Description

Visual decomposition method and system for engineering management

Technical Field

The application relates to the technical field of engineering management, in particular to a visual decomposition method and a visual decomposition system for engineering management.

Background

The traditional project management mode is that project progress management is conducted through a total progress plan and a staged progress plan, and project quality acceptance management is conducted through inspection batch division. The conventional project management method mainly has the following defects:

a. the schedule planning standards are not uniform, and the relevance of the total schedule and the staged schedule is easy to generate conflict only by a manual judgment mode;

b. the relevance between the inspection batch division and the progress plan is not strong, and the inspection batch division and the progress plan are determined by adopting a manual interpretation mode, so that the quality acceptance data of the inspection batch are difficult to be automatically related to the progress plan through the relevance, and the completion condition of the progress plan cannot be automatically judged according to the acceptance condition of the inspection batch;

c. the inspection batch division and the field construction are difficult to be consistent, particularly in railway station houses and large public buildings, as the multi-working-surface flow construction is adopted, the working surface is easily affected by external factors, and the granularity and the level management of the field actual inspection and inspection batch division are more inconsistent;

in the aspect of BIM (namely building information model, building Information Modeling) application, since the schedule planning standards are not uniform, the BIM model and the schedule are difficult to be automatically associated in a mode of giving parameters and increasing codes, after the schedule is required to be processed, the BIM model is manually associated, and the schedule is changed, so that more association relations are invalid; meanwhile, BIM model is difficult to be related with quality acceptance data; for the above reasons, in the actual project management process, the BIM model is difficult to combine with the business management process.

The management mode based on WBS (i.e. work decomposition structure, work Breakdown Structure) is mostly used for highway engineering or railway station front engineering, and the WBS directory tree is decomposed to a single component level first by combining EBS (i.e. engineering system decomposition structure, engineering Breakdown Structure) decomposition and process decomposition, so that the process of the component is decomposed; and using the WBS directory tree as a basis for developing work of the services such as progress, quality, metering and the like. The management mode based on WBS mainly has the following defects:

a. aiming at railway station house engineering or large public building engineering, fixed-level EBS decomposition and process decomposition are difficult to cover flexible business requirements of projects in terms of progress, quality and the like;

b. the engineering of railway station houses and the like involves a plurality of specialized types, and the construction types of a few pile foundations, structural columns, electromechanical equipment and the like are not divided according to the hierarchy of single components, so that progress management work is difficult to develop through a WBS;

the EBS decomposition in the WBS directory tree is difficult to be used as a checking batch part for quality acceptance due to inconsistent division standards, and the WBS directory tree with a fixed level is difficult to be consistent with a construction site, so that quality acceptance work is difficult to be carried out through the WBS;

d. compared with the traditional project management mode, because the EBS is subjected to standardized decomposition in the WBS directory tree, the automatic association of the WBS directory tree and the BIM model is easier; however, since the WBS directory tree cannot meet the business requirements in terms of progress, quality, etc., the BIM model is still difficult to combine with the business management process.

Accordingly, there is an urgent need to develop a visual decomposition method and system for engineering management to efficiently solve one or more of the above-mentioned problems.

Optionally, in step S4, the visual decomposition method for engineering management of the present embodiment establishes a grid space using the elevation axis network information of the BIM model.

The following describes a visual decomposition method for engineering management in this embodiment in detail:

the decomposition method of the embodiment comprises the following steps: EBS entity structure decomposition, binding of EBS and grid space, binding of WBS procedure decomposition, scheduling of EBS and WBS procedure, calculating grid space scheduling and calculating EBS completion scheduling ratio; the process completion conditions of the current area are reflected through the colors of different grids in the grid space, and then the progress completion percentage of each project node is gradually and upwardly calculated through the EBS, and the progress visualization based on the grid space is realized, so that the actual project progress of the whole project is controlled.

The first step: referring to FIG. 2, an EBS engineering node type is created in which a special type "floor" represents a bindable grid space and a "sub-division engineering" represents a bindable procedure.

Second, referring to fig. 3, an EBS engineering decomposition template is created for dividing the engineering whole frame foundation as a basic template for engineering entity structure decomposition.

Third, referring to fig. 4, an entity decomposition structure conforming to the project is generated according to the EBS project decomposition template. Wherein, the subnodes with special nodes of 'floors' and 'subsub engineering' can be correspondingly bound with grid space and procedures.

Fourth, referring to FIG. 5, the WBS process template is used to bind with a special node "sub-engineering" in the EBS. The end nodes under the EBS nodes after binding will inherit the corresponding process steps by default. Different colors can be set in each process, and finally, the process steps of expressing the grid in the grid space can be reflected.

Fifth, see schedule plan in fig. 6. The EBS and process are combined to form a complete composite structure tree that can bind "planned start", "planned complete" and "actual complete" times. The "actual completion" time is taken to mean that the process or EBS node has completed. All completion times are typically extrapolated step-wise upward from the end node completion time. The figure 6 shows on the right hand side the number of days of completion required for "planning" graphically with a Gantt chart.

Sixth, referring to fig. 7, a mesh is generated and EBS is bound. And generating a grid space according to the information such as the name, the size and the like of the elevation axis grid of the BIM model, binding the grid space with nodes of the EBS 'floor' attribute, indicating the space division condition of the floor, and corresponding to each grid in the grid space.

Seventh, referring to FIG. 8, the EBS end node binds a grid space specification grid. After the binding procedure of the attribute nodes of the EBS sub-division engineering, the corresponding procedure is inherited by the end nodes, and when the space of the end node binding grid is assigned to the grid, the corresponding procedure is inherited by the grid. The grid space can dynamically display the process completion conditions of different areas through the color attribute of the process, and the completion percentage of the corresponding EBS end nodes is reversely deduced, so that the project progress completion proportion is deduced.
