Description

Technical Field

[0001] The present invention belongs to the technical field of power project management, and in particular relates to a resource planning method and system based on engineering construction elements. Background Art

[0002] There are many common problems in the implementation of conventional engineering projects on the construction site, especially progress management problems. Although the problems have been considered as comprehensively as possible during the project design process, due to various reasons, such as design changes, delayed material supply, insufficient manpower, etc., the project cannot proceed as planned during the actual implementation. In addition, there are many departments involved in the project, and the information exchange and communication between the designer, the constructor, and the supervisor are not smooth, which further affects the progress of the project. This problem is a common problem in engineering projects, but for power engineering construction, such a problem will bring a series of subsequent problems.

[0003] The prior art also has relevant solutions to this problem. For example, the invention patent "Digital Engineering Progress Management Method, System, Device and Storage Medium" with patent number 202310985621.9 discloses a digital engineering progress management method including: receiving construction plan information of the construction project to be processed; the construction plan information includes several construction tasks, and the construction tasks include the following record items: construction content information, construction time information, construction location information and engineering supervision personnel information; receiving sorting instructions; responding to the sorting instructions, for each of the construction tasks with the same engineering supervision personnel information, sorting each of the construction tasks in sequence according to the construction time information; generating corresponding reminder information for each of the sorted construction tasks; and sending each of the reminder information with the same engineering supervision personnel information to the first client corresponding to the engineering supervision personnel in sequence and at regular intervals. It enables the supervision unit staff to obtain accurate time and location for on-site supervision according to the actual construction situation, thereby improving work efficiency.

[0004] However, such a technical solution is purely theoretical and can only serve as a reminder. However, once the project cannot be advanced due to objective reasons, Party A will not be able to know the actual reason.

[0005] In addition, there are authorized patents in the prior art: the invention patent with patent number CN202011163682.X "A three-dimensional engineering progress management method assisted by augmented reality technology" uses an augmented reality device with a depth sensor to automatically perform a spatial scan of the construction environment, and after the scan is completed, the current engineering progress is stored in the form of a virtual space grid and distinguished by time tags; when it is necessary to obtain the engineering progress at a specified time, the engineering progress at the specified time is read out again in the form of the virtual space grid according to the time tag corresponding to the specified time, and displayed in the form of a virtual graphic. It has the advantages of not requiring BIM modeling, and can use an augmented reality device with a depth sensor to model the on-site engineering in real time, and can measure the engineering progress between two time points.

[0006] Such technical solutions manage the progress of project engineering through virtual space modeling. However, in reality, most of these management tasks are just paper talk. For example, even if a complete plan has been made, it is impossible to match specific staff with their corresponding work tasks, resources and required energy consumption on the construction site. Summary of the invention

[0007] Aiming at the problems that the project progress and resource usage cannot be tracked in detail in the prior art during the engineering construction process, and that even if the problem is found, it cannot be effectively managed, the present invention proposes a resource planning system based on engineering construction elements, including a project module, an identity-based login module, a progress management module and a resource management module; in the progress management module of the system, the tasks required to be completed for the entire project are decomposed and placed into decomposition modules with different time tags, and the decomposition modules are connected to the project progress tracking device through wireless devices; the decomposition module decomposes the task into multiple task nodes, and each task node is provided with a personnel work relationship diagram involved in the decomposed task and resource information based on the task node, and the resource information comes from the resource management module; the personnel work relationship diagram records specific personnel information and the interactive behavior guidance between the personnel and resources, and the resource information and personnel information are combined based on the time progress and placed in a milestone table with a timestamp, and the milestone table is saved in the progress management module, and the project is executed according to the milestone table.

[0008] Preferably, the milestone table contains two basic information tables: one is a personnel information table, which contains the unique identification, name, role and ID of the superior of each person involved in the task, to clarify the subordinate relationship between the personnel; the other is a resource information table, which lists in detail the unique identification, name, type and total amount of the resources required for each task. The relationship between these two tables forms a mapping between personnel and required resources. This design method not only comprehensively covers all key information of personnel and resources, but also realizes efficient management and query of information through the relationship between tables, laying a solid foundation for the smooth execution of tasks.

[0009] Preferably, the personnel information also includes identity relationships between personnel, and the identity relationships include management relationships, assistance relationships, and replacement relationships. The information is arranged through multi-level personnel ID fields in the personnel information table.

[0010] Preferably, in the project, each participant is equipped with a wristband as a project progress tracking device, which provides guidance for the workflow of the person, generates resource information only after the resource is placed in the designated location, and records the use of materials in real time when the specific person and the resource interact, and modifies the resource information in the milestone table. The resources include production materials, vehicles, and construction equipment.

[0011] Preferably, the wristband automatically records the behavior trajectory of personnel during working hours, as well as the use of materials, and uploads them to the decomposition module, which obtains the overall workload of a single day from these data, decomposes the overall workload of a single day into workloads based on unit time, and puts them into a milestone table. The decomposed tasks are compared to determine the actual progress.

[0012] The present invention also includes a resource planning method based on engineering construction elements. The system decomposes the entire project task based on unit time and refines it into multiple task nodes. In each task node, a personnel work relationship diagram involving the decomposed task and resource information based on the task node are set. The personnel work relationship diagram records in detail the specific personnel information and the interactive behavior guidance between personnel and resources. According to the workload assigned to each person, the resource information and the personnel information are combined based on the time progress and integrated into a milestone table with a timestamp. The project is executed according to the plan and time nodes in the milestone table, and the settlement is performed after the unit time ends or a single task node ends. The actual progress is compared to see if it is consistent with the milestone table. When the actual progress lags behind the plan in the milestone table, the person relationship in the corresponding task node is modified, and the project is continued according to the modified content.

[0013] Preferably, the workload is calculated as follows:

[0014]

[0015] Where W i is the total workload undertaken by the i-th person;

[0016] C ij is the contribution ratio of the i-th person on the j-th subtask;

[0017] T j is the standard time required for the jth subtask without any influence of the predecessor task time;

[0019] D j is the difficulty coefficient of the jth subtask;

[0020] I j is the importance coefficient of the jth subtask;

[0021] Predecessors (j) represents the set of all predecessor tasks of the jth task;

[0022] △T kj is the time impact of the kth task as a predecessor task on the jth task.

[0023] This formula takes into account the time impact of the predecessor task on the subsequent task by introducing △Tkj, and reflects it in the calculation of workload. If the predecessor task is completed ahead of schedule, the workload of the subsequent task will increase due to the extra time gained; if the predecessor task is delayed, the workload of the subsequent task will decrease due to the loss of time. In this way, each person's workload is not only related to his or her contribution to each task, but also to the time dependency between tasks.

[0024] Preferably, when the daily task decomposition module is provided with an interface for uploading personal information, the information obtained in the interface cannot be deleted. Through such a technical solution, progress control is carried out based on unit time during the construction process, and problems that are behind schedule are marked, and the progress management module determines the reason for the long cycle. Timely punishment is given to personnel who fail to complete the expected tasks for many times. Factors affecting the project can be found in time, and responsibilities can be clarified. In the project module, plans are set up based on all possible problems, and settlements are made according to relevant responsibilities after the project is completed.

[0025] The present invention also includes a storage device, wherein the storage device is used to store a computer program, and the computer program is used to execute the resource planning method based on engineering construction elements.

[0026] Due to the adoption of the technical solution, the specific advantages of the present invention are: by decomposing the entire project task into multiple task nodes based on unit time, and setting a detailed personnel work relationship diagram and resource information, refined management of the project progress is achieved. After the task division, the correlation between multiple tasks is taken into account, and a workload calculation method that considers the influence of the predecessor task time is introduced, so that the workload calculation of each person is more scientific and reasonable, which helps to more accurately evaluate the project progress and personnel performance. The bracelet is used as a project progress tracking device to record the personnel behavior trajectory and material usage information in real time and upload it to the decomposition module. This enables the project team to grasp the project progress in real time, discover problems in time and make adjustments to ensure that the project is advanced as planned, thereby ensuring the smooth realization of the project goals. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings in the following description are only some embodiments of the present invention.

[0028] Figure 1 It is an overall system diagram of a resource planning method and system based on engineering construction elements of the present invention.

[0029] Figure 2 It is a schematic diagram of a workflow in a resource planning method and system based on engineering construction elements of the present invention. DETAILED DESCRIPTION

[0030] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. It is understood that the specific implementation methods described here are only used to explain the relevant content, rather than to limit the present disclosure.

[0031] like Figure 1 , Figure 2As shown, the present invention proposes a resource planning system based on engineering construction elements, including a project module, an identity-based login module, a progress management module and a resource management module; in the progress management module of the system, the tasks required to be completed in the entire project are decomposed into decomposition modules with different time tags, and the decomposition modules are connected to the project progress tracking device through wireless devices; the decomposition module decomposes the task into multiple task nodes, and each task node is provided with a personnel work relationship diagram involved in the decomposed task and resource information based on the task node, and the resource information comes from the resource management module; the personnel work relationship diagram records specific personnel information and the interactive behavior guidance between the personnel and resources, and the resource information and personnel information are combined based on the time progress and placed in a milestone table with a timestamp, and the milestone table is saved in the progress management module, and the project is executed according to the milestone table.

[0032] The milestone table contains two basic information tables: one is a personnel information table, which contains the unique identification, name, role and ID of the superior of each person participating in the task, which is used to clarify the subordinate relationship between personnel; the other is a resource information table, which lists in detail the unique identification, name, type and total amount of resources required for each task. Through the association between these two tables, the personnel and the required resources are mapped. Such a design method not only comprehensively covers all key information of personnel and resources, but also realizes efficient management and query of information through the association between tables, laying a solid foundation for the smooth execution of tasks. The personnel information also includes the identity relationship between personnel, which includes management relationship, assistance relationship and replacement relationship. The information is arranged through the multi-level personnel ID field in the personnel information table. In the project, each participant is equipped with a wristband as a project progress tracking device. The wristband provides guidance for the work flow of the person. The resource information is generated only after the resource is placed in the specified position, and the material usage status is recorded in real time when the specific person and the resource interact, and the resource information is modified in the milestone table. The specific process is: In order to effectively associate the working relationship of personnel performing tasks with the required resource information, the present invention adopts a structured method, covering personnel information, resource information, the relationship between personnel and resources, and the subordinate relationship between personnel. Specifically:

[0033] Get the personnel information table (Person), which includes:

[0034] PersonID: unique identification of a person

[0035] Name: Person's name

[0036] Role: Personnel role

[0037] SupervisorID: Supervisor ID.

[0038] Generate a resource information table (Resource), which includes:

[0039] ResourceID: unique resource identifier

[0040] ResourceName: resource name

[0041] ResourceType: resource type

[0042] Quantity: The quantity of the resource.

[0043] Create a mapping table between personnel and resources (PersonResource)

[0044] PersonID: Person unique identifier (foreign key)

[0045] ResourceID: Resource unique identifier (foreign key)

[0046] QuantityRequired: The required quantity of the resource.

[0047] In this way, in the actual application process, the personnel information is entered first, and a record is created in the Person table for each person involved in the task, including their basic information and the ID of their superior. If the person is already the highest-level person, the ID of the superior is empty.

[0048] Enter resource information and create a record in the Resource table for each resource required for each task, recording the resource name, type, and total quantity in detail. It should be noted that the record needs to be confirmed by the corresponding staff through the wristband before establishing the association between personnel and resources.

[0049] According to the task allocation, allocate the required resources to each person in the PersonResource table, record the person ID, resource ID and required quantity. Ensure that the resource allocation does not exceed the total resource amount, which can be verified by querying the Quantity field in the Resource table.

[0050] If you need to clearly show the hierarchical relationship between people, you can record each subordinate and their corresponding supervisor ID in the Hierarchy table. This step can be automatically constructed by traversing the SupervisorID field in the Person table, or manually entered to reflect the actual organizational structure.

[0051] Under this premise, the bracelet automatically records the behavior trajectory of personnel during working hours, as well as the use of materials, and uploads them to the decomposition module. The decomposition module obtains the overall workload of a single day from these data, decomposes the overall workload of a single day into the workload based on unit time, and puts it into the milestone table. Decompose the tasks for comparison to determine the actual progress. In the actual work process, the system decomposes the entire project task based on unit time and refines it into multiple task nodes; in each task node, a personnel work relationship diagram involving the decomposed task and resource information based on the task node are set. The personnel work relationship diagram records the specific personnel information and the interactive behavior guidance between personnel and resources in detail. According to the workload assigned to each person, the resource information and personnel information are combined based on the time progress and integrated into a milestone table with a timestamp. The project is executed according to the plan and time nodes in the milestone table, and the settlement is carried out after the unit time or the end of a single task node. Compare whether the actual progress is consistent with the milestone table. When the actual progress lags behind the plan in the milestone table, modify the character relationship in the corresponding task node, and continue to execute the project according to the modified content. The calculation method of the workload is as follows:

[0052]

[0053] Where W i is the total workload undertaken by the i-th person;

[0054] C ij is the contribution ratio of the i-th person on the j-th subtask;

[0055] T j is the standard time required for the jth subtask without any influence of the predecessor task time;

[0057] D j is the difficulty coefficient of the jth subtask;

[0058] I j is the importance coefficient of the jth subtask;

[0059] Predecessors (j) represents the set of all predecessor tasks of the jth task;

[0060] △T kj is the time impact of the kth task as a predecessor task on the jth task.

[0061] When the daily task decomposition module has an interface for uploading personal information, the information obtained in the interface cannot be deleted, thus preventing staff from committing fraud in the process.

[0062] Through such work, the workload can be calculated, and it can be determined whether the staff has completed the work within the unit time. If the time spent exceeds the plan in the milestone, or the expected plan cannot be completed within the unit time, it is necessary to determine whether the time gap can be made up in the subsequent work. During the construction process, progress control is carried out based on unit time, and problems that are behind schedule are marked. The progress management module determines the reason for the long cycle. Timely punishment is given to personnel who have failed to complete the expected tasks many times. The factors affecting the project can be found in time, and the responsibilities can be clarified. In particular, the reasons why the subsequent work was not completed as planned due to the delay of the previous work can be found, and the actual responsibility relationship can be clarified. At the same time, in the project module, there are plans based on all possible problems, and settlement is made according to the relevant responsibilities after the project is completed.

[0063] The present invention also includes a storage device, wherein the storage device is used to store a computer program, and the computer program is used to execute the resource planning method based on engineering construction elements.
