Description

Technical Field

[0001] The present invention relates to the field of building cost analysis, and in particular to a building prefabricated integrated module cost analysis method based on cloud computing. Background Art

[0002] Cast-in-place construction methods have problems such as waste of resources and long construction period. Using prefabricated parts for construction is an important way to shorten the construction period. This type of building is generally called prefabricated building.

[0003] Traditional prefabricated buildings only produce prefabricated parts in factories. During use, operators need to redesign and combine them according to the actual construction situation. During the design process, operators may make mistakes, resulting in insufficient, excessive, and mismatched components, which increases the cost of construction. How to improve construction efficiency and reduce construction costs through innovative methods has become the focus of the construction industry.

[0004] Building assembly integrated module is an advanced construction method, which prefabricates and assembles building components in the factory and then assembles them on site, thus realizing the industrialization, standardization and intelligence of the construction process. Building assembly integrated module greatly reduces the on-site construction time and the additional costs caused during the construction process by prefabricating building integrated modules in the factory.

[0005] Cloud computing is a distributed computing model based on the Internet. It refers to dividing huge data into many small modules through the network, and sending these small modules to a system composed of multiple computing devices for processing and analysis before returning the results. It provides computing resources, storage resources and applications to users through the network, realizing the ability to obtain and use computing resources on demand.

[0006] The cost analysis of traditional construction projects requires expensive computing equipment with powerful computing power, and local computing equipment is prone to being idle for a long time, which undoubtedly greatly increases the initial investment cost of cost analysis. With cloud computing, computing resources can be purchased on demand to reduce the cost of the project. Cost analysis also needs to consider unexpected factors during the construction process, such as insufficient materials extending the construction period, and excessive material reservations causing waste. The use of building prefabricated integrated modules can solve these problems while the integrated modules are still in the factory production process, avoiding problems during the construction process that cause overall project delays and increased costs.

[0007] Therefore, we urgently need to provide a cost analysis method for building prefabricated integrated modules based on cloud computing. Summary of the invention

[0063] The project information of the initial building prefabricated integrated module includes the demand information, production quantity, installation location, preset production time, preset maintenance cycle and preset service life of the initial building prefabricated integrated module;

[0064] The life cycle cost model of building prefabricated integrated modules is a comprehensive calculation framework that covers the costs of each life cycle stage;

[0065] The life cycle cost model includes the project life cycle decomposition layer, data processing layer and cost analysis layer;

[0066] The project life cycle decomposition layer is used to match the life cycle phase of the initial building assembly integration module according to the project information of the initial building assembly integration module;

[0067] The data processing layer is used to match the cost elements corresponding to the initial building prefabricated integrated modules according to the project information of the initial building prefabricated integrated modules, collect the cost data of each life cycle stage according to the cost elements corresponding to the initial building prefabricated integrated modules, pre-process the cost data of each life cycle stage of the building prefabricated integrated modules, and obtain the cost data of the life cycle stage to be calculated;

[0068] Cost elements are derived from a combination of historical data, market research, and expert judgment;

[0069] The cost analysis layer is used to calculate the initial integrated module cost of the initial building prefabricated integrated module life cycle using the life cycle cost data to be calculated. The initial integrated module cost includes the cost of each stage and the overall cost.

[0070] Establish a life cycle cost model, specific steps:

[0071] B1. Determine the life cycle stages of the building assembly integrated module. The complete life cycle stages of the building assembly integrated module include the production material stage, production component stage, production process stage, installation stage, maintenance stage and depreciation stage;

[0072] B2. Determine the cost elements of each life cycle stage. The cost elements of the production material stage include material costs and material transportation costs; the cost elements of the production component stage are component costs; the cost elements of the production process stage include production labor costs and equipment loss costs; the cost elements of the installation stage include installation labor costs and installation transportation costs; the cost elements of the maintenance stage include daily maintenance costs and damage repair costs; the cost elements of the depreciation stage are depreciation costs after use;

[0073] B3. The cost data of the production material stage is recorded as C a , C a =x a +y a , x a is the material cost of the integrated module frame, which is obtained by calculating the frame area of ​​the integrated module and the material cost per unit area. a Cost of transporting materials to the production site; do not choose only low-cost materials, but also consider the strength performance indicators of different types of materials; and plan the stage of replacing different materials according to the stage cost of production materials and the strength performance indicators of materials;

[0074] Cost data for the production component stage is recorded in C b , C b The total cost of purchasing or producing components is calculated by summing up the cost of each component. Components can be purchased or produced. The purchase cost is lower when the demand is small, and the production cost is lower when the demand is large. The purchase or production of different components is adjusted according to the demand for the components.

[0075] The cost data of the production process stage is recorded as C c , C c =(x c +y c )*d 1 , d 1 Default production time, x c is the average daily production labor cost, y cThe daily average equipment loss fee is different. The production time under different equipment is different, and the corresponding daily average equipment loss fee is also different. The effect of lowering production costs within the expected construction period can be achieved by adjusting the use of different equipment.

[0076] The cost data of the installation phase is recorded as C d , C d =x d +y d , x d For installation labor costs, y d For installation and transportation costs, during the installation phase, you can choose whether to outsource the installation or send someone to the installation site for installation based on the installation and transportation costs and installation labor costs at different distances from the installation site. If the installation site is far away, the installation labor costs of sending someone to install will be very high, so it is better to choose to outsource the installation at the installation site.

[0077] The cost data of the maintenance phase is recorded as C e , C e =(d 2 / T)*x d +K,d 2 is the preset service life, T is the preset maintenance period, x d is the maintenance cost of each maintenance, K is the expected damage repair cost; if the maintenance cycle is adjusted, the corresponding expected damage repair cost will increase as the maintenance cycle becomes longer, and adjusting the appropriate maintenance cycle can reduce the maintenance cost;

[0078] The cost of the depreciation stage is recorded as C f , C f =α*μ*M, α is the value loss ratio when the integrated module is no longer used, μ is the ratio of the currency when the integrated module is no longer used to the currency when the integrated module was built, and M is the total initial cost of depreciable materials; the main impact of the depreciation stage cost is the preset service life, the type of production integrated module frame and the type of components; the higher the depreciation stage cost, the lower the overall cost of the project, and changes in the production material stage will affect the depreciation stage cost;

[0079] B4. Collect verification data of several building prefabricated integrated modules, which include project information and costs of each stage of the building prefabricated integrated modules. Input the project information of the building prefabricated integrated modules into the initial life cycle cost model for verification, and adjust the parameters for calculating the cost data of each life cycle stage based on the cost of each stage;

[0080] S3. Use the value engineering (VE) analysis method in the cloud platform to analyze the function, performance and cost of the building prefabricated integrated module, cut unnecessary costs, improve efficiency and quality, achieve the purpose of cost control, and obtain the first optimized integrated module; send the first optimized integrated module to the life cycle cost model again to calculate the cost of the building prefabricated integrated module, and obtain the cost of the first optimized integrated module;

[0081] The life cycle stages of a complete building assembly integrated module include the production material stage, the production component stage, the production process stage, the installation stage, the maintenance stage, and the depreciation stage. If the project information of the given building assembly integrated module is missing, the stage cost corresponding to the missing project information is set to 0;

[0082] Value engineering is a systematic approach that aims to achieve the required quality, performance and reliability at the lowest overall cost by improving the functionality of products, services or processes. In the construction field, value engineering is widely used in the design, construction and operation phases of projects to ensure the highest value is provided within the budget.

[0083] Use the value engineering analysis method to analyze the demand information and integrated module cost of the initial building assembly integrated module. The specific steps are:

[0084] C1. Obtain the demand information, cost of each stage and overall cost of the initial building assembly integrated module;

[0085] C2. Check the standard stage cost ratio corresponding to the preset price level of the total cost of the initial building prefabricated integrated module; calculate the ratio of each stage cost to the total cost, and calculate the difference between the cost ratio of each stage and the standard stage cost ratio; if the difference exceeds the set range, replace the stage plan in the stage plan library for the corresponding stage;

[0086] The stage solution library stores different stage solutions for different stages. When the cost of production materials is too high, you can search for different stage solutions for production materials in the stage solution library. The cost of production materials is generally determined by the type of materials. Under the condition that the material grade is not lower than the set material grade, choose cheaper materials to reduce the problem of too high cost of production materials.

[0087] The preset price levels are given by professionals, and the corresponding standard stage costs can be obtained from historical data or set by professionals;

[0088] If the project information of the initial building prefabricated integrated module is missing, the missing items need to be cut and the remaining life cycle stages need to be re-divided into stage cost ratios;

[0089] C3. Check the functional requirements and performance requirements in the initial building prefabricated integrated module demand information, and label the performance of each function according to the preset standard performance level table; calculate the average value of the performance levels of all functions as the average performance level, calculate the difference between the performance level of each function and the average performance level, and if the difference exceeds the set ratio, optimize the performance level of the corresponding function;

[0090] The performance level label is obtained by dividing the performance level corresponding to the function according to a certain ratio. When optimizing the performance level, the lowest performance level must be considered, which cannot be lower than the performance requirements in the building assembly integrated module demand information;

[0091] C4. Output the optimized solution as an optimization integrated module; output the operation of changing the phase solution and optimizing the performance level as analysis optimization suggestions;

[0092] S4. Calculate the absolute value Ja and the cost reduction rate Jb of the optimized integrated module cost compared to the initial integrated module cost, analyze the values ​​of the absolute value Ja and the cost reduction rate Jb, and obtain a loop instruction; determine whether to loop the S3 process according to the loop instruction;

[0093] The cost of the building assembly integrated module is recorded as C n The cost of the prefabricated integrated module is recorded as C 0 , the cost of the first optimized integrated module is recorded as C 1 , record the cost of each optimized integrated module in turn;

[0094] The total cost of the initial building assembly integrated module is recorded as C 0 , the total cost of the optimized integrated module obtained by the first optimization is recorded as C 1 , record the total cost C of each optimized integrated module in turn n ;

[0095] Calculate the absolute value of cost reduction J a =|C n -C n-1 |, calculate the reduction rate J b =(1-C n / C n-1 )*100%;

[0096] Compare the absolute value of cost reduction J a and cost reduction rate J b Is it greater than the set value? If the cost is reduced by an absolute value J a and cost reduction rate J b If there is a value greater than the set value, the loop instruction is output to start the loop, otherwise the loop stop instruction is output;

[0097] The set value needs to be set according to the actual situation. A smaller set value can analyze more optimized integrated modules, but if the set value is too small, the calculation cost will increase and error optimization will easily occur; the absolute value of cost reduction J a When the total cost is large, it is more useful than the cost reduction rate. If the total cost is not large, the set value can be set to infinity.

[0098] S5. The cloud platform collects all the integrated module costs and cost optimization suggestions in the processes of S2, S3 and S4 as result visualization data, visualizes the result visualization data, and outputs the visualization results to the user end;

[0099] Visualize the result data. Specific steps:

[0100] The visualization results include a cost line graph and a cost data table. The line graph includes a line graph of the overall cost of the integrated module and a line graph of the cost of each stage of the integrated module.

[0101] Calculate the cost difference and difference ratio of each stage in the upper and lower rows of the cost data table, and output them after the cost of each stage in each row of the table; these two data are part of the cost analysis results;

[0102] The cost analysis results include the life cycle costs and overall costs of the building assembly integrated modules, the absolute value and cost reduction rate of the optimized integrated modules compared with the original integrated modules;

[0103] By associating the line graph with the table, users can observe the areas with large cost changes through the line graph and click to jump to the cost analysis results and cost optimization suggestions corresponding to the associated table; through the visualization results, the cost analysis results and cost optimization suggestions of the building prefabricated integrated modules can be quickly obtained, which is convenient for selecting the optimal integrated module among multiple optimized integrated modules.
