Description

Technical Field

[0001] This application relates to the field of digital management technology for electromechanical engineering, and in particular to a method and system for resource allocation in electromechanical engineering based on spatial coupling degree. Background Technology

[0002] As the construction industry transforms towards digitalization and intelligence, Building Information Modeling (BIM) technology has become a core tool for improving the design and construction management of electromechanical engineering.

[0003] Mechanical and electrical engineering, as the complex nervous system of modern buildings, involves numerous pipelines, interwoven systems, and a compact spatial layout. Traditional resource allocation methods heavily rely on two-dimensional drawings and the personal experience of project engineers, resulting in several inherent shortcomings: During the project planning phase, there is a lack of efficient methods to determine the optimal installation sequence of components and resource plans; during the project execution phase, there is an inability to promptly respond to changes in objective conditions (such as changes in material handling routes or processing areas) and to reflect these changes in resource allocation. These deficiencies lead to high rates of idle tools and equipment, low utilization of human resources, and even failure to meet project deadlines. Summary of the Invention

[0004] This application provides a method, system, electronic device, and storage medium for configuring electromechanical engineering resources based on spatial coupling degree, so as to at least solve the problem of low utilization rate of electromechanical engineering resources in related technologies.

The parameter values ​​of each process parameter are determined based on the process bounding box and process sequence. The construction priority of the components is sorted according to the parameter values ​​and the weights corresponding to each process parameter.

[0007] In some embodiments, determining the parameter values ​​for each process parameter based on the process bounding box and the process sequence includes: When the process enclosure occupies public space, the parameter value of the first process parameter is set to 0; If the process enclosure does not occupy public space, the parameter value of the first process parameter is set to 1.

[0008] In some embodiments, determining the parameter values ​​for each process parameter based on the process bounding box and the process sequence includes: If the first process bounding box is completely inside the second process bounding box, then the first process bounding box and the second process bounding box are considered to have an inclusion relationship. For bounding boxes of processes that have an inclusion relationship, a spatial tree is constructed, and the parameter value of the second process parameter is determined based on the depth of the bounding box of the process in the spatial tree.

[0009] In some embodiments, generating the process bounding box for each BIM component based on the process method and the 3D model of the component includes: Generate the bounding box of the BIM component based on the 3D model; Based on the aforementioned process and the component enclosure, the process space occupied by the BIM component is determined. Based on the continuous operation process and spatial constraints, the space occupied by the process is modified to obtain the process bounding box of each BIM component.

[0010] In some embodiments, the process of correcting the space occupied by the process based on consecutive work steps and spatial constraints to obtain the process bounding box of each BIM component includes: Based on Boolean union operations, the space occupied by consecutive operation steps is merged to obtain the process bounding box; and / or Determine whether the space occupied by the process meets the space constraint conditions. If not, reselect the equipment used in the process, correct the space occupied by the process, and obtain the process enclosure box based on the corrected space occupied by the process.

[0011] In some embodiments, the total resource pool includes the total resource amount per unit time, and the task set includes priority tasks and ordinary tasks; generating a resource competition model based on the total resource pool, the task set, and the construction priority ranking result includes: Determine the resource consumption per unit time for each priority task, and determine the remaining resources per unit time based on the resource consumption per unit time and the total resource amount per unit time. Based on the remaining resources per unit time and the construction priority ranking results of each of the ordinary tasks, a resource competition model is constructed.

[0012] In some embodiments, the weights of the first process parameter, the second process parameter, the third process parameter, the fourth process parameter, and the fifth process parameter decrease sequentially.

[0013] Secondly, embodiments of this application provide an electromechanical engineering resource allocation system based on spatial coupling degree, the system comprising: The bounding box generation module is used to determine the process and construction method of each BIM component based on the pre-built mapping relationship between WBS tasks and BIM components, and generate the process bounding box of each BIM component according to the process and construction method and the three-dimensional model of the component.

[0015] Fourthly, embodiments of this application provide a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the electromechanical engineering resource allocation method based on spatial coupling degree as described in the first aspect above.

[0016] Compared with related technologies, the electromechanical engineering resource allocation method based on spatial coupling degree provided in this application embodiment achieves precise resource allocation through a resource competition model, avoids the idleness and accumulation of resources on the construction site, and solves the problem of low utilization rate of electromechanical engineering resources.

[0017] Based on the construction process of BIM components, a three-dimensional "process bounding box" representing the space required for construction is automatically generated for each component. This not only considers the component itself, but also the space required for dynamic construction, which can detect and avoid potential spatial conflicts and work surface interference during construction in advance, ensuring the reliability and feasibility of the schedule.

[0018] By quantifying spatial relationships and process sequences into calculable process parameters and combining them with weights, the construction priority ranking is automated, avoiding biases and errors in subjective judgment and improving the accuracy of decision-making.

[0024] This embodiment provides a method for configuring electromechanical engineering resources based on spatial coupling degree. Figure 1 This is a flowchart of a method for allocating electromechanical engineering resources based on spatial coupling degree according to an embodiment of this application, such as... Figure 1As shown, the process includes the following steps: Step S101: Based on the pre-built mapping relationship between WBS tasks and BIM components, determine the process and construction method of each BIM component, and generate the process bounding box of each BIM component according to the process and construction method and the three-dimensional model of the component.

[0025] By using the BIM model, a BIM space corresponding to the physical space at a 1:1 scale is established. Based on the sub-item plan, a schedule plan with space and room as the smallest granularity is generated.

[0026] Specifically, a mapping network between WBS tasks and BIM components is constructed. By identifying BIM components within the bounding box of a BIM room, the room is associated with the WBS to form a planning space column. Using the room as the dimension, all components within the same BIM room are extracted to generate room tasks.

[0027] Within the entire project area, a three-dimensional space is divided using a BIM model, a spatial topology network is established, and a standardized spatial attribute naming system is created.

[0028] Existing physical boundaries in the project are selected, and spatial divisions are defined in the BIM model: vertical components (such as load-bearing walls and permanent guardrails) form vertical spatial boundaries, horizontal components (such as floor slabs) define planar partitions, and dynamic components (such as movable partitions and temporary fences) define flexible spatial edges. The divided rooms are categorized into public spaces (handling, processing, and storage) and construction spaces; a space can be either a public space or a construction space. Table 1 is a rule table for naming based on spatial attributes according to an embodiment of this application.

[0029] Table 1

[0030] By identifying spatial edge relationships in BIM components, topological relationships between spaces are automatically established. For example, if spaces A and B on the same floor are connected by a path (horizontally connected by doors and / or other spaces), it is determined to be a first relationship (ADJ); if spaces C and D on different floors are connected by a path (vertically connected by elevators, etc.), it is determined to be a second relationship (BH). Table 2 is a basic table of spatial attributes according to an embodiment of this application.

[0031] Table 2

[0032] Establish spatial topology relationships and form topology relationship coding rules: Space ID_Topology Type_Associated Space ID (e.g., B201_ADJ_B205 indicates that spaces B201 and B205 are on the same level and connected by a path; A101_ADJ_A102 and A101_ADJ_A103 indicate that space A101 is a common transport space for A102 and A103). Table 3 is a topology relationship-spatial attribute coding table according to an embodiment of this application. As shown in Table 3, A101 belongs to the common transport space and is used as the transport space for A102, A103, and D101.

[0033] Table 3

[0034] In some embodiments, step S101, which generates the process bounding box for each BIM component based on the process method and the 3D model of the component, includes: Step S1011: Generate the component bounding box of the BIM component based on the 3D model.

[0035] Step S1012: Based on the process method and component bounding box, determine the process space occupied by the BIM component.

[0036] Step S1013: Based on the continuous operation process and spatial constraints, the space occupied by the process is corrected to obtain the process bounding box of each BIM component.

[0037] Using a space or room as the granularity for resource planning, BIM components and their key attributes are extracted from the space. These key attributes include the component's elevation, the XYZ coordinates of its smallest coordinate system bounding box (AABB), and the WBS task it belongs to. This process involves selecting construction methods to determine the work sequence, and simultaneously defining the physical bounding box of the BIM component.

[0038] Specifically, based on the 3D model of the BIM component, attributes (such as coordinates and dimensions) are extracted, physical entity space is established, and axis-aligned bounding boxes (AABBs) and directed bounding boxes (OBBs) of the component are generated. By calculating the covariance matrix of the vertices of the component's triangular mesh, the eigenvectors are the principal axes of the OBBs. Among them, the axis-aligned bounding box (AABB) is used to determine the space occupied by the process, and the directed bounding box (OBB) is used for subsequent component spatial coupling analysis.

[0039] By extracting the attributes of BIM components and combining them with WBS tasks and BIM mapping, as well as the mapping between WBS and industry quotas, the construction process of the component is determined, and the resources involved (such as machinery, tools, etc.) are determined based on the construction process used for the component. Table 4 is a WBS task-BIM component-quota three-element mapping table according to an embodiment of this application.

[0040] Table 4

[0041] Based on the selected resource configuration type, the physical enclosure of the component is expanded to form the process space. It should be noted that in this embodiment, space is established for different processes such as manufacturing, handling, installation, and testing.

[0042] Define the basic process space required for each process and form a spatial bounding box. The spatial occupancy of each component is represented by its axis-aligned (AABB) bounding box, using the coordinates of two diagonal points p. min =(x min ,y min ,z min ) and p max =(x max ,y max ,z max This definition precisely describes the geometric boundary. It ensures the bounding box is aligned with the global coordinate system, facilitating spatial computation. Where p... min p max Let x be the diagonal coordinate point. min ,y min , z min Let x be the XYZ coordinates of the nearest point. max ,y max , z max The coordinates of the far point are XYZ axes.

[0043] Different process tools (such as lifts, cranes, ladders, mobile scaffolding, etc.) will result in differences in the space occupied by component processes. Adjusting the tool dimensions requires expanding the boundary of the enclosure box.

[0044] x' min To account for the tool's footprint size, the x-axis coordinate of the nearest point of the process's bounding box is x'. max To account for the tool's footprint size, the x-axis coordinate of the far point of the process's bounding box is calculated. , This represents the difference in the increased footprint of the process along the x-axis. The same principle applies to the y-axis and z-axis directions.

[0045] Table 5 is a tooling space standard table according to an embodiment of this application. As shown in Table 5, a is the basic space length for completing the process without the aid of a spacer; b is the space width for completing the process without the aid of a spacer; h is the space height for completing the process without the aid of a spacer; A is the physical space length of the spacer; B is the physical space width of the spacer; and H is the physical space height of the spacer.

[0046] Table 5

[0047] The space B occupied by process P of component i i (P) represents the formula as follows:

[0048] In some embodiments, step S1013 includes: Step S201: Based on Boolean union operation, merge the process space occupied by consecutive operation processes to obtain the process bounding box.

[0049] For continuous operations, the bounding boxes of multiple processes need to be merged, and the largest range B after merging is taken. process Let B be the bounding box of adjacent processes in a continuous operation. i 、B j Its space occupies Boolean union operations:

[0050] Step S202: Determine whether the space occupied by the process meets the space constraint conditions. If not, reselect the tools used in the process, correct the space occupied by the process, and obtain the process bounding box based on the corrected space occupied by the process.

[0051] Provided that the specifications are met, the impact of using spacer equipment is constrained by spatial attributes such as the general space where the BIM component is located, the physical space of the BIM component, and the public space. For example, the impact of using prefabricated mobile scaffolding is constrained by the floor height T. i (This layer), T +1 (Upper layer), Ta (installation height), TTRANSPORT_[spatial code] (reads the common transport space height of the space related to the topological relationship ID of the room where the component is located), the directional boundary of the bounding box must satisfy:

[0052] Where M(T) is the sum of the heights of all relevant public spaces. If the limits are exceeded, it is necessary to select a different model of the space-reserving device, or consider not using the space-reserving device at all.

[0053] Continue to refer to Figure 1 After obtaining the process enclosure box, step S102 is executed.

[0054] Step S102: Determine the parameter values ​​of each process parameter based on the process bounding box and process sequence. Sort the construction priority of the components according to the parameter values ​​and the weights corresponding to each process parameter. The process parameters include spatial relationship parameters and sequence relationship parameters.

[0055] The component installation priority is calculated based on whether it occupies the public space SP, the relationship between process bounding boxes (whether they contain each other, number of collisions, etc.), the relationship between process bounding boxes and component physical bounding boxes, and the number of subsequent processes.

[0056] In some embodiments, the spatial relationship parameters include a first process parameter, a second process parameter, a third process parameter, and a fourth process parameter, and the sequential relationship parameters include a fifth process parameter; The first process parameter is used to characterize whether the process enclosure occupies public space.

[0057] The first process parameter characterizes the spatial relationship between the space occupied by the process and the common space. Processes that do not occupy common space have higher priority, while processes that occupy common space have lower priority. The first process parameter has the highest weight.

[0058] The second process parameter is used to characterize the inclusion relationship between the bounding boxes of each process.

[0059] The third process parameter is used to characterize the coupling degree between the completed component and the enclosing box of other processes.

[0060] The third process parameter is the number of times a component collides with other process enclosures after a certain component is completed.

[0061] The fourth process parameter is used to characterize the intersection relationship between the bounding boxes of each process.

[0062] The fifth process parameter is used to characterize the number of subsequent processes for the current process.

[0063] The weights of the parameters for the first, second, third, fourth, and fifth processes decrease sequentially.

[0064] Within the room, assuming there are n components, the sorted sequence L is obtained by arranging them in descending order by key(k) (larger values ​​first). Using sorting operators: L=sort_desc(key(k j )) , j∈{1,2,...,n} Where the sequence position index j∈{1,2,...,n} satisfies: if key(k j The larger the value of k, the better the component k. j The earlier a position appears, the higher its priority, and the smaller j is (i.e., the earlier it appears in the sort). The sequence L = (k1, k2, ..., kn) satisfies: key(k1)≥key(k2)≥...≥key(k n ) Based on the weighted sum model, the standardized attributes are combined with weights to obtain the key value key(k): key(k) =ω1f1'(k)+ω2f2'(k)+ω3f3'(k)+ω4f4'(k)+ω5f5'(k) Wherein, f1'(k) is the value of the first process parameter, f2'(k) is the value of the second process parameter, f3'(k) is the value of the third process parameter, f4'(k) is the value of the fourth process parameter, and f5'(k) is the value of the fifth process parameter; ω i These are the weights corresponding to each parameter. Weight ω i The comparison is performed such that ω1 > ω2 > ω3 > ω4 > ω5, ensuring that high-priority attributes (such as whether they touch a common space) dominate the comparison. Weights are set to an exponentially decaying form to numerically guarantee the priority order. ω i =10 i+a(5-i) i=1,2,3,4,5 Where a is a non-zero natural number. When a is 2, ω1 is 10. 9 ω2 is 10 7 ω3 is 10 5 ω4 is 10 3 ω5 is 10 1 .

[0065] The calculation formulas for each process parameter are as follows: f i '(k) =f i (k) / R i i=1,2,3,4,5 Among them, R i It is the theoretical maximum value or upper bound of parameter i, to ensure f i '(k)∈[0,1]. Optionally, f i (k) Uses the rounding standard, retaining a maximum of one decimal place.

[0066] In some embodiments, step S102 includes: Step S1021: When the process enclosure occupies the common space, set the parameter value of the first process parameter to 0.

[0067] Step S1022: Without occupying public space, set the parameter value of the first process parameter to 1.

[0068] The parameter values ​​for the first process are calculated as follows:

[0069] If the process enclosure occupies public space, then If the process enclosure does not occupy public space, then .

[0070] In some embodiments, step S102 further includes: Step S1023: If the first process bounding box is completely inside the second process bounding box, then it is considered that the first process bounding box and the second process bounding box have an inclusion relationship.

[0071] Step S1024: For bounding boxes of processes with containment relationships, construct a spatial tree and determine the parameter values ​​of the second process parameters based on the depth of the bounding boxes in the spatial tree.

[0072] The parameter values ​​for the second process are calculated as follows: f2(k) =d max -d(k) Where, d max Let d(k) be the maximum depth of the spatial tree, d(k) be the depth of the bounding box of the current process, the root node depth be 0, and the value range be [0, d]. max The deeper the bounding box of a process is in the spatial tree, the later it is sorted.

[0073] The third process parameter characterizes the spatial relationship between the completed component and the bounding box of other component processes, that is, the coupling degree ranking of the space occupied by other component processes due to the completion of a certain component (optionally, the coupling degree is represented by the number of collisions). The higher the coupling degree, the later the process is.

[0074] The parameter values ​​for the third process are calculated as follows: f3(k) = C max -C(k) Among them, C max C(k) represents the maximum number of collisions, and C(k) represents the number of collisions with other process bounding boxes caused by the completion of the current component. It should be noted that after the component is completed, its coupling degree (number of collisions) with other process bounding boxes is analyzed through its directed bounding box (OBB).

[0075] The fourth process parameter characterizes the number of intersection relationships between process bounding boxes, that is, the coupling degree ranking between process bounding boxes. The higher the coupling degree, the later the process is.

[0076] The formulas for calculating the parameter values ​​of the fourth process are as follows: f4(k) = I max -I(k) Among them, I max I(k) represents the maximum number of intersections, and I(k) represents the number of intersections between the current process bounding box and other process bounding boxes.

[0077] The fifth process parameter indicates the number of subsequent processes corresponding to this process. Processes are prioritized based on their time constraints, with longer-time processes ranked higher.

[0078] The formulas for calculating the parameter values ​​of the fifth process are as follows: f5(k) = S(k) Where S(k) represents the number of subsequent processes corresponding to the current process.

[0079] In this embodiment, the priority ranking can be modified according to changes in the actual project situation. For example, when the components of the rooms related to the public space T are installed, or when other alternative public spaces appear, the public space SP is eliminated, triggering the space occupancy coupling degree ranking engine for re-ranking. It should be noted that when the construction space components corresponding to the public space T are installed, the public space T is eliminated, and the spatial constraint judgment between the process bounding box of component k and the public space T changes to a non-contact state.

[0080] For BIM components within a spatial area, the quantity of work is calculated according to the quota standard. Based on the quota man-day consumption, the completion time for BIM components is calculated. A three-element mapping schedule calculation table is established based on "BIM component-WBS-space" to calculate the quota schedule for WBS tasks within the room bounding box. Table 6 is a BIM component-WBS-space three-element mapping table according to an embodiment of this application.

[0081] Table 6

[0082] Using the above methods, based on the start time of the collection project and considering the sequential construction requirements between rooms, the priority order of BIM component processes in all spaces of the target project, sorted by the spatial occupancy coupling degree sorting engine, is calculated.

[0083] Continue to refer to Figure 1 After prioritizing the construction work, proceed to step S103.

[0084] Step S103: Construct a resource pool and task set for the construction period. Based on the resource pool, task set, and construction priority ranking results, generate a resource competition model.

[0085] Establish a resource pool for each cycle (e.g., one day or one week), including but not limited to various types of labor, key tools, equipment, and materials. Set a resource cap for each cycle, for example, team A has a total of 120 man-days of manpower available for allocation today. Each cycle (day / week) involves resource competition among already sorted components, with components having higher sorting priority receiving resource allocation first. If there are changes to the common space in each cycle (common space becomes a related construction area, disappears, is transferred, etc.), the spatial coupling degree sorting and resource competition are re-performed.

[0086] The resource pool vector R is:

[0087] Where j is the resource type, J is the set of resource types, k is time, and r is... jk Let $j$ be the maximum total amount of resource $j$ on day $k$.

[0088] Extract the "WBS-BIM component-space" ternary mapping relationship and establish the task set for day k. k :

[0089] u i Let N represent the i-th task, and N be the total number of tasks.

[0090] In some embodiments, the total resource pool includes a daily total resource pool, and the task set includes priority tasks and regular tasks; step S103 specifically includes: Step S1031: Determine the resource consumption per unit time for each period of the priority task, and determine the remaining resources per unit time based on the resource consumption per unit time and the total resource amount per unit time.

[0091] Step S1032: Based on the remaining resources per unit time and the construction priority ranking results of each ordinary task, construct a resource competition model.

[0092] For example, if the unit of time is day and hour, u ij This represents the daily resource requirement of task i, ㄒ priority For task set The priority task set (tasks that objectively must be carried out first), ㄒ tes This refers to the ordinary task set within the task set ㄒ.

[0093] Consider the resource consumption of priority tasks: r jk ’ =r jk -u pj Among them, u pj The total amount of resources j used by the daily priority task p, r jk ’ Let J be the total remaining resources of resource j on day k.

[0094] Step S104: Based on the resource competition model and the resource status of the total resource pool, obtain the construction strategy and the corresponding resource allocation strategy.

[0095] Based on the resource competition model and the results ranked according to construction priority, resources are first allocated to priority tasks, and then the remaining resources are allocated to ordinary tasks. Specifically, based on the calculated workload within the spatial scope, the standard quota consumption of each process, and the schedule requirements, the upper limit of spatial constraints on resource quantity is considered to arrange the resources.

[0096] It should be noted that the total resource pool can be adjusted according to the actual situation. For example, if the total resource pool for a certain resource is not used up for several consecutive days, the total resource pool can be reduced to save costs.

[0097] In practical engineering projects, to meet tight deadlines, the resource pool limit can be temporarily increased. Furthermore, at the end of each cycle or when the common space SP is eliminated, the space occupancy coupling degree ranking engine and the resource contention model need to be re-executed. Figure 2 This is a flowchart illustrating the operation of a resource contention model according to an embodiment of this application.

[0098] Through the above steps, based on the construction process of BIM components, a three-dimensional "process bounding box" representing the space required for construction is automatically generated for each component. This not only considers the component itself, but also the space required for dynamic construction, which can detect and avoid potential spatial conflicts and work surface interference during construction in advance, ensuring the reliability and feasibility of the schedule.

[0099] By quantifying spatial relationships and process sequences into calculable process parameters and combining them with weights, the construction priority ranking is automated, avoiding biases and errors in subjective judgment and improving the accuracy of decision-making.
