Description

Technical Field

[0001] The present invention relates to the technical field of construction scheduling management, and in particular to a method for construction scheduling based on a building engineering model. Background Art

[0002] In the field of construction engineering, construction scheduling is a key link to ensure the smooth progress of the project. With the continuous development of the construction industry, the scale and complexity of engineering projects are increasing. Traditional construction scheduling methods often rely on experience and judgment, lacking systematicity and scientificity. The emergence of technologies such as Building Information Modeling (BIM) has provided new means for construction scheduling, but how to make full use of building engineering models for efficient and accurate construction scheduling is still a problem that needs to be solved.

[0003] According to the publication number CN116307537A, a method and system for construction scheduling based on a building project model is disclosed. The method constructs an overall model of the building project, and then divides the overall model into building structure sub-models according to the structural composition and construction sequence of the building project. The building structure sub-models are then divided into independent structural parts. By calculating the material name, material number, material quantity, construction period and labor cost of each structural part, a relatively accurate various materials, material numbers, total material quantity and total labor cost of the entire construction project can be obtained. When performing construction scheduling, the cycle required for scheduling is set through the estimated construction period or prefabrication period of the complete structural parts under each process, so that the construction plan of the current period and the construction plan of the next period are called out according to the cycle, and optimized and adjusted in combination with the construction completion report corresponding to the construction progress, so as to determine the purchase of various materials, material numbers, and material quantities and allocate them according to the construction period.

[0004] However, the above patents and prior art have the following shortcomings when they are actually used:

[0005] First, how to accurately identify the normal and abnormal conditions of the construction area, including whether the construction progress meets the standards and whether the use of resources is reasonable;

[0006] The second point is how to conduct effective scheduling analysis to generate reasonable adjustment information for abnormal resource consumption in normal areas;

[0007] Third, for abnormal areas, how to combine construction progress data and resource usage data for comprehensive identification, and conduct targeted scheduling analysis to generate effective adjustment information;

[0008] Fourth, how to select appropriate segmented processing methods for abnormal areas according to different project characteristics and scales to improve the accuracy and effectiveness of construction scheduling. Summary of the invention

[0009] In view of the shortcomings of the prior art, the present invention provides a method for construction scheduling based on a building engineering model, which solves the problem that targeted scheduling analysis cannot be performed well according to the construction progress data and resource usage data of different areas, thereby affecting the overall construction scheduling.

[0010] To achieve the above objectives, the present invention is implemented through the following technical solutions: a method for construction scheduling based on a building engineering model, the method specifically comprising the following steps:

[0011] Step S001, obtaining corresponding construction information based on the building construction model, wherein the construction information includes construction progress data and resource usage data;

[0012] Step S002, identifying the regional construction progress according to the acquired construction information, and generating an identification result, wherein the identification result includes a normal area and an abnormal area;

[0013] Step S003, analyzing the resource usage data corresponding to the normal area, determining whether the usage is normal by calculating the resource consumption, and performing scheduling analysis on abnormal usage to generate scheduling information;

[0014] Step S004, analyzing and identifying the construction progress data of the abnormal area, and combining the resource usage data for comprehensive identification to generate an identification result, and performing scheduling analysis on the identification result to generate scheduling information.

[0015] As a further solution of the present invention: the specific method of generating the recognition result in step S002 is:

[0016] Obtain all and label them as i, where i=1, 2, ..., j, where j represents the number of construction areas, compare the construction progress data in the construction information with the standard progress data, mark the construction areas with abnormal construction progress data as abnormal areas, and mark the construction areas without abnormal construction progress data as normal areas;

[0017] Similarly, judge and mark other construction areas.

[0018] As a further solution of the present invention: the specific method of analyzing the resource usage data corresponding to the normal area in step S003 is:

[0019] All normal areas are obtained and labeled as n, where n=1, 2, ..., m, where m represents the number of normal areas. Any normal area is then obtained as the target object. Different resources in the target object are obtained and labeled as a, where a=1, 2, ..., b. The resource consumption of different resources a is then calculated and recorded as Ya, and the resource consumption Ya is compared with the normal consumption Yz.

[0020] If the resource consumption Ya is greater than the normal consumption Yz, it means that there is abnormal consumption of the corresponding resources of the target object. At the same time, the corresponding resources are acquired and marked as resources to be adjusted, and the resources to be adjusted are analyzed. Otherwise, no processing is performed.

[0021] As a further solution of the present invention: the specific method of analyzing the resources to be adjusted in step S003 is:

[0022] Obtain the resources to be adjusted and label them as o, where o=1, 2, ..., p, where p represents the number of resources to be adjusted. At the same time, obtain the minimum consumption corresponding to the resource to be adjusted o and record it as Ymin. Perform progress calculation and analysis based on the minimum consumption Ymin. If the minimum consumption Ymin can meet the construction progress requirements, generate adjustment information based on the minimum consumption. Otherwise, if the minimum consumption Ymin cannot meet the construction progress requirements, perform secondary scheduling analysis.

[0023] As a further solution of the present invention: the specific method of performing secondary scheduling analysis on the resources to be adjusted in step S003 is:

[0024] The historical data corresponding to the resource to be adjusted o is obtained, and the same type of resources to be adjusted corresponding to the normal working conditions in the historical data are obtained. Then, the progress of the obtained resources to be adjusted of the same type is calculated, and the resources to be adjusted of the same type that meet the construction progress requirements are selected as the standard to generate adjustment information.

[0025] As a further solution of the present invention: the specific method of analyzing and identifying the construction progress data of the abnormal area in step S004 is:

[0026] Get all abnormal areas, and take any abnormal area as the analysis object, then get the construction progress corresponding to the analysis object, and judge the relationship between the construction progress and the standard progress. If the construction progress is greater than the standard progress, do not process the abnormal area. If the construction progress is less than the standard progress, mark the corresponding abnormal area as an abnormal area to be adjusted.

[0027] Obtain resource usage data corresponding to the abnormal area to be adjusted, and compare the resource usage data with the corresponding resource usage data under normal circumstances. If the resource usage data of the abnormal area to be adjusted is greater than the corresponding resource usage data under normal circumstances, a greater than analysis signal is generated, otherwise a less than analysis signal is generated;

[0028] And the smaller-than-analysis signal and the larger-than-analysis signal are analyzed and processed respectively.

[0029] As a further solution of the present invention: the specific method of analyzing and processing the less than analysis signal in step S004 is:

[0030] Obtain corresponding resource usage data, and generate corresponding adjustment information based on normal resource usage data.

[0031] As a further solution of the present invention: the specific method of analyzing and processing the greater than analysis signal in step S004 is:

[0032] Obtain the corresponding abnormal area to be adjusted, and segment the construction progress corresponding to the abnormal area to be adjusted to obtain multiple groups of construction sections. Label the construction sections at the same time, then calculate the construction progress corresponding to the construction sections, and compare the construction progress with the preset value. At the same time, select the construction sections whose construction progress is less than the preset value, and mark them as abnormal construction sections, and then analyze the abnormal construction sections.

[0033] As a further solution of the present invention: the specific method of analyzing the abnormal construction section in step S004 is:

[0034] Obtain the abnormal construction section, and calculate the difference between the construction progress corresponding to the abnormal construction section and the construction progress of the normal construction section, and sum the calculated differences to get the total construction difference, then obtain the remaining construction progress and the remaining construction time, calculate the remaining construction speed based on the total construction difference, the remaining construction progress and the remaining construction time, and generate adjustment information based on the remaining construction speed.

[0035] The present invention provides a method for construction scheduling based on a building engineering model. Compared with the prior art, it has the following beneficial effects:

[0036] The present invention comprehensively acquires construction information, including construction progress data and resource usage data, through a building engineering model, and can systematically identify normal and abnormal states of a construction area, thus avoiding omissions and errors that may occur when relying solely on empirical judgment. For normal areas, by comparing the calculated resource consumption with the normal consumption, abnormal resource consumption is discovered and marked in a timely manner. At the same time, scheduling information is generated based on the calculation of data. For abnormal areas, according to the relationship between the construction progress and the standard progress, the abnormal areas are further classified into abnormal areas to be adjusted, and are processed according to different situations, thereby improving the pertinence and effectiveness of the processing of abnormal areas. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Figure 2 It is a system block diagram of the building engineering model of the present invention. DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] For example, see Figure 1 The present application provides a method for construction scheduling based on a building engineering model, the method specifically comprising the following steps:

[0041] In step S001, corresponding construction information is obtained based on the building construction model, wherein the construction information includes construction progress data and resource usage data.

[0042] In step S002, the regional construction progress is identified according to the acquired construction information, and an identification result is generated, wherein the identification result includes a normal area and an abnormal area.

[0043] Specifically, the construction area is obtained according to the building construction model and labeled as i, and i=1, 2, ..., j, where j represents the number of construction areas. Assuming there is a large-scale construction project, five construction areas are determined through the building construction model, which are labeled 1, 2, 3, 4 and 5 respectively. Then, the construction progress is judged according to the construction information corresponding to the construction area i. The construction progress data in the construction information is analyzed and identified, and the construction progress data mainly includes the construction speed and construction completion degree of the corresponding area. The construction progress data is compared with the standard progress data, and the construction areas with abnormal construction progress data are marked as abnormal areas, and the construction areas without abnormal construction progress data are marked as normal areas.

[0044] In a specific implementation, for construction area 1, its construction information shows that 80% of the foundation engineering should have been completed at this stage, but in fact only 60% has been completed. After comparing the construction progress data of this area with the standard progress data, it is found that there is a large deviation, so construction area 1 is marked as an abnormal area. The construction progress information of construction area 2 shows that its various progress data are consistent with the standard progress data, so construction area 2 is marked as a normal area.

[0045] Similarly, judge and mark other construction areas.

[0046] Next, in step S003, the resource usage data corresponding to the normal area is analyzed, and whether the usage is normal is determined by calculating the resource consumption, and scheduling analysis is performed on the abnormal usage to generate scheduling information.

[0047] The normal area identified in step S002 is obtained and labeled as n, where n=1, 2, ..., m, where m represents the number of normal areas. Then, any normal area is obtained as the target object, and different resources in the target object are obtained and labeled as a, where a=1, 2, ..., b. Then, the resource consumption of different resources a is calculated and recorded as Ya, and the resource consumption calculated here is the resource consumption in the same period, and the resource consumption Ya is compared with the normal consumption Yz, and the normal consumption here represents the corresponding resource consumption under normal working conditions. The specific value is set by the operator according to the actual situation. If the resource consumption Ya is greater than the normal consumption Yz, it means that the corresponding resources of the target object have abnormal consumption, and the corresponding resources are obtained and marked as resources to be adjusted. If the resource consumption Ya is less than the normal consumption Yz, it means that the corresponding resources of the target object do not have abnormal consumption, and no processing is performed.

[0048] Obtain the resource to be adjusted and label it as o, and o=1, 2, ..., p, where p represents the number of resources to be adjusted. At the same time, obtain the minimum consumption corresponding to the resource to be adjusted o and record it as Ymin, and use the minimum consumption Ymin as the standard for progress calculation and analysis, and the specific calculation method is: obtain the remaining tasks, and use the minimum consumption to determine whether the construction requirements are met. The specific construction requirement is whether the corresponding remaining tasks can be completed with the minimum consumption. For example, at this time, check the remaining task volume and the remaining construction period. If it is found through calculation that the remaining tasks can be completed within the specified time with a consumption of 50 units per day, then generate adjustment information with the minimum consumption as the standard. If the minimum consumption Ymin can meet the construction progress requirements, then generate adjustment information with the minimum consumption as the standard. On the contrary, if the minimum consumption Ymin cannot meet the construction progress requirements, perform secondary scheduling analysis;

[0049] The specific method of performing secondary scheduling analysis is: obtain the historical data corresponding to the resource to be adjusted o, and obtain the corresponding resources of the same type to be adjusted under normal working conditions in the historical data, then calculate the progress of the obtained resources of the same type to be adjusted, and select the resources of the same type to be adjusted that meet the construction progress requirements as the standard to generate adjustment information. Specifically, here, the first resource of the same type to be adjusted that meets the construction progress requirements is selected. For example, in the historical data, the number of resources of the same type to be adjusted obtained is 10, and then the construction progress calculation is performed in sequence, and the first resource of the same type to be adjusted that meets the construction progress requirements is selected as the standard.

[0050] Secondly, in step S004, the construction progress data of the abnormal area is analyzed and identified, and the resource usage data is combined for comprehensive identification to generate an identification result, and the identification result is subjected to scheduling analysis to generate scheduling information.

[0051] Acquire all abnormal areas, and at the same time acquire any abnormal area as the analysis object, then acquire the construction progress corresponding to the analysis object, and determine the relationship between the construction progress and the standard progress. If the construction progress is greater than the standard progress, the abnormal area will not be processed. If the construction progress is less than the standard progress, the corresponding abnormal area will be marked as an abnormal area to be adjusted. Specifically, if the construction progress is greater than the standard progress, it means that the construction progress of the corresponding abnormal area is ahead of schedule. In this case, no processing is required. Then acquire the resource usage data corresponding to the abnormal area to be adjusted, and compare the resource usage data with the corresponding resource usage data under normal circumstances. If the resource usage data of the abnormal area to be adjusted is greater than the corresponding resource usage data under normal circumstances, and the greater than here includes equal to, then a greater than analysis signal is generated. Conversely, if the resource usage data of the abnormal area to be adjusted is less than the corresponding resource usage data under normal circumstances, then a less than analysis signal is generated.

[0052] The generated less than analysis signal is processed to obtain corresponding resource usage data, and corresponding adjustment information is generated based on normal resource usage data. Specifically, the normal usage data here refers to the resource usage data corresponding to normal conditions.

[0053] The generated greater than analysis signal is processed to obtain the corresponding abnormal area to be adjusted, and the construction progress corresponding to the abnormal area to be adjusted is processed in sections. The specific section processing method is to process the construction time as the node. According to the total construction period of the project and the work content of each stage, the time node of each subtask is determined to obtain multiple groups of construction sections. At the same time, the construction sections are numbered, and then the construction progress corresponding to the construction sections is calculated. The construction progress is compared with the preset value, and the preset value here is set by the operator. The specific value is taken according to the actual situation. At the same time, the construction section whose construction progress is less than the preset value is selected and marked as an abnormal construction section;

[0054] The abnormal construction section is obtained, and the difference between the construction progress corresponding to the abnormal construction section and the construction progress of the normal construction section is calculated. The specific construction progress of the normal construction section is the average of all normal construction sections. The calculated differences are summed up to get the total construction difference. Then the remaining construction progress and the remaining construction time are obtained. The remaining construction speed is calculated based on the total construction difference, the remaining construction progress and the remaining construction time, and the adjustment information is generated based on the remaining construction speed.

[0055] Embodiment 2, as Embodiment 2 of the present invention, is implemented on the basis of Embodiment 1, and differs from Embodiment 1 in that:

[0056] In step S004, the segmented processing method for the abnormal area to be adjusted is: according to the characteristics and scale of the project, the entire construction process is divided into different stages, and the specific different stages include: preliminary preparation stage, foundation construction stage, main structure construction stage, decoration and renovation stage and completion acceptance stage.

[0057] Embodiment 3, as the embodiment 3 of the present invention, focuses on combining the implementation processes of embodiment 1 and embodiment 2 for implementation.

[0058] Some of the data in the above formulas are dimensionless and numerically calculated. Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.
