Description

Technical Field

[0001] This application relates to the field of construction resource scheduling technology, and more specifically, to a joint scheduling command and management system and method for engineering construction. Background Technology

[0002] In the field of engineering construction, especially in scenarios where multiple projects are carried out in parallel, construction resources are characterized by their complexity and dynamic changes in demand. They often face challenges such as cross-project resource competition, sudden failures of in-use resources, and resource gaps in work process coordination. This results in some projects having resources idle for extended periods, while others halt construction due to resource shortages, directly leading to schedule delays and cost overruns. Construction resource scheduling, as a core means of addressing these challenges, achieves precise allocation of resources across different projects and work processes by comprehensively planning initial resource allocation, collecting real-time resource operation status and project demand information, dynamically adjusting resource flow paths, and combining project priorities. This ensures seamless flow of in-use resources during task transitions and activates backup resources through hierarchical scheduling at the project, regional, and headquarters levels, while simultaneously updating resource location, function, and other statuses to ensure information transparency. It provides crucial technical support for the joint scheduling and command management of engineering construction.

[0003] However, existing joint dispatch and command management systems for engineering construction generally suffer from several shortcomings. These include a lack of multi-project resource constraint identification systems, non-real-time collection of cross-project dispatch situation information, unscientific setting of flexible planning deviations, difficulty in accurately determining coordination and allocation trends, insufficient acquisition and allocation mechanisms for cross-domain congestion descriptions, weak ability to generate transfer decision paths and distribution trajectories, lack of cascaded scheduling of backup resources, and lagging equipment status updates. These deficiencies result in a lack of clear benchmarks for initial multi-project resource configuration, a lack of effective data support for real-time dynamic allocation, resource mismatch in construction task coordination, disordered handling of cross-domain resource conflicts, difficulty in efficiently activating backup resources, and asymmetric equipment status information. Consequently, resource idleness and shortages coexist, the risk of project delays increases, cross-domain resource scheduling conflicts frequently occur, construction costs exceed expectations, and the risk of construction interruptions increases due to delayed backup resource response. This makes it difficult to achieve collaborative optimization and joint dispatch and command of multi-project resources, leading to low overall construction efficiency and management levels. Therefore, how to identify constraints on multi-project construction resources throughout the entire process in multi-project parallel construction scenarios to improve the synergy of joint dispatch and command management for multi-project construction is a problem facing the industry. Summary of the Invention

[0004] This application provides a joint scheduling and command management system and method for engineering construction, which can identify the constraints of construction resources of multiple projects throughout the entire process in the scenario of parallel construction of multiple projects, so as to improve the synergy of joint scheduling and command management of multiple construction projects.

[0005] In a first aspect, this application provides a joint dispatching and command management method for engineering construction, the management method comprising the following steps:

[0006] Establish a constraint identification system for multi-project construction resources and collect real-time information on the scheduling status of cross-project construction resources;

[0007] Based on the initial configuration labels of multiple project resources in the static adjustment cycle of construction strategy during engineering construction, the elastic planning deviation of construction resources in cross-project construction is set, and the connection and allocation trend of multiple project resources when construction tasks are balanced is determined by the elastic planning deviation and the scheduling status information.

[0008] The cross-domain congestion description of multiple project resources during dynamic adjustment of construction strategy is obtained, the cross-domain congestion description is ranked and dominated, and the transfer decision path of multiple project resources during joint adjustment of construction plan is generated. Then, the collection and distribution flow trajectory of construction resources in use during cross-project construction is determined by the transfer decision path.

[0009] Based on the aforementioned connection and allocation trend and the aforementioned distribution and transfer trajectory, the standby construction resources across projects in the engineering construction are cascaded and scheduled, and the status of construction equipment is updated synchronously.

[0010] In this embodiment, the scheduling status information refers to the real-time resource status, project requirements, and scheduling progress information during cross-project construction.

[0011] In this embodiment, setting the elastic planning deviation of construction resources in cross-project construction based on the initial configuration labels of multi-project resources during the static adjustment cycle of the construction strategy specifically includes:

[0012] Determine the initial configuration labels of various resources during the static adjustment period in multi-project construction;

[0013] The dynamic planning attributes of construction resources in cross-project collaboration are determined based on the initial configuration labels.

[0014] Based on the dynamic programming attributes, the resource allocation status in the construction process of multiple projects is identified, and the elastic planning deviation of construction resources in cross-project construction is obtained.

[0015] In this embodiment, the elastic planning deviation refers to the difference index between the actual resource configuration state and the initial configuration label.

[0016] In this embodiment, the connection and allocation trend refers to the optimal direction, time, and path for the transfer of construction resources from idle projects to projects in demand, ensuring a balanced and coordinated planning result.

[0017] In this embodiment, obtaining the cross-domain congestion description of multiple project resources during dynamic adjustment of construction strategies specifically includes:

[0018] The status assessment characteristics of cross-domain construction resources are constructed by using multi-project resource scheduling interfaces and real-time construction topology relationships;

[0019] Based on the aforementioned status assessment characteristics, cross-domain coordination identifiers for multiple project resources during dynamic adjustments of construction strategies in engineering construction are determined.

[0020] The cross-domain coordination identifier is used to determine the description of cross-domain congestion of multiple project resources during dynamic adjustment of construction strategies in engineering construction.

[0021] In this embodiment, the cross-domain congestion description refers to information that records in detail the specific conflict scenarios that occur during the dynamic adjustment of cross-domain resources.

[0022] In this embodiment, determining the allocation and transfer trajectory of in-use construction resources in cross-project construction based on the transfer decision path specifically includes:

[0023] Extract homomorphic allocation information during cross-project construction resource scheduling operations from the aforementioned transfer decision path;

[0024] The homomorphic allocation information is used to determine the flow guidance sequence in the dynamic flow process of in-use construction resources;

[0025] The circulation guidance sequence determines the collection, allocation, and circulation trajectory of construction resources in use during cross-project construction.

[0026] In this embodiment, the cascading scheduling of standby construction resources across projects during engineering construction, based on the connection and allocation trend and the collection and distribution flow trajectory, and the synchronous updating of construction equipment status, specifically includes:

[0027] The dynamic coordination window for scheduling cross-project standby construction resources is determined based on the aforementioned connection and allocation trend and the aforementioned collection and distribution flow trajectory.

[0028] The dynamic collaborative window is matched with a preset resource capacity threshold to generate a cascading scheduling instruction set for backup resources;

[0029] The cascaded scheduling instruction set triggers real-time allocation of backup construction resources and synchronously updates the construction equipment status database.

[0030] Secondly, this application provides a joint dispatch and command management system for engineering construction, used to execute a joint dispatch and command management method for engineering construction, the management system comprising:

[0031] The information acquisition module is used to establish a constraint identification system for multi-project construction resources and to collect real-time information on the scheduling status of cross-project construction resources.

[0032] The resource allocation module is used to set the elastic planning deviation of construction resources in cross-project construction based on the initial configuration tags of multi-project resources in the static adjustment cycle of construction strategy during engineering construction, and to determine the connection and allocation trend of multi-project resources when construction tasks are balanced and connected through the elastic planning deviation and the scheduling status information.

[0033] The dominance and sorting module is used to obtain cross-domain congestion descriptions of multi-project resources during dynamic adjustment of construction strategies in engineering construction, perform dominance and sorting on the cross-domain congestion descriptions, generate transfer decision paths for multi-project resources during joint adjustment of construction plans, and then determine the collection and distribution trajectory of construction resources in use during cross-project construction based on the transfer decision paths.

[0034] The cascade scheduling module is used to perform cascade scheduling of standby construction resources across projects in the engineering construction based on the connection and allocation trend and the collection and distribution flow trajectory, and to update the status of construction equipment synchronously.

[0035] The technical solutions provided by the embodiments disclosed in this application have the following beneficial effects:

[0036] Establish a constraint identification system for multi-project construction resources and collect real-time information on the scheduling status of resources in cross-project construction; set elastic planning deviations for construction resources in cross-project construction based on the initial configuration labels of multi-project resources in the static adjustment cycle of construction strategies, and determine the connection and allocation trend of multi-project resources when construction tasks are balanced through the elastic planning deviations and the scheduling status information; obtain cross-domain congestion descriptions of multi-project resources in the dynamic adjustment of construction strategies, sort the cross-domain congestion descriptions by dominance, generate transfer decision paths for multi-project resources when construction plans are jointly adjusted, and then determine the collection and distribution trajectory of in-use construction resources in cross-project construction based on the transfer decision paths; perform cascade scheduling of standby construction resources across projects in the project construction based on the connection and allocation trends and the collection and distribution trajectory, and update the status of construction equipment synchronously.

[0037] Therefore, this application demonstrates that it can improve the efficiency of joint scheduling of resources across multiple projects, especially when cross-domain conflicts are difficult to resolve. Specifically, by establishing a constraint identification system for multi-project construction resources and collecting real-time scheduling status information, it clarifies constraints such as resource quantity and time, and obtains dynamic data on equipment operation and manpower shortages. This addresses the shortcomings of existing initial configurations lacking benchmarks and real-time status information, providing accurate data support for subsequent allocation. Furthermore, by setting flexible planning deviations through initial configuration labels in the static adjustment cycle of construction strategies, and combining this with scheduling status information to determine the trend of coordinated allocation, it quantifies the difference between actual and planned resources, clarifies the direction of resource flow, and compensates for the lack of data in existing deviation calculations and allocation methods. To address the issue of ambiguous trends, this approach ensures a balanced and seamless transition between construction tasks. By acquiring cross-domain congestion descriptions during dynamic adjustments to construction strategies, a transfer decision path is generated through dominance sorting, and the distribution flow trajectory is determined. This clearly presents conflict scenarios, clarifies processing priorities and resource flow details, and resolves existing issues of ambiguous conflict identification and disordered decision-making, reducing the risk of cross-domain scheduling conflicts. By connecting allocation trends and distribution flow trajectories, cascaded scheduling of backup resources is performed, and equipment status is updated synchronously. Lower-level resources are prioritized, ensuring real-time and accurate equipment information. This compensates for the existing shortcomings of delayed backup response and asymmetrical status, ensuring construction continuity and ultimately achieving multi-project resource collaborative optimization and improved joint scheduling and command capabilities.

[0038] In summary, the technical solution adopted in this application can identify the constraints of construction resources for multiple projects throughout the entire process in the scenario of parallel construction of multiple projects, so as to improve the synergy of joint scheduling, command and management of construction of multiple projects.

[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] This application provides a method for joint scheduling and command management of engineering construction. Its core is to establish a constraint identification system for multi-project construction resources and collect real-time scheduling status information of resources across projects. Based on the initial configuration labels of multi-project resources during the static adjustment cycle of construction strategies, the method sets elastic planning deviations for construction resources across projects. The elastic planning deviations and the scheduling status information are used to determine the connection and allocation trends of multi-project resources when construction tasks are balanced. The method obtains cross-domain congestion descriptions of multi-project resources during dynamic adjustments of construction strategies, ranks these descriptions to generate transfer decision paths for multi-project resources during joint adjustments of construction plans, and then uses these transfer decision paths to determine the aggregation and distribution trajectory of in-use construction resources across projects. Based on the connection and allocation trends and the aggregation and distribution trajectory, the method performs cascade scheduling of standby construction resources across projects and synchronously updates the status of construction equipment.

[0046] Example 1: To better understand the above technical solution, the following will provide a detailed description of the technical solution in conjunction with the accompanying drawings and specific implementation methods. (Refer to...) Figure 1 As shown in the figure, this is an exemplary flowchart of a joint scheduling and command management method for engineering construction according to this embodiment of the present application. The management method includes the following steps:

[0047] In step S1, a constraint identification system for multi-project construction resources is established, and the scheduling status information of cross-project construction resources is collected in real time.

[0048] In practical implementation, the resources for multiple projects are categorized into six types: equipment, manpower, materials, time, space, and priority. Constraints are defined for each category: total equipment quantity, maximum operating time per unit, and remaining lifespan (e.g., 3 tower cranes, each operating for 12 hours per cycle); manpower statistics for the number of certified workers in each trade (e.g., 5 certified welders); time markers for key process windows (e.g., foundation construction for Project A, days 1-15); space records site and equipment size limitations (e.g., Project B only allows small excavators); and priority is clearly defined, prioritizing projects that prioritize "opening up." A "Project-Resource Constraint Association Table" is created using Primavera software to input information, forming a visual list. All information in this visual list serves as the resource scheduling status information for cross-project construction. In other embodiments, resource scheduling status information for cross-project construction can also be collected through other methods; this is not limited here.

[0049] It should be noted that, in this application, the constraint identification system for multi-project construction resources clearly defines the quantity, time, and space limitations of resources such as equipment and manpower, and sets boundaries for scheduling to avoid exceeding resource capabilities; the scheduling status information refers to the allocation information of real-time resource status, project needs, and scheduling progress in cross-project construction.

[0050] In step S2, the elastic planning deviation of construction resources in cross-project construction is set according to the initial configuration labels of multi-project resources in the static adjustment cycle of construction strategy. The connection and allocation trend of multi-project resources in the balanced connection of construction tasks is determined by the elastic planning deviation and the scheduling status information.

[0051] In this embodiment, setting the elastic planning deviation of construction resources in cross-project construction based on the initial configuration labels of multiple project resources in the static adjustment cycle of construction strategy can be achieved through the following steps:

[0052] Determine the initial configuration labels of various resources during the static adjustment period in multi-project construction;

[0053] The dynamic planning attributes of construction resources in cross-project collaboration are determined based on the initial configuration labels.

[0054] Based on the dynamic programming attributes, the resource allocation status in the construction process of multiple projects is identified, and the elastic planning deviation of construction resources in cross-project construction is obtained.

[0055] In practice, the static adjustment cycle for the construction strategy can be set monthly, with configuration initiated on the 1st of each month. Resources are divided into three categories: equipment, manpower, and materials. For equipment, each piece of equipment (e.g., tower crane 01, concrete pump truck 02) is tagged with its resource ID, type, assigned project, planned monthly usage cycle (e.g., January 1st - January 31st), and planned daily usage time (e.g., 8 hours). For manpower, each trade (e.g., welders, electricians) is tagged with its trade, number of certified workers, assigned project, and planned monthly working days (e.g., 22 days). For materials, each batch of materials (e.g., steel bars, cement) is tagged with its material ID, type, assigned project, and planned monthly supply (e.g., 500 tons). These tags are entered into Primavera software to create a "resource-project-tag" relational database. By reading this database, the initial configuration tags for various resources in multiple construction projects under the static adjustment cycle are obtained. Then, initial configuration tags are extracted from Primavera software and analyzed by resource type: For equipment, idle periods are calculated based on the "monthly planned usage cycle," such as a tower crane with a planned usage period from 1.11 to 1.10 and no planned usage from 1.11 to 1.31, marked with the dynamic planning attribute "can be allocated across projects, idle period 1.11-1.31"; for manpower, overlapping project needs are considered, such as a welder assigned to project B but only working 6 hours per day, marked "can support project C, 2 hours per day"; for materials, based on "planned consumption nodes" and shelf life, such as 20 tons of cement remaining with sufficient shelf life, marked "20 tons can be allocated, validity period 1.26-2.10," thus obtaining the dynamic planning attributes of construction resources in cross-project collaboration. Finally, actual data is collected from the resource management system at the end of each month: actual monthly usage time is extracted for equipment; actual on-duty days and daily working hours are recorded for manpower; and actual consumption is recorded for materials. Based on the benchmark in the dynamic planning attributes, the flexible planning deviation is calculated according to "elastic planning deviation = (actual usage / total monthly duration) - (planned usage / total monthly duration)", and is classified and marked as idle (positive) or gap (negative) to form the flexible planning deviation of construction resources in cross-project construction.

[0056] It should be noted that in this application, the static adjustment period of the construction strategy refers to the fixed period for determining the initial allocation of resources in multi-project construction; the initial allocation label refers to the basic allocation information of various resources within the static adjustment period; the dynamic planning attribute refers to the flexible adaptation characteristics of resources in cross-project allocation; and the elastic planning deviation refers to the quantitative indicator of the difference between the actual resource allocation status and the initial allocation label.

[0057] Preferably, in this embodiment, the trend of resource allocation and coordination among multiple projects during the balanced connection of construction tasks is determined by the elastic planning deviation and the scheduling situation information, with reference to... Figure 2As shown in the figure, this is a flowchart illustrating the process of determining the coordination and allocation trend in some embodiments of this application. In this embodiment, determining the coordination and allocation trend can be achieved through the following steps:

[0058] In step S21, the connection deviation index of multi-project resources in the construction task connection process is determined according to the elastic planning deviation;

[0059] In step S22, a balanced connection contribution amount matching the construction stages of multiple projects is generated based on the connection deviation index.

[0060] In step S23, the balanced connection contribution is fused and matched with the scheduling situation information to obtain a dynamic consensus sequence of multi-project resources when construction tasks are balanced and connected.

[0061] In step S24, the dynamic consensus sequence is used to determine the coordination and allocation trend of resources across multiple projects when construction tasks are balanced and coordinated.

[0062] In practice, firstly, the deviation values ​​of resources at task connection nodes (such as the interval between the end of a process in Project A and the start of a process in Project B) are extracted from the flexible planning deviation data, and calculated by resource type: for equipment, the idle time during the connection period is counted, such as tower crane 01 being idle for 3 days from January 12th to January 15th, with a connection deviation index of +3 days; for manpower, the total number of person-days waiting for work during the connection period is counted, such as 2 welders waiting for work from February 1st to February 3rd, with an index of +6 person-days; for materials, the surplus quantity during the connection period is counted, such as 10 tons of steel bars remaining, with an index of +10 tons. All results are used as the connection deviation index for multi-project resources in the process of connecting construction tasks. Next, combining the resource demand intensity of multiple project construction phases (foundation construction, main structure construction, etc.), the contribution amount is calculated by assigning values ​​to the connection deviation index: For equipment, the contribution is calculated as idle time × corresponding phase demand coefficient (this corresponding phase demand coefficient can be set according to expert experience, 1.2 for the foundation phase and 1.0 for the main structure phase). For example, if tower crane 01 is idle for 3 days and is in the foundation phase of project B, the contribution amount is 3 × 1.2 = 3.6. For manpower, the contribution is calculated as idle man-days × daily wage savings. For example, if 6 man-days of welders are idle, saving 500 yuan per day, the contribution amount is 6 × 500 = 3000 yuan. For materials, the contribution is calculated as surplus quantity × current market price. For example, if 10 tons of steel bars are surplus and the market price is 4000 yuan / ton, the contribution amount is 10 × 4000 = 40000 yuan. The contribution amounts are sorted from high to low to obtain the balanced connection contribution amount matching the multiple project construction phases. Then, the real-time project demand, real-time resource location, and transportation feasibility (road accessibility, reachable within 1 hour) are extracted from the scheduling status information. This information is matched with the contribution of balanced coordination: Tower Crane 01 contributes 3.6, its demand time matches its idle period, transportation is feasible, and it is marked as "high matching degree"; if the resource contribution is high but transportation is hindered, it is marked as "low matching degree". A sequence is generated according to "high matching degree → contribution amount sorting", and this sequence is used as the dynamic consensus sequence for the balanced coordination of multi-project resources in construction tasks. Finally, for the first resource in the dynamic consensus sequence (Tower Crane 01 → Project B), the trend is refined: the flow direction is from Project A to Project B; the time window is January 12-15 (matching the demand of Project B and the idle period of the tower crane); the transportation route is Project A → XX Road → Project B (reachable in 1 hour). The coordination details are clarified: the removal inspection of Tower Crane 01 at Project A is completed on January 11, and it arrives at Project B before 8:00 on January 12, and is accepted by the equipment manager of Project B; the refined trend is used as the coordination and allocation trend of multi-project resources in the balanced coordination of construction tasks.

[0063] It should be noted that, in this application, balanced connection of construction tasks refers to the connection status in which resources and schedules are coordinated among multiple construction projects to avoid imbalance and ensure smooth progress of the overall construction; connection deviation index refers to the quantification of the difference between the actual and planned allocation of resources at different construction task connection nodes of multiple projects; balanced connection contribution refers to the measure of the potential contribution of resources to balanced connection of tasks in different construction stages of multiple projects; dynamic consensus sequence refers to the priority ranking sequence of resource allocation in multiple construction tasks; connection allocation trend refers to the optimal direction, time and path of construction resources flowing from idle projects to demanding projects, ensuring the planning results of balanced connection of tasks.

[0064] In step S3, the cross-domain congestion description of multiple project resources during the dynamic adjustment of construction strategy is obtained, the cross-domain congestion description is sorted by dominance, and the transfer decision path of multiple project resources during the joint adjustment of construction plan is generated. Then, the transfer decision path determines the collection and distribution trajectory of construction resources in use during cross-project construction.

[0065] In this embodiment, obtaining the cross-domain congestion description of multiple project resources during dynamic adjustment of construction strategies during engineering construction can be achieved through the following steps:

[0066] The status assessment characteristics of cross-domain construction resources are constructed by using multi-project resource scheduling interfaces and real-time construction topology relationships;

[0067] Based on the aforementioned status assessment characteristics, cross-domain coordination identifiers for multiple project resources during dynamic adjustments of construction strategies in engineering construction are determined.

[0068] The cross-domain coordination identifier is used to determine the description of cross-domain congestion of multiple project resources during dynamic adjustment of construction strategies in engineering construction.

[0069] In practical implementation, firstly, the resource scheduling interfaces of multiple projects are established. Through API connections with the management systems of each project, resource data is collected in real time: for equipment, the real-time location of each piece of equipment (e.g., pump truck 01 at coordinates X1, Y1 in project A) and its operating status (in use / idle); for transportation, the transportation routes and estimated arrival times are obtained. Simultaneously, a real-time construction topology map is constructed using CAD, marking the construction areas, resource transportation channels, and process time windows for each project. Features are extracted from the data: resource spatial density (e.g., 3 tower cranes in area XX), time overlap (e.g., two projects simultaneously require pump trucks at 8:00), and path occupancy rate (e.g., number of transport vehicles on route XX), forming a feature list. This feature list serves as the status assessment feature for cross-domain construction resources. Then, define the labeling and classification rules: resource competition (multiple projects simultaneously requiring the same resource, such as "two projects need pump trucks at 8:00") is labeled "Equipment Competition - Pump Truck"; route conflict (transport route occupancy exceeds 80%, such as "5 transport vehicles on XX Road are loaded") is labeled "Route Congestion - XX Road"; time overlap (work process time windows overlap exceeds 70%) is labeled "Time Conflict - Work Processes A and B". Match the status assessment features with the rules, and automatically assign corresponding labels to features that meet the conditions, such as "Equipment Competition - Pump Truck" and "Route Congestion - XX Road". The results of assigning corresponding labels are used as cross-domain coordination labels for multiple project resources during dynamic adjustments of construction strategies in engineering construction. Finally, cross-domain coordination identifiers from the identifier library are used, and details are supplemented by real-time construction data: For the "Equipment Competition - Pump Truck" identifier, the following are added: involved projects (critical process of Project A, non-critical process of Project B), required time (8:00-12:00), and current equipment location; for the "Route Congestion - XX Road" identifier, the following are added: involved transportation tasks (steel reinforcement of Project C, cement of Project D), congestion period (7:30-9:00), and estimated delay duration. The integrated result of this information serves as a description of cross-domain congestion when multiple project resources are dynamically adjusted during construction strategies.

[0070] It should be noted that, in this application, dynamic adjustment of construction strategy refers to the adjustment of strategy based on real-time resources and schedule during multi-project construction to adapt to changes and ensure smooth construction; status assessment characteristics refer to the set of characteristics of real-time distribution, interaction and conflict potential of cross-domain construction resources; cross-domain coordination identifiers refer to the classification labels that mark the coordination needs and conflict types of cross-domain resources in dynamic adjustment; and cross-domain congestion descriptions refer to the detailed information of specific conflict scenarios that occur in cross-domain resources during dynamic adjustment.

[0071] Preferably, in this embodiment, the cross-domain congestion description is ranked to generate a transfer decision path for resources from multiple projects during joint adjustments to the construction plan, with reference to... Figure 3As shown in the figure, this is a flowchart illustrating the process of determining the transfer decision path in some embodiments of this application. In this embodiment, determining the transfer decision path can be achieved through the following steps:

[0072] In step S31, the allocation and ranking rules for resources across multiple projects during joint adjustments to the construction plan are determined;

[0073] In step S32, the cross-domain congestion description is subjected to multi-objective clustering according to the dominance ranking rule to generate an initial decision set;

[0074] In step S33, a joint decision vector for resource transfer requirements at each construction stage is determined based on the initial decision set;

[0075] In step S34, the transfer decision path for multi-project resources during joint adjustment of the construction plan is determined based on all joint decision vectors.

[0076] In practical implementation, firstly, rules are set from three dimensions: project, process, and loss. For the project priority dimension, "guaranteeing opening" projects receive 3 points, key projects receive 2 points, and ordinary projects receive 1 point. For the process importance dimension, critical path processes receive 3 points, secondary critical path processes receive 2 points, and non-critical path processes receive 1 point. For the delay loss dimension, a delay of 1 day with a loss ≥ 200,000 yuan receives 3 points, 100,000-200,000 yuan receives 2 points, and < 100,000 yuan receives 1 point. Each cross-domain congestion description involves corresponding scores for the project, process, and loss. The total score = project priority score + process importance score + delay loss score. The projects are ranked from highest to lowest total score. If total scores are the same, priority is given based on the project priority dimension score. This yields the allocation and ranking rules for multiple project resources during joint adjustments to the construction plan. Next, the K-means clustering algorithm can be used, with "dominant ranking score" and "conflict type" as clustering features: first, set the number of clusters (e.g., 3 clusters). The first cluster describes equipment competition with a total score of 8-9 (high priority), the second cluster describes path congestion with a total score of 5-7 (medium priority), and the third cluster describes time conflict with a total score of 1-4 (low priority). Input all cross-domain congestion descriptions into the algorithm, which automatically classifies them according to features and then sorts them by total score within each cluster. Extract the top 3 high-priority descriptions from each cluster, and formulate 2-3 preliminary solutions for each description (e.g., calling backup equipment or adjusting process time for equipment competition), integrating them to form an initial decision set. Then, extract core information from each solution in the initial decision set: resource type (e.g., concrete pump truck), resource requirement (e.g., 1 unit), transfer time window (e.g., 1.10, 8:00-12:00), transfer cost (e.g., calling backup equipment costs 20,000 yuan), and delay avoidance loss (e.g., avoiding delay saves 150,000 yuan). This information is organized into a vector using the format "[Resource type, demand, start time window, end time window, transfer cost, delay avoidance loss]". Each construction phase (e.g., foundation construction, main structure construction) corresponds to a set of vectors, forming a joint decision vector for resource transfer demand in that construction phase. Finally, the "net benefit" (net benefit = delay avoidance loss - transfer cost) of each joint decision vector is calculated, and the solution corresponding to the vector with the highest net benefit is selected first. For example, if a vector has a net benefit of 150,000 - 20,000 = 130,000 yuan, and another vector (adjusting process time, no transfer cost, delay avoidance loss of 120,000 yuan) has a net benefit of 120,000 yuan, the former is selected first. After the plan is finalized, the transfer details are clarified: resources will be transferred from the headquarters' backup warehouse. On January 9th at 18:00, transport team A will depart and arrive at the project in need before 7:00 on January 10th. The handover person will be the project's equipment administrator. The transport route (headquarters → XX Road → project in need) will be marked simultaneously. This planning result will serve as the transfer decision path for resources from multiple projects when the construction plan is jointly adjusted.

[0077] It should be noted that in this application, "dominance ranking" refers to a ranking method that sorts resource conflicts according to their degree of impact, clarifies the priority of handling them, and ensures efficient scheduling; "dominance ranking rule" refers to a rule system that provides judgment criteria for orderly handling of resource conflicts and determining decision-making direction; "initial decision set" refers to a set of preliminary decision schemes generated in the joint adjustment of resources for multiple construction projects; "joint decision vector" refers to key information that quantifies the resource requirements, time windows, and cost losses of each scheme in the initial decision set; and "transfer decision path" refers to selecting the resource transfer scheme with the lowest cost and the least loss based on the joint decision vector.

[0078] In this embodiment, determining the allocation and transfer trajectory of in-use construction resources across projects based on the transfer decision path can be achieved through the following steps:

[0079] Extract homomorphic allocation information during cross-project construction resource scheduling operations from the aforementioned transfer decision path;

[0080] The homomorphic allocation information is used to determine the flow guidance sequence in the dynamic flow process of in-use construction resources;

[0081] The circulation guidance sequence determines the collection, allocation, and circulation trajectory of construction resources in use during cross-project construction.

[0082] In practice, firstly, the scheduling system database storing the transfer decision path is opened, and the resource scheduling entries corresponding to that path are filtered. Core homomorphic allocation information is extracted from the entries: basic resource attributes (e.g., in-use construction resource ID is tower crane 03, resource type is large lifting equipment), scheduling entity information (outgoing project is project A, incoming project is project B), time attributes (planned outgoing time 1.15 9:00, planned incoming time 1.15 11:00), and quantity attributes (scheduled quantity 1 unit). This information is then organized in a fixed format: "Resource ID - Type - Outgoing Project - Incoming Project - Outgoing Time - Incoming Time - Quantity". The resulting information is used as the homomorphic allocation information for cross-project construction resource scheduling operations. Then, using the time attribute in the homomorphic allocation information as the core, and combining it with scheduling logic, the flow nodes are broken down as follows: First, Project A conducts a pre-departure inspection of tower crane 03 (January 15, 8:00-9:00), corresponding to the node "Departure Inspection - Project A - Tower Crane 03 - 8:00-9:00"; Second, tower crane 03 departs from Project A for transportation (January 15, 9:00-10:30), corresponding to the node "In Transit - Project A to Project B - Tower Crane 03 - 9:00-10:30"; Third, tower crane 03 arrives at Project B and is accepted (January 15, 10:30-11:00), corresponding to the node "Arrival Acceptance - Project B - Tower Crane 03 - 10:30-11:00". The nodes are arranged in chronological order, and a flow guidance sequence in the dynamic flow process of in-use construction resources is generated using a Gantt chart tool. Finally, details are added for each node in the flow guidance sequence: For the exit inspection node, the inspection location is specified as the equipment parking area of ​​Project A (coordinates X1=121.3, Y1=30.5), and the inspector is Zhang XX, the equipment administrator of Project A; for the transportation node, a specific route is planned using Baidu Maps (Project A → XX Expressway → XX National Highway → Project B), marking key points along the way (arrival at the XX Expressway entrance before 9:15 AM, 10-minute rest at the XX National Highway service area before 10:00 AM), and the transportation team is Transportation Team One; for the entry acceptance node, the acceptance location is specified as the equipment receiving area of ​​Project B (coordinates X2=121.8, Y2=30.7), the acceptance standard is normal equipment operation without faults, and the handover personnel are Wang XX, the equipment administrator of Project B. All these details are integrated into a distribution and flow trajectory table, thus obtaining the distribution and flow trajectory of construction resources in use across projects.

[0083] It should be noted that, in this application, "in-use construction resources" refers to various construction resources that are being used during the construction phase, directly supporting the current construction process and meeting on-site operational needs; "homogeneous allocation information" refers to the unified attribute information of resource scheduling in the transfer decision path; "flow guidance sequence" refers to sorting out the scheduling nodes in the homogeneous allocation information in chronological order; and "collection and distribution flow trajectory" refers to a complete trajectory that clarifies the specific location, route, and handover requirements of resource flow, providing executable guidance for the actual flow of resources.

[0084] In step S4, the standby construction resources across projects are cascaded and scheduled according to the connection and allocation trend and the collection and distribution flow trajectory, and the status of construction equipment is updated synchronously.

[0085] In this embodiment, the cascading scheduling of standby construction resources across projects during engineering construction, based on the connection and allocation trend and the collection and distribution flow trajectory, and the synchronous updating of construction equipment status, can be achieved through the following steps:

[0086] The dynamic coordination window for scheduling cross-project standby construction resources is determined based on the aforementioned connection and allocation trend and the aforementioned collection and distribution flow trajectory.

[0087] The dynamic collaborative window is matched with a preset resource capacity threshold to generate a cascading scheduling instruction set for backup resources;

[0088] The cascaded scheduling instruction set triggers real-time allocation of backup construction resources and synchronously updates the construction equipment status database.

[0089] In practical implementation, firstly, the time window for project needs is extracted from the coordination and allocation trend, such as Project B requiring one tower crane for supplementary construction from January 20th to 22nd. Secondly, the spatial flow path of in-use resources is extracted from the distribution and circulation trajectory, such as in-use tower cranes transporting resources from Project A to Project C from January 19th to 20th, passing through the area surrounding Project B. Using the time window as the vertical axis and the spatial path as the horizontal axis, the overlapping interval of "January 20th to 22nd, within a 30-kilometer radius of Project B" is marked in the GIS map and Project timeline overlay interface. This interval is the dynamic coordination window in the cross-project backup construction resource scheduling process. Then, preset backup resource capacity thresholds for each level are established: project-level backup tower crane threshold is 1 unit (Project B's own backup reserve), regional-level is 2 units (East China regional backup reserve), and headquarters-level is 3 units (corporate headquarters backup reserve). The dynamic collaborative window demand (1 tower crane) is matched with the project-level threshold. The real-time inventory of the Project B spare crane warehouse is checked. If the inventory is 0 (below the threshold of 1 crane), the regional spare crane warehouse is upgraded to be matched. If the inventory is confirmed to be 2 cranes (above the demand), the result is used as the cascading scheduling instruction set for spare resources. Finally, based on the cascading scheduling instruction set, a dispatch notification is sent to the East China regional spare crane warehouse administrator through the scheduling system, specifying the tower crane ID to be dispatched (Spare 05) and transportation requirements (equipment inspection to be completed before 16:00 on January 19th). After receiving the instruction, the transportation team plans a route according to the distribution flow trajectory (regional spare crane warehouse → XX Expressway → Project B), uploading the location to the system every 2 hours during transportation. When the tower crane arrived at Project B at 7:30 on January 20th and completed the handover, the Project B administrator confirmed the acceptance in the system. The system automatically triggered an update to the equipment status database: the "ownership status" of tower crane 05 was changed from "East China region standby" to "Project B in use", and the "location status" was changed from "regional standby database" to "Project B construction site". Then, SQL statements were used to synchronously update the related data tables of the equipment management system and the project management system. This will not be elaborated here.

[0090] It should be noted that, in this application, "backup construction resources" refers to various construction resources that are not put into real-time use during construction but are used to cope with unforeseen circumstances such as fluctuations in cross-project demand and shortages of existing resources, ensuring the continuous progress of construction; "cascaded scheduling" refers to the gradual allocation of resources according to the project, region, and headquarters levels, prioritizing lower levels and then escalating to higher levels to ensure orderly and efficient resource scheduling; "dynamic collaboration window" refers to the core area that clearly defines the time and space scope of backup resource scheduling, ensuring precise alignment between resource allocation and the flow of existing resources and project needs; "preset resource capacity threshold" refers to the pre-setting of capacity standards for backup resources at each level; and "cascaded scheduling instruction set" refers to the set of instructions that clearly defines the objects, time, and quantity of backup resources to be called at the project, region, and headquarters levels.

[0091] Therefore, this application demonstrates that it can improve the efficiency of joint scheduling of resources across multiple projects, especially when cross-domain conflicts are difficult to resolve. Specifically, by establishing a constraint identification system for multi-project construction resources and collecting real-time scheduling status information, it clarifies constraints such as resource quantity and time, and obtains dynamic data on equipment operation and manpower shortages. This addresses the shortcomings of existing initial configurations lacking benchmarks and real-time status information, providing accurate data support for subsequent allocation. Furthermore, by setting flexible planning deviations through initial configuration labels in the static adjustment cycle of construction strategies, and combining this with scheduling status information to determine the trend of coordinated allocation, it quantifies the difference between actual and planned resources, clarifies the direction of resource flow, and compensates for the lack of data in existing deviation calculations and allocation methods. To address the issue of ambiguous trends, this approach ensures a balanced and seamless transition between construction tasks. By acquiring cross-domain congestion descriptions during dynamic adjustments to construction strategies, a transfer decision path is generated through dominance sorting, and the distribution flow trajectory is determined. This clearly presents conflict scenarios, clarifies processing priorities and resource flow details, and resolves existing issues of ambiguous conflict identification and disordered decision-making, reducing the risk of cross-domain scheduling conflicts. By connecting allocation trends and distribution flow trajectories, cascaded scheduling of backup resources is performed, and equipment status is updated synchronously. Lower-level resources are prioritized, ensuring real-time and accurate equipment information. This compensates for the existing shortcomings of delayed backup response and asymmetrical status, ensuring construction continuity and ultimately achieving multi-project resource collaborative optimization and improved joint scheduling and command capabilities.

[0092] In summary, the technical solution adopted in this application can identify the constraints of construction resources for multiple projects throughout the entire process in the scenario of parallel construction of multiple projects, so as to improve the synergy of joint scheduling, command and management of construction of multiple projects.
