For ease of understanding, the related concepts related to the embodiments of the present application will be first described.
Transferring engineering resources: for a fixed asset that has reached a usable state, the power grid enterprise takes it into account and calculates the cost of the asset.
Digital twinning: the digital twin is a simulation process integrating multidisciplinary, multi-physical quantity, multi-scale and multi-probability by fully utilizing data such as a physical model, sensor updating, operation history and the like, and mapping is completed in a virtual space, so that the full life cycle process of corresponding entity equipment is reflected.

BIM technology is a new tool in architecture, engineering and civil engineering. The GIM is a digital model which is in accordance with the GIM specification and is constructed for power grid engineering.
Enterprise Resource Planning (ERP): the ERP in the application refers to an ERP system of a national power grid company, and an engineering management and control module in the ERP is a management system for carrying out power grid engineering.
Power grid engineering: it refers to the work related to the production, transmission and distribution of electric energy, such as building a power network in a place, and the work may include electric wires, poles, transformers, etc.
Work Breakdown Structure (WBS): the method decomposes the construction work of the infrastructure construction of the power grid into small tasks with tree structures.
Materials: the raw material of the production equipment can be, for example, a screw and a nut.
Equipment: devices produced from materials, such as lightning rods, transformers.
Asset: assembled by a plurality of devices.
WBS encoding: for indicating the work step to convert from the material to an asset.
In this embodiment, the method may include, for example, the steps of: S101-S104.
S101: acquiring a corresponding relation of a pre-configured material code, an equipment code, an asset code and a Work Breakdown Structure (WBS) code, wherein the WBS code is used for indicating a work step of converting the material indicated by the material code into the asset indicated by the asset code.
In one example, a project WBS architecture can be selected and built in an ERP system in advance, a power grid project is selected to create a WBS code, and equipment materials are recorded into the ERP system. And establishing a GIM of the power grid project by adopting a digital twinning technology, respectively establishing unique codes for materials, equipment and assets of the power grid project in a GIM model, and establishing a corresponding relation of four codes of 'material coding-equipment coding-asset coding-WBS coding' through the GIM model. In other words, the correspondence relationship may be obtained by the GIM constructed using the digital twinning technique.
In the embodiment of the present application, when it is determined that a certain asset can reach a usable state, an asset code of the asset may be obtained, and then the asset code is used as an index to find the aforementioned "four-code correspondence" including the asset code, so as to transfer the asset by using the "four-code correspondence".
S102: and determining construction cost corresponding to the WBS code according to the WBS code.
In an implementation manner of the embodiment of the present application, according to a predetermined expense allocation rule, construction costs corresponding to respective working steps in the working steps indicated by the WBS code may be determined, so as to obtain the construction costs corresponding to the WBS code. The cost apportionment rule may be predetermined, for example, and is predetermined according to a construction contract.
In yet another implementation, the construction cost corresponding to each construction step may be pre-saved, then the work step indicated by the WBS code is determined, and further the construction cost corresponding to the WBS code is obtained according to the construction cost corresponding to each pre-saved construction step.
S103: and determining the purchasing cost of the material indicated by the material code according to the material code and a purchasing list which comprises the material corresponding to the material code.
In an embodiment of the present application, a department responsible for purchasing may, for example, first enter a purchase list of materials into the value ERP system. Therefore, a purchasing list can be obtained from the ERP system, and the purchasing cost of the material corresponding to the material code in the 'four-code correspondence' can be obtained from the purchasing list.
S104: and obtaining the cost of the assets indicated by the asset codes in the corresponding relation according to the construction cost and the purchasing cost.
For a certain asset, the cost of the asset may include two parts, one part is construction cost, and the other part is procurement cost of materials corresponding to the asset. In view of this, after determining the procurement cost of producing the material of the asset indicated by the asset code and the construction cost of producing the asset corresponding to the asset code, the cost of the asset indicated by the asset code in the corresponding relationship can be obtained according to the construction cost and the procurement cost. In one example, a sum of the construction cost and the procurement cost may be determined as a cost of the asset corresponding to the asset code.
According to the scheme, the assets can be automatically determined by the equipment without manual asset transferring treatment, so that the asset transferring efficiency of the power grid engineering is improved. And compared with the manual resource transferring treatment of the assets, errors caused by human factors are avoided, and the resource transferring accuracy of the power grid project is improved.
