Description

Technical Field

[0001] The present invention relates to the technical field of information management, and particularly to a method and system for managing building engineering material information. Background Art

[0002] The technical field of information management focuses on the collection, storage, protection, processing, and transmission of data. In modern enterprises and organizations, information management is part of the core operations, used to optimize the decision-making process, enhance data security, improve operational efficiency, and promote information sharing. It is widely applied in multiple industries, including healthcare, education, finance, and construction, etc. With the development of technologies such as cloud computing, big data, and artificial intelligence, the field of information management is evolving rapidly to cope with the growing data processing requirements and complexities.

[0003] Among them, the method for managing building engineering material information focuses on how to effectively manage and use the material information in building engineering, including collecting material data from multiple sources, such as supplier information, material costs, performance parameters, and environmental impacts, and systematically processing the information for easy access and use by engineers and project managers. Its purpose is to optimize material selection, ensure material quality, control costs, and ensure that the project proceeds smoothly according to the specified standards and schedules. Through effective information management, higher economic efficiency and building quality can be achieved in construction projects.

[0004] The main deficiencies of existing information management technologies lie in the lack of the ability to comprehensively process and dynamically update building material information. In practical applications, information management technologies only stay at the stage of data collection and storage, and fail to effectively implement in-depth data analysis and real-time status feedback, resulting in the inability to fully utilize existing data in the decision-making process, increasing the uncertainty and risks of project costs. For example, without real-time updated data support, material procurement decisions are based on outdated or incomplete information, which is likely to cause resource waste or supply shortages. Existing technologies are unable to cope effectively with complex market environments and supply chain disruptions, unable to effectively predict and mitigate the impacts brought by risks, affecting the progress and quality of the entire project, which is particularly prominent in the highly competitive and rapidly changing construction industry, leading to project delays or cost overruns. Summary of the Invention

Through pre-negotiation with the suppliers, understand the recent production capacity and logistics arrangements to ensure that the suppliers can provide stable supply to meet the phased needs of the project. After selecting the matching materials and suppliers, considering the immediate demand for materials in each stage of construction, design a dynamic adjustment mechanism to adjust the material supply plan in real time according to the construction progress, generate the phased material demand table, and the formula is:

Conduct a monthly analysis of the price fluctuations of each key material in the past year, calculate the standard deviation and average price using the historical price data to evaluate the range of future price fluctuations. To improve the reliability of the data, industry price indices such as the building material price index will also be used for comparative analysis to evaluate the impact of market fluctuations on material costs and generate the market price fluctuation analysis result.

For each simulation i, collect the cost data X i 、the market price index P i 、the supply chain delay index S i and the risk assessment coefficient R i , calculate the weighted cost X of each simulation according to the formula i +αP i +βS i +γR i , calculate the average value of all simulation results to obtain the estimated value E(X) of the expected cost. The determination method of the weight coefficients is to perform a regression analysis through historical data to determine the influence intensity of each factor on the cost and assign the corresponding coefficient values.
