Description

Technical Field

[0001] The present invention relates to the technical field of inventory management, and in particular to an inventory management system and method for the internal circulation of second-hand electronic products. Background Art

[0002] With the rapid development of the second-hand market, consumers' demand for cost-effective products has increased. Enterprises are faced with the challenge of how to efficiently manage second-hand inventory. The inventory management system is designed to effectively manage and optimize the storage, circulation and sales processes of second-hand electronic products.

[0003] The prior art has the following defects:

[0004] 1. When the existing management system puts second-hand electronic products into the warehouse, there are usually two methods: one is to put the second-hand electronic products into the warehouse directly, and the other is to put the second-hand electronic products into the warehouse and conduct quality inspection at the same time. On the one hand, this method may lead to the quality inspection of products that do not need quality inspection, thereby wasting quality inspection resources and reducing the efficiency of product entry. On the other hand, it may lead to the failure of quality inspection of products that need quality inspection, and the quality of the products cannot be guaranteed;

[0005] 2. The management system usually adopts a unified inventory method for second-hand electronic product warehouses, which may cause waste of resources and unnecessary operational interference. In addition, the inventory frequency is usually a fixed inventory frequency set manually in advance. The fixed inventory frequency may cause the inventory cycle to be too long, resulting in information delays, thereby affecting the turnover efficiency of the product.

[0006] Based on this, the present invention proposes an inventory management system and method for the internal circulation of second-hand electronic products. Before the product enters the warehouse, it is determined whether the product needs to be combined with the warehousing and quality inspection to avoid wasting quality inspection resources while ensuring product quality. After the product enters the warehouse, the warehouse is partitioned and the inventory frequency of each storage area is dynamically adjusted to avoid wasting resources and effectively ensure the turnover efficiency of the product. Summary of the invention

[0007] The purpose of the present invention is to provide an inventory management system and method for the internal circulation of second-hand electronic products to solve the shortcomings of the background technology.

[0008] In order to achieve the above-mentioned purpose, the present invention provides the following technical solution: an inventory management method for internal circulation of second-hand electronic products, the management method comprising the following steps:

[0009] Before products are put into storage, the products of the same batch are classified into products that have been inspected or products that are pending for quality inspection. Then, the characteristics of the products that are pending for quality inspection are analyzed based on the rule engine, and it is automatically determined whether the storage and quality inspection of the products that are pending for quality inspection need to be combined according to the characteristics of the products that are pending for quality inspection.

[0010] Products that do not require quality inspection are put into storage directly. Products that require quality inspection are put into storage and quality inspection is carried out at the same time. After the quality inspection, a quality inspection list is automatically generated. Qualified products are automatically put into storage, and unqualified products are transferred to the isolation area.

[0011] After the same batch of products is put into storage, the warehouse is divided into several storage areas according to the product types. After regularly obtaining multi-source data of the storage areas, it is analyzed whether the inventory frequency of the storage areas needs to be optimized and adjusted, and the corresponding management strategy is generated based on the analysis results.

[0012] In a preferred embodiment, based on the rule engine analyzing the characteristics of the product to be inspected, the processing logic of the rule engine is:

[0013] Obtain the transportation impact factor and turnover index of the product to be inspected, normalize the transportation impact factor and turnover index of the product to be inspected, map the value range of the transportation impact factor and turnover index to [0,1], and obtain the normalized value of the transportation impact factor and the normalized value of the turnover index;

[0014] The normalized value of the transportation impact factor is subtracted from the normalized value of the turnover index to obtain the quality inspection coefficient, and the obtained quality inspection coefficient is compared with the preset quality inspection threshold. The quality inspection threshold is used to determine whether the product under quality inspection needs to be inspected;

[0015] If the quality inspection coefficient is less than or equal to the quality inspection threshold, it is judged that the products pending quality inspection do not need quality inspection. If the quality inspection coefficient is greater than the quality inspection threshold, it is judged that the products pending quality inspection need quality inspection. The products pending quality inspection that need quality inspection will be put into storage and combined with the quality inspection.

[0016] In a preferred embodiment, analyzing whether it is necessary to optimize and adjust the inventory frequency of the storage area, and generating a corresponding management strategy based on the analysis result, includes the following steps:

[0017] Regularly obtain multi-source data of the storage area, including product in-and-out frequency, environmental fluctuation index, and quality inspection index, and comprehensively calculate the product in-and-out frequency, environmental fluctuation index, and quality inspection index to obtain the adjustment coefficient;

[0018] Compare the adjustment coefficient with the preset adjustment threshold. If the adjustment coefficient is less than the adjustment threshold, the analysis does not need to optimize the inventory frequency of the storage area. If the adjustment coefficient is greater than or equal to the adjustment threshold, the analysis needs to optimize the inventory frequency of the storage area. The adjustment algorithm is: , where is the adjusted inventory frequency, is the inventory frequency before adjustment, To adjust the coefficient, the management system takes inventory of the storage area at the adjusted inventory frequency.

[0019] In a preferred embodiment, the product in-and-out frequency, environmental fluctuation index and quality inspection index are comprehensively calculated to obtain the adjustment coefficient, which is expressed as follows: , where is the adjustment coefficient, The frequency of product entry and exit, Environmental volatility index, is the quality inspection index, , , are the adjustment coefficients of product in-and-out frequency, environmental fluctuation index, and quality inspection index, respectively, and , , Both are greater than 0.

[0020] In a preferred embodiment, the logic for obtaining the quality inspection index is: obtaining the quality inspection coefficients of all products in the storage area, and the quality inspection coefficient of the product without a quality inspection coefficient is 0;

[0021] The quality inspection coefficients of all products are set up, and the average quality inspection coefficient and the standard deviation of the quality inspection coefficient in the set are calculated. The expression is: , where For the The quality inspection coefficient of each product, is the number of products in the storage area, is the average quality inspection coefficient, is the standard deviation of the quality inspection coefficient;

[0022] Generate a quality inspection index based on the average quality inspection coefficient and the standard deviation of the quality inspection coefficient;

[0023] If the average quality inspection coefficient is less than or equal to the quality inspection threshold, and the standard deviation of the quality inspection coefficient is less than or equal to the standard deviation threshold, the quality inspection index ;

[0024] If the average quality inspection coefficient is less than or equal to the quality inspection threshold, and the standard deviation of the quality inspection coefficient is greater than the standard deviation threshold, the quality inspection index ;

[0025] If the average quality inspection coefficient is greater than the quality inspection threshold, and the standard deviation of the quality inspection coefficient is greater than the standard deviation threshold, the quality inspection index ;

[0026] If the average quality inspection coefficient is greater than the quality inspection threshold, and the standard deviation of the quality inspection coefficient is less than or equal to the standard deviation threshold, the overall quality inspection coefficient of the analysis storage area is unstable, and the quality inspection index .

[0027] In a preferred embodiment, the calculation logic of the environmental fluctuation index is: obtain the temperature, humidity, and air flow velocity of the storage area, and calculate the temperature standard deviation, humidity standard deviation, and air flow velocity standard deviation over a period of time, and sum the temperature standard deviation, humidity standard deviation, and air flow velocity standard deviation to obtain the environmental fluctuation index.

[0028] In a preferred embodiment, the calculation logic of the transportation impact factor is: obtain the temperature deviation value, humidity deviation value and vibration intensity of the same batch of second-hand electronic products during transportation, and calculate the transportation impact factor by weighted calculation of the temperature deviation value, humidity deviation value and vibration intensity. The expression is: , where is the transport influencing factor, is the temperature deviation value, is the humidity deviation value, is the vibration intensity, , , are the weights of the influencing factors of temperature, humidity and vibration respectively.

[0029] In a preferred embodiment, after the same batch of products is put into storage, the warehouse is divided into several storage areas according to the product types, including the following steps:

[0030] Classify the products in the same batch, identify the different types of products in the same batch, classify them according to the attributes of each product, and allocate the products to the corresponding storage areas;

[0031] Automatically divide or adjust the storage area of ​​the warehouse according to the type, quantity and space requirements of the incoming products. After the storage area for each product category is determined, mark the storage area;

[0032] Automatically generate a warehouse allocation list based on the divided storage areas to guide operators to store products in the corresponding areas. Scan and record the location information of each product after it enters the warehouse, so that the actual location of the product in the management system is synchronized with the data.

[0033] Establish identification and management information for different storage areas, mark the locations in the warehouse layout, associate product information with storage areas, and mark the identification information of storage areas through electronic tags, RFID or QR codes.

[0034] In a preferred embodiment, a quality inspection list is automatically generated after quality inspection, qualified products are automatically put into storage, and unqualified products are transferred to an isolation area, including the following steps:

[0035] Receive information about products to be put into storage, extract relevant information of the products from the database, directly skip the quality inspection process for products that do not require quality inspection and proceed with storage operations; automatically start the quality inspection process for products that require quality inspection. When products that require quality inspection are put into storage, quality inspection and storage operations start simultaneously;

[0036] The products are quality checked by automated testing equipment. After the quality inspection is completed, a quality inspection list is automatically generated.

Before the product is put into storage, the management system determines whether the product needs to be put into storage and combined with the quality inspection, avoiding the waste of quality inspection resources while ensuring product quality. After the product is put into storage, the warehouse is partitioned and the inventory frequency of each storage area is dynamically adjusted to avoid waste of resources and effectively ensure the turnover efficiency of the product. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the drawings required for use in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments recorded in the present invention. For ordinary technicians in this field, other drawings can also be obtained based on these drawings.

[0044] Figure 1 The present invention is a flow chart of the method. DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0046] Example 1: Please refer to Figure 1 As shown, this embodiment provides an inventory management method for internal circulation of second-hand electronic products, and the management method includes the following steps:

[0047] Before the products are put into storage, the management system will first classify the products of the same batch into products that have been confirmed by quality inspection or products that are pending for quality inspection. This step can be determined based on the database, and then the characteristics of the products that are pending for quality inspection are analyzed based on the rule engine. Based on the characteristics of the products that are pending for quality inspection, it is automatically determined whether it is necessary to merge the storage and quality inspection of the products that are pending for quality inspection. Through this step, firstly, it can avoid quality inspection of products that do not need quality inspection, which wastes quality inspection resources and reduces the efficiency of product storage. Secondly, it can avoid that products that need quality inspection are not inspected, thus ensuring the quality of the products. Products that do not need quality inspection can be put into storage directly, while products that need quality inspection can be put into storage and quality inspection can be carried out at the same time. After the quality inspection, a quality inspection list is automatically generated, and qualified products are automatically put into storage. Unqualified products are transferred to the isolation area, and the unqualified products in the isolation area are manually processed for secondary processing (including repair, destruction, etc.). After the same batch of products is put into storage, the warehouse is divided into several storage areas according to the product type (for example, the storage area for each product is a storage area). The initial inventory frequency of each storage area is determined manually. After regularly obtaining multi-source data of the storage area, it is analyzed whether the inventory frequency of the storage area needs to be optimized and adjusted, and the corresponding management strategy is generated based on the analysis results. This step is to avoid resource waste and operational interference caused by unified inventory of warehouses, and to avoid information delays caused by too long inventory cycles in some storage areas, thereby affecting the turnover efficiency of products.

[0048] This application analyzes the characteristics of products pending quality inspection based on the rule engine, and automatically determines whether it is necessary to merge the warehousing and quality inspection of products pending quality inspection based on the characteristics of products pending quality inspection. After the same batch of products is put into storage, the warehouse is divided into several storage areas according to the product types. After regularly obtaining multi-source data of the storage area, it analyzes whether it is necessary to optimize and adjust the inventory frequency of the storage area, and generates corresponding management strategies based on the analysis results. Before the product is put into storage, the management system determines whether the product needs to be put into storage and combined with quality inspection to avoid wasting quality inspection resources while ensuring product quality. After the product is put into storage, the warehouse is partitioned and the inventory frequency of each storage area is dynamically adjusted to avoid wasting resources and effectively ensure product turnover efficiency.

[0049] Embodiment 2: Before the products are put into storage, the management system first classifies the products of the same batch into products that have been confirmed by quality inspection or products that are pending for quality inspection. This step can be determined based on the database and includes the following steps:

[0050] Collect basic information of the same batch of products, including product type, status, historical records, etc., and enter them into the database;

[0051] Quality inspection confirmed products: all products with known quality issues.

[0052] Products pending quality inspection: Products whose quality inspection requirements need to be determined through further parameters based on historical data and current status.

[0053] Example of a quality-checked product: A brand of used smartphones, which are known to have common battery failures in certain models, and historical data shows that the battery life of these phones is generally short. All phones of this model are marked as quality-checked products when they enter the warehouse, and must undergo a comprehensive quality inspection, including battery status, cosmetic damage, etc.

[0054] An example of a product pending quality inspection: A used laptop computer. Historical data shows that different users have different feedback on this model. Some users report overheating problems, but not all products have this problem. In this case, the system will classify it as a product pending quality inspection. When entering the warehouse, the system will analyze the parameters such as the age of the notebook and maintenance records to determine whether a quality inspection is required. If a laptop is more than 3 years old and has multiple maintenance records, the system may automatically require a quality inspection; otherwise, it can be directly entered into the warehouse.

[0055] The rule engine is used to analyze the characteristics of products that are pending quality inspection, and automatically determine whether it is necessary to combine the warehousing and quality inspection of products that are pending quality inspection based on the characteristics of products that are pending quality inspection, including the following steps:

[0056] The processing logic of the rule engine is as follows: obtain the transportation impact factor and turnover index of the product pending quality inspection, normalize the transportation impact factor and turnover index of the product pending quality inspection, map the value range of the transportation impact factor and the turnover index to [0,1], obtain the normalized value of the transportation impact factor and the normalized value of the turnover index, subtract the normalized value of the turnover index from the normalized value of the transportation impact factor to obtain the quality inspection coefficient. The larger the quality inspection coefficient of the product pending quality inspection, the more the product pending quality inspection needs quality inspection. In order to determine whether it is necessary to conduct quality inspection on the product pending quality inspection, we compare the obtained quality inspection coefficient with the preset quality inspection threshold. The quality inspection threshold is used to determine whether the product pending quality inspection needs quality inspection. If the quality inspection coefficient is less than or equal to the quality inspection threshold, it is determined that the product pending quality inspection does not need quality inspection. If the quality inspection coefficient is greater than the quality inspection threshold, it is determined that the product pending quality inspection needs quality inspection, and the quality inspection of the product pending quality inspection that needs quality inspection is combined with the warehousing and quality inspection.

[0057] The calculation logic of the transportation impact factor is: obtain the temperature deviation value, humidity deviation value and vibration intensity of the same batch of second-hand electronic products during transportation, and calculate the transportation impact factor by weighted calculation of the temperature deviation value, humidity deviation value and vibration intensity. The expression is: , where is the transport influencing factor, is the temperature deviation value, is the humidity deviation value, is the vibration intensity, , , are the weights of the influencing factors of temperature, humidity and vibration respectively;

[0058] The absolute value of the difference between the real-time temperature and the standard temperature is the temperature deviation value, and the absolute value of the difference between the real-time humidity and the standard humidity is the humidity deviation value;

[0059] The greater the transport impact factor, the worse the environment the product encounters during transportation, which may cause more quality problems. Therefore, the greater the transport impact factor, the more it is necessary to conduct quality inspection on the batch of used electronic products to ensure that the products are not damaged due to transportation problems.

[0060] The smaller the transportation impact factor is, the more likely the product is to be damaged. Therefore, in this case, the quality inspection requirements can be reduced and the product can be directly put into storage.

[0061] The calculation logic of the turnover index is as follows: obtain the product's outbound volume in a certain period of time (such as a week or a month) and the average inventory of the product in that period of time, and then divide the outbound volume in the same period of time by the average inventory to obtain the turnover index;

[0062] The larger the turnover index is, the higher the liquidity of the product is, which means that its inventory cycle is short and it will be sold or shipped out soon after entering the warehouse.

[0063] The smaller the turnover index is, the longer the inventory cycle of the product is, the longer the product stays in the warehouse, and the lower the liquidity is.

[0064] If the turnover rate of products is fast, it usually indicates that these products are high-demand products, will not stay in the warehouse for a long time in the short term, and may have been frequently inspected and used. At this time, the demand for quality inspection is lower, because these products have been fully tested in the market before leaving the warehouse, and the risk of damage or quality problems of fast-moving products is relatively small.

[0065] If the product turnover is slow and the product is stored in the warehouse for a long time, it may be affected by the environment (such as temperature, humidity, etc.), or problems may occur during the long storage period. Therefore, such products are more likely to need quality inspection before leaving the warehouse to ensure that there are no quality problems during the long storage period.

[0066] Products that do not require quality inspection are put into storage directly. Products that require quality inspection are put into storage and quality inspection is carried out at the same time. After the quality inspection, a quality inspection list is automatically generated. Qualified products are automatically put into storage, and unqualified products are transferred to the isolation area. Unqualified products in the isolation area are manually processed for secondary processing (including repair, destruction, etc.), including the following steps:

[0067] Receive detailed information on products to be put into storage (such as product model, source, batch, historical record, etc.), extract relevant information of the products from the database, directly skip the quality inspection process for products that do not require quality inspection, and perform storage operations. For products classified as requiring quality inspection, automatically start the quality inspection process. When the product is put into storage, quality inspection and storage operations start at the same time. According to the product characteristics, automatically retrieve the corresponding quality inspection standards, such as battery health, screen integrity, etc.

[0068] The product quality is checked by automated testing equipment or manual inspection. After the quality inspection is completed, a detailed quality inspection list is automatically generated, listing the test results, defects found and product status. Qualified products are automatically marked as "ready to be stored", and unqualified products are automatically marked as "need to be processed" and sent to the isolation area. Qualified products are assigned to the corresponding storage area, and inventory information is automatically updated to ensure that the incoming products are synchronized with the inventory database. The system transfers unqualified products to the isolation area for further processing. Manual operators process unqualified products in the isolation area, including:

[0069] Inspection and repair: For repairable products, arrange for repair and conduct re-quality inspection after repair.

[0070] Destruction: Arrange for the destruction of products that cannot be repaired or resold.

[0071] Recycling: For products with recycling value, arrange resource recycling.

[0072] After the quality inspection is completed, the quality inspection list is automatically generated and archived, and synchronized with the inventory system. The quality inspection list is saved in the database as the basis for subsequent quality control and product tracking, and the inventory data is updated. The products entering the warehouse are marked as "quality inspection passed" and included in the available inventory. The data of products that failed the quality inspection is analyzed, and a quality inspection report is generated to feedback common problems (such as a high return rate for a batch of products).

[0073] After the same batch of products is put into storage, the warehouse is divided into several storage areas according to the product types (for example, the storage area for each product is a storage area), including the following steps:

[0074] Classify products of the same batch into different types to ensure that product information is complete and accurate. Check the product model, batch, specification and other information to identify the different types of products in the batch. Classify each product according to its specific attributes (such as brand, model, specification, status, etc.) and assign it to the corresponding storage area. If there is a classification conflict (such as a new product type), the system will generate an alarm and recommend the creation of a new storage area.

[0075] Divide the warehouse storage area according to product types and make reasonable space planning. Automatically divide or adjust the warehouse storage area according to the type, quantity and space requirements of the incoming products. After the storage area for each product category is determined, the system marks the storage area as an exclusive area for storing this type of product to avoid mixing. Plan the spatial layout of different storage areas according to the product volume, storage requirements (such as temperature, humidity control, etc.) and frequency of entry and exit to maximize the use of warehouse resources.

[0076] According to the designated storage areas, products are allocated and actually arranged to be stored in the corresponding areas. According to the divided storage areas, the system automatically generates a storage allocation sheet to guide operators to store products in the corresponding areas. Operators transport products to the designated storage areas according to the allocation sheet and ensure that they are stored as required. The location information of each product after storage is scanned and recorded to ensure that the actual location of the product in the warehouse management system is synchronized with the data.

[0077] Establish identification and management information for different storage areas to facilitate subsequent query and management. Establish unique identification (such as number, name, product category label, etc.) for each storage area and mark the location in the warehouse layout diagram. Associate product information with storage areas in the system to ensure that the storage location and status of each type of product can be queried at any time. The identification information of the storage area can be marked in the form of electronic tags, RFID, QR codes, etc., to facilitate subsequent search and management.

[0078] The capacity and allocation rules of each storage area are adjusted in real time according to the usage of the storage area and inventory fluctuations. The system regularly checks the capacity utilization of the storage area to determine whether there is over-occupancy or insufficient capacity. According to the inventory changes in the warehouse or the addition of new product types, the system automatically adjusts the division of storage areas and product allocation rules to ensure the optimal utilization of different storage areas. If the storage demand for a certain product increases significantly, the system will automatically generate adjustment suggestions to reallocate storage areas or create new storage space.

[0079] The initial inventory frequency of each storage area is manually determined. After regularly acquiring multi-source data of the storage area, it is analyzed whether the inventory frequency of the storage area needs to be optimized and adjusted. Based on the analysis results, a corresponding management strategy is generated, including the following steps:

[0080] Regularly obtain multi-source data from the storage area, including product in and out frequency, environmental fluctuation index, and quality inspection index;

[0081] The adjustment coefficient is obtained by comprehensively calculating the product in-and-out frequency, environmental fluctuation index, and quality inspection index. The expression is: , where is the adjustment coefficient, The frequency of product entry and exit, Environmental volatility index, is the quality inspection index, , , are the adjustment coefficients of product in-and-out frequency, environmental fluctuation index, and quality inspection index, respectively, and , , All are greater than 0;

[0082] The calculation expression for the frequency of product entry and exit is: , where The frequency of product entry and exit. The number of times the product enters the warehouse during the monitoring period. The number of times the product is shipped out during the monitoring period. is the monitoring period;

[0083] High-frequency storage areas: The products in this storage area are highly mobile, and frequent storage increases the possibility of errors or omissions in inventory data. If the inventory frequency is low, it may cause a large deviation between the inventory data and the actual inventory. In order to ensure the accuracy and timeliness of inventory data, it is usually necessary to increase the inventory frequency and keep the inventory information updated in a timely manner. High liquidity also means that the warehouse has a greater demand for these products, and fast response and accurate inventory information are essential for business operations.

[0084] Storage areas with low frequency of in-and-out inventory: The product has low mobility, the product in-and-out is less, and the change range of inventory data is not large. In this case, the frequency of inventory counting can be appropriately reduced, because the stability of inventory data is relatively high, and too high an inventory counting frequency may lead to unnecessary waste of resources and operational interference. Therefore, the frequency of inventory counting can be appropriately reduced to reduce the impact on operations.

[0085] The calculation logic of the environmental fluctuation index is as follows: obtain the temperature, humidity, and air flow velocity of the storage area, and calculate the temperature standard deviation, humidity standard deviation, and air flow velocity standard deviation over a period of time. The temperature standard deviation, humidity standard deviation, and air flow velocity standard deviation are summed to obtain the environmental fluctuation index. The larger the environmental fluctuation index, the more unstable the environment of the storage area is, and the risk faced by the product increases. The inventory frequency needs to be increased to ensure that potential problems with the product are discovered in time to avoid losses.

[0086] Specifically, temperature fluctuations may cause electronic components to expand and contract, which in turn affects the structural integrity of internal components such as solder joints and chips, shortens the service life of the product, and even causes failures. High temperatures may cause components to overheat and age, while low temperatures may cause plastic casings to become brittle or LCD displays to become damaged. Frequent temperature changes have a significant impact on the reliability of components. Excessive humidity may cause corrosion of metal parts, oxidation of solder joints, or short circuits, especially for sensitive components such as motherboards and batteries. Low humidity may cause static electricity problems, especially in winter or dry climates, which may damage electronic components. Excessive airflow speeds may cause dust to be blown away in the warehouse and enter the interior of the product, affecting heat dissipation and component contact. Too low airflow speeds may result in poor air circulation, affecting the stability of the storage environment.

[0087] The larger the quality inspection coefficient of the product to be inspected, the more it needs to be inspected. The quality inspection coefficient can also be used to judge the overall status of all products in the storage area.

[0088] The logic for obtaining the quality inspection index is: obtain the quality inspection coefficients of all products in the storage area. It should be noted that the quality inspection coefficient of products without quality inspection coefficients is 0;

[0089] The quality inspection coefficients of all products are set up, and the average quality inspection coefficient and the standard deviation of the quality inspection coefficient in the set are calculated. The expression is: , where For the The quality inspection coefficient of each product, is the number of products in the storage area, is the average quality inspection coefficient, is the standard deviation of the quality inspection coefficient;

[0090] Generate a quality inspection index based on the average quality inspection coefficient and the standard deviation of the quality inspection coefficient;

[0091] If the average quality inspection coefficient is less than or equal to the quality inspection threshold, and the standard deviation of the quality inspection coefficient is less than or equal to the standard deviation threshold, the overall quality inspection coefficient of the storage area is stable, and the quality inspection index is ;

[0092] If the average quality inspection coefficient is less than or equal to the quality inspection threshold, and the standard deviation of the quality inspection coefficient is greater than the standard deviation threshold, the quality inspection coefficient of the analysis storage area is stable (but the quality inspection coefficient of some products is greater than the quality inspection threshold), the quality inspection index ;

[0093] If the average quality inspection coefficient is greater than the quality inspection threshold, and the standard deviation of the quality inspection coefficient is greater than the standard deviation threshold, the quality inspection coefficient of the analysis storage area is unstable (but the quality inspection coefficient of some products is less than or equal to the quality inspection threshold), the quality inspection index ;

[0094] If the average quality inspection coefficient is greater than the quality inspection threshold, and the standard deviation of the quality inspection coefficient is less than or equal to the standard deviation threshold, the overall quality inspection coefficient of the analysis storage area is unstable, and the quality inspection index .

[0095] The larger the value of the quality inspection index, the higher the frequency of inventory checking needs to be. This is because the quality inspection index reflects the overall product quality inspection coefficient of the storage area. A high quality inspection coefficient indicates that the product transportation process is risky, and due to the low turnover frequency, the product may not be inspected for a long time, and there are potential quality problems. Therefore, in order to discover and deal with these problems in a timely manner, it is necessary to increase the frequency of inventory checking to improve monitoring accuracy and ensure product quality.

[0096] The larger the adjustment coefficient, the more it is necessary to optimize the storage area's inventory frequency. The adjustment coefficient is compared with the preset adjustment threshold. If the adjustment coefficient is less than the adjustment threshold, it is analyzed that there is no need to optimize the storage area's inventory frequency. If the adjustment coefficient is greater than or equal to the adjustment threshold, it is analyzed that the storage area's inventory frequency needs to be optimized. The adjustment algorithm is: , where is the adjusted inventory frequency, is the inventory frequency before adjustment, is the adjustment coefficient;

[0097] The management system takes inventory of the storage area at the adjusted inventory frequency.

[0098] Embodiment 3: This embodiment is an inventory management system for internal circulation of second-hand electronic products, including a quality inspection and analysis module, a warehousing module, and an inventory optimization module;

[0099] Quality inspection analysis module: before products enter the warehouse, the products of the same batch are classified into products that have been inspected or are pending for quality inspection. Then, the characteristics of the products that are pending for quality inspection are analyzed based on the rule engine. Based on the characteristics of the products that are pending for quality inspection, it is automatically determined whether the entry of the products that are pending for quality inspection needs to be combined with quality inspection. The information of products that need quality inspection and those that do not need quality inspection is sent to the warehouse entry module.

[0100] Warehouse entry module: Products that do not require quality inspection are directly warehoused, while products that require quality inspection are warehoused and inspected at the same time. A quality inspection list is automatically generated after the quality inspection. Qualified products are automatically warehoused, and unqualified products are transferred to the isolation area. Product warehouse entry information is sent to the inventory optimization module;

[0101] Inventory optimization module: After the same batch of products is put into storage, the warehouse is divided into several storage areas according to the product types. After regularly obtaining multi-source data of the storage areas, it is analyzed whether the inventory frequency of the storage areas needs to be optimized and adjusted, and the corresponding management strategy is generated based on the analysis results.
