TECHNICAL FIELD

[0001] The application belongs to the technical field of medical material management, and particularly relates to a medical material intelligent supply chain management scheme and system based on multi-modal AI. BACKGROUND

[0002] With the continuous improvement of the efficiency and safety of the supply chain in the medical industry, hospitals and medical institutions have higher requirements for material management. In a typical medical material supply chain, the whole process of materials from procurement, warehousing, distribution to use and scrap involves multiple links and multiple data types, including physical properties, batch information, procurement and use records, warehouse environment monitoring data, etc. The current medical material supply chain has core pain points such as process fragmentation, high inventory cost, high regulatory risk, and low coordination efficiency. Traditional management relies on manual operation, resulting in consumable waste, long turnover cycle, and difficulty in meeting the DRG / DIP medical insurance cost control requirements. Although existing technical solutions such as RFID intelligent cabinets and SPD systems achieve single-point digitization, the hardware data is isolated, the system compatibility is poor, and there is a lack of multi-source perception fusion and dynamic decision-making capability, which cannot support whole-chain lean management.

[0003] The existing system mainly relies on manual inventory or simple inventory difference alarms, and it is difficult to quantify and warn in time about unexpected consumption and physical damage of materials. Often, problems can only be found after inventory or loss reporting, which has caused resource waste and safety hazards. There is a lack of a unified multi-source data fusion platform, resulting in poor end-to-end traceability of the whole life cycle of materials. Many hospitals still use fixed replenishment cycles or quantitative replenishment methods based on historical average usage, which cannot dynamically combine current consumption, forecast demand, and material status for intelligent replenishment scheduling, easily leading to overstocking or stockout situations, increasing operating costs and affecting clinical safety.

[0021] Please refer to the accompanying Figure 1 As shown in the accompanying drawings, a medical material intelligent supply chain management scheme based on multi-modal AI is provided, including: S1, acquire physical feature data, identity data and business flow data of medical supplies, and generate whole life cycle information of the supplies; S2, acquire clinical demand information and inventory state data, and generate current consumption of the supplies; S3, acquire the weight of the supplies taken and the charging record of the supplies based on the whole life cycle information of the supplies, and generate unexpected consumption of the supplies based on the weight of the supplies taken and the charging record of the supplies; S4, acquire storage state image data of the supplies based on the whole life cycle information of the supplies, and acquire physical damage risk of the supplies based on the storage state image data of the supplies; S5, acquire expiration date data and storage environment information of the supplies based on the whole life cycle information of the supplies, and predict time-sensitive consumption of the supplies based on the expiration date data and the storage environment information of the supplies; S6, acquire comprehensive consumption of the supplies based on the current consumption of the supplies, the unexpected consumption of the supplies, the physical damage risk of the supplies and the time-sensitive consumption of the supplies, acquire a dynamic consumption threshold based on historical consumption data, determine whether the comprehensive consumption of the supplies exceeds the dynamic consumption threshold, and execute corresponding management strategies based on the determination result.

[0022] As in the above steps S1 to S6, the physical characteristics (such as weight, volume and appearance), identity (such as batch number, production date and material category) and business flow data (such as purchase order, material billing record and department consumption record) of the materials are collected by using radio frequency identification (RFID), bar code, sensor and other technologies, and are fused to build an electronic file (material full life cycle information) of each material, to realize end-to-end traceability from production, transportation to final disposal. Based on the latest clinical demand (such as doctor / nurse initiated application) and real-time inventory status (such as inventory checking data of the warehouse system), the current consumption of the material is calculated, the normal consumption level is reflected, the "taking weight" and "billing record" (such as the weight corresponding to the actual taking weight and billing amount) are extracted from the full life cycle information, the unexpected consumption index is calculated, the storage state is photographed regularly or in real time, combined with visual AI detection (such as object detection and defect recognition network based on deep learning), hidden dangers such as packaging damage, deformation and leakage are identified, and physical damage risk is output. According to the material expiration date data (production / expiry date) and warehouse environment monitoring information (temperature), the timeliness consumption caused by expiration and environmental abnormalities is predicted. The current consumption, unexpected consumption, physical damage risk and timeliness consumption are fused according to the weight to obtain the comprehensive consumption index of the material. The threshold is dynamically calculated based on the historical consumption fluctuation data, and it is judged whether the comprehensive consumption is beyond the normal range. For the case beyond the threshold, the warning or management strategy is triggered: such as automatic replenishment, inventory review, storage adjustment, environment adjustment or waste loss, etc. Through multi-modal data fusion, the full life cycle and full link tracking of the material is realized, the information silos are eliminated, the management transparency is improved, the unexpected consumption and physical damage risk are identified early, the large accumulation or clinical supply interruption is avoided, the operation cost is reduced, the dynamic consumption threshold is used to realize the demand replenishment and cross-warehouse allocation, the inventory turnover rate and supply guarantee rate are considered, the environment monitoring and expiration date information are included in the processing, the storage of temperature and humidity sensitive materials under the best conditions is ensured, the loss caused by expiration or environmental abnormalities is reduced, the waste rate and overstocking risk are comprehensively reduced, and the timely availability of key materials for clinical use is ensured, the economic benefit and safety of the medical material supply chain are improved.

[0023] In a preferred embodiment, the step of acquiring physical characteristic data, identity data and business flow data of the medical material, and generating material full life cycle information, comprises: S101, acquiring physical characteristic data of the medical material, wherein the physical characteristic data includes weight, volume and appearance; S102, acquiring identity data of the medical material, wherein the identity data includes material category and material expiration date data; S103, acquiring business flow data of the medical material, wherein the business flow data includes purchase order, material billing record and department consumption record; S104, the physical characteristic data, identity data and business flow data of each medical material are associated and integrated to generate material life cycle information.

[0024] As in the above steps S101 to S104, each piece of medical material is weighed, volume measured and appearance photographed by using embedded sensors (such as electronic scales, volume measuring instruments, 3D scanners or cameras), and the collected weight, length x width x height and image information are uploaded to the material management platform in real time. In the warehouse or intelligent storage cabinet link, the material is attached or injected with a unique identifier (RFID tag, barcode or two-dimensional code), records the category code, production batch, production / expiry date and other key information, queries and verifies the identifier in combination with the enterprise resource planning (ERP) system or barcode management system, ensures that the material category, specification and shelf life are accurate, obtains the purchase order information from the procurement system, including the supplier, order quantity and expected arrival time, obtains the billing records corresponding to the material warehouse in and out from the financial and billing systems to reflect the actual use cost, and grabs the material consumption log of each department from the hospital information system (HIS) or department management system, including the use time, amount and using department. The above three types of data are indexed by the unique identifier of the material and stored in the middle database according to the time line, a complete track from warehouse entry, inspection, distribution, use, loss reporting and recovery is constructed, a graph database or time series database model is used to support multi-dimensional query and traceability according to the material, batch or department dimensions, and the data is cleaned, de-duplicated and synchronized to ensure information consistency and real-time performance. The three-dimensional holographic record of the identity, physics and business of each piece of medical material can be achieved, the source, shelf life and use of the material can be traced at any time, the traceability and compliance are greatly improved, the multi-source data is uniformly associated and managed in the same platform, the information silos and manual input errors are eliminated, the management decisions are based on reliable data, the whole process of the material from warehouse entry to use is monitored, the wrong and missing use and expired loss are reduced, the operation cost is reduced, and the clinical use and drug safety are ensured.

[0025] In a preferred embodiment, the step of obtaining clinical demand information and inventory status data and generating the current consumption of the material includes: S201, obtaining clinical demand information and inventory status data; S202, obtaining the corresponding clinical demand value based on the clinical demand information; S203, obtaining the corresponding last period inventory value and current inventory value based on the inventory status data; S204, obtaining the current consumption of the material based on the clinical demand value, the last period inventory value and the current inventory value.

[0026] As in the above steps S201 to S204, the clinical demand information (from the department application sheet or electronic medical order, pushed by the hospital information system (HIS) in real time) and the inventory state data (obtained through the inventory checking system or the intelligent storage cabinet, including the last period (the end of the previous statistical period) and the current inventory) are captured in real time or at a fixed time, the clinical demand information is summarized, the number of material application and the number of approved applications of each department in the same statistical period are counted, and a clinical demand value is aggregated to reflect the real clinical rigid demand. The last period inventory value (taking the inventory snapshot at the end of the previous statistical period) and the current inventory value (taking the real-time inventory at the current time or at the end of the period) are obtained from the inventory database or the storage cabinet database. The clinical demand value, the last period inventory value and the current inventory value are comprehensively calculated to obtain the current consumption of materials, and the calculation formula of the current consumption of materials is , wherein U represents the current consumption of materials, L represents the clinical demand value, represents the last period inventory value, represents the current inventory value. The clinical demand and the inventory change are integrated to realize multi-dimensional quantification of material consumption, avoid deviation caused by single data, provide reliable basis for replenishment, allocation and inventory optimization, accurately monitor the consumption rate, help to reduce operating costs and waste, and at the same time guarantee the continuous supply of key materials in clinical practice.

[0027] In a preferred embodiment, the step of obtaining the material taking weight and the material billing record based on the material full life cycle information, and generating the unexpected consumption of materials based on the material taking weight and the material billing record, comprises: S301, obtaining the material taking weight and the material billing record based on the material full life cycle information; S302, obtaining the material billing taking weight based on the material billing record; S303, obtaining the taking deviation weight based on the material billing taking weight and the material taking weight, and marking it as the unexpected consumption of materials.

[0028] As in steps S301 to S303 described above, the complete life cycle record of the material is retrieved in the middle platform database or graph database indexed by the unique identification of the material, the material taking weight (recorded by the sensor (such as an electronic scale) or smart cart scanning of the lower computer, real-time record of the weight change at each time of taking), and the material billing record (extracted from the financial system or billing subsystem, including the billing time, billing unit price, and billing weight). The billing taking weight is extracted from the billing record. If the same batch of material generates multiple billing in a statistical period, the billing taking weights are accumulated to obtain the total billing taking weight of the period. Combined with the actual taking weight reported by the sensor, the difference between the material billing taking weight and the material taking weight is calculated, which is the taking deviation weight. The cross comparison of the taking weight and the billing weight can timely find abnormality such as missing billing (taking more than billing) or overbilling (billing more than taking), enhance the consistency of accounts and reality, quickly locate the specific taking time, operator or system interface point for the deviated link, support post-event auditing and responsibility identification, and include non-expected consumption into key monitoring indicators to help managers evaluate the hidden loss caused by improper operation, missing accounting, or theft and waste.

[0029] In a preferred embodiment, the step of obtaining the material storage state image data based on the material full life cycle information and obtaining the material physical damage risk based on the material storage state image data comprises: S401, obtaining material storage state image data based on material full life cycle information; S402, obtaining a plurality of perspective material storage images based on the material storage state image data, and constructing a plane rectangular coordinate system in each perspective material storage image; S403, obtaining a plurality of material edge profile inflection point coordinates in each perspective material storage image based on the plane rectangular coordinate system; S404, obtaining a material shape image standard area of each perspective; S405, generating material storage deformation based on the plurality of material edge profile inflection point coordinates in each perspective material storage image and the corresponding material shape image standard area, and marking as a physical damage risk.

[0030] As in the above steps S401 to S405, with the unique identification of the material as the index, the high-definition images of the material in each storage link (such as warehousing, shelving, allocation, inventory) are pulled from the material management platform or image repository, ensuring coverage of the storage state at different time points and scenes. For each set of storage scene images, select at least two or more mutually orthogonal or semi-orthogonal perspectives (such as front, side, top view), and on each image, construct a planar rectangular coordinate system (coordinate origin and unit length determined by calibration objects or checkerboard calibration board) according to the shooting device calibration results, so that subsequent deformation measurement has spatial consistency. Using image processing algorithms (such as Canny operator + Hough transform or deep learning-based instance segmentation network), accurately detect the outer contour of each piece of material in the coordinate system, and extract several key corner coordinates to form a polygonal contour representation of the material at that perspective. Corresponding to the ideal shape or undamaged state of the material, the standard contour area is predefined and stored in the same coordinate system (i.e. the projected area of the material when it is perfectly packaged and correctly placed). The material storage deformation is calculated by integrating the multiple material shape image area coordinates in the material storage images of each perspective and the corresponding material shape image standard area, and is marked as a physical damage risk. The calculation formula of the material storage deformation is , where P represents the material storage deformation, k represents the number of material shape image areas in the material storage images of multiple perspectives, k = 1, 2, 3…t, represents the material shape image area in the kth perspective of the material storage image, represents the material shape image standard area corresponding to the kth perspective of the material storage image, where the calculation of the material shape image area can be obtained using the area formula, for example, the shoelace theorem. Taking the shoelace theorem as an example, the calculation formula of the material shape image area is , where represents the material shape image area, h represents the number of multiple material edge contour corner coordinates in the material storage image of each perspective, h = 1, 2, 3…m, represents the x-axis coordinate point of the hth material edge contour corner in the material storage image of each perspective, represents the x-axis coordinate point of the h+1th material edge contour corner in the material storage image of each perspective, represents the y-axis coordinate point of the hth material edge contour corner in the material storage image of each perspective, and The y-axis coordinate point of the h+1th material edge profile inflection point in the material storage image of each view angle is represented, and when h takes the value of m, m+1 is represented as 1. The multi-view and coordinate system-based profile inflection point extraction and area comparison avoid misjudgment caused by occlusion or perspective distortion under a single view angle. The whole process can be automatically executed in an intelligent warehouse system, real-time monitoring of the material packaging and stacking state is not necessary for manual visual inspection, and the efficiency is significantly improved. Through deformation quantization monitoring, timely alarm can be given when the material packaging integrity is damaged at the initial stage, i.e., when a small indentation or deformation just appears, to avoid material loss, quality risk or clinical accidents caused by serious damage.

[0031] In a preferred embodiment, the step of obtaining material validity period data and material storage environment information based on material life cycle information, predicting material timeliness loss based on material validity period data and material storage environment information, comprises: S501, obtaining material validity period data and material storage environment information based on material life cycle information; S502, obtaining standard temperature validity time and stored time of the medical material based on the material validity period data; S503, obtaining standard storage temperature, actual average storage temperature and temperature coefficient based on the material storage environment information; S504, obtaining material timeliness loss of the medical material based on standard temperature storage validity time, stored time, standard storage temperature, actual average storage temperature and temperature coefficient.

[0032] In the above steps S501 to S504, the validity period data (production / expiry date, used to calculate the shelf life length under standard storage) and storage environment information (temperature monitoring records of the warehouse or transportation vehicle, including temperature values at each time point) are pulled from the life cycle database with the material unique identifier as the index. A standard temperature validity time (maximum number of days available under standard storage temperature (e.g., 4°C) specified by the manufacturer or regulatory agency) is pre-set in the database, and the stored time (cumulative storage days from the date of material storage or last review) is extracted. The standard storage temperature is extracted from the pre-set database, and the temperature mean value in the monitored time period, i.e., the actual average storage temperature, is obtained. The storage temperature coefficient of the medical material (usually taking a value of 1.5-2.5, used to describe the reaction acceleration multiple when the temperature increases by 10°C) is extracted from the pre-set database. The standard temperature storage validity time, stored time, standard storage temperature, actual average storage temperature and temperature coefficient are comprehensively calculated to obtain the material timeliness loss of the medical material. The calculation formula of the material timeliness loss is , wherein represents the material timeliness loss, represents the standard temperature storage validity time, is expressed as the stored time, is expressed as the actual average storage temperature, is expressed as the standard storage temperature, Q is expressed as the temperature coefficient, is expressed as the actual remaining storage effective time, the accelerated influence of the actual temperature deviation on the stability of chemical and biological products is quantified as an equivalent time through the temperature coefficient, the inaccuracy of simply evaluating the expiration risk according to the calendar days is avoided, the consumption ratio can be continuously updated according to real-time environmental data, the materials that will exceed the standard are identified in advance, the clinical supply interruption and expiration loss are reduced, the equivalent storage days and the consumption ratio report of each batch of materials can be output, the regulatory compliance and audit requirements are met, and the environment and consumption track can be accurately reproduced when a complaint occurs.

[0033] In a preferred embodiment, the step of obtaining the comprehensive consumption of the materials based on the current consumption of the materials, the unexpected consumption of the materials, the physical damage risk of the materials and the timeliness consumption of the materials, and obtaining the dynamic consumption threshold based on the historical consumption data, determining whether the comprehensive consumption of the materials exceeds the dynamic consumption threshold, and executing the corresponding management strategy based on the determination result, includes: S601, obtaining the material weight, wherein the material weight includes the current consumption weight, the unexpected weight of the materials, the physical damage weight of the materials and the timeliness weight of the materials; S602, obtaining the comprehensive consumption of the materials based on the current consumption of the materials, the unexpected consumption of the materials, the physical damage risk of the materials, the timeliness consumption of the materials and the weight of the materials; S603, obtaining the dynamic consumption threshold based on the historical consumption data; S604, determining whether the comprehensive consumption of the materials exceeds the dynamic consumption threshold; If the comprehensive consumption of the materials does not exceed the dynamic consumption threshold, it is determined that the consumption of the materials is normal, a restocking strategy table is obtained, wherein the restocking strategy table includes a plurality of comprehensive consumption intervals of the materials and a corresponding restocking strategy of the materials for each comprehensive consumption interval of the materials, a corresponding restocking strategy of the materials is obtained from the restocking strategy table based on the comprehensive consumption interval of the materials corresponding to the comprehensive consumption of the materials, and medical materials are restocked based on the restocking strategy. If the comprehensive consumption of the materials exceeds the dynamic consumption threshold, it is determined that the consumption of the materials is abnormal, a consumption exceeding value of the comprehensive consumption of the materials exceeding the dynamic consumption threshold is obtained, a management strategy table is obtained, wherein the management strategy table includes a plurality of consumption exceeding value intervals and a corresponding alarm strategy and alarm restocking strategy for each consumption exceeding value interval, a corresponding alarm maintenance strategy and alarm restocking strategy are obtained from the management strategy table based on the consumption exceeding value interval corresponding to the consumption exceeding value, medical materials are processed based on the alarm maintenance strategy, and medical materials are restocked based on the alarm restocking strategy.

[0034] As in the above steps S601 to S604, the material weight, i.e. the current consumption weight, the material unexpected weight, the material physical damage weight and the material timeliness weight, is read from the pre-set database or the AI model training result. The sum of each weight is usually normalized to 1 to ensure that the comprehensive consumption is in a comparable scale. According to the weight, the material current consumption, the material unexpected consumption, the material physical damage risk and the material timeliness consumption are weighted and fused to generate a single material comprehensive consumption. The calculation formula of the material comprehensive consumption is , wherein Z represents the material comprehensive consumption, represents the current consumption weight, U represents the material current consumption, represents the material unexpected weight, F represents the material unexpected consumption, represents the material physical damage weight, P represents the material storage deformation, represents the material timeliness weight, represents the material timeliness consumption. The upper limit of the current normal range is obtained based on the historical consumption data to obtain a dynamic consumption threshold which can be automatically adjusted according to the seasonal and department demand fluctuations. If the material comprehensive consumption does not exceed the dynamic consumption threshold, it is determined that the material consumption is normal. From the replenishment strategy table, the corresponding replenishment frequency and replenishment amount (such as regular small batch replenishment, regular large batch replenishment, etc.) are obtained according to the pre-defined consumption interval (such as 0-5, 5-8). The replenishment instruction is automatically generated and issued to the supply chain system according to the table strategy to ensure that the inventory is maintained at a safe level. If the material comprehensive consumption exceeds the dynamic consumption threshold, it is determined that the material consumption is abnormal. From the management strategy table, the corresponding alarm strategy (SMS, email, billboard warning, on-site verification) and alarm replenishment strategy (such as emergency allocation, priority replenishment, limit use) are obtained according to the consumption exceeding value interval (such as 0-3, 3-6, 6-8). Alarm maintenance (such as starting inventory, manual review or package inspection) is performed, and at the same time, an urgent replenishment instruction is issued to ensure that the risk material is replenished in time or isolated. The multi-dimensional loss factors are fused into a single measurable index to avoid single index blind area and realize accurate grasp of the overall health status of the material. The dynamic threshold mechanism can automatically adjust according to the seasonal and event-driven demand fluctuations to effectively reduce the false positive and false negative rates. According to the different consumption levels, regular replenishment or emergency disposal can be flexibly selected to improve the supply chain efficiency. While ensuring the sufficiency of clinical materials, the inventory holding cost and operation risk are maximally reduced through fine grading replenishment and early warning.

[0035] In a preferred embodiment, the step of obtaining a dynamic consumption threshold based on historical consumption data comprises: S6031, obtaining a standard consumption threshold and a standard consumption value; S6032, obtaining a plurality of corresponding historical consumption values based on historical consumption data; S6033, obtaining a dynamic loss threshold value based on the standard loss threshold value, the standard consumption value and the plurality of historical consumption values.

[0036] As in the above steps S6031 to S6033, the standard loss threshold value (the highest loss allowed by the material under ideal environment and normal business conditions) and the standard consumption value (the normal consumption amount of the material (such as 1000 units per month) in the same statistical period) are defined in advance in the pre-set database or provided by experts and suppliers, the historical consumption values are extracted from the warehouse management system or the time series database according to the same statistical period (day / week / month), the standard loss threshold value, the standard consumption value and the plurality of historical consumption values are comprehensively calculated to obtain a dynamic loss threshold value, and the calculation formula of the dynamic loss threshold value is , wherein J represents the dynamic loss threshold value, represents the standard loss threshold value, represents the standard consumption value, and i represents the number of the plurality of historical consumption values, i = 1, 2, 3…n, represents the i-th historical consumption value, the dynamic threshold value automatically fluctuates up and down with the historical consumption level, can adapt to short-term demand fluctuations of seasonality or special events (such as large-scale operations and peak periods), reduces the false alarm rate, and the standard loss threshold value and the consumption value can be flexibly set by the hospital or the supplier according to the characteristics of the material, thereby improving the adaptability.

[0037] Please refer to the accompanying Figure 2 , the application also provides a medical material intelligent supply chain management system based on a multi-modal AI, which is used for the above-mentioned medical material intelligent supply chain management scheme based on a multi-modal AI, and comprises: a life cycle module, configured to obtain physical characteristic data, identity data and business flow data of the medical material, and generate whole life cycle information of the material; a current loss module, configured to obtain clinical demand information and inventory state data, and generate current loss of the material; an unexpected consumption module, configured to obtain material taking weight and material billing records based on the whole life cycle information of the material, and generate unexpected consumption of the material based on the material taking weight and the material billing records; a physical damage module, configured to obtain material storage state image data based on the whole life cycle information of the material, and obtain physical damage risk of the material based on the material storage state image data; a material shelf life module, configured to obtain material expiration date data and material storage environment information based on the whole life cycle information of the material, and predict material shelf life loss based on the material expiration date data and the material storage environment information; The material management module obtains comprehensive consumption of the material based on current consumption, unexpected consumption, physical damage risk and time-sensitive consumption of the material, and obtains a dynamic consumption threshold based on historical consumption data, determines whether the comprehensive consumption of the material exceeds the dynamic consumption threshold, and executes a corresponding management strategy based on the determination result.

[0038] The life cycle module obtains physical characteristic data (such as weight, volume, appearance), identity data (such as category, expiration date) and business flow data (such as purchase order, use record, billing record) of the medical material, performs data fusion on the multi-source information, and generates a full life cycle information portrait of each item of material. The current consumption module collects clinical demand information and inventory state data (such as last period and current inventory), and calculates the current consumption of the material based on these data, which is used to evaluate whether the current material is abnormally consumed. The unexpected consumption module obtains the unexpected consumption of the material by reading the use weight record and the billing record and comparing the deviation between the two. The physical damage module collects storage state image data (multi-angle) of the material, constructs a coordinate system on the image, extracts edge corner coordinates, and judges whether the material has physical damage risk such as compression damage and deformation in combination with the standard contour area. The material time limit module predicts the remaining effective use time of the material in the current environment in combination with the effective period data and real-time temperature and humidity environment data. The material management module fuses the aforementioned four types of consumption indicators, calculates the comprehensive consumption value of the material, dynamically generates a consumption threshold based on historical consumption trends, judges whether the current comprehensive consumption is abnormal, if normal, looks up the table to obtain the optimal replenishment strategy, automatically pushes the replenishment task, if abnormal, calculates the exceeding degree, triggers a hierarchical alarm and replenishment maintenance strategy, and performs abnormal traceability analysis, forming a full-chain data perception and feedback mechanism from warehousing, storage, use, consumption, abnormality and replenishment, realizing closed-loop control of medical material management, introducing image recognition, sensor collection, structured form, time series data and other multi-modal data sources, realizing comprehensive perception and recognition of the state of the material, and comprehensively calculating the consumption by using multi-factor weighting in combination with historical behavior data to dynamically set a management threshold, so that the management strategy is more personalized, precise and adaptive. Based on the dynamic consumption threshold, the demand replenishment and cross-warehouse allocation can be realized, the inventory turnover rate and the supply guarantee rate are taken into account, the environmental monitoring and expiration date information are included in the processing, the storage of temperature and humidity sensitive materials under the best conditions is ensured, the consumption caused by expiration or environmental abnormalities is reduced, the waste rate and excessive inventory risk are reduced, and the timely availability of key materials for clinical use is ensured, and the economic benefit and safety of the medical material supply chain are improved.
