Further, in one possible example, the step 23 of performing model quality evaluation on each of the at least one target prediction model to obtain at least one target evaluation value may include the following steps:

231. determining evaluation values of a target prediction model i in multiple dimensions to obtain multiple evaluation values, wherein the target prediction model i is any target prediction model in the at least one target prediction model;

232. determining the weight corresponding to each dimension in the plurality of dimensions to obtain a plurality of weights;

Further, the step 41 of screening the plurality of suggestions to obtain at least one target suggestion may include the following steps:

411. Obtaining the evaluation of a suggestion j, and obtaining a plurality of evaluations, wherein the suggestion j is any suggestion in the plurality of suggestions;

when the ratio is greater than a preset threshold, reserving the suggestion j;

414. and discarding the suggestion j when the ratio is smaller than or equal to the preset threshold.

The preset threshold value can be set by the user or default by the system. In a specific implementation, taking any suggestion j as an example, the suggestion j is any suggestion in a plurality of suggestions, the electronic device obtains the evaluation of the suggestion j to obtain a plurality of evaluations, and as a plurality of item members evaluate the suggestion, the number of good comments and the number of bad comments in the plurality of evaluations can be determined, and in a specific implementation, the number of good comments and the number of bad comments can be realized through semantic recognition, and further, the ratio between the number of good comments and the number of bad comments can be determined, when the ratio is greater than a preset threshold, the suggestion j is reserved, and when the ratio is less than or equal to the preset threshold, the suggestion j is abandoned, so that the suggestion choice can be realized through a voting mechanism, and the accuracy of the suggestion can be ensured.

In the illustration, the application of BIM in engineering example is taken as an example, the dust removing system and the crude gas system of a certain steel plant are modified greatly, and the original pipeline with the diameter of 3900mm from the elevation of 96.3 m-64 m is replaced by a 4000mm pipeline. The gas pipe enters the dust remover from the original top access to the side tangential access of the dust remover, and is tangentially connected with the dust remover after the access mode is changed into a square 4300mmxl800ram from 4000 mm. The gravity dust collector is changed into a cyclone dust collector with the diameter of 8000m and the diameter of 16000mm of the supporting shell. The elevation of the pipeline connected with the washing tower is changed from 41m to 63m. The related small pipelines, ash removing equipment, maintenance platforms and brackets are correspondingly modified. Wherein, the main engineering amount is as follows: the gravity dust collector is about 60t, the cyclone dust collector is about 160t, the pipeline weight is 105t, and the platform and steel ladder are about 115t. In the project, the visual communication of BIM is utilized to communicate with the first party, understanding ambiguity is accurately and clearly reduced, modeling is performed by utilizing BIM software TEKLA, the model can accurately express the elevation of each platform, the position of the maintenance platform, the clearance of each position and the trend of the stair platform. The first party, the process specialty and the structure specialty together determine the details in the whole project including the setting of the platform and the walkway through the three-dimensional model. When the communication is carried out with the first party, a three-dimensional model is adopted, and the communication is intuitive and accurate. The proposal is quickly determined, the doubt points in the proposal are eliminated, the bifurcation points are eliminated, and the requirements of the first party are clearly and accurately understood. Lays a foundation for the detailed design, avoids the design quality problem and avoids the loss caused by reworking.

Further, where the relationship of certain components is very complex, for example, there are large brackets supporting the delivery tubes, there are walkways trusses from the shaft frame to the dust collector, there are walkways and platforms around the dust collector, and steel ladders connecting the shaft walkways to the dust collector walkway platforms. To ensure that each walkway can be smoothly walked through, it is difficult to ensure that the installation is free from problems through two-dimensional representation. The block has limited space position and is intersected with each other on the vertical surface. The relationship to each other, let alone the exact headroom. Therefore, the first party does not directly put the upper steel ladder on the truss, the steel ladder is required to be provided with the support, the project can be intuitively understood through BIM modeling, and if the steel ladder is provided with the support alone, a person can certainly bump from the steel ladder, and the person does not need to bend down to go. Therefore, the bracket is removed and directly overlapped on the truss.

Furthermore, the first party needs to cancel the support of the large support in order to ensure the smoothness of the furnace body channel, and the large support is the only fulcrum of the raw gas pipeline, which is important, the support is 16m high and 8m wide, after canceling the support, the support can only be made into a rigid frame, the cross section can be greatly enlarged, the support is originally acted on the steel shell, the larger the cross section is, the larger the required support surface is, the larger the damage to the steel shell is, and the my party does not agree to cancel the support. Through the lofting of the TEKLA, the support can be clearly seen and the passage of the channel is not hindered, a person can easily pass through the support, and finally, the first party agrees to the scheme that the support is reserved by the support.

In practice, after BIM communication, each detail is confirmed, and a meeting summary is signed, so that the details are taken as the basis of detailed design, and barriers are cleared for later detailed design and processing and manufacturing. After the two sites are installed on site, the two sites are almost identical to the three-dimensional model, the traffic of people is not affected, and the stress is ensured.

In addition, each component is accurately positioned through a parameterized model, and the machining and manufacturing size of the steel structure are strictly controlled. Through pre-assembly in the computer and coordinated collision inspection, the problems of collision and the like when components are installed on site are avoided, the problems of collision and installation failure in site construction are reduced, and the construction speed and the construction quality are improved. And then the drawing provides a detailed and accurate construction drawing for the first party and the construction unit. The drawings include component positioning, bolt hole positions, detailed dimensions of each component, etc., detailed bill of materials, etc.

For irregular structures, the TEKLA can accurately design and create complex three-dimensional models of steel structures of arbitrary dimensions. Nodes are also created in the model, and can be checked from three dimensions and various views, so that each node is ensured; and good certainty. Through the pre-assembly simulation, the positions of each component, the positions of holes, the positions of stiffening and the positions of the gusset plates can be accurately placed.

After the model is built, software automatically generates a layout, a component diagram and a part diagram. And can ensure 100% accuracy of the drawing. The size of each gusset plate, the length of each member, the bolt hole, the weld joint and the like are all automatically generated, and the size is accurate to millimeter. If the nodes or components in the model are modified, the drawings are automatically modified and marked. Repeated drawing of the designed drawing is not needed, and mistakes caused by human factors are not worried. And the reworking of site construction caused by design errors is avoided.

To sum up, the project is a reconstruction project, mainly replacing large-scale equipment, the existing building is not dismantled, the three building raw gas dust removal systems are newly built after being dismantled, the right hot blast stove system utilizes the original factory building, the lower main factory building also utilizes the existing factory building, the uppermost road is 5m wide, the two sides of the road are pipelines, and the clearance is limited to 5m. The equipment of the main factory building and the equipment of the hot blast stove system are replaced, so that the area surrounded by the middle is a hoisting temporary parking area, and the equipment to be installed by the three systems is hoisted through the area, so that the area cannot be occupied for a long time, and only II potters B and J occupy 1 day. Therefore, the construction sites of project accessories are limited, the construction period is very short, and according to the construction plan, many structures are integrally hoisted after the construction sites are assembled. Thus, the construction site is required to be sufficiently close to the project that the crane can be suspended to the component; or the components may be small enough to be transported by car to a temporary lifting point. According to the conditions, a construction site is set at the left side of a main factory building, and the pillars and the supporting vehicles are transported to the site and installed on site: the shell is hoisted in three sections, the upper part 3m of the column top is a first section, the rest upper part is a second section, and the suspended pipe is a third section. The smallest three components are 20.534m long, 4.16m wide and 19.78m high; the large diameter 16m and the auxiliary components such as a ladder are 18m and the height is 24.239m, so that crane resources can be comprehensively arranged for smooth hoisting operation, and high requirements are provided for the accuracy, rationality, high efficiency and reliability of the hoisting scheme design. If a manual calculation selection mode is adopted, the workload is large, the method is not visual, and the accuracy, the efficiency and the feasibility of the scheme are affected. In order to ensure reasonable and efficient hoisting scheme, project utilization REVIT and naviswork adopt three-dimensional simulation hoisting scheme.

In the concrete implementation, station simulation is mainly performed, the optimal station point and the optimal station position area of the crane are determined by selecting the working radius range of the crane, the initial position and the positioning position of the component, the counterweight area of the crane and the rotation range of the crane are simulated, the occurrence of collision is avoided, and the condition that clamping rods and overload of the crane cannot occur in the range is ensured. Through the movement, lifting, luffing and rotation actions of a real simulation crane, the model is watched from multiple angles through front view, overlook view, side view and other views, and the possible collision in the simulation process is rapidly found through the observation of different angles. And carrying out construction simulation in a virtual environment before construction, finding problems in advance, and ensuring the smooth hoisting construction.

For example, the hoisting scheme is finally determined by BIM software simulation as follows: the crane station is located main building below, adopts 200 t's tank crane, and the preparation place is located main building left side, and the hoist and mount scope of davit just can cover preparation place and mounted position to can be through the removal of track, the coverage of proper adjustment hoist and mount davit. And finally, the hoisting is smoothly carried out in place, which indicates that the hoisting position is reasonably selected, the hoisting equipment is reasonably selected, and the cost is completely within the budget.
