[0002] In the field of construction engineering, the approval management of planning schemes is a key link in project implementation. With the popularization and application of BIM technology in engineering construction, the traditional planning scheme approval management mode relying on manual operation and paper document circulation has gradually failed to adapt to the needs of digital management.

[0003] There are still several problems in the existing planning scheme approval management technology: 1. When manually reviewing planning schemes, the subjective factors have a great influence, and it is difficult to accurately analyze and evaluate the planning index parameters. For the review of hard planning index parameters, manual comparison and calculation are prone to errors, and the accuracy of the review results cannot be guaranteed.

[0004] 2. When matching historical input operation schemes, there is a lack of scientific similarity analysis method, and it is difficult to accurately find the most similar historical scheme to the target planning scheme, and it is difficult to fully utilize historical data to provide reference for the review and optimization of the current scheme.

[0005] 3. When reviewing planning schemes, only the compliance of the scheme is concerned, and the actual effect after the scheme is put into operation is ignored. The planning scheme cannot be evaluated based on historical operation data, which may lead to various problems in the actual operation of the selected scheme, affecting the social and economic benefits of the project.

[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0028] Please refer to Figure 1As shown, the first aspect of the present application provides a BIM-based planning scheme approval management method, comprising: S1, preliminary checking of reported materials: collecting each planning scheme reported by the target residential planning area, extracting the material directory reported by each planning scheme, and the target approval platform performing preliminary checking of reported materials on each planning scheme through a preset material reporting rule to screen out each preliminary examination scheme.

[0029] Please refer to Figure 3 As shown, in a specific embodiment of the present application, the specific process of screening out each preliminary examination scheme is: extracting each material name from the material directory reported by each planning scheme, and performing word segmentation processing on each material name to obtain the material keywords of each material reported by each planning scheme.

[0030] In a specific embodiment of the present application, the material keywords include but are not limited to project approval, land ownership certificate, design achievement file, environmental protection commitment, technical analysis file, fire special specification, etc.

[0031] Extract the hard keyword library corresponding to the reported material from the preset material reporting rule, and match the material keywords of each material reported by each planning scheme with the hard keyword library.

[0032] If the material keywords of each material reported by a planning scheme do not completely satisfy each keyword in the hard keyword library, it indicates that the reported materials of the planning scheme are not complete, otherwise, if the material keywords of each material reported by a planning scheme completely satisfy each keyword in the hard keyword library, it indicates that the reported materials of the planning scheme are complete, and the planning scheme is recorded as a preliminary examination scheme, thereby obtaining each preliminary examination scheme.

[0033] S2, collaborative review by the review department: based on BIM, automatically extracting planning information of each preliminary examination scheme, and extracting each hard planning index parameter of the review department, thereby performing collaborative review by the review department on each preliminary examination scheme, and screening out each target planning scheme.

[0034] It should be noted that each hard planning index parameter of the review department is extracted from the review reference file of the review department.

[0035] In a specific embodiment of the present application, each hard planning index parameter of each review department includes but is not limited to volumetric ratio, building density, green space ratio, building height, building setback distance, and number of parking spaces of the planning department. Building spacing, fire access width, and seismic fortification grade of the housing department. Number of entrances, number of traffic lights, and number of zebra crossings of the traffic department. Fire partition area, length and width of evacuation passage, and number of fire facility configurations of the fire department. Area and protection level of civil air defense engineering of the civil air defense department.

[0036] In the embodiment of the present application, the specific process of screening out each target planning scheme is: extracting each planning index parameter from the planning information of each preliminary examination scheme, and comparing each planning index parameter of each preliminary examination scheme with each hard planning index parameter of the examination department.

[0037] If a planning index parameter in a preliminary examination scheme is less than the hard planning index parameter of the examination department, it indicates that the preliminary examination scheme does not meet the planning requirements, and if any planning index parameter in a preliminary examination scheme is greater than or equal to the hard planning index parameter of the examination department, it indicates that the preliminary examination scheme meets the planning requirements, and it is recorded as a secondary examination scheme, thereby obtaining each target planning scheme.

[0038] The embodiment of the present application realizes the automation of material examination, reduces manual operation, improves examination efficiency, realizes real-time sharing and collaborative processing of information through collaborative examination of each examination department based on BIM technology, and greatly shortens the reporting period.

[0039] S3, planning index matching degree evaluation: based on the collaborative examination rules of the examination department, the index matching degree of each target planning scheme and the examination department is evaluated.

[0040] In the embodiment of the present application, the specific process of evaluating the index matching degree of each target planning scheme and the examination department is: screening each hard planning index parameter of each examination department from each hard planning index parameter of the examination department, and extracting each planning index parameter of each target planning scheme from each planning index parameter of each preliminary examination scheme.

[0041] Matching each hard planning index parameter of each examination department with each planning index parameter of each target planning scheme obtains each planning index parameter of each examination department belonging to each target planning scheme.

[0042] The difference between each planning index parameter of each examination department belonging to each target planning scheme and the hard planning index parameter of the examination department is calculated, and the difference is divided by the hard planning index parameter of the examination department, to obtain the matching degree of each planning index parameter of each examination department belonging to each target planning scheme, and the mean value is calculated to obtain the index matching degree of each examination department belonging to each target planning scheme.

[0043] The index matching degree of each examination department belonging to each target planning scheme is weighted and summed with the examination proportion weight of each examination department in the target project stored in the database to obtain the index matching degree of each target planning scheme and the examination department.

[0044] In one specific embodiment of the present application, the proportion of the review of each review department in the target project stored in the database can be determined according to policy guidance, project type characteristics, historical approval data, expert evaluation and local management priorities.

[0045] Exemplarily, taking a new residential community project in a core area of a city as an example, the planning department needs to control core indicators such as plot ratio, and the weight is set to 30%. The traffic department needs to focus on the evaluation of the number of entrances and exits, the number of traffic lights and the number of zebra crossings, and the weight is 25%. The fire department considers that the residential community is densely populated and has high fire safety requirements, and the weight is 20%. The housing and construction department is responsible for building structure safety and construction standards, and the weight is 15%. The air defense department considers the air defense engineering area and protection level of the project, and the weight is 10%. The setting of each weight matches the key needs of the project in space planning, traffic relief, safety protection, etc., ensuring that the review focus matches the risk points of the project.

[0046] In the embodiment of the present application, the planning information and the hard planning index parameters are automatically extracted by using the BIM technology, and the index matching degree is evaluated by a scientific calculation and analysis method, thereby reducing the influence of subjective factors and improving the accuracy and scientificity of the review results.

[0047] S4, input operation scheme matching: extracting each input operation scheme from historical approval cases, and extracting planning information of each input operation scheme, thereby matching the target input operation scheme corresponding to each target planning scheme.

[0048] In the specific embodiment of the present application, the specific process of matching the target input operation scheme corresponding to each target planning scheme is as follows: extracting each planning index parameter from the planning information of each input operation scheme, and performing similarity analysis based on each planning index parameter of each target planning scheme to obtain the planning index similarity between each target planning scheme and each input operation scheme.

[0049] In the specific embodiment of the present application, the specific process of obtaining the planning index similarity between each target planning scheme and each input operation scheme is as follows: performing corresponding difference on each planning index parameter of each target planning scheme and each planning index parameter of each input operation scheme, taking the absolute value of the difference, and obtaining the planning index parameter deviation between each target planning scheme and each input operation scheme.

[0050] The deviation value of the set reference is subtracted from each planning index parameter deviation, and the difference value is divided by the deviation value of the set reference to obtain the similarity of each planning index parameter between each target planning scheme and each input operation scheme, and the mean value is calculated to obtain the planning index similarity between each target planning scheme and each input operation scheme.

[0051] Extract the input operation scheme corresponding to the maximum planning index similarity from the planning index similarity between each target planning scheme and each input operation scheme, and take the input operation scheme as the target input operation scheme corresponding to each target planning scheme.

[0052] The embodiment of the present application accurately matches the historical input operation scheme by a scientific similarity analysis method, fully utilizes the historical data to provide a reference for the review and optimization of the current scheme, and improves the quality and feasibility of the scheme.

[0053] S5, actual operation applicability evaluation: extracting the operation investigation information of the target input operation scheme corresponding to each target planning scheme, and evaluating the actual operation applicability of the target input operation scheme corresponding to each target planning scheme based on the operation investigation information.

[0054] In the embodiment of the present application, the specific process of evaluating the actual operation applicability of the target input operation scheme corresponding to each target planning scheme is: extracting the historical unsatisfied complaint times of each planning index parameter correlation level and the complaint time point and rectification time point corresponding to each unsatisfied complaint from the operation investigation information of the target input operation scheme corresponding to each target planning scheme, and analyzing the actual operation satisfaction and rectification timeliness of the target input operation scheme corresponding to each target planning scheme.

[0055] It should be noted that the historical unsatisfied complaint times of each planning index parameter correlation level and the complaint time point and rectification time point corresponding to each unsatisfied complaint are all extracted from the property management system of the target input operation scheme.

[0056] In one embodiment of the present application, for the planning scheme of a residential area, the planning index parameter correlation level mainly includes but is not limited to the living environment (such as insufficient green space ratio of the community, too high building density), supporting facilities (insufficient number of parking spaces leading to parking difficulty complaints), traffic travel (unreasonable number of community entrances leading to congestion), safety guarantee (too narrow length and width of evacuation passage leading to safety hazard complaints), sunlight and lighting (too close building spacing leading to insufficient lighting of some residents), etc. The historical complaint times, complaint and rectification time points of these dimensions can directly reflect the satisfaction of residents to the actual operation effect of the planning scheme and the rectification efficiency.

[0057] In the embodiment of the present application, the specific way of analyzing the actual operation satisfaction of the target input operation scheme corresponding to each target planning scheme is: accumulating the historical unsatisfied complaint times of each planning index parameter correlation level of the target input operation scheme corresponding to each target planning scheme to obtain the historical unsatisfied complaint times of the target input operation scheme corresponding to each target planning scheme.

[0058] The complaint number set as a reference is subtracted from the historical unsatisfactory complaint number, and the difference is divided by the complaint number set as a reference, to obtain the actual operation satisfaction degree of the target input operation scheme corresponding to each target planning scheme.

[0059] It should be noted that the specific process of analyzing the rectification timeliness of the target input operation scheme corresponding to each target planning scheme is that the complaint time point and the rectification time point corresponding to each unsatisfactory complaint at the level of each planning index parameter correlation are compared, the rectification response time length corresponding to each unsatisfactory complaint at the level of each planning index parameter correlation is obtained, and the average rectification response time length at the level of each planning index parameter correlation is obtained by taking the average value.

[0060] The rectification response time length set as a reference is subtracted from the average rectification response time length at the level of each planning index parameter correlation, and the difference is divided by the rectification response time length set as a reference, to obtain the rectification timeliness at the level of each planning index parameter correlation, and the rectification timeliness of the target input operation scheme corresponding to each target planning scheme is obtained by taking the average value.

[0061] The actual operation satisfaction degree and the rectification timeliness of the target input operation scheme corresponding to each target planning scheme are weighted and summed according to the corresponding proportion weight, to obtain the actual operation applicability of the target input operation scheme corresponding to each target planning scheme.

[0062] In one specific embodiment of the present application, for the building planning of a residential community, the proportion weight of the actual operation satisfaction degree is usually larger, because the residential community directly serves the daily life of residents, and the quality of the living experience has a profound impact on the happiness of residents. The satisfaction degree of residents on the living environment, supporting facilities, property services, etc. is directly related to the long-term reputation and social stability of the community. Although the rectification timeliness is also very important, in the case of reasonable planning scheme design and careful consideration in the early stage, the rectification demand is relatively limited, and the ultimate goal of the rectification timeliness is still to improve the satisfaction degree of residents. Therefore, in the weight distribution, the actual operation satisfaction degree occupies the dominant position, so the proportion weights of the actual operation satisfaction degree and the rectification timeliness can be 0.65 and 0.35 respectively.

[0063] The embodiment of the present application evaluates the actual operation applicability of the target input operation scheme, fully considers the satisfaction degree and the rectification timeliness of the scheme in the actual operation, and ensures that the selected scheme is not only compliant, but also has good actual operation effect.

[0064] S6, best planning scheme confirmation: based on the index matching degree and the actual operation applicability, the best planning scheme corresponding to the target residential planning area is confirmed.

[0065] In specific embodiments of the present application, the specific way of confirming the optimal planning scheme corresponding to the target residential planning area is as follows: the index fitting degree of each target planning scheme with the auditing department and the actual operation applicability of the target input operation scheme corresponding to each target planning scheme are respectively weighted and summed with the corresponding proportion weight to obtain a comprehensive adaptation index of each target planning scheme, and the target planning scheme corresponding to the maximum comprehensive adaptation index is extracted as the optimal planning scheme corresponding to the target residential planning area.

[0066] In one specific embodiment of the present application, the actual operation applicability weight proportion is larger for the building planning of the residential community, because the residential community directly faces the life of residents, and its functional practicability and living experience are crucial. The actual operation applicability covers core dimensions such as resident satisfaction and rectification efficiency, and directly affects the living quality and social benefits. Although the index fitting degree ensures that the scheme meets the regulations and technical standards, it is more necessary to focus on the actual effect after the scheme is implemented on the basis of meeting the basic compliance. Therefore, the actual operation applicability occupies the dominant position in the weight distribution to ensure that the selected optimal scheme has both compliance and people's livelihood value, so the proportion weight of the index fitting degree and the actual operation applicability can be respectively 0.4 and 0.6.

[0067] Referring to Figure 2 The second aspect of the present application provides a BIM-based planning scheme approval management system, which comprises: a reporting material preliminary verification module, an auditing department collaborative auditing module, a planning index fitting degree evaluation module, an input operation scheme matching module, an actual operation applicability evaluation module, and an optimal planning scheme confirmation module.

[0068] It should be noted that the present application also includes a database for storing the auditing proportion weight of each auditing department in the target project.

[0070] The reporting material preliminary verification module collects each planning scheme corresponding to the reporting of the target residential planning area, extracts the material directory reported by each planning scheme, and the target approval platform performs preliminary verification on the reporting materials of each planning scheme through the preset reporting material rules to screen out each preliminary examination scheme.

[0071] The auditing department cooperative auditing module automatically extracts planning information of each preliminary examination scheme based on BIM, extracts hard planning index parameters of the auditing department, and performs auditing department cooperative auditing on each preliminary examination scheme according to the planning information and the hard planning index parameters, and screens out each target planning scheme.
