The work package management technology is a method for uniformly executing and managing a plurality of work units/tasks with high dependence degree by packaging the work units/tasks into a whole. The work package management technology can realize scale effect and reduce the management cost of resource repeated scheduling. The prefabricated building is formed by assembling prefabricated parts on a construction site. The work package management technology used in the production process of the assembly type building mainly depends on the work experience of a project manager, and the reliability of the work package distribution result is difficult to guarantee.
In view of the above-mentioned drawbacks of the prior art, the present invention provides a method for generating a work package of an assembly type building, the method comprising: acquiring a building information model and an integral process flow chart corresponding to the assembly type building, wherein the building information model comprises component units corresponding to a plurality of prefabricated parts respectively; determining local process information and neighborhood process information respectively corresponding to each component unit according to the building information model and the overall process flow diagram; clustering each component unit according to the local area process information and the neighborhood process information of each component unit to obtain a plurality of clustering clusters; and determining a sub-packaging strategy corresponding to the fabricated building according to each clustering cluster, wherein the sub-packaging strategy is used for generating a plurality of work packages, and each component unit in the same work package is jointly managed. According to the method, the work package distribution result of the assembly type building is automatically generated without manual intervention by analyzing the building information model and the whole process flow diagram of the assembly type building. The problem of use work package management technique mainly rely on project manager's work experience in the production process of assembly type structure at present, be difficult to guarantee the reliability of work package distribution result is solved.
As shown in fig. 1, the method includes:
s100, obtaining a building information model and an integral process flow chart corresponding to the assembly type building, wherein the building information model comprises component units corresponding to a plurality of prefabricated component parts respectively;
s200, determining local process information and neighborhood process information respectively corresponding to each component unit according to the building information model and the overall process flow diagram;
s300, clustering each component unit according to the local area process information and the neighborhood process information of each component unit to obtain a plurality of clustering clusters;
and S400, determining a sub-packaging strategy corresponding to the assembly type building according to each cluster, wherein the sub-packaging strategy is used for generating a plurality of work packages, and each component unit in the same work package is managed jointly.
Specifically, the building information model is composed of a plurality of component units, each of which represents one prefabricated component constituting the fabricated building. The whole process flow chart comprises the process flow of all prefabricated parts, all the prefabricated parts required by the prefabricated building can be produced according to the whole process flow chart, and the prefabricated building is assembled by the prefabricated parts. In order to improve the production efficiency of the prefabricated building, the embodiment needs to use the work package management technology in the production process of the prefabricated parts, package a plurality of highly dependent process flows into a whole, and implement and manage the process flows uniformly. For each component unit, local process information and neighborhood process information of the component unit are determined based on the building information model and the overall process flow diagram. And then clustering each component unit according to the local domain process information and the neighborhood process information to obtain a plurality of cluster clusters. The distribution positions of all the parts in the same cluster in the model are similar, and the process characteristics are similar, so that the sub-package strategy of the work package can be accurately generated based on all the clusters. All the parts in the same work package are managed jointly, and the production efficiency of the fabricated building can be greatly improved.
In one implementation, the method for determining the local process information and the neighborhood process information respectively corresponding to each component unit includes:
step S201, determining a local process flow diagram corresponding to the component unit according to the overall process flow diagram, and using the local process flow diagram of the component unit as the local process information of the component unit;
step S202, determining a plurality of neighborhood component units corresponding to the component unit according to the building information model;
step S203, determining local process flow charts corresponding to the neighborhood component units respectively according to the overall process flow chart;
step S204, according to the local process flow chart of each neighborhood component unit, determining the neighborhood consistency of the component unit, and taking the neighborhood consistency as the neighborhood process information of the component unit.
Specifically, for each component unit, a local process flow diagram related to the component unit in the overall process flow diagram is intercepted, and local process information of the component unit is obtained. And determining the component units in the neighborhood of the component through the building information model to obtain a plurality of neighborhood component units corresponding to the component units. In one implementation, the neighborhood may be determined based on a predetermined distance or a predetermined range. And then respectively intercepting local process flow charts related to the neighborhood component units in the overall process flow chart, and judging the overall similarity degree of the local process flow charts of the neighborhood component units to obtain the neighborhood consistency of the component units, wherein the higher the overall similarity degree is, the higher the neighborhood consistency is. And finally, taking the neighborhood consistency as neighborhood process information of the component unit. In short, the process information in the present domain reflects the process characteristics of the component unit itself, and the process information in the neighborhood reflects the degree of similarity of the process characteristics of the component units around the component unit.
In one implementation, the overall process flow diagram includes a plurality of process units, for example, when the fabricated building is a steel structure module room, the overall process flow diagram includes process units of steel material loading, cutting, bending, welding, polishing, and the like. Each process unit has specific production tasks, resource types, usage, functional attributes, such as welding including spot welding, full welding, repair welding, etc. The process units are connected by connecting lines with arrow directions and used for reflecting the execution sequence (space-time relation) among the processes.
In an implementation manner, the step S204 specifically includes:
step S2041, determining a fusion process flow chart according to the local process flow chart of each neighborhood component unit;
step S2042, obtaining a local process flow diagram of each neighborhood component unit and a deviation value of the fusion process flow diagram respectively;
step S2043, determining the neighborhood consistency according to each deviation value.
Specifically, determining the overall similarity degree of each local process flow diagram by sequentially comparing two local process flow diagrams consumes a large amount of calculation overhead, so in this embodiment, image fusion is performed on each local process flow diagram to obtain a fusion process flow diagram. Because the fusion process flow chart contains the image characteristics of each local process flow chart, the local process flow charts are only needed to be compared with the fusion process flow chart respectively to obtain deviation values of the local process flow charts and the fusion process flow chart, the overall similarity degree of the local process flow charts can be determined through all the deviation values, and the neighborhood consistency is obtained.
In one implementation, the clustering process of each of the component units includes:
step S301, determining local characteristics of the component unit according to the local process information of the component unit;
step S302, local domain characteristics of a previous clustering component unit are obtained, and the characteristic similarity of the local domain characteristics of the previous component unit and the local domain characteristics of the component unit is calculated;
step S303, judging whether the feature similarity is higher than a similarity threshold, and when the feature similarity is higher than the similarity threshold, incorporating the component unit into the current cluster;
step S304, judging whether the neighborhood consistency of the component unit is higher than a consistency threshold value, and when the neighborhood consistency of the component unit is higher than the consistency threshold value, incorporating each neighborhood component unit corresponding to the component unit into the current cluster.
Specifically, the conventional clustering method analyzes and clusters each component unit in turn, and once the number of the component units is too large, a large amount of time cost is consumed. Therefore, the embodiment adopts an improved clustering method, for each component unit, feature extraction is performed on the basis of the local domain process information of the component unit to obtain local domain features, then the local domain features of the component unit are compared with the local domain features of a previous component unit (i.e., a previous component unit incorporated into the current cluster), and if the feature similarity is higher than the similarity threshold, it indicates that the process features of the component unit are similar to the process features of the previous component unit, the component unit is incorporated into the current cluster. And detecting neighborhood consistency of the component unit, and if the neighborhood consistency is higher than a preset consistency threshold value, indicating that the process characteristics of all the component units in the neighborhood of the component unit are highly similar, directly incorporating all the component units in the neighborhood of the component unit into the current cluster without cluster analysis. And then taking the nearest component unit outside the neighborhood of the component unit as the next component unit for clustering.
In one implementation, a repository may be constructed in advance to store the local process information and the neighborhood process information of each of the component units. In actual application, local area process information and neighborhood process information of the component unit are obtained from the storage library based on the component name.
In one implementation, the local domain features of the component units may be represented using a numerical vector output by a pre-trained semantic model. The pre-training semantic model is trained in advance, distance similarity cosine calculation is carried out according to the numerical vectors output by the model and the real numerical vectors during training, and model parameters are updated through similarity difference back propagation.
In one implementation, the method further comprises:
and S305, when the neighborhood consistency of the component unit is lower than or equal to the consistency threshold, taking the neighborhood component unit of the component unit as a next component unit for clustering.
Specifically, if the neighborhood consistency of the component unit is lower than or equal to the consistency threshold, it indicates that the difference between the process characteristics of each component unit in the neighborhood of the component unit is large, and in order to ensure the reliability of the distribution result of the work package, batch clustering is not suitable, and the neighborhood component units of the component unit need to be clustered in sequence.
In one implementation, the step S400 specifically includes:
s401, inputting each clustering cluster into an agent to obtain an initial sub-packaging strategy;
step S402, managing the production process of the fabricated building based on the initial sub-package strategy through a simulation technology, and randomly interfering the production process of one component unit;
step S403, acquiring the abnormal detection duration of the production process of the interfered component unit;
step S404, judging whether the abnormal detection time length is less than a preset time length;
step S405, when the abnormal detection duration is greater than or equal to the preset duration, determining the reward value of the intelligent agent according to the abnormal detection duration;
and S406, updating parameters of the intelligent agent according to the reward value, and continuing to execute the step of inputting each cluster into the intelligent agent until the abnormal detection time length is less than the preset time length to obtain the sub-packet strategy.
In this embodiment, an agent is pre-constructed, and the agent may automatically generate a corresponding sub-packaging policy based on a plurality of input clustering clusters, and perform simulation detection based on the generated sub-packaging policy to evaluate the quality of the sub-packaging policy. And then calculating the reward value according to the evaluation result, and automatically updating the parameters of the intelligent agent through the reward value so as to expect to obtain a higher reward value next time. Through multiple rounds of parameter updating, the output result of the intelligent agent is more and more reliable, and finally a better sub-package strategy can be output. Specifically, each cluster is input into the agent to obtain an initial subpackaging strategy, and the initial subpackaging strategy is low in reliability because the agent is not trained at the moment. Managing the production process of the fabricated building based on an initial sub-package strategy through a simulation technology, randomly selecting the production process of one component unit for interference, and calculating the time interval from interference to abnormal detection in the production process of the component unit, namely the abnormal detection time. When the anomaly detection duration is longer than or equal to the preset duration, the process flows of all the component units are managed jointly according to the initial sub-packaging strategy, the anomaly cannot be detected in time, and the initial sub-packaging strategy needs to be further improved. And then determining the reward value of the intelligent agent according to the abnormal detection duration, so that the intelligent agent automatically updates the parameters based on the reward value. And repeating the steps until the abnormal detection time length is less than the preset time length, indicating that the currently obtained subpackage strategy meets the management requirement and taking the obtained subpackage strategy as a final subpackage strategy.
In one implementation, the method further comprises:
s500, acquiring the number of updating rounds of the agent;
step S501, when the number of the updating rounds reaches a preset number, adjusting the similarity threshold and the consistency threshold;
and step S502, clustering each component unit again according to the adjusted similarity threshold and consistency threshold.
Specifically, when the number of update rounds of the agent reaches the preset number of rounds, the parameter indicating that the agent has been updated many times but the output packetization policy still does not meet the management requirement, and it may be that there is an error in the input data, that is, the clustering result is inaccurate. For example, a similarity threshold setting that is too low or a consistency threshold setting that is too low, results in the resulting cluster being too large. Therefore, in order to avoid endless cyclic updating and waste of calculation cost, when the number of updating rounds of the agent reaches the preset number of rounds, the similarity threshold and the consistency threshold are adjusted, each component unit is clustered again after adjustment, and then each cluster generated again is input into the agent again.
