For ordinary technicians in this field, other accompanying drawings can be obtained based on these accompanying drawings without paying creative work.

[0018] The following is combined with Figure 1-2 This application is described in further detail.

[0019] Example 1 The embodiment of the present application discloses a management system for building materials.

[0020] Reference Figure 1 , a management system for building materials, comprising: An information collection module, used to input the storage information corresponding to the building materials based on a preset collection device, wherein the storage information includes the type of building materials, the quantity of each type of building materials and the storage time; The monitoring and analysis module is used to monitor the inventory status information of various building materials in real time and confirm the inventory accuracy assessment coefficient of various building materials; An inventory optimization module is used to analyze and process the inventory status information and the current project construction progress information, and to perform rationality analysis on the building materials based on the results of the analysis and processing, and to formulate an optimization strategy based on the results of the rationality analysis; The analysis and decision-making module is used to respond to the optimization strategy and conduct a comprehensive analysis of the building materials, thereby generating a comprehensive inventory evaluation coefficient corresponding to the target warehouse, and managing the building materials based on the comprehensive inventory evaluation coefficient.

[0021] Furthermore, the inventory status information corresponding to each type of building material includes the actual inventory quantity, storage location and production batch corresponding to each type of building material.

[0022] It should be noted that real-time monitoring of the inventory status information corresponding to various building materials and confirmation of the inventory accuracy assessment coefficients corresponding to various building materials also include: Record the actual inventory quantity of each type of building material in real time and mark the actual inventory quantity as the inventory count quantity , and obtain the building material storage information entered by the information collection module, and extract the corresponding quantity of each type of building material from the storage information, and mark the quantity as the initial entry quantity ,in, It is represented by the number corresponding to each building material. ; By formula , confirm the inventory accuracy assessment coefficients corresponding to various types of building materials ,in, They are respectively expressed as the preset natural loss coefficient and usage loss coefficient. All are obtained by fitting historical data; Specifically, the natural loss coefficient is set as the loss of building materials caused by environmental factors (such as temperature, humidity, etc.) during storage, which can be obtained through fitting analysis of historical data.

[0023] The loss coefficient is set as the loss generated by the building materials during use, or it can be estimated by fitting through historical data; The inventory accuracy evaluation coefficients of various building materials With the preset inventory quantity valuation threshold Make a comparison; If the inventory accuracy assessment coefficients of various building materials All exceeded When the building materials inventory is entered accurately, If there is an inventory accuracy assessment coefficient corresponding to the building materials , then the error evaluation coefficient corresponding to the building material is required The inventory quantity corresponding to the building materials is adjusted, where the calculation formula of the error assessment coefficient is: .

[0024] Specifically, the inventory accuracy assessment coefficient can significantly improve the accuracy and efficiency of inventory management. First, it provides managers with a quantitative indicator that can reflect the accuracy of inventory quantities in the system in real time, thereby helping companies to promptly detect potential errors in inventory quantities and avoid material shortages or surpluses caused by inaccurate inventory quantities. Secondly, the inventory accuracy assessment coefficient can effectively identify problems in inventory management, such as material loss, loss, or recording errors, by comparing the data entered into the system with the actual inventory data. The above-mentioned assessment mechanism not only improves the transparency of inventory data, but also helps companies optimize inventory management processes and reduce errors caused by human intervention, thereby avoiding construction delays or material waste caused by inaccurate inventory data.

[0025] Furthermore, by adjusting the inventory quantity through the error assessment coefficient, the difference between inventory data and actual inventory can be effectively reduced, ensuring that the inventory quantity in the system is closer to the actual situation. The error assessment coefficient helps enterprises identify problems in inventory management by quantifying the deviation between inventory data and inventory data, and dynamically adjusts inventory data based on the above error assessment coefficient. For example, when the system finds that the error assessment coefficient of a certain material is large, the enterprise can take timely measures, such as adjusting inventory records, re-inventorying, or revising procurement plans. This adjustment mechanism can reduce operational risks caused by inaccurate inventory data and avoid material shortages or over-purchases.

[0026] It should be noted that the analysis and processing is performed based on the inventory status information and the current project construction progress information, and the rationality analysis of the building materials is performed based on the results of the analysis and processing, and the optimization strategy is formulated based on the results of the rationality analysis, specifically including: Collect the current project construction progress information in real time within the preset time interval, and compare the current project construction progress information with the historical project construction progress information stored in the cloud database to confirm the daily demand for various types of building materials, and then confirm the demand for various types of building materials within the preset time interval. ,in, Expressed as a preset time interval; Specifically, the current project construction progress information is compared with the historical project construction progress information stored in the cloud database, and the steps of confirming the daily demand corresponding to various types of building materials include the current project construction progress information including the task progress of each stage, construction area, construction cycle, material type and frequency of use, etc., while the historical project data in the cloud database contains the construction progress, material use records, daily demand, project scale and construction conditions of similar projects. Through the analysis of historical project data, the system can use big data analysis and machine learning technology based on the principle of similarity to identify projects similar to the current project in terms of scale, construction stage, material use pattern, etc. The system can compare the material use of the current project and the historical project at different construction stages, extract the material use pattern that best matches the current construction progress, and then derive the daily demand of various types of building materials. Specifically, the material daily demand of the current project can be predicted based on the material consumption rate of similar stages in the historical project through time series analysis, regression analysis and other methods, and updated in real time according to the dynamic changes in the construction progress. This method can not only improve the accuracy of material demand prediction, but also effectively avoid material surplus or shortage, and ensure the smooth progress of the project.

[0027] By formula , confirm the inventory rationality coefficients corresponding to various types of building materials , the inventory rationality coefficients corresponding to various types of building materials Compared with the preset inventory rationality threshold Compare the intervals; If there is a corresponding inventory rationality coefficient for building materials , it is determined that the actual inventory quantity corresponding to the building material has a risk of excess, and a first warning signal is output; If there is a corresponding inventory rationality coefficient for building materials In When the actual inventory quantity of the building materials is between , it is determined that the actual inventory quantity of the building materials is normal, and there is no need to output a warning signal; If there is a corresponding inventory rationality coefficient for building materials , it is determined that there is a risk of shortage in the actual inventory quantity corresponding to the building material, and a second warning signal is output.

[0028] Furthermore, after determining that the actual inventory quantity corresponding to the building materials has a risk of shortage and outputting a second warning signal, the method further includes: By formula , confirm the corresponding reorder points for various types of building materials ,in, Indicated as number Preset safety stock values ​​for building materials; Specifically, the preset safety stock value is set as the additional inventory amount set to cope with demand fluctuations or supplier delays, which is usually obtained based on historical data or demand fluctuations; If the actual inventory quantity of a building material is lower than the reorder point of the building material, a replenishment warning signal is output. The reorder points of various building materials can be dynamically adjusted according to the daily demand and delivery cycle. That is, when the daily demand and delivery cycle of various building materials change, the reorder points of various building materials also change accordingly.

[0029] Specifically, changes in the daily demand and delivery cycle corresponding to each type of building material affect the demand for each type of building material within a preset time interval.

[0030] It should be noted that a comprehensive analysis of building materials is conducted to generate a comprehensive inventory evaluation coefficient corresponding to the target warehouse, and building materials are managed based on the comprehensive inventory evaluation coefficient, specifically including: By formula , confirm the inventory comprehensive evaluation coefficients corresponding to various types of building materials ,in, It is expressed as the preset allowable difference of inventory accuracy assessment coefficient. Expressed as a preset weight coefficient; Substitute the inventory comprehensive assessment coefficients corresponding to various types of building materials into the formula , calculate the comprehensive inventory evaluation coefficient corresponding to the target warehouse ,in, Expressed as the number of building material types, It is expressed as the correction factor corresponding to the comprehensive evaluation coefficient of the inventory of various building materials; It can be obtained by fitting historical data; The inventory comprehensive evaluation coefficient corresponding to the target warehouse Combined with preset inventory assessment thresholds Make a comparison; If the inventory comprehensive evaluation coefficient corresponding to the target warehouse , then it is determined that the inventory management corresponding to the target warehouse is reasonable; If the inventory comprehensive evaluation coefficient corresponding to the target warehouse , then it is determined that there are problems with the inventory management corresponding to the target warehouse and adjustments need to be made in a timely manner.

[0031] Furthermore, it also includes: Obtain inventory status information corresponding to each type of building material, extract production batches corresponding to each type of building material from the inventory status information, and obtain the remaining shelf life corresponding to each type of building material based on the production batches corresponding to each type of building material ; Get the daily demand for various building materials , and then through the formula , confirm the shelf life risk coefficients of various building materials ,in, It is expressed as the correction factor corresponding to the shelf life risk factor of various building materials; The corresponding shelf life risk coefficients of various building materials Compared with the preset shelf life risk threshold Make a comparison; If there is a shelf life risk factor corresponding to building materials , it is determined that the building materials have a high risk and an expiration warning signal is output.
