Description

Technical Field

[0001] The present invention relates to the technical field of engineering cost estimation, and in particular to a method, device, equipment and storage medium for managing engineering cost estimation task allocation. Background Art

[0002] Construction cost estimation refers to the professional activity of scientifically estimating, budgeting, accounting, and controlling construction costs throughout the lifecycle of a construction project, based on reference data such as engineering design documents, market price information, and pricing specifications. Typically, construction cost estimation tasks involve a massive workload. Implementing intelligent allocation and management of construction cost estimation tasks in the construction industry can significantly improve overall project efficiency, ensure the quality of cost estimation results, and optimize dynamic resource allocation. This provides accurate investment, design, construction, and settlement data for project implementation, ensuring the smooth completion of the project.

[0003] Traditional engineering cost estimation task allocation is usually done manually. Management personnel will assign the estimation contents of different parts of different engineering cost estimation tasks to corresponding engineering cost estimation personnel based on their experience. However, this task allocation method faces great limitations in some scenarios: (1) Different types of engineering projects have different estimation contents (for example, the focus of residential projects is on the standardization of apartment types and the compilation of decoration lists, the focus of municipal road projects is on the calculation of earthwork and pipeline integration, and industrial plant projects are more focused on the calculation of steel structure quantities and equipment foundation costs, etc.), and different engineering cost estimation personnel have different estimation capabilities and estimation content emphases. When actually allocating estimation tasks, the influence of the above two aspects needs to be considered to ensure the estimation efficiency and quality. The traditional manual allocation method is very difficult; (2) The engineering cost estimation tasks of different engineering projects have different project deadlines, and the traditional manual allocation method is difficult to use. It is difficult to control the progress of the cost estimation task execution, especially during the peak period of engineering project cost estimation demand. The engineering cost estimation unit will perform the cost estimation tasks of multiple projects at the same time. In the case of limited engineering cost estimation personnel, it is impossible to accurately control the cost estimation tasks of each project to maintain the most reasonable cost estimation speed. The cost estimation progress is often "loose at the beginning and tight at the end" or "tight at the beginning and loose at the end", which affects the overall efficiency and quality of the cost estimation. It also makes it difficult to plan the number and type of cost estimation personnel for each engineering project. (3) Usually, the cost estimation task is divided into stages (such as the scheme design stage, the preliminary design stage, the construction drawing stage, etc.), and the cost estimation of each stage requires the relevant design unit to provide data to achieve it. If the data provided by the design unit is delayed, it is likely to affect the progress of the cost estimation unit and the scheduling of the overall cost estimation resources. The traditional manual allocation method is insufficient to handle emergencies in special scenarios.

[0004] Therefore, how to improve the scientificity and rationality of the planning of engineering cost estimating personnel allocation strategies and engineering cost estimating execution strategies for different engineering cost estimating tasks, and provide a certain degree of risk resistance and adjustment capabilities for delays in estimation data on the premise of improving the overall estimation efficiency and quality of engineering cost estimating units, is a technical problem that needs to be solved urgently.

[0076] It should be noted that the traditional allocation of engineering cost estimation tasks is usually done manually. Management personnel will assign the estimation contents of different parts of different engineering cost estimation tasks to corresponding engineering cost estimation personnel based on their experience. However, this task allocation method faces great limitations in some scenarios: (1) Different types of engineering projects have different estimation contents (for example, the focus of residential projects is on the standardization of apartment quantity and the compilation of decoration lists, the focus of municipal road projects is on the calculation of earthwork quantity and pipeline integration, and industrial plant projects are more focused on the calculation of steel structure quantity and equipment foundation cost, etc.), and different engineering cost estimation personnel have different estimation capabilities and estimation content emphases. When actually allocating estimation tasks, it is necessary to consider the influence of the above two aspects to ensure the estimation efficiency and quality. The traditional manual allocation method is very difficult; (2) The engineering cost estimation tasks of different engineering projects have different project deadlines, and the traditional manual allocation method has different requirements. The allocation method makes it difficult to control the progress of the cost estimation task execution, especially during the peak period of engineering project cost estimation demand. The engineering cost estimation unit will perform the cost estimation tasks of multiple projects at the same time. In the case of limited engineering cost estimation personnel, it is impossible to accurately control the cost estimation tasks of each project to maintain the most reasonable cost estimation speed. It often faces the cost estimation progress of "loose at the beginning and tight at the end" or "tight at the beginning and loose at the end", which affects the overall efficiency and quality of cost estimation. It also makes it difficult to plan the number and type of cost estimation personnel for each engineering project; (3) Usually, the cost estimation task is divided into stages (such as the scheme design stage, the preliminary design stage, the construction drawing stage, etc.), and the cost estimation of each stage requires the relevant design unit to provide data to achieve it. If the data provided by the design unit is delayed, it is likely to affect the progress of the engineering cost estimation unit and the scheduling of global cost estimation resources. The traditional manual allocation method is insufficient to handle emergencies in special scenarios.

[0077] In order to solve the above problems, this embodiment analyzes the engineering cost estimation tasks, performs the first update action on the engineering cost estimation task list, considers the estimation time intervals of different engineering cost estimation personnel combinations in the execution of different types of estimation tasks, takes the estimation quality and estimation period as the constraint condition set, takes the lowest handover cost of the estimation stage of the engineering cost estimation task as the optimization goal, optimizes the solution of the estimation strategy, realizes the second update of the engineering cost estimation task list and executes the estimation task, and then uses its own delay risk elimination ability or re-plans the estimation strategy and updates the engineering calculation task list for the third time. While improving the scientificity and rationality of the planning of the estimation strategy of engineering cost estimation personnel for different engineering cost estimation tasks, it provides a certain degree of risk resistance and adjustment capabilities for delays in estimation data.

In this way, the estimation project identifier and project description text can be extracted according to the associated information of the target estimation project, and the first stage data packet can be imported into the estimation project stage data storage space for subsequent estimation execution.

[0083] In a preferred embodiment, the project description text is parsed to determine the project level information and the calculation task stage division information of the target calculation project, obtain the current project cost calculation task list, and perform a first update action step on the project cost calculation task list using the project importance level and the calculation task stage division information, specifically including:

[0098] On this basis, based on the optimized engineering cost estimation execution strategy, the estimation project identifier of the target estimation project is used to perform a second update action on the engineering cost estimation task list. Using the engineering cost estimation task list after the second update action, the engineering cost estimation task steps are executed, specifically including:
