Examples
Referring to fig. 1, fig. 1 is a flow chart illustrating a method for reversely generating WBS structures and engineering cost summaries according to an embodiment of the present application. Wherein the method is performed by a smart device such as a PC.
As shown in fig. 1, the method at least comprises the following steps:
s101: acquiring a history engineering file; wherein, the history engineering file comprises a cost list, and the data in the cost list comprises WBS codes;
specifically, the cost list, i.e., the engineering quantity list, generally includes information such as list codes, engineering names, units, numbers, unit prices, and price, in addition to WBS codes, as shown in fig. 2.
The WBS (Work Breakdown Structure, work decomposition structure) codes are codes set for different projects (or project combinations) in the WBS tree structure constructed in the engineering design process and are used for distinguishing different projects. Table 1 below illustrates a WBS structure.
TABLE 1 WBS Structure
In addition, in a specific application, the history engineering file can be acquired by a file import mode.
S102: sequentially selecting WBS codes from the cost list, and determining node codes of related levels corresponding to the selected WBS codes based on preset standard coding rules;
specifically, the standard encoding rule is a WBS encoding method configured in advance according to actual needs, for example, WBS encoding of different levels and corresponding names can be included in the WBS encoding rule, that is, the WBS encoding can be divided into N levels, so that the level characteristics are reflected, and the WBS encoding method is convenient to view and understand. The method for dividing different levels comprises the following steps:
coding mode one: dividing according to the number of coding bits, such as shown in the following table 3, wherein the first two bits XX represent one stage, the third four bits represent one stage, and the last bit represents one stage;
alternatively, coding scheme two: the partitioning is based on separators, such as shown in table 3 below, with one separator "-" representing a level.
Table 3 two different coding schemes
Of course, other encoding methods may be included, as long as the hierarchical characteristics can be represented, and this is not limited.
After WBS codes are selected from the cost list, the belonging level can be determined according to the corresponding standard coding rules, and then the codes of other nodes of the related level can be determined.
Further, in the specific implementation, step S102: sequentially selecting WBS codes from the cost list, and determining node codes of related levels corresponding to the selected WBS codes based on a preset standard coding rule, wherein the method specifically comprises the following steps: and sequentially selecting WBS codes of the bottom child nodes from the cost list, and determining the WBS codes of the father nodes corresponding to the WBS codes of the selected bottom child nodes step by step based on a preset standard coding rule.
That is, when selecting one WBS code, the WBS code of the bottom child node may be preferentially selected, and then the node code of the higher level (i.e. the parent node code) is obtained step by step according to the WBS code of the bottom child node, for example, the following is illustrated in combination with table 1 and coding mode one: firstly selecting WBS codes of a bottom sub-node, and supposing to select XX063; according to the coding rule, the higher level node thereof, that is, XX060, can be obtained, and according to XX060, the higher level node thereof, that is, XX000, and the lower level nodes XX061, XX062, and the like can be obtained. The arrangement is more beneficial to ensuring that the problem of missing WBS codes in the selection process does not occur.
This step is ended when the sequentially selected WBS codes ensure that all WBS codes in the cost list are selected.
S103: traversing a preset standard WBS structure library based on the determined node codes to obtain corresponding node information;
specifically, a preset standard WBS structure library stores a plurality of standard WBS structures suitable for different projects, each standard WBS structure includes node information, and then the corresponding standard WBS structure and node information corresponding to each node code can be determined from the standard WBS structure library according to the node codes determined in the previous steps. The obtained node information may include, for example, a name and a hierarchy to which the WBS code corresponds.
S104: based on the obtained node information, reversely generating a WBS structure and establishing a corresponding relation with the cost list;
specifically, after node information corresponding to all WBS codes in the cost list is obtained, the WBS structure can be reversely constructed, that is, a tree structure similar to fig. 1 including WBS hierarchy, WBS codes and WBS names is generated, and then the corresponding relationship between the WBS structure and the cost list is built according to the WBS code information.
In some embodiments, the step of establishing a correspondence between WBS structures and cost listings specifically includes: and according to the name corresponding to the WBS code and the hierarchy, mounting the corresponding data in the cost list under the corresponding sub-nodes. Namely, corresponding list data is automatically collected under the WBS structure according to WBS codes in the cost list. Wherein, fig. 3 shows a schematic diagram of the correspondence between WBS structure and cost list. In fig. 3, the left data is a reverse generated WBS structure, and the right is a cost list downloaded by WBS nodes.
S105: and summarizing the engineering cost according to the corresponding relation between the reverse generated WBS structure and the cost list.
Specifically, according to the corresponding relation between the WBS structure and the cost list which are reversely generated in the steps, the engineering cost summarization can be realized, and specifically, the construction cost, the equipment cost and the installation cost are summarized according to different hierarchical relations according to the WBS structure which is reversely generated. The summary results are shown in FIG. 4. In addition, after the summarized results are obtained, the summarized table can be output according to the summarized results of the engineering cost for the user to check.
In the technical scheme provided by the embodiment of the application, the WBS codes are sequentially selected from the manufacturing cost list by acquiring the historical engineering file, and node codes of relevant levels corresponding to the selected WBS codes are determined based on standard coding rules; and traversing a preset standard WBS structure library based on the determined node codes to obtain corresponding node information, further reversely generating the WBS structure, establishing a corresponding relation with the cost list, and finally summarizing the engineering cost according to the corresponding relation between the reversely generated WBS structure and the cost list. The method can reversely generate the WBS structure tree from the engineering cost list detail based on the standard WBS structure and the WBS code, and automatically collect the corresponding engineering cost list under the WBS nodes, thereby realizing forward summarization of various expenses of the WBS nodes, and greatly helping to guide the construction of new project engineering cost and the standard analysis of similar projects based on the WBS structure.
