Description

Technical Field

[0001] The present invention belongs to the technical field of project process control, and specifically discloses a comprehensive evaluation and analysis system for the process of landscaping projects based on data fusion. Background Art

[0002] With the continuous advancement of urbanization, landscaping has become an indispensable element in modern urban construction. Through the implementation of landscaping, not only can the ecological environment be improved, but also the urban image and the quality of life of residents can be enhanced. Therefore, the development of landscaping projects is becoming more and more common. In this case, in order to ensure the normal development of each landscaping project without mutual influence, the process management of landscaping projects is particularly important.

[0003] The process management of landscaping projects mainly includes process planning and process follow-up evaluation. Precise and timely process management plays an important role in ensuring the smooth progress of projects. The process management of traditional landscaping projects mainly relies on manual labor, with low intelligence and the inability to display the progress of urban landscaping in a timely manner, resulting in low management efficiency of urban landscaping. To solve this problem, the Chinese invention patent with the application number 202210252530.X in the prior art discloses a landscaping management system and management method. By constructing a target urban greening map and using a data acquisition module to obtain a urban geographic vector map and a real-time urban greening map during the project construction process to construct a urban greening model, when the real-time urban greening map does not match the target urban greening map, a greening anomaly label is generated and displayed in the urban greening model in real time, so as to dispatch staff for anomaly handling according to the greening anomaly label, which can not only reduce labor costs but also improve the efficiency of garden management.

[0004] Although the above invention reduces the manual participation in the process management of landscaping projects and realizes intelligent process management, its management of the process simply focuses on the specific progress shown in the real-time urban greening map, ignoring that the construction of landscaping projects is affected by external environments such as material supply and meteorological conditions, which is likely to cause unreasonable evaluation of the project progress, resulting in the deviation of the progress evaluation from the actual situation. In addition, when identifying abnormal project progress, due to the lack of associated data, it is difficult to provide a reference for the traceability processing of process anomalies, and it may not be possible to formulate a targeted adjustment plan, affecting the optimization of the project progress and possibly causing further delays in the progress.

[0005] In addition, the above solution lacks a detailed division of management time in progress management, which is likely to cause randomness in progress management in terms of time, and there is a hidden danger of being difficult to detect progress anomalies in a timely manner, invisibly increasing the incidence of cumulative progress anomalies. Summary of the Invention

[0006] In view of the above-mentioned disadvantages of the prior art, the purpose of the present invention is to provide a comprehensive evaluation and analysis system for the progress of landscaping projects based on data fusion, which effectively makes up for the problems mentioned in the background art by optimizing the management method and management time in the progress management of landscaping projects.

[0007] The purpose of the present invention can be achieved by the following technical solutions: A comprehensive evaluation and analysis system for the progress of landscaping projects based on data fusion, including: a greening project planning information acquisition module, which is used to acquire the planned construction stages of the landscaping project, the planned time periods and planned construction quantities of each construction stage.

[0008] A material supply plan construction module, which is used to count the material categories required for each construction stage, and then construct a planned material supply schedule for each construction stage according to the material supply contract.

[0009] A meteorological prediction construction module, which is used to construct a predicted meteorological schedule for each construction stage based on the planned time periods of each construction stage using a meteorological platform.

[0010] A planned process construction module, which is used to determine the suitable meteorological information for each construction stage, and thus fuse the planned material supply schedule and the predicted meteorological schedule of each construction stage to construct a planned process schedule for each construction stage.

[0011] A planned construction personnel determination module, which is used to determine the planned construction personnel for each construction stage based on the planned process schedule of each construction stage.

[0012] A construction monitoring module, which is used to create a construction log during the construction of the landscaping project. The construction party uploads construction data and material supply data in real time at each construction stage. The construction data includes the actual construction date, actual construction quantity and actual construction personnel, and the material supply data is the actual delivery time of various materials. At the same time, meteorological information is monitored in real time during each construction stage, and then the actual process schedule, material supply schedule and meteorological schedule of each construction stage are constructed based on the uploaded construction data, material supply data and meteorological information.

[0013] A construction process compliance evaluation module, which is used to determine the evaluation period based on the planned time period of each construction stage, and thus intercept the planned process sub-schedule and actual process sub-schedule belonging to each evaluation period from the planned process schedule and actual process schedule of the corresponding construction stage for construction process compliance evaluation.

[0014] A construction process anomaly handling module, which is used to identify and trace the anomaly direction in combination with the associated schedule of material supply and meteorology when evaluating construction process anomalies, and determine the anomaly adjustment direction.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) By integrating material supply and meteorological information for the progress planning of the landscaping project and continuing to combine this information for progress evaluation during progress follow-up, the present invention realizes reasonable progress management and evaluation based on the influencing factors of project construction. This kind of progress management not only improves the accuracy and reliability of progress evaluation, but also provides a targeted adjustment plan in case of abnormal progress, which helps to optimize the project progress and avoid further delays.

[0016] (2) When evaluating the progress of the landscaping project, the present invention realizes a detailed division of progress management in terms of time by subdividing the entire construction period into different construction stages and demarcating an evaluation period for each construction stage. This greatly enhances the timeliness and effectiveness of progress management, thus largely avoiding the accumulation of abnormal progress. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Refer to Figure 1As shown in the figure, the present invention proposes a comprehensive evaluation and analysis system for the process of landscaping projects based on data fusion, including a greening project planning information acquisition module, a material supply plan construction module, a meteorological prediction construction module, a planning process construction module, a planned construction personnel determination module, a construction monitoring module, a construction process compliance evaluation module, and a construction process anomaly handling module. Among them, the greening project planning information acquisition module is respectively connected to the material supply plan construction module and the meteorological prediction construction module, the material supply plan construction module and the meteorological prediction construction module are respectively connected to the planning process construction module, the planning process construction module is connected to the planned construction personnel determination module, the construction monitoring module and the planning process construction module are both connected to the construction process compliance evaluation module, and the construction process compliance evaluation module, the construction monitoring module, and the planned construction personnel determination module are all connected to the construction process anomaly handling module.

[0022] The greening project planning information acquisition module is used to obtain the planned tree and shrub species for the landscaping project, the planned construction stages, the planned time periods for each construction stage, and the planned construction volume.

[0023] In the specific implementation of the above solution, the construction stages of the landscaping project are generally divided into three stages: site preparation, infrastructure construction, and greening planting. Each construction stage has its specific construction tasks. Among them, the construction task of site preparation is to remove sundries, construction waste, and other obstacles in the area to be greened, and level the ground; the construction task of infrastructure construction is to lay water supply and drainage pipes, install water supply and drainage facilities, and build hard landscape elements such as flower beds, benches, and sculptures; the construction task of greening planting is to plant trees and shrubs according to the design drawings, including digging pits, planting, and fixing, laying turf or sowing grass seeds to form a lawn.

[0024] In a further implementation, the planned time periods for each construction stage are extracted from the construction design documents, and the planned construction volume for each construction stage can be determined based on the construction tasks of each stage. Exemplarily, the planned construction volume for the site preparation stage is determined based on the area of the area to be greened, the coverage of obstacles such as sundries and garbage, and the levelness of the land. Specifically, it can be quantitatively determined by constructing a three-dimensional image of the current state of the area to be greened and using a computer model.

[0025] In another example, the planned construction volume for the greening planting stage can be quantitatively determined by importing the greening design plan drawings, including tree and shrub species, the number of trees and shrubs to be planted, the distribution positions of the trees and shrubs, the planting methods of the trees and shrubs, and the turf laying area, into the computer model using a computer model.

[0026] The material supply plan construction module is used to count the types of materials required for each construction stage, which can be extracted from the construction design documents, and then construct a planned material supply schedule for each construction stage based on the material supply contract.

[0027] As a specific embodiment of the above solution, the material categories required in each construction stage are specifically as follows: The material categories required in the site preparation stage include, but are not limited to, topographic survey tools such as bulldozers, excavators, levels, and total stations. The material categories required in the infrastructure construction stage include, but are not limited to, pipes, valves, sprinklers, etc. for drainage laying, and reinforced concrete, wood, stone, etc. for landscape construction. The material categories required in the greening planting stage include, but are not limited to, greening materials such as seedlings and turf, and fixed seedling materials such as tree support poles and binding tapes.

[0028] In the optimized implementation of the above solution, the process of constructing the planned material supply schedule for each construction stage is as follows: Extract the agreed delivery times corresponding to various materials required in each construction stage from the material supply contract.

[0029] It should be noted that the agreed delivery time of materials is generally signed in the contract when signing the material supply contract.

[0030] Create a material supply schedule template, and fill in the agreed delivery times of various materials in each construction stage in the schedule template to form the planned material supply schedule for each construction stage.

[0031] In an example, assuming that the planned period corresponding to the greening planting stage is from June 1st to July 30th, the material supply schedule template corresponding to the greening planting stage is shown in Table 1.

[0032] Table 1

[0033]

[0034] The meteorological prediction construction module is used to construct the predicted meteorological schedule for each construction stage based on the planned period of each construction stage using the meteorological platform. See the following process: Extract the time series meteorological information of the planned period in which each construction stage is located from the meteorological platform. Among them, meteorological information can extract meteorological parameters that have a greater impact on the project, such as temperature, humidity, precipitation, and wind speed. Since the construction tasks of each construction stage are different, the meteorological information concerned may not be the same. Therefore, the meteorological information extracted for each construction stage can be different.

[0035] In the exemplification of the above solution, the meteorological information concerned in the site preparation stage can be wind speed and rainfall. The amount of rainfall directly affects the soil humidity and construction conditions. Excessive precipitation may cause the site to be muddy, affecting the normal operation of construction machinery and the leveling of the site. Strong winds may pose a threat to the safety of the construction site, especially during site cleaning and mechanical operations.

[0036] In another example, the meteorological information concerned in the infrastructure construction stage can be rainfall, temperature, humidity, etc. Among them, rainfall may have an adverse impact on foundation excavation and concrete pouring. Concrete may not cure well in a humid environment, and precipitation may also cause waterlogging in the excavation pit; extreme high or low temperatures will affect the curing quality of concrete. In a low-temperature environment, heating measures may be required for concrete to avoid frost cracking; while in a high-temperature environment, cooling measures may be needed to prevent excessive water evaporation. Humidity has an important impact on the curing process of concrete. High humidity helps the curing of concrete, but over-wetting also needs to be avoided; low humidity may accelerate the drying of concrete and affect its strength.

[0037] In yet another example, the meteorological information concerned in the greening planting stage can be temperature, humidity, light intensity, wind speed, etc. Among them, temperature affects the growth and transplant adaptability of plants. Excessively high or low temperatures may affect the growth state of plants. Especially during transplantation, when the temperature fluctuates greatly, plants may require additional protection measures. Humidity affects the dryness and wetness of the soil and the water requirements of plants. High humidity is beneficial to the growth of plants, but an over-wet environment may cause root problems. Low humidity may require increased irrigation to meet the needs of plants. Strong winds may damage newly planted plants and affect their stability. Especially when they are newly planted, strong winds may cause plants to shift or be damaged. Light intensity is a necessary condition for the normal growth of plants, but different plants have different light requirements. Some plants require full sunlight, while others are suitable for partial sunlight or shady environments.

[0038] In the specific implementation of the above solution, according to the location coordinates of the project site, a request is sent to the meteorological service platform to obtain the time-series meteorological information for the planned time periods of each construction stage.

[0039] It should be understood that obtaining the time-series meteorological information ensures that the data obtained covers every day within the project planning period, forming a time series.

[0040] Create a meteorological time schedule template, and fill in the time-series meteorological information for the planned time periods of each construction stage in the time schedule template according to the time series to form the predicted meteorological time schedule for each construction stage.

[0041] In a specific example, the meteorological time schedule template corresponding to the greening planting stage is shown in Table 2.

[0042] Table 2

[0043] Date Maximum Temperature Minimum Temperature Humidity Light Intensity Wind Speed June 1st 28℃ 15℃ 20％ 50000lx 4m / s June 2nd 30℃ 12℃ 40％ 65000lx 10m / s June 3rd 26℃ 10℃ 25％ 10000lx 8m / s June 4th 32℃ 17℃ 42％ 80000lx 1m / s June 5th 24℃ 14℃ 30％ 8000lx 3m / s

[0044] The planning process construction module is used to determine the suitable meteorological information for each construction stage, and thus fuse the planned material supply schedule and the predicted meteorological schedule for each construction stage to construct the planning process schedule for each construction stage.

[0045] As an optimal implementation mode, the suitable meteorological information for each construction stage can be extracted from the construction design documents.

[0046] Furthermore, the construction of the planning process schedule for each construction stage is implemented as follows: Extract the last agreed delivery time from the planned material supply schedule for each construction stage as the material supply deadline for each construction stage.

[0047] It should be noted that the last agreed delivery time is the latest time point in the material supply schedule, at which all the materials required for the corresponding construction stage are supplied.

[0048] Intercept the time series meteorological information after the material supply deadline from the predicted meteorological schedule for each construction stage, and compare it with the suitable meteorological information for this construction stage, and count the meteorological suitability of each construction stage in the time series. The statistical calculation of the meteorological suitability can set a weight value for each meteorological item, then perform a proximity score for each meteorological item according to the time series meteorological information and the suitable meteorological information, and finally perform a weighted average calculation by combining the proximity score of each meteorological item with the weight value of each meteorological item to obtain the meteorological suitability.

[0049] It should be explained that the reason for intercepting the time series meteorological information after the material supply deadline for meteorological suitability analysis is mainly because construction operations must be carried out after the material supply is completed. Only after the materials arrive can the specific construction work begin, and the meteorological conditions at this time will directly affect the quality and efficiency of the construction process. Therefore, analyzing the meteorological information during the period after the material supply is completed is more valuable and helps to more accurately evaluate and optimize the environmental suitability of the construction stage.

[0050] Compare the meteorological suitability of each construction stage in the time series with the standard meteorological suitability set by the system. If the meteorological suitability of a certain construction stage on a certain date reaches the standard meteorological suitability, then take this date as the planned effective construction date.

[0051] It should be added that the standard meteorological suitability can be set according to project requirements. The higher the standard meteorological suitability is set, the fewer the number of planned effective construction dates that may reach the standard meteorological suitability. Given a certain planned construction volume, more construction workers will be required at this time, and the overall construction allocation will be relatively generous. On the contrary, if the standard meteorological suitability is set lower, the number of planned effective construction dates that reach the standard meteorological suitability will be relatively more, the number of planned construction workers will be less, and the overall construction allocation will be relatively strict.

[0052] Count the number of planned effective construction dates in each construction stage, and combine the planned construction volume of each construction stage with the number of planned effective construction dates to obtain the planned construction volume of each construction stage on each planned effective construction date. Specifically, the planned construction volume can be evenly distributed to each planned effective construction date to obtain the planned construction volume of each construction stage on each planned effective construction date.

[0053] Create a process schedule template, and fill in the planned construction volume of each construction stage on each planned effective construction date in the process schedule template in chronological order of dates to form the planned process schedule of each construction stage.

[0054] In the example where the planned period corresponding to the greening planting stage is from June 1st to July 30th, assume that the time series after the material supply cut-off time is from June 10th to July 30th. Among them, the planned effective construction dates screened according to the meteorological suitability are June 12th, June 14th, June 15th, June 17th, June 18th, June 20th, etc. The number of planned effective construction dates counted is 25. Assume that the planned construction volume of the greening planting stage is 100 units. Then the planned construction volume on each planned effective construction date is 4 units. The planned process schedule in this example is shown in Table 3.

[0055] Table 3

[0056] Date Planned Construction Quantity (Unit) June 10th 0 June 11th 0 June 12th 4 June 13th 0 June 14th 4 June 15th 4 June 16th 0

[0057] The said planned construction personnel determination module is used to determine the planned construction personnel of each construction stage based on the planned process schedule of each construction stage, specifically as follows: Divide the planned construction volume of each construction stage by the number of planned effective construction dates to obtain the planned daily average construction volume of each construction stage.

[0058] Retrieve the construction records of similar landscaping projects in historical construction, and extract the daily construction volume of a single construction personnel in each construction stage as the unit construction volume of each construction stage.

[0059] It should be added that in actual construction, the daily construction volume of a single construction personnel may be affected by various factors. Therefore, a certain margin can be left based on experience to make the planned construction personnel of each construction stage more sufficient.

[0060] Divide the planned daily average construction volume of each construction stage by the unit construction volume of the corresponding construction stage and then round up to obtain the planned construction personnel of each construction stage.

[0061] The construction monitoring module is used to create a construction log during the construction of a landscaping project. The construction party uploads construction data and material supply data in real time at each construction stage. The construction data includes the actual construction date, actual construction volume, and actual number of construction workers. The material supply data is the actual delivery time of various materials. At the same time, meteorological information is monitored in real time at each construction stage. Then, based on the uploaded construction data, material supply data, and meteorological information, the actual progress schedule, material supply schedule, and meteorological schedule for each construction stage are constructed.

[0062] It should be understood that in construction monitoring, by creating a construction log and having the construction party upload construction data in real time at each construction stage, compared with manual monitoring, it can improve the timeliness of construction data monitoring. At the same time, by digitally recording the construction log, it reduces errors and omissions in manual recording, ensuring data accuracy. In addition, the construction log system can standardize the format and content of data recording, ensuring the consistency and integrity of all data.

[0063] In a specific example of the above solution, the process of constructing the actual progress schedule, material supply schedule, and meteorological schedule for each construction stage is as follows: Fill in the construction date and construction volume in the construction data uploaded at each construction stage into the progress schedule template to form the actual progress schedule for each construction stage.

[0064] Fill in the material supply data uploaded at each construction stage into the material supply schedule template to form the material supply schedule for each construction stage.

[0065] Fill in the meteorological information monitored in real time at each construction stage into the meteorological schedule template to form the meteorological schedule for each construction stage.

[0066] The implementation of the above project progress assessment at each construction stage is shown in Figure 2 as follows.

[0067] The construction process compliance assessment module is used to determine the assessment period based on the planned period of each construction stage. From the planned progress schedule and actual progress schedule of the corresponding construction stage, the planned progress sub-schedule and actual progress sub-schedule belonging to each assessment period are intercepted for construction process compliance assessment.

[0068] As a preferred implementation, determining the assessment period based on the planned period of each construction stage is achieved as follows: Statistically calculate the duration t i of the planned period corresponding to each construction stage and the number x i of required material categories, and substitute them into the formula to obtain the construction complexity CC i of each construction stage, where i represents the construction stage number, i = 1, 2,......, n, and e represents the natural constant.

[0069] Select half of the shortest duration among the durations corresponding to the planning periods of each construction stage as the upper limit evaluation period.

[0070] Combine the construction complexity of each construction stage with the upper limit evaluation period T using the formula Calculate the evaluation period ΔT for each construction stage i , where represents the upper value.

[0071] It should be understood that when determining the evaluation period of each construction stage, it is not a fixed duration as the evaluation period, but the construction complexity statistically obtained based on the planned duration of the construction stage and the quantity category of required materials. The greater the construction complexity, the shorter the evaluation period. In this way, multiple evaluation periods can be obtained for construction progress adjustment.

[0072] When evaluating the progress of a landscaping project, the present invention divides the entire construction period into different construction stages in detail and delimits the evaluation period for each construction stage, realizing a detailed division of progress management in terms of time. It can leave a certain amount of time for adjustment according to the current process status during the process of the construction stage, which greatly enhances the timeliness and effectiveness of progress management, thus largely avoiding the accumulation of progress anomalies.

[0073] In a further optimized implementation, the construction process compliance evaluation refers to the following process: Classify and accumulate the planned construction quantities and actual construction quantities filled in the planned process sub-tables and actual process sub-tables belonging to each evaluation period of each construction stage to obtain the total planned construction quantity and total actual construction quantity of each construction stage in each evaluation period, and make a comparison. If the total actual construction quantity of a certain construction stage in a certain evaluation period is less than the total planned construction quantity, then record this construction stage and this evaluation period as the abnormal evaluation period of the abnormal construction stage.

[0074] It should be emphasized that since the impact of process lag is greater than that of process advance, the present invention mainly focuses on the identification and analysis of process lag when identifying process anomalies.

[0075] The construction process anomaly processing module is used to identify and trace the anomaly direction and determine the anomaly adjustment direction in combination with the correlation schedule of material supply and meteorology when evaluating the construction process anomaly.

[0076] Specifically, the anomaly direction identification and tracing are as follows: Extract the planned effective construction date, planned construction quantity, actual construction date, and actual construction quantity from the planned process sub-table and actual process sub-table belonging to the abnormal evaluation period of the abnormal construction stage respectively, and map and match the planned effective construction date with the actual construction date, and count the ratio of the number of unmatched construction days to the total number of effective construction days as the construction day anomaly ratio. Specifically, divide the number of unmatched construction days by the number of effective construction days to obtain the construction day anomaly ratio.

[0077] Compare the actual construction volume with the planned construction volume for the successfully matched construction dates, and select the ratio of the number of construction days with actual construction volume lower than the planned construction volume to the number of successfully matched construction days as the abnormal construction volume ratio. The abnormal construction volume ratio is calculated by dividing the number of construction days with actual construction volume lower than the planned construction volume by the number of successfully matched construction days.

[0078] It should be noted that the above-mentioned construction days with failed matches are the construction days that did not actually carry out construction relative to the planned effective construction dates in the planned progress sub-table, and the construction days with successful matches are the construction days that actually carried out construction relative to the planned effective construction dates in the planned progress sub-table.

[0079] Compare the abnormal construction day ratio and the abnormal construction volume ratio with the set thresholds respectively. Exemplarily, the set threshold for the abnormal ratio is 0.8. If the abnormal construction day ratio reaches the set threshold, the abnormal indication is that the construction day has not started. If the abnormal construction volume ratio reaches the set threshold, the abnormal indication is insufficient construction volume.

[0080] When the abnormal indication is that the construction day has not started, extract the construction days with failed matches from the actual progress sub-table as the first abnormal construction days, and intercept the corresponding material supply time sub-table and meteorological time sub-table of the abnormal evaluation period from the material supply schedule and meteorological schedule of the abnormal construction stage. Then, extract whether the abnormal construction days are in the material supply period and meteorological information from the corresponding sub-tables, and calculate the meteorological suitability based on the meteorological information. If the first abnormal construction day is in the material supply period or the meteorological suitability does not reach the standard meteorological suitability, where when the first abnormal construction day is in the material supply period, it means that the material supply has not been completed on that construction day, indicating that the material supply lag leads to the inability to carry out construction. When the meteorological suitability of the first abnormal construction day does not reach the standard meteorological suitability, it means that the meteorological conditions on that day do not meet the construction requirements, resulting in the inability to carry out construction. Then, trace the reason for the non-start of the first abnormal construction day to the construction environment obstacle, indicating that there are changes in the material supply plan or meteorological prediction, and the accuracy is insufficient. Otherwise, trace the reason for the non-start of the first abnormal construction day to human factors.

[0081] When the abnormal indication is insufficient construction volume, extract the construction days with actual construction volume lower than the planned construction volume from the actual progress sub-table as the second abnormal construction days, and intercept the corresponding material supply time sub-table and meteorological time sub-table of the abnormal evaluation period from the material supply schedule and meteorological schedule in the abnormal construction stage. Similarly, obtain whether the second abnormal construction days are in the material supply period and the meteorological suitability from the corresponding sub-tables. At the same time, extract the comparison between the actual number of construction workers and the planned number of construction workers in the abnormal construction stage from the construction data of the construction log uploaded on the second abnormal construction days. If the second abnormal construction days are in the material supply period or the meteorological suitability does not reach the standard meteorological suitability or the actual number of construction workers is less than the planned number of construction workers, trace the reason for the insufficient construction volume on the second abnormal construction days to construction environment obstacles. Otherwise, trace the reason for the insufficient construction volume on the second abnormal construction days to human factors.

[0082] It should be explained that when the abnormal indication is insufficient construction volume, when identifying construction environment obstacles, the comparison of the number of construction workers is added compared with when the construction day has not started, because if the number of construction workers is insufficient, it will greatly affect the construction volume.

[0083] It also needs to be explained that human factors are exemplarily idling, occurrence of safety accidents, non-standard construction, etc.

[0084] Furthermore, the abnormal adjustment direction is determined as follows: (1) When it is traced that there are construction environment obstacles in the abnormal evaluation period of the abnormal construction stage, reconstruct the planned material supply schedule and predicted meteorological schedule for the next evaluation period, which can improve the accuracy of plan prediction creation, and accordingly perform dynamic update of the corresponding planned progress schedule in the abnormal construction stage.

[0085] (2) When it is traced that there are human factors in the abnormal evaluation period of the abnormal construction stage, strengthen on-site monitoring of construction workers in the next evaluation period, which can timely discover and solve problems, and can avoid further expansion of problems, resulting in greater schedule delays.

[0086] The above content is only an example and explanation of the concept of the present invention. Those skilled in the art of this technology make various modifications or supplements to the described specific embodiments or use similar methods to replace them, as long as they do not deviate from the concept of the invention or exceed the scope defined by the present invention, they should all belong to the protection scope of the present invention.
