Description

Technical Field

[0001] This invention belongs to the field of data processing technology, and in particular relates to a method and system for analyzing and processing construction investment consulting data. Background Technology

[0002] In the process of generating construction investment consulting reports, it is necessary to integrate historical investment projects to generate investment consulting reports, conduct investment estimations and design budgets. Therefore, how to manage investment consulting data of historical projects in order to improve the accuracy of investment estimation results of construction investment consulting data has become an urgent technical problem to be solved.

[0003] To estimate the construction volume of construction projects in investment consulting reports, it is often necessary to combine historical investment consulting projects in the database for evaluation. Therefore, how to determine the update plan for historical investment consulting projects based on the deviation of the estimation of construction volume for different construction projects, so as to ensure the reliability of the estimation of construction volume, has become an urgent technical problem to be solved.

[0004] To address the aforementioned technical problems, this application provides a method and system for analyzing and processing construction investment consulting data. Summary of the Invention

[0005] To achieve the objectives of this invention, the following technical solution is adopted:

[0006] Specifically, this application provides a method for analyzing and processing construction investment consulting data, which includes:

[0007] S1 uses construction drawing data as a basis to determine the distribution data of different types of buildings in the database. Based on the construction drawing data of the buildings of the aforementioned type, when it is determined that the type of building does not belong to the update requirement type, the estimation deviation type of different types of construction projects of the buildings of the aforementioned type is determined based on the estimated change data of the construction quantity of the construction drawings of the buildings of the aforementioned type.

[0008] S2, based on existing construction drawing data and estimation deviation type data of investment consulting projects, determines that when it is determined that real-time update processing of investment consulting projects is not required in the database of the building type, it determines the update strategy for the change items of construction quantities of investment consulting projects based on the similarity of construction projects of the estimation deviation type in the database of investment consulting projects with estimation changes. Based on the update strategy for the change items of construction quantities of investment consulting projects, it determines whether the identification processing of construction drawing data of investment consulting projects is required when updating the database of investment consulting projects of the building type.

[0009] The beneficial effects of this invention are as follows:

[0010] Based on the similarity of construction projects with estimation deviation types in the database that have estimation changes, a strategy for updating the change items of construction quantities in investment consulting projects is determined. This ensures the assessment of the dispersion of the risk distribution of estimation deviation types of construction projects associated with investment consulting projects due to differences in the similarity of construction projects with estimation changes in different investment consulting projects. This guarantees the efficiency and reliability of the update processing when there are a large number of investment consulting projects with relatively dispersed estimation deviation distributions and changes in construction quantities.

[0011] Based on the update strategy for changes in construction quantities of investment consulting projects, this study determines whether the database of investment consulting projects of a certain type needs to perform construction drawing data identification processing when updating. This not only considers the differences in the timeliness of update processing when the construction quantities of investment consulting projects in the database change due to differences in update strategies, but also takes into account the association between the project groups associated with the investment consulting projects during the update processing and the construction projects of the estimation deviation type. This ensures comprehensive updates for investment consulting projects with high timeliness requirements, while avoiding the waste of database storage space caused by updating when similar construction projects exist in the database due to the lack of construction drawing identification processing in cases where the timeliness requirements for update processing are not high.

[0012] Furthermore, the types of buildings include residential buildings, office buildings, sports venues, and shopping mall buildings.

[0013] It should be noted that, in one possible embodiment, the construction project, such as the facade project, includes dry-hanging stone, real stone paint / imitation stone paint coating, and glass curtain wall.

[0014] Furthermore, determining that the type of building does not fall under the category of renovation needs specifically includes:

[0015] Based on the construction drawing data of the building of the aforementioned type, determine the investment consulting project data of the building of the aforementioned type in the database;

[0016] Based on the investment consulting project data in the database, determine the similarity of the construction projects for the construction drawings of the aforementioned type of investment consulting projects;

[0017] Using the aforementioned similar circumstances, it can be determined whether the type of building falls under the category of renovation demand.

[0018] Furthermore, determining whether the identification and processing of the construction drawing data for the investment consulting project is necessary specifically includes:

[0019] Based on the investment consulting projects that need to be updated in the database, determine the overlap between the investment consulting projects and the construction projects in the existing project groups, and determine the associated project groups of the investment consulting projects based on the overlap.

[0020] Based on the estimated deviation items in the associated project group, identify the investment consulting projects with estimated deviation items that adopt a preset update strategy.

[0021] Based on the investment consulting projects with the aforementioned estimation deviation that employ a preset update strategy, the investment consulting project data in the associated project group, and the investment consulting project data with the preset update strategy, it is determined whether the construction drawing data of the investment consulting projects that need updating needs to be identified and processed.

[0022] Secondly, the present invention provides a computer system comprising: a memory and a processor connected in communication, and a computer program stored in the memory and capable of running on the processor, wherein the processor executes the above-described method for analyzing and processing construction investment consulting data when running the computer program.

[0023] Other features and advantages will be set forth in the following description, and the objects and other advantages of the invention are realized and obtained through the structures particularly pointed out in the description and the drawings.

[0030] To enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. Based on the embodiments of this specification, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this specification.

[0031] In this application, by utilizing the estimation deviations of the quantities of different construction projects, the estimation deviations of the quantities of construction projects involved in the consulting investment projects in the database are cleaned up, and the investment consulting projects are updated in the database in a timely manner, thereby ensuring the reliability of the quantity estimation in subsequent investment consulting projects.

[0032] Example 1

[0033] like Figure 1 As shown, this application provides a method for analyzing and processing construction investment consulting data, specifically including:

[0034] S1 uses construction drawing data as a basis to determine the distribution data of different types of buildings in the database. Based on the construction drawing data of the buildings of the aforementioned type, when it is determined that the type of building does not belong to the update requirement type, the estimation deviation type of different types of construction projects of the buildings of the aforementioned type is determined based on the estimated change data of the construction quantity of the construction drawings of the buildings of the aforementioned type.

[0035] Furthermore, the types of buildings include residential buildings, office buildings, sports venues, and shopping mall buildings.

[0036] It should be noted that, in one possible embodiment, the construction project, such as the facade project, includes dry-hanging stone, real stone paint / imitation stone paint coating, and glass curtain wall.

[0037] Specifically, such as Figure 2 As shown, determining that the type of building does not belong to the type of renovation requirement specifically includes:

[0038] Based on the construction drawing data of the building of the aforementioned type, determine the investment consulting project data of the building of the aforementioned type in the database;

[0039] Based on the investment consulting project data in the database, determine the similarity of the construction projects for the construction drawings of the aforementioned type of investment consulting projects;

[0040] Using the aforementioned similar circumstances, it can be determined whether the type of building falls under the category of renovation demand.

[0041] It is understandable that, by utilizing the aforementioned similar circumstances, determining whether the building type falls under the category of renovation needs specifically includes:

[0042] Based on the aforementioned similarities, investment consulting projects with identical construction projects are grouped into the same project group;

[0043] Based on the project group data, determine whether the building type belongs to the type of renovation requirement.

[0044] Specifically, when the number of project groups for the type of building in the database does not meet the requirements, that is, when the number of project groups is small, the number of investment consulting projects that can be referenced in the database during the subsequent estimation of the engineering quantity of the investment consulting project is small. Therefore, it is determined that the type of building belongs to the update requirement type.

[0045] In one possible embodiment, if the number of project groups for the building type in the database is less than a threshold, which is less than 15 in one possible embodiment, then the building type is determined to belong to the update requirement type.

[0046] It should be noted that when the building type belongs to the update requirement type, when updating the investment consulting project in the database of the building type, there is no need to identify the construction drawing data of the investment consulting project; the update process can be performed directly.

[0047] Specifically, the method for determining the type of estimation deviation for the construction project is as follows:

[0048] Based on the estimated change data of the construction volume in the construction drawings of the building of the aforementioned type, determine the deviation between the construction volume of the construction project during the construction process and the estimated construction volume in the investment consulting report;

[0049] Based on the aforementioned deviations, investment consulting projects in which the construction volume of the construction project has changed are identified.

[0050] Using investment consulting projects where the construction volume of the aforementioned construction project has changed, determine the type of estimation deviation for the aforementioned construction project.

[0051] It should be noted that when the number of investment consulting projects whose construction volume has changed is within a preset range, the estimation deviation type of the construction project is determined to be a serious deviation type; when the number of investment consulting projects whose construction volume has changed is not within a preset range, the estimation deviation type of the construction project is determined to be a general deviation type.

[0052] In one possible embodiment, if the number of investment consulting projects in which the construction quantity of the construction project changes is greater than 20, then the estimation deviation type of the construction project is determined to be a severe deviation type.

[0053] S2, based on existing construction drawing data and estimation deviation type data of investment consulting projects, determines that when it is determined that real-time update processing of investment consulting projects is not required in the database of the building type, it determines the update strategy for the change items of construction quantities of investment consulting projects based on the similarity of construction projects of the estimation deviation type in the database of investment consulting projects with estimation changes. Based on the update strategy for the change items of construction quantities of investment consulting projects, it determines whether the identification processing of construction drawing data of investment consulting projects is required when updating the database of investment consulting projects of the building type.

[0054] It should be noted that the existing investment consulting projects mentioned are those that require the generation of investment consulting reports before construction.

[0055] Specifically, determining that real-time updates of investment consulting projects are not required in the database of the building types includes:

[0056] Based on the construction drawing data of the existing investment consulting projects, identify the existing investment consulting projects with serious deviations.

[0057] Existing investment consulting projects with serious deviations are identified as projects of interest. The similarity between these projects and construction projects in the investment consulting database is used to determine whether there are any projects of interest in the database that are completely identical to construction projects.

[0058] By utilizing the data of investment consulting projects in the database that do not contain identical construction projects, it can be determined whether real-time updates of investment consulting projects are required in the database for the building type.

[0059] It should be noted that when the number of investment consulting projects in the database that do not have the exact same construction projects does not meet the requirements, the reliability of estimating the construction volume using investment consulting projects in the database is poor. Therefore, it is determined that real-time updates of investment consulting projects are needed in the database of the building type.

[0060] It is understandable that when real-time updates of investment consulting projects are required in the database of building types, the updating of investment consulting projects in the database of building types does not require the identification and processing of the construction drawing data of the investment consulting projects, and the updating process can be carried out directly.

[0061] In one possible embodiment, if there are at least two investment consulting projects in the database that are completely identical to the construction projects, then it is determined that real-time updates of the investment consulting projects need to be performed in the database of the building type.

[0062] Optionally, the method for determining the update strategy for changes in the construction quantity of the investment consulting project is as follows:

[0063] Based on the correlation between investment consulting projects and construction projects with estimation deviation types in the database, construction projects with serious deviation types in investment consulting projects in each project group are identified and identified as associated deviation projects.

[0064] Based on the associated deviation item data in each item group, the associated deviation items that have experienced estimation deviations in each item group are identified and designated as estimated deviation items. The sum of the number of estimated deviation items and the number of associated deviation items is taken as the total number of deviation items.

[0065] Based on the total number of deviation items in the investment consulting project and the deviation of construction projects among project groups with estimated deviation items, an update strategy for the change items of the construction quantity in the investment consulting project is determined.

[0066] It is understandable that when the total number of deviation items in the project group to which the investment consulting project belongs does not meet the requirements, and the number of related deviation items or the estimated number of deviation items in the project group to which the investment consulting project belongs is large, then in order to ensure the reliability of the update processing of related deviation items, the update strategy for the change items of the construction quantity of the investment consulting project is determined to be a preset update strategy.

[0067] Additionally, it should be noted that when the total number of deviation projects in the project group to which the investment consulting project belongs meets the requirements, the distributed discrete projects among the estimated deviation projects are determined by the maximum number of deviations in the construction projects among the project groups to which the estimated deviation projects exist. Specifically, when the maximum number of deviations in the construction projects among the project groups to which the estimated deviation projects exist is greater than a preset number and the number of project groups to which the estimated deviation projects exist is not less than a preset number of projects, the estimated deviation project is determined to be a distributed discrete project. In this case, it is considered an estimated deviation project in all combinations of construction projects, so its distribution can be directly determined to be relatively discrete. When the number of distributed discrete projects in the project group to which the investment consulting project belongs does not meet the requirements, the update strategy for the change items of the construction quantity of the investment consulting project is determined to be the preset update strategy; otherwise, other update strategies are used.

[0068] Optionally, determining whether the construction drawing data identification processing for the investment consulting project is required includes:

[0069] Based on the investment consulting projects that need to be updated in the database, determine the overlap between the investment consulting projects and the construction projects in the existing project groups, and determine the associated project groups of the investment consulting projects based on the overlap.

[0070] Based on the estimated deviation items in the associated project group, determine the number of investment consulting projects and the number of estimated deviation items in the associated project group;

[0071] Based on the number of investment consulting projects using a preset update strategy among the investment consulting projects with the aforementioned estimation deviation, and the number of investment consulting projects in the associated project group, it is determined whether the identification and processing of the construction drawing data of the investment consulting projects that need to be updated is required.

[0072] If it is determined that the investment consulting project that needs to be updated does not have an associated project group or the number of investment consulting projects in the associated project group does not meet the requirement (i.e., less than 5), then it is determined that the construction drawing data of the investment consulting project that needs to be updated does not need to be identified and processed, and can be updated directly.

[0073] Furthermore, if the number of investment consulting projects in the associated project group meets the requirements, and the number of estimated deviation projects in the associated project group is greater than the preset estimated deviation project number threshold, i.e., not less than 4, then it is determined that the construction drawing data of the investment consulting project that needs to be updated does not need to be identified and processed, and can be directly updated.

[0074] Additionally, it can be understood that when the number of estimated deviation projects in the associated project group is not greater than a preset threshold for the number of estimated deviation projects, based on the investment consulting projects in the associated project group that adopt the preset update strategy and have estimated deviation projects, the number of investment consulting projects in the associated project group that adopt the preset update strategy and have estimated deviation projects is determined. When the number of investment consulting projects that adopt the preset update strategy determines that there are update deviation projects in the estimated deviation projects, that is, when the number of investment consulting projects in the associated project group that adopt the preset update strategy and have estimated deviation projects is less than 6, it is determined to be an update deviation project. Therefore, the construction drawing data of the investment consulting project that needs to be updated does not need to be identified and processed, and can be directly updated.

[0075] Furthermore, if it is determined, based on the number of investment consulting projects using the preset update strategy, that there are no update deviation projects among the estimated deviation projects, then it is determined that the construction drawing data of the investment consulting projects that need to be updated will be identified and processed.

[0076] Example 2

[0077] Secondly, such as Figure 4 As shown, the present invention provides a computer system, including: a memory and a processor connected in communication, and a computer program stored in the memory and capable of running on the processor, wherein the processor executes the above-described method for analyzing and processing construction investment consulting data when running the computer program.

[0078] Specifically, such as Figure 3 As shown, the method for determining the update strategy for changes in the construction quantity of the investment consulting project is as follows:

[0079] Based on the correlation between investment consulting projects and construction projects with estimation deviation types in the database, construction projects with serious deviation types in investment consulting projects in each project group are identified and identified as associated deviation projects.

[0080] Based on the data of associated deviation items in each item group, identify the associated deviation items that have caused estimation deviations in each item group and use them as estimation deviation items.

[0081] Based on the estimated deviation data of the deviation items in each project group and the deviation of construction items between each project group, the update strategy for the change items of the construction quantity of the investment consulting project is determined.

[0082] It is understandable that when the number of related deviation items or the number of estimated deviation items in the project group to which the investment consulting project belongs does not meet the requirements, and the number of related deviation items or the number of estimated deviation items in the project group to which the investment consulting project belongs is large, then, in order to ensure the reliability of the update processing of related deviation items, the update strategy for the change items of the construction quantity of the investment consulting project is determined to be a preset update strategy.

[0083] In one possible embodiment, when the number of related deviation projects or the number of estimated deviation projects in the project group to which the investment consulting project belongs is greater than 3, the update strategy for the change item of the construction quantity of the investment consulting project is determined to be the preset update strategy.

[0084] It should also be noted that when the number of related deviation items and the number of estimated deviation items in the project group to which the investment consulting project belongs both meet the requirements, if there are no related deviation items or no estimated deviation items in the project group to which the investment consulting project belongs, then the update strategy for the change item of the construction quantity of the investment consulting project is determined to be other update strategies.

[0085] Furthermore, when there are related deviation projects and estimated deviation projects in the project group to which the investment consulting project belongs, it is necessary to further determine whether the number of investment consulting projects in the project group matches the number of related deviation projects and the number of estimated deviation projects. If either the ratio of the number of investment consulting projects to the number of related deviation projects or the ratio of the number of investment consulting projects to the number of estimated deviation projects is less than a preset ratio threshold, i.e., less than 2, then the update strategy for the change item of the construction quantity of the investment consulting project is determined to be the preset update strategy.

[0086] Furthermore, if the ratio of the number of investment consulting projects to the number of associated deviation projects and the ratio of the number of investment consulting projects to the number of estimated deviation projects are both not less than a preset ratio threshold, then the deviation of construction projects among project groups with estimated deviation projects is determined based on the deviation situation. The maximum number of deviations of construction projects among project groups with estimated deviation projects is used to determine the distributed discrete projects among the estimated deviation projects. Specifically, when the maximum number of deviations of construction projects among project groups with estimated deviation projects is greater than 4 and the number of project groups with estimated deviation projects is not less than 3, then the estimated deviation project is determined to be a distributed discrete project. In this case, it is considered an estimated deviation project in various construction project combinations, so its distribution can be directly determined to be relatively discrete. When the number of distributed discrete projects in the project group to which the investment consulting project belongs does not meet the requirement, i.e., not less than 2, then the update strategy for the change item of the construction quantity of the investment consulting project is determined to be the preset update strategy.

[0087] It is understandable that when the number of discrete projects in the project group to which the investment consulting project belongs meets the requirements, the update strategy for the change item of the construction quantity of the investment consulting project is determined to be other update strategies.

[0088] Specifically, the preset update strategy is to immediately update the database with the change in the construction quantity of the investment consulting project when there is a change in the construction quantity of the construction project. The other update strategy is that when there is a change in the construction quantity of the construction project, if the change occurs in a construction project with a serious deviation type, the change in the construction quantity of the investment consulting project is immediately updated in the database. However, if there is no change in the construction quantity of a construction project with a serious deviation type, the change in the construction quantity of the investment consulting project is only required in the database when there are multiple construction projects with changes in the construction quantity.

[0089] Optionally, determining that the type of building does not belong to the type of renovation requirement includes:

[0090] Based on the construction drawing data of the building of the aforementioned type, determine the investment consulting project data of the building of the aforementioned type in the database;

[0091] The number of investment consulting projects of the aforementioned type is determined based on the investment consulting project data in the database;

[0092] By using the number of investment consulting projects of the aforementioned type, it can be determined whether the building type falls under the category of renovation demand.

[0093] It is understood that when the number of investment consulting projects of the aforementioned type is less than a preset threshold for the number of consulting projects, the building type is determined to belong to the type of renovation demand.

[0094] Example 3

[0095] Optionally, it can be determined that real-time updates of investment consulting projects are not required in the database of building types, specifically including:

[0096] Based on the construction drawing data of the existing investment consulting projects, identify the existing investment consulting projects with serious deviations.

[0097] Based on existing investment consulting projects for construction projects with severe deviations, identify existing investment consulting projects associated with the construction projects with severe deviations and treat them as associated investment projects.

[0098] Using the associated investment project data of the construction projects of the aforementioned severe deviation type, it is determined whether real-time updates of the investment consulting projects are required in the database of the building type.

[0099] It is understood that the existing investment consulting projects associated with the construction projects of the aforementioned severe deviation type are existing investment consulting projects that contain construction projects of the aforementioned severe deviation type.

[0100] It should be noted that when the number of construction projects of the serious deviation type that do not meet the requirements of the number of related investment projects exceeds the preset project number threshold, or when the number of existing investment consulting projects with the serious deviation type does not meet the requirements, it is determined that real-time updating of investment consulting projects is required in the database of the building type.

[0101] In one possible embodiment, when there are more than 5 construction projects of the serious deviation type with more than 2 related investment projects, or when there are at least 3 existing investment consulting projects of the serious deviation type, it is determined that real-time update processing of investment consulting projects is required in the database of building types.

[0102] Example 4

[0103] Specifically, determining whether the construction drawing data identification processing for the investment consulting project is required includes:

[0104] Based on the investment consulting projects that need to be updated in the database, determine the overlap between the investment consulting projects and the construction projects in the existing project groups, and determine the associated project groups of the investment consulting projects based on the overlap.

[0105] Based on the estimated deviation items in the associated project group, identify the investment consulting projects with estimated deviation items that adopt a preset update strategy.

[0106] Based on the investment consulting projects with the aforementioned estimation deviation that employ a preset update strategy, the investment consulting project data in the associated project group, and the investment consulting project data with the preset update strategy, it is determined whether the construction drawing data of the investment consulting projects that need updating needs to be identified and processed.

[0107] It is understandable that when the proportion of investment consulting projects using the preset update strategy in the database is less than the preset proportion threshold, the update processing time for construction projects with serious deviations is difficult to meet the requirements. Therefore, based on this, it is determined that the construction drawing data of the investment consulting projects that need to be updated does not need to be identified and processed, and can be directly updated.

[0108] In one possible embodiment, when the proportion of investment consulting projects using the preset update strategy in the database is less than 0.5, it is determined that the proportion of investment consulting projects using the preset update strategy in the database is less than the preset proportion threshold.

[0109] Additionally, it should be noted that when the number of investment consulting projects using the preset update strategy in the database is not less than the preset update quantity threshold, and it is determined that the investment consulting project that needs to be updated does not have an associated project group or the number of investment consulting projects in the associated project group does not meet the requirements (i.e., less than 5), then it is determined that the construction drawing data of the investment consulting project that needs to be updated does not need to be identified and processed, and can be directly updated.

[0110] Furthermore, if the number of investment consulting projects in the associated project group meets the requirements, and the number of estimated deviation projects in the associated project group is greater than the preset estimated deviation project number threshold, i.e., not less than 4, then it is determined that the construction drawing data of the investment consulting project that needs to be updated does not need to be identified and processed, and can be directly updated.

[0111] Additionally, it can be understood that when the number of estimated deviation projects in the associated project group is not greater than a preset threshold for the number of estimated deviation projects, based on the investment consulting projects in the associated project group that adopt the preset update strategy and have estimated deviation projects, the number of investment consulting projects in the associated project group that adopt the preset update strategy and have estimated deviation projects is determined. When the number of investment consulting projects that adopt the preset update strategy determines that there are update deviation projects in the estimated deviation projects, that is, when the number of investment consulting projects in the associated project group that adopt the preset update strategy and have estimated deviation projects is less than 6, it is determined to be an update deviation project. Therefore, the construction drawing data of the investment consulting project that needs to be updated does not need to be identified and processed, and can be directly updated.

[0112] Furthermore, when it is determined by the number of investment consulting projects using the preset update strategy that there are no update deviation projects in the estimated deviation projects, the identification and processing scheme for the construction drawing data of the investment consulting projects that need to be updated is determined by the average number of investment consulting projects using the preset update strategy that have estimated deviation projects in the associated project group.

[0113] It should be noted that when the average number of investment consulting projects with estimation deviations in the associated project group that adopt the preset update strategy is greater than the preset consulting project number threshold, i.e., greater than 10, it is determined that the construction drawing data of the investment consulting project that needs to be updated will be identified and processed. However, when the average number of investment consulting projects with estimation deviations in the associated project group that adopt the preset update strategy is not greater than the preset consulting project number threshold, it is determined that the construction drawing data of the investment consulting project that needs to be updated does not need to be identified and processed directly.

[0114] It is understandable that when it is necessary to identify and process the construction drawing data of the investment consulting project that needs to be updated, the similarity between the construction drawing of the investment consulting project that needs to be updated and the construction drawing of the investment consulting project in the database is used to determine whether it is necessary to update the construction drawing of the investment consulting project that needs to be updated in the database. Specifically, when there is a construction drawing in the database of the investment consulting project that needs to be updated with a similarity greater than a preset similarity threshold, i.e., greater than 0.9, it is determined that it is not necessary to update the database of the building of that type.

[0115] It should be noted that the similarity is determined based on the Euclidean distance function.
