cycle nodes. These nodes represent the environmental changes experienced by cold chain items at different transportation stages, usually including production pre-cooling, warehousing, trunk transportation, transfer loading and unloading, and last-mile delivery. Each node has different environmental conditions and cold chain factors affecting the items. Subsequently, analyze the environmental temperature impact parameters of these cycle nodes, analyze the temperature changes in different nodes through on-site simulation and domain expert decision-making, find out the environmental parameters that will affect the temperature of cold chain items, and extract these parameters as the cold chain correlation parameters for each cycle node. These parameters reflect the changes in the cold chain state of items under specific environmental conditions. For example, the initial temperature, pre-cooling rate, and packaging thermal resistance value in the production pre-cooling stage will all affect the temperature of cold chain items, and these parameters can be obtained through an infrared thermal imager connected to the data acquisition interface; the temperature and humidity gradient, the temperature inside the stack, and the door opening frequency in the warehousing stage will all affect the temperature of cold chain items, and these parameters can be obtained through a multi-point temperature and humidity sensor connected to the data acquisition interface; the temperature uniformity in the trunk transportation stage, the vibration intensity, and the number of times the door is opened will all affect the temperature of cold chain items, and these parameters can be obtained through an in-vehicle IoT terminal and a thermometer connected to the data acquisition interface; the exposure time, environmental temperature difference, and refrigeration efficiency of the loading and unloading equipment in the transfer loading and unloading will all affect the temperature of cold chain items, and these parameters can be obtained through a handheld temperature recorder and a log connected to the data acquisition interface; the decay curve of the temperature in the thermal insulation box and the customer signature delay in the last-mile delivery stage will all affect the temperature of cold chain items, and these parameters can be obtained through a Bluetooth temperature tag connected to the data acquisition interface. Through the above process, it is possible to comprehensively understand the temperature impact of each cycle node on cold chain items and extract key cold chain parameters from them, providing data support and decision-making basis for subsequent cold chain logistics management and optimization.

[0020] Obtain the item information of cold chain logistics, analyze the cold chain logistics constraint conditions of the item information, and determine the cold chain constraint information of the item, including the constraint relationship between temperature and time.

[0021] Specifically, in cold chain logistics, item information of cold chain items is obtained, such as the type, characteristics, packaging method, storage requirements, cargo damage type, etc. of cold chain items. This information helps to understand the environmental requirements of cold chain items and the requirements that need to be complied with during transportation. Once the item information of cold chain items is obtained, an analysis of cold chain logistics constraint conditions will be carried out on this information. The core of this analysis is to determine the maximum temperature and maximum time that cold chain items can withstand throughout the logistics process according to the cargo damage type of cold chain items, and based on this, determine the item cold chain constraint information for each cold chain item, that is, the constraint relationship between temperature and time. Within this constraint information, cold chain items can maintain the best quality and safety. If this constraint information is exceeded, the quality of cold chain items may be affected, and even spoilage or failure may occur. Through the analysis of this step, the temperature and time limits of different items can be clarified, providing a scientific basis for subsequent cold chain management strategies and control means to ensure the safety and quality of cold chain items throughout the logistics process.

[0022] In some embodiments, an analysis of cold chain logistics constraint conditions is carried out on the item information to determine the item cold chain constraint information, including:

[0023] Parsing and classifying according to the cargo damage type of the item information to obtain the cold chain item cargo damage categories, including failure types and spoilage types; obtaining the standard temperature, temperature tolerance, and maximum exposure time of the failure type, fitting the failure relationship according to the temperature tolerance and maximum exposure time to determine the item cold chain constraint information; obtaining the respiratory heat load, spoilage temperature, and its time threshold of the spoilage type, fitting the spoilage relationship according to the respiratory heat load, spoilage temperature, and time threshold to determine the item cold chain constraint information.

[0024] Specifically, in cold chain logistics, the types of cargo damage of cold chain items directly affect the transportation and storage requirements of the items. Therefore, the types of cargo damage of cold chain items are extracted from the item information of cold chain items and classified according to the types of cargo damage to obtain the cold chain item cargo damage categories, including failure types and spoilage types. Among them, the failure type is usually related to the loss of item function or property change caused by too high or too low temperature. For example, chemical substances such as drugs and vaccines may undergo chemical reactions at high or low temperatures, thus losing their efficacy. The spoilage type is mainly related to the spoilage and deterioration of biological items (such as food) due to factors such as temperature and humidity. For cold chain items of the failure type, refer to the product data of the cold chain item to obtain the standard temperature, temperature tolerance, and maximum exposure time of the cold chain item. Among them, the standard temperature is the normal temperature range of the cold chain item. Exceeding this temperature range may cause the item to fail. For example, some drugs are stored best within the range of 2-8°C. Exceeding or being lower than this temperature will weaken or completely lose the efficacy. The temperature tolerance refers to the temperature change range that the item can tolerate. For example, some drugs may allow a fluctuation of up to 10°C for a short time, but will fail if exposed to this temperature for a long time. The maximum exposure time refers to the maximum time that the item can be exposed to the external environment. Exceeding this time will cause failure even if the temperature change is within the allowable range. After obtaining the standard temperature, temperature tolerance, and maximum exposure time, these data will be fitted, that is, these data will be fitted into a space (the x-axis represents the standard temperature, the y-axis represents the temperature tolerance, and the z-axis represents the maximum exposure time), and this space will be used as the item cold chain constraint information of cold chain items of the failure type. For cold chain items of the spoilage type, obtain the respiratory heat load, spoilage temperature, and spoilage time threshold in the same way. Among them, the respiratory heat load refers to the heat generated by the item during storage due to biological activities (such as respiration). Usually, biological items (such as fruits and vegetables) will accelerate their respiration at inappropriate temperatures, thus causing the temperature to rise, which will lead to spoilage. The spoilage temperature is the critical temperature at which the item begins to spoil. When the item temperature is higher than this temperature, the spoilage process will accelerate. The spoilage time threshold is the maximum allowable time for the item after the temperature exceeds the spoilage temperature. Exceeding this time, the spoilage process will develop rapidly, and the risk of item spoilage will increase. By fitting the respiratory heat load, spoilage temperature, and spoilage time threshold into a space, the item cold chain constraint information of cold chain items of the spoilage type is obtained. Through these item cold chain constraint information, the specific requirements of each cold chain item can be understood, which helps to take effective control measures during cold chain transportation and storage to ensure that the item maintains the best state throughout the cold chain logistics link and avoid quality loss caused by environmental changes.

[0025] In some embodiments, after determining the item cold chain constraint information, it further includes:

[0026] Construct a cargo damage evaluation model based on the failure relationship or spoilage relationship; quantify the cargo damage through the cargo damage evaluation model to obtain a cargo damage evaluation coefficient.

[0027] Specifically, in order to quantify the cargo damage risk caused by factors such as temperature changes and exposure time during the transportation and storage of cold-chain items, a cargo damage evaluation model will be constructed according to the failure relationship or spoilage relationship. Taking the failure relationship as an example, sample cumulative temperature (composed of sample temperatures), sample cumulative time, and sample cargo damage evaluation coefficients are collected. These sample data are divided to obtain training data and validation data. Subsequently, an initial cargo damage evaluation model is constructed using a long short-term memory network (LSTM), including an input layer, an LSTM layer, a fully connected layer, and an output layer. Then, the weights and biases of the initial cargo damage evaluation model are initialized using random numbers and other methods, and the training data is input into the initialized initial cargo damage evaluation model for forward propagation. Through layer-by-layer transmission, the predicted cargo damage evaluation coefficient is calculated. After that, the mean squared error (MSE) loss function is used to calculate the loss value between the prediction result and the sample data, and the gradient of the loss with respect to the weights of each layer is calculated layer by layer through backpropagation. Then, the Adam optimizer is used to optimize the model parameters and adjust the weights to minimize the value of the loss function. The above process is repeated until the maximum number of iterations is reached. After the training is completed, the validation data is used to test the model performance, and indicators such as the accuracy of the model in calculating the cargo damage evaluation coefficient and the loss value are evaluated. If these indicators meet the preset standards, the current initial cargo damage evaluation model is output as the final cargo damage evaluation model. Otherwise, hyperparameters such as the learning rate and the number of training batches are adjusted to further improve the prediction ability of the cargo damage evaluation model. For the spoilage relationship, the sample cumulative temperature (composed of sample respiratory heat and sample temperature), sample time, and sample cargo damage evaluation coefficient are used as training data, and a cargo damage evaluation model of the spoilage type is constructed through the same steps as above. After obtaining the cargo damage evaluation model, the actually collected environmental data is input into the model, and the model analyzes these data according to the learned mapping relationship to quantify a cargo damage evaluation coefficient under the current environmental conditions, thereby helping to quickly evaluate the risks in the cold-chain process, formulate corresponding countermeasures, and effectively ensure the quality and safety of cold-chain items during transportation.

[0028] Through the above-mentioned full-process data acquisition architecture, perform the full-process time-series cumulative operation on the associated parameter acquisition data to obtain the temperature-time data mapping relationship.

[0029] In one embodiment, during the cold chain logistics process, cold chain items will experience various environmental changes at different transportation and storage stages. To ensure that cold chain items are always in the best storage conditions, a full-process data acquisition architecture is activated to monitor these environmental factors. The full-process data acquisition architecture collects environmental parameters through multiple data acquisition interfaces to obtain associated parameter acquisition data, such as the initial temperature of the pre-cooling node, the temperature and humidity gradient of the cold storage in the warehousing node, and the temperature uniformity of the carriage in the trunk transportation node. Subsequently, time-series cumulative operations are performed on these collected temperature data. The core of this process is to aggregate the temperature data at different time points according to the cumulative time granularity to form an overall record of the temperature changing over time, that is, the temperature-time data mapping relationship. In summary, this cumulative method helps to evaluate the risks in the cold chain logistics process and the overall state of cold chain items, assisting in making reasonable adjustments and optimizations to ensure that the quality of cold chain items is not lost.

[0030] In some embodiments, through the full-process data acquisition architecture, full-process time-series cumulative operations are performed on the associated parameter acquisition data to obtain the temperature-time data mapping relationship, including:

[0031] Through the full-process data acquisition architecture, the monitoring data of each cycle node is obtained, and the monitoring data is projected according to the cycle nodes to establish a time-series monitoring chain; based on the time-series monitoring chain, cumulative operations of the temperature measurement quantity and the time measurement quantity are performed, and cumulative quantity mapping is performed according to the corresponding relationship between the temperature measurement quantity and the time measurement quantity to obtain the temperature-time data mapping relationship.

[0032] Specifically, at each node in the cold chain logistics (such as production precooling, warehousing, transportation, etc.), environmental data such as temperature and humidity are monitored in real time through the whole-process data acquisition architecture. The data at each cycle node will be collected according to different monitoring interfaces. For example, in the production precooling stage, temperature data may be obtained through an infrared thermal imager, and in the transportation stage, the temperature information of the carriage is obtained through an in-vehicle IoT terminal. These monitoring data not only include temperature, but may also include other factors related to the quality of the cold chain such as humidity and vibration. These data will be collected and recorded in real time to provide a basis for subsequent analysis. Subsequently, the data at each cycle node will be projected into the time series chain of the cycle node in chronological order to form a time series monitoring chain. The purpose of the projection process is to calibrate the monitoring data of each node according to its time point and cycle, ensuring that the data of each node in the entire cold chain process can be correctly connected in time series. Exemplarily, the temperature data in the warehousing stage may be collected at different time points, such as [(8:00AM, 4℃), (9:00AM, 4.2℃), (10:00AM, 4.1℃), (11:00AM, 4.3℃)], and the same is true for the temperature data in the transportation stage, such as [(12:00PM, 3.8℃), (12:30PM, 4.0℃), (1:00PM, 4.2℃), (1:30PM, 4.1℃)]. All these data will be organized into a time series monitoring chain, such as [(8:00AM, 4℃), (9:00AM, 4.2℃), (10:00AM, 4.1℃), (11:00AM, 4.3℃), (12:00PM, 3.8℃), (12:30PM, 4.0℃), (1:00PM, 4.2℃), (1:30PM, 4.1℃)], reflecting the change of temperature in the whole cold chain logistics process. After that, the temperature data and its corresponding time data are accumulated according to the cumulative time granularity to obtain the time cumulative amount, and then the time cumulative amount is arranged in time series to form a mapping relationship between temperature and time. This mapping relationship can help analyze the overall quality status of cold chain items under different temperature and time combinations, so as to timely discover potential risks and take measures for optimization and adjustment to ensure that the items are in the best state during transportation and storage.

[0033] In some embodiments, temperature monitoring quantity and time monitoring quantity cumulative operations are performed based on the time series monitoring chain, including:

[0034] According to the failure type, spoilage type and their cargo damage sensitivity, set the cumulative time granularity; extract the temperature monitoring quantity from the time series monitoring chain according to the cumulative time granularity, perform time series aggregation on the extracted time series temperature monitoring values to obtain the temperature cumulative amount and its corresponding time granularity, and perform cumulative time aggregation based on the time granularity to obtain the time cumulative amount.

[0035] Specifically, according to the failure type, spoilage type and cargo damage sensitivity of cold-chain items, setting the cumulative time granularity is to more accurately evaluate the impact of temperature changes on the quality of items during transportation. For temperature-sensitive items (such as drugs, vaccines, etc.), since these items are very sensitive to temperature fluctuations and any small temperature change may affect their efficacy, a finer time granularity, such as a 1-minute granularity, is required to monitor their temperature in real time. For some storable items (such as certain foods), these items are relatively less sensitive to temperature fluctuations, so a coarser time granularity, such as 5 minutes or 10 minutes, can be used to reduce the computational amount and maintain the effectiveness of monitoring. Therefore, according to the cargo damage category and cargo damage sensitivity of each item, combined with industry standards and historical experience, a suitable granularity is selected as the cumulative time granularity. Subsequently, according to the set cumulative time granularity, the temperature data corresponding to the corresponding time is extracted from the time series monitoring chain. For example, when the cumulative time granularity is 1 minute, the temperature data per minute is extracted from the time series monitoring chain and recorded. After that, for the extracted temperature data, these data are subjected to time series aggregation, that is, the temperature data recorded according to the time granularity are added up to obtain the temperature cumulative amount for that time period. After aggregating the temperature data, time cumulative aggregation is also performed on the time data, that is, the times corresponding to the temperature data are added up to obtain the time cumulative amount. Then, the temperature cumulative amount and the time cumulative amount are mapped, that is, the time cumulative amount and the temperature cumulative amount at each moment are corresponded to form a temperature-time data mapping relationship, providing data support for cold-chain management to ensure that cold-chain items always remain in the optimal temperature control environment throughout the transportation process.

[0036] According to the cold-chain constraint information of the item, a cold-chain constraint evaluation is performed on the temperature-time data mapping relationship to obtain cold-chain evaluation information.

[0037] Specifically, after obtaining the temperature-time data mapping relationship, the temperature accumulation, time accumulation and their corresponding relationships are extracted from the temperature-time data mapping relationship. Among them, for the failure type, the corresponding relationship indicates the moment when the accumulated time is the exposure time and the temperature change at each moment; for the spoilage type, the corresponding relationship indicates the moment when the accumulated heat is the respiratory heat. Subsequently, the extracted data is compared with the corresponding cold chain constraint information of the item to determine whether the temperature accumulation and time accumulation exceed the tolerable limit of the item, such as whether the temperature exceeds the allowable temperature control range of the item and whether the exposure time exceeds the maximum exposure time. If both are within the range of the cold chain constraint information of the item, it indicates that the cold chain transportation risk is relatively small at this time, and a default loss evaluation coefficient, such as 0.1 or 0.2, will be set and used as the cold chain evaluation information. Otherwise, the loss evaluation model will be used for quantification to obtain the loss evaluation coefficient in the current environment as the cold chain evaluation information. If the cold chain evaluation information shows a high loss coefficient, it means that the temperature fluctuates too much during transportation or storage, and the quality of the item may have been damaged; if the loss coefficient is low, it indicates that the cold chain management is relatively compliant and the quality of the item is within an acceptable range. Generally speaking, this process helps to evaluate the quality risk in the cold chain process, provides data support for decision-making, and ensures the quality of cold chain items during transportation.

[0038] In some embodiments, according to the cold chain constraint information of the item, a cold chain constraint evaluation is performed on the temperature-time data mapping relationship to obtain cold chain evaluation information, including:

[0039] According to the temperature-time data mapping relationship, the temperature accumulation, time accumulation and their corresponding relationships are extracted; the loss evaluation model is used to quantify the temperature accumulation, time accumulation and their corresponding relationships to obtain a loss evaluation coefficient; the loss evaluation coefficient is used as the cold chain evaluation information.

[0040] Specifically, the temperature accumulation, time accumulation and their corresponding relationships are extracted from the temperature-time data mapping relationship, and the cold chain constraint information of the item is used for judgment. When the requirements of the cold chain constraint information of the item are not met, the temperature accumulation and time accumulation are input into the loss evaluation model for quantification, so as to convert the cumulative effect of temperature and time into a loss evaluation coefficient. Finally, this loss evaluation coefficient is used as the cold chain evaluation information to help evaluate the risk in the entire cold chain process to ensure that the quality of cold chain items is not damaged.

[0041] According to the cold chain evaluation information, the cold chain logistics parameters of the cycle node are optimized to generate a logistics management strategy, including temperature control, transfer control of the cycle node, and optimization control of the logistics path.

[0042] Specifically, after obtaining the cold chain evaluation information, the cycle nodes of the cold chain logistics will be optimized according to the cold chain evaluation information. Specifically, first, based on the evaluation results of each cycle node reflected in the cold chain evaluation information, compare its timing relationship with that of the full cycle nodes, and extract the subsequent timing cycles that need to be optimized. These subsequent optimized timing cycles are usually the nodes with longer exposure time or larger temperature fluctuations during the cold chain process, that is, the cycle nodes where the cargo damage evaluation coefficient is greater than or equal to the cargo damage threshold. After determining the timing cycles that need to be optimized, obtain the optimizable parameters of these cycles. These parameters may include temperature control parameters, transfer control parameters for cycle nodes, or logistics path adjustment parameters, etc. Through the analysis of these parameters, construct an optimization evaluation function, and calculate the margin for the target damage assessment threshold of the cold chain items. The purpose of this margin calculation is to measure how much risk the cold chain items can still bear under the existing conditions without affecting the final quality standard. Finally, based on the optimization evaluation function, search for the margin to find the optimization parameters that can meet the margin conditions and minimize the cargo damage evaluation coefficient. These optimal parameters will be used as the final logistics management strategy, including specific adjustments to temperature control, transportation path optimization, and management control during the transfer process. Through such a process, it is possible to ensure that the temperature of the items in the cold chain logistics remains in the best state, while minimizing the quality loss during transportation to improve the overall cold chain efficiency and safety.

[0043] In some embodiments, optimizing the cold chain logistics parameters for the cycle nodes according to the cold chain evaluation information to generate a logistics management strategy, including:

[0044] Projecting according to the evaluation cycle nodes and time relationships corresponding to the cold chain evaluation information into the timing relationship of the full cycle nodes to obtain subsequent optimized timing cycles; obtaining the optimizable parameters of the subsequent optimized timing cycles, and constructing an optimization evaluation function based on the optimizable parameters, where the optimizable parameters include one or more of temperature control parameters, transfer control parameters for cycle nodes, and logistics path adjustment parameters; calculating the margin for the cargo damage evaluation coefficient using the target damage assessment threshold of the cold chain items; searching for the optimizable parameters of the subsequent optimized timing cycles for the margin according to the optimization evaluation function to obtain logistics management parameters that meet the margin and minimize the cargo damage evaluation coefficient as the logistics management strategy.

[0045] Specifically, according to the evaluation results of each cycle node in the cold chain evaluation information, project these evaluation cycle nodes and their time relationships into the time sequence relationship of the full-cycle nodes. This means judging which cycle nodes need to be optimized preferentially based on the cargo damage evaluation coefficients of the cold chain items at each cycle node, so as to determine the subsequent optimization time sequence cycle. This subsequent optimization time sequence cycle refers to those nodes with high cargo damage evaluation coefficients due to large temperature fluctuations or excessive exposure time. Once the subsequent time sequence cycles that need to be optimized are determined, the next step is to extract the optimizable parameters of these cycles. These parameters usually include but are not limited to temperature control parameters, transfer control parameters at cycle nodes, and logistics path adjustment parameters. Among them, the temperature control parameters are the temperature set values of the cold chain items during transportation or storage, the working efficiency of the temperature control equipment, etc.; the transfer control parameters at cycle nodes are the residence time of the items during transfer, the adjustment range of the warehouse temperature control system, the temperature control during the loading and unloading operation, etc.; the logistics path adjustment parameters are the selection of the transportation path, whether to avoid high-temperature areas, etc. Subsequently, by weighting these three parameters, an optimization evaluation function is constructed. The goal of this function is to minimize the cargo damage evaluation coefficient based on the adjustment effects of each optimizable parameter, so as to find the most effective adjustment plan. During the optimization process, the target damage assessment threshold of the cold chain items is used to calculate the margin of the cargo damage evaluation coefficient. The target damage assessment threshold is the maximum cargo damage tolerance that the items can bear during the cold chain process. By comparing the current cargo damage evaluation coefficient with the target damage assessment threshold, the margin is calculated. The result of the margin calculation is a measure of how much temperature fluctuation or exposure time can still be tolerated in the current cold chain management without exceeding the quality damage limit of the items. For example, if the current cargo damage evaluation coefficient is 0.6 and the target damage assessment threshold is 0.8, then the remaining margin is 0.2. This margin provides a basis for subsequent optimization, meaning that the temperature, path, or transfer time can still be adjusted within a certain range without exceeding the tolerance range of the items. After determining the margin, the optimization process enters the search stage. According to the optimization evaluation function and the margin conditions, search for the optimizable parameters of the subsequent optimization time sequence cycle. Specifically, the search process is to find the best plan that can meet the margin conditions and minimize the cargo damage evaluation coefficient according to different combinations of parameters such as temperature control, path adjustment, and transfer control. For example, a possible optimization strategy is to adjust the transportation path to a route with better temperature control to reduce temperature fluctuations; adjust the transfer time to reduce the temperature exposure during transfer; refine the temperature control system settings to maintain a more stable temperature environment. Through this optimization search, a set of optimal logistics management parameters that meet the minimum cargo damage evaluation coefficient will finally be obtained, thus forming a logistics management strategy. This logistics management strategy will directly guide the management and execution of cold chain logistics, ensuring that the cold chain items are minimized in loss during transportation, maintaining their quality, and reducing unnecessary damage risks.
