Description

Technical Field

[0001] This invention relates to the field of railway design technology, and in particular to a railway design project operation platform and schedule management method based on multi-level control. Background Technology

[0002] Railway survey and design is a core preliminary stage of railway engineering construction. It is characterized by large project scale, long design cycle, multiple professional involvement, strong sequential coordination and coupling, and high requirements for change control. Technical work sheets and scheduling notices are the core management carriers that clarify the task nodes and coordination requirements of each professional group, and directly determine the project progress efficiency and the quality of design results.

[0003] Current traditional project management models in the industry generally lack a hierarchical control system and standardized management foundation adapted to the unique management structure of railway design. Existing management models mostly adopt single-level permission settings, which cannot adapt to the industry-standard three-level management structure of institute level, overall project, and specialized line. The boundaries of authority and responsibility at each level are blurred, and the overall project manager's ability to control the entire discipline is severely insufficient. At the same time, there are no unified standards for task naming, professional division, and management templates across different projects and stages, resulting in chaotic management of basic project information, difficulty in implementing management standards, and extreme difficulty in cross-project data statistics and experience reuse.

[0004] Secondly, the interdisciplinary collaboration process lacks a closed loop, resulting in a severe deficiency in the ability to control schedule risks. Traditionally, the exchange of documents between different disciplines relies heavily on offline file transfers and verbal confirmations, lacking standardized submission processes, confirmation mechanisms, and tiered change control rules. This easily leads to problems such as inconsistent document versions, interdisciplinary buck-passing, and design rework. Task milestone reminders rely on manual notifications, lacking differentiated tiered early warning mechanisms. Consequently, the risk of project delays cannot be identified and addressed in advance, and schedule control lags significantly behind the actual project execution.

[0005] Meanwhile, the existing model fails to effectively tap the value of project management data, and management decisions lack quantitative support. Progress, submission, and performance data during project execution are stored in a scattered manner, making centralized statistical analysis impossible. There is a lack of quantitative progress monitoring and performance evaluation indicators, and progress display is not intuitive. Production task scheduling, resource allocation, and schedule optimization rely heavily on the experience of management personnel, failing to provide scientific decision support.

[0006] Furthermore, existing general-purpose project management software is poorly adapted to industry needs, failing to align with the production organization and management model of the railway survey and design industry. It also cannot achieve data interoperability with 3D collaborative design and BIM systems, resulting in severe information silos between management and design processes. This fails to fundamentally address the existing management pain points in the industry. Developing a railway design project operation platform and schedule management method adapted to the characteristics of the industry has become an urgent technical problem to be solved.

[0007] The present invention aims to solve the technical problems existing in the prior art. To this end, it proposes a railway design project operation platform and progress management method based on multi-level control. Summary of the Invention

[0008] The purpose of this invention is to provide a railway design project operation platform and progress management method based on multi-level control, so as to solve the technical problems existing in the prior art.

[0009] By adopting the above technical solution, the present invention has the following beneficial effects:

[0010] This invention provides a railway design project operation platform and progress management method based on multi-level control, comprising the following steps:

[0011] Standardized Management of Basic Project Information: A standardized project library, professional library, and task template library are constructed. Basic information such as the full name, abbreviation, project type, and design stage of railway design projects are uniformly and standardizedly defined, generating a unique identifier for each project to achieve traceable management throughout the project lifecycle. The professional library covers all railway design disciplines, setting unified professional codes and naming standards. The task template library covers all design stages of railway design, including feasibility studies, preliminary design, and construction drawings, pre-setting standard task items, task levels, schedule baselines, and hierarchical coordination relationships for each stage.

[0012] Multi-level Project Team Setup and Access Control: Based on the management architecture of railway design projects, a three-tiered management team is established, comprising a institute-level control layer, a project-wide control layer, and a specialized execution layer. Differentiated operational permissions and data access scopes are configured for each level of role. The institute-level control layer includes the supervising dean, vice president, and dispatcher, responsible for the macro-level control of projects across the entire group. The project-wide control layer includes the project manager and deputy project manager, responsible for the full-discipline control of individual projects. The specialized execution layer includes the heads of each specialized line and designers, responsible for the specific execution of tasks within their respective disciplines, forming a clearly defined hierarchical access control system.

[0013] Tiered Task Assignment and Compliance Verification: Based on a standardized task template library, technical work sheets and scheduling notices corresponding to the design phase are generated. Tasks are categorized into three levels: institute-level control, overall control level, and dedicated line control level, clearly defining the management entities and responsibility boundaries for different levels of tasks. When tasks are imported into the platform, the system automatically performs compliance verification, including professional matching verification, schedule compliance verification, and tiered rule verification. After successful verification, the tiered assignment of tasks is completed, synchronizing tasks of different levels to the responsible persons at the corresponding management levels.

[0014] Closed-loop professional data exchange management: For the data delivery needs of upstream and downstream disciplines in railway design, a one-to-one data submission process is established, defining the full-process status rules for data submission, confirmation, return, and modification, and clarifying the operational requirements and time limits for each stage. Based on task hierarchy, differentiated change approval processes are set up: changes to dedicated line control-level tasks are approved by the project overall management, while changes to overall control-level and institute control-level tasks are approved by the institute-level management, achieving closed-loop control and full traceability of the entire data exchange lifecycle.

[0015] Multi-dimensional intelligent message reminders: Based on task classification and deadlines, a tiered early warning message reminder mechanism is constructed. Different reminder timings, reminder recipients, and push frequencies are set for tasks at the institute control level, overall control level, and dedicated line control level. Task reminders, status change notifications, and overdue warning information are pushed simultaneously through multiple channels such as the enterprise's internal office system, WeChat, and SMS to ensure that task node requirements reach the corresponding responsible persons in a timely manner.

[0016] Visualized progress control and dynamic early warning: Based on task execution status and data exchange progress, a multi-color light indicator mechanism (green, yellow, red, and purple) is used to visually display task progress, allowing managers to intuitively grasp the project execution status. Real-time calculation of task progress deviation rate quantifies the degree of task lag. When the deviation rate exceeds a preset threshold, a corresponding level of early warning is triggered and simultaneously pushed to the responsible person at the corresponding management level, enabling early detection and handling of progress risks.

[0017] Comprehensive Data Statistics and Performance Analysis: Based on the platform's full-process business data, it automatically extracts execution data from four dimensions: project, task, specialty, and personnel. It calculates core performance indicators such as task fulfillment rate, normal submission rate, and late submission rate for each specialty, generating multi-dimensional statistical reports. Based on historical project data, it analyzes the rationality of design cycles for each specialty, optimizes task duration benchmarks, and provides precise data support for production task scheduling, human resource allocation, and management decisions.

[0018] Cross-system data collaboration and integration: Construct standardized data interfaces with 3D collaborative design systems, BIM systems, and enterprise portal systems, define unified data interaction formats and transmission rules, realize automatic push and two-way sharing of basic project information, professional information, task information, and design results information, break down information silos in the design and management stages, and achieve real-time synchronization of design progress and management progress.

[0019] This invention provides a railway design project operation platform based on multi-level control, adopting a five-layer architecture design, from bottom to top: basic data layer, business logic layer, control execution layer, and presentation layer, with an independent cross-system interface layer. The specific architecture is as follows:

[0020] Basic Data Layer: The core data foundation of the platform, used to store and manage standardized project libraries, professional libraries, task template libraries, personnel information libraries, project business databases, and operation log databases, providing standardized basic data support for the entire process of platform operation and ensuring unified storage and secure management of all business data.

[0021] Business Logic Layer: The core processing hub of the platform, communicating and connecting with the basic data layer. It encapsulates the processing rules and logic of all core business operations of the platform, including project management logic, team and permission management logic, task management logic, data exchange process logic, message push logic, progress calculation and early warning logic, data analysis logic, and interface interaction logic, ensuring that all business operations comply with the preset management rules and permission system.

[0022] Control and Execution Layer: The core functional carrier of the platform, communicating and connecting with the business logic layer. It includes eight core functional modules: project management, team building, hierarchical task assignment, data exchange, message reminder, progress visualization, statistical analysis, and system management. These modules work together to achieve full-process control of railway design projects from creation to archiving.

[0023] Presentation Layer: The platform's interactive interface with users, communicating with the management and execution layer. Based on the logged-in user's role and permissions, it adaptively displays the corresponding functional interfaces and business data, providing differentiated operation interfaces for the institute-level management and control layer, the overall project management and control layer, and the professional dedicated line execution layer, ensuring that users at different levels can only access functions and data within their authorized scope.

[0024] Cross-system interface layer: The interaction bridge between the platform and external systems. It communicates with the business logic layer, external 3D collaborative design system, BIM system and enterprise portal system respectively. It has built-in standardized data conversion rules and communication protocols to achieve seamless connection, two-way data sharing and real-time synchronization between the platform and external systems.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. A multi-level management and control system and standardized foundation adapted to the industry have been established. By building a three-tiered hierarchical management and control system consisting of a college-level management and control layer, a project-wide management and control layer, and a professional dedicated line execution layer, the management responsibilities and authority of each level are clearly defined, enabling the hierarchical assignment, approval, and early warning of tasks. This fundamentally solves the problems of unclear authority division and weak overall project control in the traditional model. At the same time, standardized project libraries, professional libraries, and task template libraries have been established to achieve unified and standardized management of basic project information, laying a solid foundation for cross-project data statistics and experience reuse.

[0027] 2. A closed-loop professional collaboration and intelligent risk control have been achieved. By designing a closed-loop management process for the mutual transfer of professional documents, defining full-process status rules and a hierarchical approval mechanism, the delivery of professional documents between different levels is traceable and controllable, effectively avoiding industry problems such as document version confusion, inter-professional buck-passing, and design rework. At the same time, a multi-dimensional intelligent hierarchical message reminder mechanism has been built, setting differentiated reminder rules for tasks of different levels, realizing early reminders for task nodes and graded warnings for overdue tasks, effectively preventing the risk of project delays.

[0028] 3. It fully leverages the value of data, providing precise decision-making support. A multi-color indicator mechanism enables visualized progress control, while quantitative calculation formulas such as progress deviation rate, professional fulfillment rate, and overall project completion rate enable dynamic monitoring of project progress and quantitative evaluation of professional efficiency. It can automatically generate multi-dimensional statistical reports, providing precise data support for production task scheduling, resource allocation, and schedule optimization, fully leveraging the core value of project management data.

[0029] 4. It promotes the deep integration of management and design, possessing extremely high industry promotion value. By constructing standardized data interfaces with 3D collaborative design systems and BIM systems, it achieves automatic push and two-way sharing of basic information, task information, and design result information, breaking down information silos between management and design processes. The platform is fully aligned with the production organization and management model of the railway survey and design industry, exhibiting strong industry adaptability compared to general-purpose project management software. Practical application verification has shown that it can significantly improve the fulfillment rate of professional tasks, greatly reduce management communication costs, and minimize design rework, possessing extremely high industry promotion and application value.

[0036] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0037] This invention discloses a railway design project operation platform and progress management method based on multi-level control. Targeting the production organization and management characteristics of the railway survey and design industry, it constructs a three-level hierarchical control system consisting of an institute-level control layer, a project-wide control layer, and a specialized line execution layer. This achieves closed-loop information management of the entire process of railway design projects, from project creation, team building, task assignment, data exchange, progress control to data analysis. At the same time, it realizes data interoperability with BIM systems and 3D collaborative design systems through standardized interfaces, comprehensively solving the industry pain points in traditional management models.

[0038] The operating platform of this invention adopts a four-layer architecture plus a cross-system interface layer. From bottom to top, it consists of a basic data layer, a business logic layer, a control and execution layer, and a presentation layer, along with a separate cross-system interface layer. The overall architecture is shown in the attached figure. Figure 1 As shown in the diagram. The platform is structured as follows: The basic data layer is the core data foundation, storing standardized project libraries, professional libraries, task template libraries, and other core basic data, as well as business data and operation logs throughout the entire project process. The business logic layer is the platform's core brain, encapsulating all business rules and processing logic to ensure all business operations comply with preset management rules and permission systems. The control and execution layer is the platform's core functional carrier, containing eight functional modules for full-process control, through which users complete corresponding business operations. The presentation layer is the platform's interactive interface with users, adaptively displaying corresponding functional interfaces and data based on user role permissions, ensuring that users at different levels can only access functions and data within their authorized scope. The cross-system interface layer enables standardized data interaction between the platform and external design systems and enterprise management systems, breaking down information silos.

[0039] The progress management method of this invention comprises eight core steps, forming a complete management closed loop. The overall process is shown in the appendix. Figure 2As shown: First, standardized basic data management lays a unified foundation for project management; second, multi-level team building and permission configuration construct a three-tiered control system adapted to industry characteristics; third, hierarchical task assignment and compliance verification ensure accurate task assignment and standardized management; fourth, closed-loop professional data exchange management enables full-process control of inter-professional collaboration; fifth, multi-dimensional intelligent message reminders enable early prevention of task milestones; sixth, visualized progress control and dynamic early warning enable real-time monitoring of project progress and risk management; seventh, comprehensive data statistics and performance analysis enable data value mining and decision support; and eighth, cross-system data collaboration and integration achieve deep integration of management and design.

[0041] Explanation of core calculation formulas

[0042] This invention achieves accurate evaluation of project progress and professional effectiveness through a quantitative calculation formula. The core formula is as follows:

[0043] The calculation formula for the task progress deviation rate is as follows: This invention uses the task progress deviation rate to quantitatively evaluate the progress of a task.

[0044] (1)

[0045] in, This refers to the task progress deviation rate. The actual duration of the task, in days; The total planned duration of the task is in days. When ≤0, it indicates that the task progress is in line with the plan or completed ahead of schedule; when 0 < When the percentage is ≤20%, it indicates a slight delay in the task, triggering a yellow alert and pushing it to the overall project management level; when 20% < When the completion rate is ≤50%, it indicates a moderate delay in the task, triggering an orange alert, which is simultaneously pushed to the overall project management level and the institute-level management level; when... A progress rate exceeding 50% indicates a serious delay in the task, triggering a red alert and sending it to the institute-level management and project supervisor. This formula enables quantitative assessment and tiered early warning of task progress, ensuring the timely detection and handling of schedule risks.

[0046] The professional task fulfillment rate is a core indicator for quantitatively evaluating the performance of each professional task. The calculation formula is shown in formula (2):

[0047] (2)

[0048] in, For the first time in the statistical period The task completion rate for each profession This refers to the number of effective tasks completed by this specialty within the statistical period, according to the planned construction period. This refers to the total number of tasks to be completed for this major within the statistical period. Furthermore, this invention defines the normal submission rate and the delayed submission rate, calculated using formulas (3) and (4):

[0049] (3)

[0050] (4)

[0051] in, For the first The normal submission rate of materials for each major This refers to the number of documents submitted by the major within the planned timeframe during the statistical period. For the first The rate of delayed submission of materials for each major This refers to the number of documents submitted by this major outside the planned timeframe within the statistical period, and must meet the following conditions: + ≤100%, the difference represents the percentage of returned materials. These core indicators enable a quantitative assessment of the execution of designs across various disciplines, providing precise data support for professional performance evaluation, resource allocation, and schedule optimization.

[0052] The formula for calculating the overall project progress completion rate is as follows: This invention defines the overall project progress completion rate for the assessment of the overall project progress, and the calculation formula is shown in Equation (5):

[0053] (5)

[0054] in, The overall project progress completion rate. This represents the total number of tasks included in the project. Let be the weight value of the j-th task. It is preset according to the task level (hospital control level, overall control level, dedicated line control level) and importance. The weight of the hospital control level task is the highest, followed by the overall control level task, and the weight of the dedicated line control level task is the lowest. The completion percentage of the j-th task; the number of completed tasks. =1, unfinished task This represents the percentage of actual progress completed, with a value ranging from 0 to 1. ≤1. This formula comprehensively considers the importance of tasks at different levels, accurately calculates the overall progress of the project, avoids the deviation of the traditional simple calculation of progress based on the number of tasks, and is more in line with the actual management of railway design projects.

[0055] Example 1

[0056] Full-process management and control of the feasibility study and design phase of new railway projects

[0057] This embodiment uses the feasibility study and design phase of a newly built national railway trunk line project as an application scenario. The platform and method of this invention are used to achieve multi-level control over the entire project process. The specific implementation process is as follows:

[0058] 1. Standardized Management of Basic Project Information

[0059] Hospital-level management personnel attach through the platform Figure 1 The institute-level management interface at the middle layer allows for the creation of new railway projects. Basic information such as the project's full name, abbreviation, project type, region, supervising leader, and design stage is entered. The system automatically generates a unique identifier for each project and incorporates it into the standardized project database at the basic data layer. Simultaneously, institute-level management personnel maintain a standardized professional database for railway design, encompassing core railway design specialties such as track, bridges, tunnels, geology, roadbed, stations, locomotives, rolling stock, architecture, structure, water supply and drainage, HVAC, power, communications, signaling, and economics. Each specialty has a unique professional code and naming convention. The system also maintains a standardized task template database for the feasibility study and design phase. This database contains standardized content for each specialty at the feasibility study and design phase, including standard task items, task classifications, schedule baselines, and hierarchical coordination relationships, ensuring consistent task management standards across different projects and adhering to the attached guidelines for the overall process. Figure 2 The steps are shown.

[0060] 2. Multi-level project team formation and permission configuration

[0061] Institute-level management personnel assign institute-level management roles such as Dean in charge, Vice President in charge, and Institute Dispatcher to the project on the platform, and allocate institute-level management permissions. They can view and manage institute-level and overall control-level tasks for the project. Simultaneously, institute-level management personnel designate a project manager and deputy project manager for the project, assigning overall project management permissions. The project manager can view all tasks across all disciplines, edit overall control-level and dedicated line control-level tasks, and approve dedicated line change requests. The project manager assigns dedicated line managers to each discipline on the platform, forms project professional teams, and assigns professional dedicated line execution-level permissions to each dedicated line manager. They can only view and operate dedicated line control-level tasks related to their own discipline and submit design documents and change requests for their own discipline. The system is based on... Figure 3 The permission hierarchy shown automatically generates a tiered permission control system. All operations are subject to permission rules, ensuring that roles at each level can only perform operations within their authorized scope.

[0062] 3. Tiered task assignment and compliance verification

[0063] Based on the standardized task template library from the feasibility study and design phase, the project generates a technical work sheet for the feasibility study phase. Tasks in the technical work sheet are categorized and marked: core tasks affecting the overall project progress, such as feasibility study report preparation, determination of major technical standards, and route selection, are marked as institute-controlled; tasks related to the overall design principles and major scheme selection for each specialty are marked as overall control; and execution tasks such as detailed design calculations and drawing preparation for each specialty are marked as dedicated line control. The project team imports the marked technical work sheet into the platform. The system automatically performs compliance checks through the hierarchical task assignment module at the control and execution layer: verifying whether the specialty corresponding to the task exists in the project specialty library, whether the task's classification conforms to the rules, and whether the task's schedule setting meets the template benchmark requirements. After all checks pass, the system automatically completes the hierarchical assignment of tasks, synchronizing institute-controlled tasks to institute-level management personnel, overall control tasks to the project team, and dedicated line control tasks to the corresponding dedicated line managers. If a check fails, the system returns specific exceptions, terminates the task assignment process, and requires the project team to revise and resubmit for verification.

[0064] 4. Closed-loop management of professional data exchange

[0065] After the task is assigned, the heads of each specialized line carry out design work according to the task plan. After completing the corresponding design documents, they submit them to the corresponding downstream specialties through the platform's document exchange module. For example, after the railway alignment specialty completes the horizontal and vertical profile design documents, it submits them to downstream specialties such as bridges, tunnels, geology, and roadbeds on the platform. The system automatically records information such as the submitter, submission time, and document version, generates an operation log, and triggers a document receipt reminder for the downstream specialties. After receiving the reminder, the head of the downstream specialty previews and downloads the documents on the platform, reviews them, and if the documents meet the requirements, completes the confirmation operation on the platform. The system updates the task status to "completed" and simultaneously pushes a confirmation notification to the upstream specialty. If the documents do not meet the requirements, they are returned on the platform with detailed modification comments. The system updates the task status to "returned" and pushes a return notification to the upstream specialty. The upstream specialty can then resubmit the revised documents. If modifications to confirmed data are required, a change request must be submitted according to the task level: change requests for dedicated line control level tasks are approved by the overall project team; change requests for overall control level tasks are approved by the institute-level management personnel; and change requests for institute-level control level tasks are approved by the project supervisor. Only after approval can the data be modified, triggering the confirmation process again. The overall process follows the attached... Figure 4 The status transition rules shown enable closed-loop management of the entire lifecycle of data exchange.

[0066] 5. Multi-dimensional intelligent message reminders and progress control

[0067] The system monitors the deadlines and execution status of all tasks in real time, and pushes reminders according to a tiered early warning system: For tasks under institute control, reminders are pushed to the institute's scheduling and overall project management 3 days before the deadline, and a red alert is pushed in real time after the deadline; for tasks under overall project control, reminders are pushed to the overall project management 2 days before the deadline, and an orange alert is pushed to the institute's scheduling; for tasks under dedicated line control, reminders are pushed to the corresponding dedicated line manager 1 day before the deadline, and a yellow alert is pushed to the overall project management after the deadline. Simultaneously, the system calculates the progress deviation rate of each task in real time through a progress calculation module, using a multi-color light (green, yellow, red, purple) indicator mechanism to visually display the execution status of each task on the progress dashboard: green indicates the task is completed normally, yellow indicates it is not completed near the deadline, red indicates it is not completed on time, and purple indicates the data has been returned. When the task progress deviation rate exceeds a preset threshold, the system... Figure 5 The warning push module shown automatically triggers warnings of the corresponding level and pushes them to the responsible persons at the corresponding management level to ensure timely handling of progress risks.

[0068] 6. Data statistical analysis and cross-system collaboration

[0069] During project execution, institute-level management and project managers can initiate statistical queries at any time through the platform. The system automatically extracts project business data through the statistical analysis module, calculates core indicators such as task fulfillment rate, normal submission rate, and late submission rate for each specialty, and generates multi-dimensional statistical reports such as project progress reports for the feasibility study stage and specialty execution reports, providing data support for project management decisions. Simultaneously, the platform provides supplementary... Figure 1 The cross-system interface layer in the system enables bidirectional data synchronization with the 3D collaborative design system and BIM system. It automatically pushes project task information and professional information to the design system, and automatically synchronizes drawing versions and design progress information in the design system to the management platform, thereby achieving progress synchronization between design and management and breaking down information silos.

[0070] Example 2

[0071] Data exchange and progress early warning implementation during the preliminary design phase of railway projects under construction.

[0072] This embodiment uses the preliminary design phase of a passenger dedicated railway project under construction as an application scenario. It focuses on utilizing the closed-loop data exchange management and intelligent hierarchical early warning functions of this invention to solve the problems of untimely data submission, version inconsistencies, and inability to prevent and control progress risks in the traditional model. The specific implementation process is as follows:

[0073] 1. Project and Team Initialization

[0074] Institute-level management personnel complete the basic information maintenance of the project under construction on the platform, include it in the standardized project library, and, based on the task template library of the preliminary design phase, complete the configuration of the project professional library and the import and hierarchical labeling of the technical work sheets for the preliminary design phase. Simultaneously, based on the attached... Figure 3 The illustrated permission hierarchy structure completes the establishment and permission configuration of the project's three-tier management team, clearly defining the roles and permissions of the institute-level control layer, the overall project control layer, and the execution layers of each professional specialization, ensuring that the operations of personnel at each level comply with the permission rules, and that the overall process follows the attached... Figure 2 The steps are shown.

[0075] 2. Closed-loop management of the entire data exchange process

[0076] To address the frequent data exchange and high collaboration requirements among different disciplines during the preliminary design phase, this embodiment fully utilizes the platform's closed-loop data exchange management function. First, the overall project team clearly defines the sequential data submission process, delivery milestones, and data requirements for each discipline in the technical work sheet. Based on the technical work sheet, the system automatically generates a list of tasks to be submitted for each discipline and pushes it to the to-do list of the corresponding project manager. After completing their design data, the preceding discipline submits the corresponding task data on the platform. Only the final version of the design data must be submitted; interim versions are not allowed to prevent rework caused by subsequent disciplines designing based on interim versions. After data submission, the system automatically sends data receipt reminders to the project managers of the following disciplines via multiple channels, including SMS, WeChat Work, and internal office systems, ensuring timely delivery of reminders. Upon receiving the notification, the next-order specialty must complete the review and confirmation of the materials within 24 hours. If the materials meet the design requirements, confirmation is completed on the platform, and the system automatically records the confirmation information, thus completing the material exchange process. If the materials do not meet the requirements, they are returned on the platform, with detailed explanations of the reasons for return and modification requirements. The system sends a return notification to the previous-order specialty, which must then revise the materials according to the modification suggestions and resubmit them. For material change requests during the preliminary design phase, the system strictly implements a tiered approval mechanism: If confirmed materials for a dedicated line control-level task need modification, the dedicated line manager submits a change request, detailing the reasons for the change and its scope of impact, for overall project approval; if confirmed materials for overall control-level or institute control-level tasks need modification, the change request must be submitted level by level to the institute-level management for approval before modification can proceed, avoiding design rework and project delays caused by arbitrary changes. Meanwhile, the system records all operation logs for the entire data exchange process, including all information such as the operator, time, content, and attachment version for submissions, confirmations, returns, and changes. This ensures full traceability and allows for quick identification of the responsible party in case of problems, effectively preventing buck-passing between professionals. The overall process follows the attached... Figure 4 The state transition rules are shown.

[0077] 3. Intelligent hierarchical early warning and dynamic progress control

[0078] In this embodiment, the system executes differentiated early warning rules based on task classification and deadlines: For core tasks at the institute control level, such as preliminary design general descriptions and major technical solution demonstrations, three reminders are set up in advance: 5 days, 3 days, and 1 day in advance, respectively pushed to the institute's scheduling department, the project manager, and the supervising leader. A red alert is triggered upon delay, and warning information is pushed daily. For tasks at the overall control level, such as professional design principles and major work point plans, two reminders are set up in advance: 3 days and 1 day in advance, pushed to the project manager. An orange alert is triggered upon delay, pushed to the institute's scheduling department. For tasks at the dedicated line control level, such as the submission of detailed design documents for each specialty, two reminders are set up in advance: 2 days and 1 day in advance, pushed to the corresponding dedicated line manager. A yellow alert is triggered upon delay, pushed to the project manager. Simultaneously, the system uses appendices... Figure 5 The progress calculation module shown calculates the progress deviation rate of each task and the overall project completion rate in real time. The project progress dashboard uses multi-colored lights to visually display the execution status of all tasks, allowing project managers and college-level control personnel to monitor the overall project progress and the execution status of each specialty in real time. When multiple tasks in a specialty are overdue, or when the task progress deviation rate exceeds a preset threshold, the system automatically triggers an alert and pushes it to the corresponding responsible person. The project manager can then intervene promptly to coordinate and resolve the progress delays.

[0079] 4. Project authorization application in business travel scenarios

[0080] To address the issue of railway designers frequently traveling and being unable to promptly handle platform operations, this embodiment utilizes the platform's project authorization function. Before traveling, the heads of each specialized line can temporarily authorize designated designers within their specialty to submit, confirm, and request change requests for relevant materials, setting the validity period and scope of the authorization. During the authorization period, the authorized personnel can perform corresponding operations within the authorized scope, and the system synchronously records all authorized operation logs. Authorization is automatically revoked upon expiration. This function effectively solves the problems of untimely material submission and stalled approval processes caused by designers' travel, ensuring the normal progress of project workflows.

[0082] Multi-dimensional data analysis and BIM collaborative implementation of railway design projects

[0083] This embodiment uses the batch management of multiple railway design projects within a group company as an application scenario. It focuses on utilizing the full-dimensional data statistical analysis and cross-system BIM collaboration functions of this invention to achieve centralized control and data value mining of multiple projects at the group level, while simultaneously realizing deep integration of management and design. The specific implementation process is as follows:

[0084] 1. Centralized management and control of multiple projects

[0085] The hospital-level management team uses the platform to attach Figure 1 The centrally located institute-level control terminal provides centralized management of all ongoing and newly constructed railway design projects within the group. All projects are incorporated into a standardized project database, employing unified professional databases, task template databases, and management standards to ensure consistent management across all projects. Institute-level control personnel can view real-time key data such as overall project progress completion rate, task fulfillment rate for each specialty, number of overdue tasks, and early warning information through the platform's project overview dashboard. They can also access detailed progress information, task execution details, and data exchange records for individual projects, enabling remote centralized control of all projects at the group level. This eliminates the need for offline meetings and hierarchical reporting to obtain project progress information, significantly improving management efficiency at the group level. The overall process follows the attached... Figure 2 The steps are shown.

[0086] 2. Comprehensive data statistics and performance analysis

[0087] The platform leverages end-to-end business data from all projects to enable multi-dimensional statistical analysis and performance evaluation. First, the system automatically extracts task execution data from all projects, categorized by statistical period (monthly, quarterly, and annual). Using core calculation formulas, it calculates key performance indicators for each specialty, such as task fulfillment rate, document submission rate, and late submission rate, generating a group-level professional performance analysis report to quantitatively assess the design execution capabilities of each specialty. For specialties with consistently low task fulfillment rates, group management can conduct targeted management optimization and skills training to improve professional design capabilities. For specialties with high fulfillment rates and high collaboration efficiency, the system summarizes their management experience and promotes its reuse throughout the group. Second, based on historical project task duration data, the system uses big data analytics to analyze the reasonable design cycle for each specialty and task type, optimizing the duration benchmark in the standardized task template library. This provides scientific data reference for setting task durations for subsequent projects, avoiding the problems of experience-based and unreasonable duration settings in traditional models. Meanwhile, the system allows for customized statistical queries based on multiple dimensions such as project type, design stage, region, supervisor, and overall project, automatically generating standardized statistical reports. This provides comprehensive data support for the group's production task scheduling, human resource allocation, and business decision-making, fully leveraging the value of project management data. The overall data processing logic follows the attached... Figure 5 The module interaction flow is shown.

[0088] 3. Deep integration with BIM systems and 3D collaborative design systems

[0089] In this embodiment, through platform attachment Figure 1The cross-system interface layer enables seamless integration and bidirectional data sharing with the group's 3D collaborative design system and BIM system. First, the platform automatically pushes basic project information, professional information, task information, and delivery milestone requirements to the 3D collaborative design system and BIM system. Designers can directly view the corresponding task requirements and delivery milestones within the design system without switching between multiple systems, and management requirements can be directly transmitted to the design team. Second, design deliverables, drawing versions, and design progress information completed by designers in the 3D collaborative design system and BIM system are automatically synchronized to the project management platform. The platform updates the execution status of corresponding tasks in real time, allowing managers to monitor the actual progress of the design process without requiring designers to manually report progress information, achieving real-time synchronization between design and management progress. Simultaneously, component information and professional collaboration requirements in the BIM model can be synchronized to the management platform via the interface, triggering corresponding document submission processes and task reminders, achieving deep integration of BIM design and project management, and breaking down information silos between management and design processes.

[0090] 4. Continuous optimization of the management system

[0091] The platform continuously collects feedback from users at all levels across the group regarding optimization suggestions for platform functions and management rules. Based on adopted suggestions, the platform's functions and management rules are continuously iterated to ensure that the platform always aligns with the actual needs of the group's production organization and management. Simultaneously, based on the platform's full-process operational data, bottlenecks and difficulties in management processes are analyzed, and management processes and hierarchical control rules are continuously optimized to enhance the digitalization and intelligence level of the group's production organization and management.
