[0002] As the scale and complexity of construction projects continue to expand, the importance of construction cost management has become increasingly prominent. The goal of construction cost management is to reasonably control and optimize construction costs and maximize investment benefits while ensuring project quality.

[0003] At present, the cost management of construction projects mainly adopts a phased management model. Managers regularly collect actual cost data for comparison and analysis during the construction process of each construction stage, and take corresponding adjustment measures when it is found that the cost exceeds expectations. However, since engineering projects often face many unforeseen situations during the actual construction process, such as market fluctuations in raw material prices and labor costs, the cost will deviate from the budget. These factors are often sudden and uncertain. The traditional management model is difficult to detect and adjust in time when dealing with these complex situations, resulting in poor overall management of construction projects.

[0022] The following will provide a clear and complete description of the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0023] Please refer to Figure 1 , a flow chart of a method for dynamic management of the whole process of construction cost is proposed. The method can be implemented by a computer program, can be implemented by a single-chip microcomputer, and can also be run on a dynamic management system for the whole process of construction cost. The computer program can be integrated in a computer device, or can be run as an independent tool application. Specifically, the method includes steps 10 to 40, and the above steps are as follows: Step 10: Determine the target sub-plan corresponding to the current stage of the construction project. The construction project includes multiple stages, and each stage corresponds to a sub-plan.

[0024] In the embodiment of the present application, a construction project refers to a construction project that requires cost management. The construction project is divided into multiple continuous construction stages from start to completion, including but not limited to the foundation engineering stage, the main structure construction stage, the decoration engineering stage, etc. Each stage has relatively independent construction content and cost targets.

[0025] The current stage in this application embodiment refers to a specific stage in which a construction project is under construction. This stage has clear construction drawings, technical requirements and cost control objectives, and is the target stage for real-time cost management and monitoring.

[0026] In the present application, the target sub-plan refers to a cost control plan formulated for the current stage of a construction project, which includes the cost data of the sub-projects at that stage, the cost control benchmark, etc. The target sub-plan is a cost control plan formulated based on factors such as the characteristics of the engineering components, the construction process requirements, the engineering quantity, and the current market price, combined with the engineering cost quota standard.

[0027] Specifically, in the process of implementing construction projects, in order to achieve accurate cost control, it is necessary to first clarify the specific stage of the current construction and its corresponding target sub-plan. Since construction projects usually have a long span, there are significant differences in the construction content and cost characteristics of different stages. Therefore, the entire project is divided into multiple stages and sub-plans are formulated separately. When determining the target sub-plan corresponding to the current stage, it is first necessary to obtain the construction drawings and technical requirements of the current stage, and extract the characteristics of the engineering components and the construction process requirements from them. For example, in the main structure construction stage, it is necessary to analyze the size specifications of the structural components, the steel bar configuration requirements, the concrete strength grade and other characteristics, as well as the process requirements such as formwork support, steel bar binding, and concrete pouring. Based on these characteristics and requirements, the engineering quantity of the current stage can be accurately calculated, such as the concrete volume and steel bar usage. Subsequently, combined with the price information of various materials, labor, and machinery in the current market, the cost data of each sub-project in the current stage are calculated. At the same time, it is necessary to refer to the engineering cost quota standard and combine the specific implementation conditions of the project, such as construction site conditions and climate characteristics, to determine the cost control benchmark. Finally, the sub-project costs and cost control benchmarks are integrated to form the target sub-plan for the current stage.

[0028] Based on the above embodiment, as an optional embodiment, the step of determining the target sub-plan corresponding to the current stage of the construction project may further include the following steps: Step 101: Obtain the construction drawings and technical requirements of the current stage, and extract the characteristics of engineering components and construction process requirements.

[0029] Specifically, construction drawings include engineering drawings such as architectural plans, structural details, and equipment layout drawings, while technical requirements include technical documents such as construction specifications, quality standards, and acceptance procedures. After obtaining construction drawings and technical requirements, it is necessary to focus on extracting engineering component features and construction process requirements. Taking the main structure construction stage as an example, the characteristics of engineering components include geometric parameters such as the length, height, and thickness of the wall, the span and thickness of the floor slab, the cross-sectional size and height of the column, and material parameters such as concrete strength grade and steel bar model. Construction process requirements include technical regulations for specific construction links such as formwork support methods, steel bar binding requirements, concrete pouring technology, and maintenance requirements. Identify the component types and basic dimensions in the construction drawings. Management personnel can also check and supplement the identification results according to the construction process requirements to ensure that the extracted feature data is accurate and complete. For example, for the construction of concrete structures, it is necessary to consider the concrete strength requirements of different components and factors such as material loss that may occur during the construction process.

[0030] Step 102: Determine the engineering quantity of the current stage according to the characteristics of the engineering components and the construction process requirements.

[0031] Specifically, the corresponding calculation rules can be used for different types of components to calculate the current stage of the project quantity. For example, the volume of concrete is calculated according to the geometric dimensions of the component, and the construction loss coefficient is taken into account; the amount of steel bars needs to be calculated based on the reinforcement ratio and component size, and then the actual amount is determined in combination with the construction process requirements. In this way, a detailed bill of quantities including earth excavation volume, concrete volume, steel bar usage, formwork area, etc. can be obtained.

[0032] Step 103: Based on the project quantity and current market price, calculate the construction cost of the sub-projects at the current stage.

[0033] Specifically, it is necessary to obtain the price information of materials, labor and machinery in the current market. Taking the main structure construction stage as an example, it is necessary to collect market quotations of main materials such as steel bars, concrete, and formwork, as well as labor cost standards for construction personnel such as carpenters, steel workers, and concrete workers. At the same time, the rental or use costs of large machinery such as tower cranes and concrete pump trucks must also be considered. In order to ensure the accuracy of price information, price data can be obtained through various channels such as building materials market research, price comparison, and historical data analysis. After obtaining the price information, it is combined with the aforementioned determined engineering quantity data to calculate the cost of each sub-project. The characteristics of different sub-projects need to be considered during the calculation process. For example, the cost calculation of the concrete sub-project needs to include multiple components such as material costs, labor costs, machinery costs, and transportation costs. In this way, a detailed sub-project cost list including foundation engineering, main structure, and decoration engineering can be obtained.

[0034] Step 104: Determine the cost control benchmark for the current stage based on the engineering cost quota standards and implementation conditions.

[0035] Specifically, when determining the cost control benchmark, it is necessary to refer to the engineering cost quota standards and make reasonable adjustments based on the specific implementation conditions of the project. The engineering cost quota standards usually include the consumption quotas of labor, materials, machinery, etc. for various sub-projects, as well as the corresponding pricing methods. When using these standards, it is necessary to consider the construction environment characteristics of the project location, such as the impact of factors such as climate conditions, site conditions, and traffic conditions on the cost. For example, when constructing in cold areas, it is necessary to consider the cost of cold-proof and heat-insulating measures; when constructing in areas with inconvenient transportation, it is necessary to consider the increase in material transportation costs.

[0036] Step 105: Integrate the sub-project costs and cost control benchmarks into the target sub-plan for the current stage.

[0037] Specifically, the calculated sub-project costs and the determined cost control benchmark will be integrated to form the target sub-plan for the current stage.

[0038] Step 20: Determine the key cost indicators associated with the current stage based on the target sub-plan.

[0039] In the embodiment of the present application, key cost indicators refer to core monitoring data that have an important impact on the cost of a construction project, including but not limited to the unit price of main materials, the unit price of labor costs, the unit price of machinery usage fees, the comprehensive unit price of sub-projects, etc.

[0040] Specifically, analyze the cost composition of each sub-project at the current stage and its proportion in the total cost. Taking the main structure construction stage as an example, by analyzing the cost data of the sub-projects in the target sub-plan, it can be found that the cost of concrete engineering and steel engineering usually accounts for a large proportion. Therefore, the cost indicators such as the unit price of materials and the unit price of labor costs in these two sub-projects need to be focused on as key cost indicators. Secondly, it is necessary to consider the factors that are prone to price fluctuations or changes in market supply and demand during the construction process. For example, the cost of using large-scale machinery and equipment may fluctuate with changes in market demand, so the unit price of the use fee of major machinery such as tower cranes and concrete pump trucks should also be included in the scope of key cost indicators. At the same time, for some materials or cost items that have a low cost ratio but large price fluctuations, such as templates and their turnover costs, their related indicators also need to be determined as key cost indicators. In the process of determining these key cost indicators, it is also possible to identify the projects and links that are most likely to have cost anomalies in different stages through statistical analysis of historical project data, so as to determine the key cost indicators in a targeted manner.

[0041] Based on the above embodiment, as an optional embodiment, the step of determining the key cost indicators associated with the current stage based on the target sub-plan may further include the following steps: Step 201: Extract the sub-project cost data in the target sub-plan.

[0042] Specifically, the project content of the current stage is classified and sorted according to the construction process and pricing characteristics. Taking the main structure construction stage as an example, the project content can be divided into sub-projects such as concrete engineering, steel engineering, and formwork engineering. The cost data of each sub-project is extracted, including the total cost of the sub-project, the comprehensive unit price, and various cost components. During the extraction process, the cost management software can be used to analyze the target sub-plan data and automatically generate a cost data list for each sub-project.

[0043] Step 202: Determine cost components based on the sub-project cost data.

[0044] Specifically, the cost of each sub-project is decomposed to identify its main components. For example, for concrete engineering, its cost components include concrete material costs, pouring labor costs, pumping machinery costs, etc.; for steel bar engineering, it includes steel bar material costs, processing costs, installation labor costs, etc. Through this decomposition analysis, the internal structure of the cost of each sub-project can be clearly displayed, and the proportion of different elements in the total cost can be calculated.

[0045] Step 203: Determine key monitoring items based on cost components.

[0046] Specifically, when determining key monitoring items, it is necessary to comprehensively consider the importance and risk of changes of the cost components. First, determine the main monitoring objects based on the proportion of the cost. For example, when it is found that the steel bar material cost accounts for a large proportion of the total cost, it should be listed as a key monitoring item. Secondly, considering market fluctuations, even if the cost of certain elements does not account for a high proportion, if their prices fluctuate frequently or the amplitude is large, they also need to be included in the key monitoring scope. For example, the wages of professional construction workers may change greatly with the market supply and demand relationship, so the relevant labor costs should also be a key monitoring item.

[0047] Step 204: Set the target value and warning value of each key monitoring item.

[0048] Specifically, when setting the target cost, it is necessary to use the cost data in the target sub-plan as a benchmark and make a reasonable determination based on the market price trend and the actual situation of the project. Taking the steel bar project as an example, the setting of its target cost needs to consider multiple factors such as the fluctuation pattern of steel market prices, regional differences in transportation costs, and construction process requirements. Specifically, the target unit price of steel bar materials can be determined by analyzing historical price data and combining market forecast reports; the target unit price of steel bar workers' wages can be determined by investigating the local labor market; and the target usage fee of steel bar processing equipment can be determined by measuring the efficiency of machinery use. These specific indicators together constitute the target cost system of steel bar projects.

[0049] The setting of the warning value needs to consider the acceptable range of cost fluctuations on the basis of the target construction value. Usually, the upper and lower limits are set, that is, a reasonable fluctuation range is determined based on the target construction value. The determination of this range needs to consider the characteristics of different monitoring projects. For example, for concrete materials with relatively stable prices, the warning value can be set within the range of ±5% of the target construction value; while for steel materials with large price fluctuations, the warning value range may need to be expanded to ±10%. At the same time, the setting of the warning value also needs to consider the cost control requirements and risk tolerance of the project, while ensuring the cost control effect, avoiding too frequent warnings that interfere with normal construction.

[0050] Step 205: Determine the target cost value and warning value of each key monitoring project as key cost indicators.

[0051] Specifically, the set target cost values ​​and warning values ​​are determined as key cost indicators, and a complete indicator system is established. This system includes elements such as indicator name, measurement unit, target value, warning upper limit value, warning lower limit value, etc.

[0052] Step 30: Obtain the actual cost data of the current stage, and determine abnormal indicators with cost deviations based on the actual cost data and key cost indicators.

[0053] The actual cost data in the embodiment of the present application refers to the actual cost information obtained through on-site statistics, records and calculations during the construction process of the building project, including the actual material purchase price, the actual labor costs incurred, the actual machinery usage fees paid, and the actual completed cost of the sub-project calculated therefrom.

[0054] In the embodiment of the present application, the abnormal indicator refers to a cost indicator that exceeds the allowable deviation range by comparing the actual cost data with the cost control benchmark set in the target sub-plan.

[0055] Specifically, the cost management information system is used to collect the actual cost data of the current stage. For example, by connecting with the material management system, the actual purchase price of the material is automatically obtained; by connecting with the labor management system, the labor cost expenditure is automatically counted; by connecting with the mechanical equipment management system, the equipment usage fee is automatically recorded. Based on the actual cost data obtained, it is necessary to conduct a systematic comparison with the key cost indicators determined in the early stage to identify abnormal indicators. During the comparison process, the actual cost data is first compared with the target value of the key cost indicator, and the deviation value is calculated; then the deviation value is compared with the warning value to determine whether it exceeds the allowable range. For example, when it is found that the actual purchase price of a certain steel exceeds the warning upper limit, or a certain labor cost is lower than the warning lower limit, it can be determined as an abnormal indicator.

[0056] Based on the above embodiment, as an optional embodiment, the step of determining abnormal indicators with cost deviation based on actual cost data and key cost indicators may further include the following steps: Step 301: extracting the actual cost data and actual engineering quantity of each key monitoring project.

[0057] Specifically, a multi-source data collection mechanism is established. The actual cost data is collected mainly through financial vouchers such as project settlement sheets, material purchase orders, and labor cost settlement sheets. For example, for steel bar projects, it is necessary to collect cost vouchers such as steel bar purchase invoices, transportation cost documents, and processing cost settlement sheets. The actual project quantity is collected mainly through technical data such as construction logs, project acceptance records, and on-site measurement data. For example, it is necessary to count the specific project quantity data such as the completed steel bar processing and installation volume and the concrete pouring volume.

[0058] Step 302: Obtain the target cost value and target engineering quantity of each key monitoring project from the key cost indicators.

[0059] Specifically, when obtaining target data from key cost indicators, it is necessary to combine the target sub-plan for systematic extraction. The acquisition of target construction value is mainly based on the key cost indicator system determined in the early stage, including the unit price indicator and total price indicator of each monitoring project. The acquisition of target engineering quantity requires extracting the planned engineering quantity of each sub-project based on the construction plan and technical plan.

[0060] Step 303: Calculate the cost deviation rate between the actual cost data and the target cost data, and the engineering quantity deviation rate between the actual engineering quantity and the target engineering quantity.

[0061] Specifically, when calculating the deviation rate between the actual cost data and the target cost, a standardized calculation formula is used: cost deviation rate = (actual cost data - target cost) / target cost × 100%. For example, for a steel bar project, if the actual cost is 5.8 million yuan and the target cost is 5 million yuan, the cost deviation rate is 16%, indicating that the project cost exceeds expectations. Similarly, when calculating the deviation rate between the actual engineering quantity and the target engineering quantity, a similar calculation method is used: engineering quantity deviation rate = (actual engineering quantity - target engineering quantity) / target engineering quantity × 100%.

[0062] Step 304: Calculate a comprehensive deviation value based on the cost deviation rate and the engineering quantity deviation rate.

[0063] Specifically, after obtaining the cost deviation rate and the engineering quantity deviation rate, it is necessary to obtain a comprehensive deviation value that can reflect the overall deviation status through comprehensive calculation. The calculation formula is: comprehensive deviation value = α × cost deviation rate + β × engineering quantity deviation rate, where α and β are weight coefficients, and α + β = 1. The determination of the weight coefficient needs to consider the characteristics and importance of different monitoring items. For example, for material-consuming engineering projects, α = 0.6 and β = 0.4 can be set to reflect the importance of cost changes; for labor-intensive engineering projects, α = 0.4 and β = 0.6 can be set to highlight the impact of engineering quantity changes.

[0064] Step 305: Compare the comprehensive deviation value with the corresponding warning value, and determine that the key monitoring items exceeding the warning value are abnormal indicators.

[0065] Specifically, by comparing the calculated comprehensive deviation value with the pre-set warning value, abnormal indicators can be accurately identified. When the comprehensive deviation value exceeds the warning value range, the monitored item can be determined as an abnormal indicator. For example, if the warning value of a certain item is set to ±15%, when the calculated comprehensive deviation value is 18%, it means that the item has exceeded the acceptable fluctuation range and needs to be focused on as an abnormal indicator.

[0066] Step 40: Adjust the sub-plans corresponding to each stage in the construction project based on the abnormal indicators to obtain new sub-plans corresponding to each stage.

[0067] Specifically, when adjusting the sub-plan, it is necessary to first analyze the specific reasons for the abnormal indicators. Through in-depth analysis of the cost deviation rate and the engineering quantity deviation rate, combined with the actual situation of the project, identify the key factors causing the abnormality. For example, when it is found that the abnormal indicators of the steel bar project are caused by market price fluctuations, it is necessary to focus on adjusting the material procurement plan; when it is found that the abnormality of the concrete project is caused by changes in the construction plan, it is necessary to focus on adjusting the construction organization plan. The adjustment of the sub-plan needs to follow the principle of systematicity, considering both the adjustment needs of the current stage and the impact on the subsequent stages. For the sub-plans at the current stage, the focus is on correcting the deviations that have occurred by adjusting the specific implementation plan. For example, if it is found that the labor cost of a sub-project is seriously overspent, the labor cost can be reduced by optimizing the construction process, improving the operation method and other measures. For the sub-plans in the subsequent stages, it is necessary to adjust the relevant parameters and control measures in advance through pre-judgment analysis to prevent similar problems from occurring. In the specific adjustment process, the step-by-step adjustment method is adopted. First, adjust the directly related sub-plans, such as adjusting the material procurement plan, modifying the construction plan, etc. Then, according to the association relationship, make corresponding adjustments to the indirectly related sub-plans, such as adjusting the capital payment plan, updating the progress plan, etc. This step-by-step adjustment method can ensure that each sub-plan is coordinated and consistent.

[0068] Based on the above embodiment, as an optional embodiment, the step of adjusting the sub-plans corresponding to each stage in the construction project based on the abnormal indicators to obtain new sub-plans corresponding to each stage may also include the following steps: Step 401: Calculate the impact of the abnormal indicator, and determine whether adjusting the sub-plan at the current stage can eliminate the impact of the abnormal indicator based on the impact.

[0069] Specifically, when calculating the impact of abnormal indicators, a comprehensive evaluation method is adopted: impact = γ × cost impact coefficient + δ × duration impact coefficient + ε × quality impact coefficient, where γ, δ, ε are weight coefficients, and γ + δ + ε = 1. The cost impact coefficient reflects the impact of abnormal indicators on the total cost of the project, the duration impact coefficient reflects the impact on the project progress, and the quality impact coefficient represents the impact on the project quality. For example, when an abnormality occurs in a steel bar project, if its cost impact coefficient is 0.3, the duration impact coefficient is 0.2, and the quality impact coefficient is 0.1, and the weight coefficients γ = 0.5, δ = 0.3, and ε = 0.2 are set, the impact of the abnormal indicator can be calculated to be 0.23. Based on the calculated impact, combined with the pre-set impact threshold, it is judged whether the adjustment of the sub-plan at the current stage is sufficient to eliminate the impact of the abnormal indicator. For example, if the impact threshold is set to 0.2, when the calculated impact exceeds the threshold, it indicates that only adjusting the sub-plan at the current stage may not completely eliminate the impact of the abnormal indicator, and it is necessary to consider expanding the adjustment range.

[0070] Step 402: If the sub-plan of the current stage cannot eliminate the influence of the abnormal index, then analyze the correlation between the abnormal index and each subsequent stage after the current stage.

[0071] Specifically, if the sub-plan of the current stage cannot eliminate the impact of abnormal indicators, it is necessary to expand the scope of adjustment, and analyze the correlation between abnormal indicators and subsequent stages. The calculation of correlation adopts the weighted scoring method: correlation = Σ(Wi×Fi), where Wi is the weight of each evaluation factor, and Fi is the score value of each factor. Evaluation factors include technical correlation, resource dependence, progress correlation, etc. For example, for abnormal indicators of concrete engineering, it is necessary to evaluate the degree of correlation with subsequent decoration engineering, equipment installation engineering and other stages. If the calculated correlation with the decoration engineering is 0.8 and the correlation with the equipment installation engineering is 0.3, it means that it is necessary to focus on the adjustment of the decoration engineering stage.

[0072] Step 403: Determine the stage range that needs to be adjusted based on the correlation.

[0073] Specifically, when determining the range of adjustment stages, the correlation threshold method is used, that is, when the correlation between a subsequent stage and the abnormal indicator exceeds the set threshold, the stage is included in the adjustment range. For example, if the correlation threshold is set to 0.5, then all stages with a correlation greater than 0.5 need to be adjusted accordingly. This method ensures that the adjustment range is neither too large to waste resources nor too small to cause insufficient regulation.

[0074] Based on the above embodiment, as an optional embodiment, the step of determining the stage range that needs to be adjusted based on the correlation degree may further include the following steps: Step 4031: Analyze the impact chain of abnormal indicators on subsequent stages after the current stage to obtain the initial impact coefficient of each subsequent stage.

[0075] Specifically, when analyzing the impact chain of abnormal indicators, we first need to build an impact transmission model. This model takes the abnormal indicators as the starting point and forms a complete impact network by sorting out the transmission paths of multiple dimensions such as technical associations, resource dependencies, and progress impacts. For example, when the cost of a steel bar project is abnormal, it is necessary to analyze its impact path on subsequent concrete projects, decoration projects, equipment installation projects, and other stages. This impact may be transmitted directly, such as the increase in steel bar prices directly affecting the cost of structural projects; it may also be transmitted indirectly, such as the delay of steel bar projects leading to the compression of subsequent process time, which in turn affects construction costs.

[0076] When calculating the initial impact coefficients of each subsequent stage, a multi-factor evaluation method is used: initial impact coefficient = λ1×technical impact factor + λ2×resource impact factor + λ3×schedule impact factor, where λ1, λ2, and λ3 are weight coefficients, and λ1+λ2+λ3=1. The value range of each impact factor is 0-1, which is determined by expert evaluation or historical data analysis. For example, if the technical impact factor of the abnormal steel bar engineering on the concrete engineering is 0.8, the resource impact factor is 0.6, and the schedule impact factor is 0.7, and the weight coefficients are 0.4, 0.3, and 0.3 respectively, then the initial impact coefficient of the concrete engineering can be calculated to be 0.71.

[0077] Step 4032: Based on the initial influence coefficient, calculate the influence transfer strength between each subsequent stage.

[0078] Specifically, after obtaining the initial impact coefficient of each subsequent stage, it is necessary to calculate the impact transfer strength between stages. The calculation of transfer strength adopts the attenuation model: transfer strength = initial impact coefficient × attenuation coefficient K, where the attenuation coefficient K is related to the distance and degree of association between stages. For example, if there is a direct correlation between two stages, the K value may be close to 1; if the degree of association is weak, the K value will decrease accordingly. This attenuation model can reflect the weakening characteristics of the cost impact during the transmission process.

[0079] Step 4033: According to the impact transfer intensity, determine the key stages affected in each subsequent stage and their cumulative impact values.

[0080] Specifically, the cumulative impact value of each subsequent stage should be calculated based on the impact transmission intensity. The cumulative impact value is calculated using the weighted accumulation method: cumulative impact value = Σ(αi×Si), where αi is the weight coefficient of each transmission path, and Si is the corresponding transmission intensity. For example, a certain stage is affected through three different paths, with transmission intensities of 0.6, 0.4, and 0.3, respectively, and corresponding weights of 0.4, 0.35, and 0.25. The cumulative impact value of this stage is 0.445. This calculation method takes into account the superposition effect of multi-path impacts and can more accurately reflect the actual degree of impact.

[0081] Step 4034: Determine the comprehensive impact level of each key stage based on the cumulative impact value.

[0082] Specifically, based on the cumulative impact value and combined with the stage characteristic index, the comprehensive impact degree of each stage can be calculated. The calculation adopts the extreme value comparison method: comprehensive impact degree = Max (cumulative impact value, characteristic index). The characteristic index mainly considers factors such as the proportion of stage cost, criticality of construction period, and quality sensitivity, and takes the maximum value as the characteristic index. For example, if the cumulative impact value of a certain stage is 0.6, the proportion of cost is 0.5, the criticality of construction period is 0.7, and the quality sensitivity is 0.4, then the characteristic index is 0.7, and the final comprehensive impact degree of this stage is 0.7.

[0083] Step 4035: Based on each key stage whose comprehensive impact degree exceeds the impact degree threshold, generate a stage range that needs to be adjusted.

[0084] Specifically, when determining the range of stages that need to be adjusted, a threshold judgment is used. The impact threshold θ is set in advance. When the comprehensive impact of a certain stage exceeds θ, the stage is included in the adjustment range. The setting of the impact threshold needs to consider factors such as project characteristics, management capabilities, and resource conditions. For example, if θ=0.5 is set, all stages with a comprehensive impact greater than 0.5 need to be adjusted. This method can avoid the problem of too large or too small adjustment range and ensure the pertinence and feasibility of the control measures.

[0085] Step 404: Determine new sub-plans that need to be adjusted for each subsequent stage in the stage range.

[0086] Specifically, when formulating a new sub-plan, it is necessary to first analyze the original plan parameters of each stage, including key elements such as planned duration, planned cost, and planned resource allocation. By comparing the original plan parameters with the comprehensive impact degree, the specific parameters that need to be adjusted can be determined. For example, when the comprehensive impact degree of a certain stage is 0.7, it indicates that the original plan parameters of this stage may need to be adjusted to a large extent. The formulation of the new sub-plan adopts the plan parameter correction method. For the duration adjustment, the time buffer value is determined based on the comprehensive impact degree. When the comprehensive impact degree exceeds the threshold, the buffer time is added to the original planned duration. In terms of resource allocation, a resource supplement strategy is adopted to determine the amount of resources to be supplemented based on the comprehensive impact degree. This strategy ensures the adequacy of resource supply. The cost adjustment adopts the cost correction method. The cost adjustment range is determined according to the comprehensive impact degree. For example, if the original planned cost of a certain stage is 1 million yuan and the comprehensive impact degree is 0.8, it is necessary to increase the cost budget by 800,000 yuan to make the new planned cost reach 1.8 million yuan.

[0087] Based on the above embodiment, as an optional embodiment, a method for dynamic management of the entire construction cost process may further include the following steps: Specifically, the adjustment range of the new sub-plan in each stage is calculated. The adjustment range is obtained by comparing the parameters of the new and old plans, and the calculation method is: adjustment range = (new plan parameters - original plan parameters) / original plan parameters. For example, if the original planned duration of a stage is 30 days and the new planned duration is 51 days, the adjustment range of the duration is 0.7; if the original planned cost is 1 million yuan and the new planned cost is 1.8 million yuan, the cost adjustment range is 0.8; the maximum value of the adjustment range of these parameters is taken as the overall adjustment range of the stage, which is 0.8 in this example. Based on the calculated adjustment range of each stage, an adjustment intensity distribution diagram is generated. The distribution diagram uses the project timeline as the horizontal axis and the adjustment range as the vertical axis, and draws the adjustment range of each stage into a curve. This visual display method can intuitively reflect the distribution characteristics of the adjustment intensity and facilitate the discovery of abnormal fluctuations. For example, if the adjustment range of a stage is significantly higher than that of the adjacent stage, an obvious peak will be formed on the distribution diagram. By analyzing the adjustment intensity distribution diagram, the stage nodes with abnormal adjustment ranges can be identified. Use the range analysis method to identify anomalies: calculate the difference in the adjustment range of adjacent stages, and when the difference exceeds the preset threshold, mark the node as an abnormal node. For example, set the threshold to 0.3, if the adjustment range of a certain stage is 0.8, and the adjacent stage is 0.4, the difference is 0.4, which is greater than the threshold, then the node is identified as an abnormal node.

[0088] For the identified abnormal nodes, constraints need to be established for secondary optimization. Constraints include smoothness constraints of the adjustment range of adjacent stages, resource capacity constraints, and overall cost constraints. Smoothness constraints require that the difference in the adjustment range of adjacent stages does not exceed the threshold; resource capacity constraints ensure that the adjusted resource demand does not exceed the upper limit of available resources; and overall cost constraints ensure that the total cost after optimization is within an acceptable range.

[0089] Based on these constraints, the interval balance method is used to perform secondary optimization on the new sub-plan. First, the adjustment interval of the abnormal node is determined, that is, the optimization interval is formed by taking the abnormal node as the center and extending forward and backward. In this interval, the adjustment range is smoothed by adjusting the planning parameters of each stage. For example, the adjustment range of an abnormal node is 0.8. By redistributing the adjustment amount in the optimization interval, the adjustment range of the node may be reduced to 0.6, while the adjustment range of the adjacent stages can be appropriately increased to achieve overall balance. For example, in a certain engineering project, by adjusting the intensity distribution map, it was found that the adjustment range of the decoration stage was abnormally high at 0.9, while the adjacent stage was only 0.4. After secondary optimization, the adjustment range of the decoration stage was reduced to 0.7, and the adjustment range of the adjacent stage was appropriately increased to 0.5, which not only ensured the necessary adjustment strength, but also avoided excessive local adjustments.
