[0034] Through modular design, the whole process management of project management, budget management, procurement management, inventory management and intelligent collaboration is realized. Each module has a clear division of labor and is responsible for different management links, such as project information management, budget preparation, procurement process and inventory monitoring, which effectively reduces confusion and repeated operations in the management process. Clear operation steps (such as adding project members, exporting budgets, and reviewing material applications) enable users to get started quickly and reduce time waste caused by complex processes. The first basic information of the project management module (project name, location, and building area) and the first budget information of the budget management module (budgeted project volume, actual expenditure) are shared in real time to provide reliable data support for the procurement and inventory modules. The permissions of project members can be dynamically adjusted according to role allocation, supporting efficient collaboration between different positions (such as ordinary employees, procurement auditors, warehouse managers, etc.) while ensuring data security. The budget management module supports export, subcategory addition and dynamic adjustment functions, and can quickly update the budget according to actual needs and changes to avoid the problem of over- or under-budgeting, and realize the comparison between budget and actual expenditure. Analysis, timely adjustment when deviations are found, and waste of project funds is reduced; the material application process of the procurement management module is clear (adding new materials, reviewing materials, and checking processes), and the entire process from demand to approval is traceable online, reducing communication costs. By reviewing the purchase order and the procurement application process, it is ensured that the procurement plan meets the project needs and budget, and duplicate or missed procurement is avoided; the inventory management module combines material entry, outbound orders, inbound orders, and transfer orders to fully control the status of material circulation, reduce waste or loss caused by poor management, set inventory safety lines, and provide real-time warnings for low or high inventory, optimize material procurement and storage strategies, add or adjust project members according to project needs, dynamically configure resources, and improve management flexibility. Material transfer is achieved through inventory management and intelligent collaboration modules, reducing idle resources and improving overall material utilization efficiency; procurement management and budget are linked in the system, and procurement plans are scientifically formulated based on budget and inventory conditions to reduce the impact of excessive procurement and price fluctuations, and clear operation steps and authority management are used to reduce data confusion and process interruptions caused by manual operation errors.

[0038] The operating steps of adding new material applications, reviewing material applications, and checking material processes are refined to make the process standardized and easy to operate, avoiding delays caused by improper operations. After the material application is completed, a purchase application can be directly initiated without repeatedly entering material information, reducing manual entry errors and time waste. From material demand to purchase execution, each link is clearly visible, and application, approval, and execution are completed in one go; each material application and purchase application supports viewing process records, including application initiation, approval, status update, etc., which facilitates problem tracing and clear responsibility, and the status of the application form (pending review, reviewed, purchased) The material application specifies the types and quantities of materials to avoid redundant purchases and waste of materials. The material information and quantity are edited in the purchase application to ensure that the purchase meets the actual needs and budget and avoid the risk of over-purchase or out-of-stock. The approval opinions are recorded for each approval to help optimize the material application and procurement process and improve the efficiency of material management. Both the material application and the procurement application must go through the review process to ensure the rationality and compliance of the application and reduce unnecessary material consumption or purchases. The reviewer can choose to agree or reject and Filling in the approval opinions helps to refine the process and improve the quality of material management. Each material application or purchase order needs to be reviewed, which eliminates the waste of resources caused by unnecessary applications or excessive purchases. All material applications and purchase applications are completed in the same system. Project members can check the progress of the application at any time to reduce the cost of cross-departmental communication. After the material application is completed, the procurement module receives information immediately to ensure the rapid connection between procurement and material demand and improve supply efficiency. The operation steps of each link are clear. Each participant (such as material personnel, purchasers, and auditors) completes their duties in the system, effectively reducing cross-role coordination problems. Through the visual viewing of the material and procurement process, the management can clearly understand the entire process of application and execution, provide a basis for optimizing the process, record all material application and procurement application data, and provide reference for the budget preparation and material management strategy of subsequent projects. The strict application and approval process reduces the risks of over-budget procurement and unreasonable material use, and provides a guarantee for the overall resource control of the project. By covering the entire process of material application and procurement application, closed-loop management from demand to execution is realized, solving the problems of opaque process, low efficiency, and resource waste in traditional procurement management. It has significant advantages in improving efficiency, reducing costs, optimizing processes and supporting decision-making, providing strong support for material management of construction projects.

It not only improves inventory control capabilities, but also significantly reduces the overall operating costs of the project by optimizing material circulation, reducing waste and providing decision support, ensuring the stability of project progress and quality.

[0044] The intelligent collaboration module includes a budget prediction unit, a budget execution monitoring unit and a dynamic budget adjustment unit; the budget prediction unit is connected to the budget execution monitoring unit, and the budget execution monitoring unit is connected to the dynamic budget adjustment unit;

[0045] The budget prediction unit is used to obtain the project budget, actual cost, budgeted engineering quantity and supply unit price in the first budget information; wherein the budgeted engineering quantity is calculated by building an engineering quantity prediction model based on the actual consumption of historical projects and the predicted consumption of historical projects. The formula of the engineering quantity prediction model is:

[0046]

[0047] Where: Q U is the estimated engineering quantity, Q L is the actual consumption of historical projects, Q LU Forecast consumption for historical projects;

[0048] The project budget is obtained by calculating the budgeted engineering quantity and supply unit price:

[0049]

[0050] Where: B U is the project budget, n is the number of project materials, Q Ui is the estimated engineering quantity of the i-th type of materials, U i is the supply unit price of the i-th category of materials, Q Li is the actual consumption of the historical items of the i-th category of materials, Q LUi Forecast consumption for historical items of class i materials.

[0051] The budget execution monitoring unit is used to obtain the actual engineering quantity and actual expenditure in real time, build a budget deviation calculation model based on the actual engineering quantity, budgeted engineering quantity, actual expenditure and project budget, and calculate the budget deviation rate. The formula of the budget deviation calculation model is:

[0052]

[0053] Where: θ Ut is the budget deviation rate at time t, Q t is the actual engineering quantity at time t, Q Ut is the budgeted engineering quantity at time t, B t is the actual cost at time t, B Ut is the project budget at time t;

[0055] B Ut ′=B Ut +θ Ut ;

[0056] Where: B Ut′ is the dynamically adjusted project budget, B Ut is the project budget at time t, θ Ut is the budget deviation rate at time t.

[0057] The intelligent collaborative module realizes the scientific, dynamic and real-time nature of budget management through the collaborative work of the budget forecasting unit, the budget execution monitoring unit and the dynamic budget adjustment unit. It builds an accurate engineering quantity forecasting model by using the actual consumption and predicted consumption of historical projects, eliminating the budget deviation caused by lack of experience. The engineering quantity forecasting model formula takes into account the difference between actual consumption and predicted consumption, and dynamically corrects the budget engineering quantity to ensure the accuracy of budget data. The budget execution monitoring unit obtains the actual engineering quantity, actual expenditure and other data in real time to ensure that the budget execution status is synchronized with the construction progress. Through the budget deviation calculation model, the budget deviation is quantified into a specific deviation rate to help managers quickly understand the difference between the budget and actual execution. The deviation calculation model monitors the deviation of engineering quantity and expenditure at the same time, providing managers with a more comprehensive budget execution situation. The dynamic budget adjustment unit automatically adjusts the project budget according to the deviation rate and generates a dynamically adjusted budget to ensure that the budget can respond to changes in actual conditions in real time. The dynamic adjustment function can quickly correct deviations to avoid waste of resources caused by excessive budget or insufficient budget affecting the construction progress. The adjusted budget is directly based on the actual supply unit price and engineering quantity to ensure that the budget always fits the market dynamics and actual construction needs. After dynamic adjustment, resource allocation can be optimized according to real-time engineering quantity and material consumption, reducing idle or insufficient resources. The module is suitable for budget monitoring and adjustment of multiple projects, which is convenient for cross-project resource allocation and budget optimization. From budget forecasting to dynamic adjustment, the whole process is automatically calculated and adjusted by the system, reducing errors and management costs caused by manual intervention. Through budget deviation monitoring and dynamic adjustment functions, budget deviations can be discovered and corrected in time to avoid cost overruns or construction delays caused by budget out of control. The budget can be adjusted in real time according to changes in supply unit prices to effectively respond to risks brought by market fluctuations. The module records data such as budget, actual engineering quantity, actual expenditure and adjusted budget, which is convenient for reference for budget preparation and optimization of subsequent projects. Through deviation rate analysis, it provides managers with visual deviation data to help efficient decision-making. The combination of historical project data and real-time adjustment results is conducive to the optimization of future budget models and improves the long-term benefits of budget management. The intelligent collaboration module realizes the scientific nature of budget preparation, the real-time nature of budget execution and the dynamic nature of budget adjustment through the collaborative work of three units: budget forecasting, execution monitoring and dynamic adjustment. It can significantly improve the accuracy and flexibility of budget management, reduce costs and risks, and provide strong support for the optimal allocation of project resources.
