[0047] See also Figure 1 , which is a flow chart of the real-time analysis and management method for construction cost of the first embodiment of the present application, including:
[0048] S1: extracting information from the engineering cost reference file to obtain multiple engineering projects in the engineering cost reference file and reference costs corresponding to each engineering project;
[0049] S2: extracting information from the construction cost files uploaded by each construction unit according to the multiple construction projects to obtain the project cost of each construction cost file corresponding to each of the construction projects;
[0050] Among them, information extraction can be achieved through table text and number recognition to identify multiple engineering projects and the corresponding costs of each engineering project.
[0051] S3: Based on a first cost difference between the reference cost and the project cost corresponding to the same engineering project, taking the project cost corresponding to the first cost difference greater than a preset cost difference threshold as an identified cost;
[0052] S4: Obtaining a cost average according to the project costs of the engineering projects corresponding to the identified costs;
[0053] S5: Determine the cost attribute of the marked cost according to the cost mean and the second cost difference of the marked cost.
[0054] In a feasible embodiment, the step of obtaining the average cost according to the project costs of the engineering projects corresponding to the identified costs in S4 includes:
[0055] S41: Obtaining a maximum exclusion quantity range based on the quantity of the engineering cost document;
[0056] S42: randomly obtaining a maximum exclusion number from the maximum exclusion number range;
[0057] S43: excluding, based on the maximum exclusion number, several maximum project costs and several minimum project costs of the plurality of project costs corresponding to the identified cost, to obtain a plurality of remaining project costs to be processed; the number of excluded project costs is equal to the maximum exclusion number;
[0058] S44: Calculate the average cost of the multiple pending projects to obtain the average cost.
[0059] Among them, mean calculation refers to summing up the costs of multiple pending projects and then calculating the average.
[0060] In a feasible embodiment, the step of S5: determining the cost attribute of the marked cost according to the cost mean and the second cost difference of the marked cost, includes:
[0061] S51: If the difference between the cost average and the second cost of the marked cost is greater than the preset difference threshold, determine that the marked cost is an abnormal cost.
[0062] In a feasible embodiment, the step of S5: determining the cost attribute of the marked cost according to the cost mean and the second cost difference of the marked cost, includes:
[0063] S52: If the difference between the average cost and the second cost of the marked cost is less than or equal to the preset difference threshold, determine that the marked cost is a valid cost.
[0064] This application obtains the reference price corresponding to each engineering project in the engineering cost reference file, as well as the project price of each engineering project in the engineering cost file uploaded by each construction unit. Then, based on the first price difference between the reference price and the project price, the project price corresponding to the first price difference greater than the preset difference threshold is used as the identification price. Then, based on the various project costs of the engineering project corresponding to the identification price, the average price is obtained. Then, based on the second price difference between the average price and the identification price, the cost attribute of the identification price is determined. The project cost of the engineering cost file uploaded by the construction unit can be analyzed to determine the cost attribute of the identification price, thereby determining whether the identification price is valid or abnormal. The project cost of the engineering cost file can be analyzed efficiently and accurately, and labor costs can also be saved.
[0065] In a feasible embodiment, after the step of determining that the marked cost is a valid cost if the difference between the average cost and the second cost of the marked cost is less than or equal to the preset difference threshold in S52, the step further includes:
[0066] S521: Update the reference cost of the project according to the average cost of the project corresponding to the effective cost.
[0067] In this embodiment, it is taken into account that the reference cost may be a cost value obtained based on historical data, but as the market develops, the value of construction materials and labor will change. The project cost of the project combined with the construction cost files uploaded by multiple construction units can reflect the changes in the cost value. Therefore, when the marked cost is a valid cost, the reference cost of the project should also be updated according to the average cost of multiple construction cost files to prevent the reference cost of the project from being too far away from the market situation.
