Data modeling method of asset life cycle based on sg-cim model

Abstract

The invention discloses a data modeling method for the full life cycle of assets based on the SG-CIM model, which introduces a physical ID, takes the physical ID as the core, and converts the material code, item code, WBS, asset code generated in the full life cycle management of the asset Card number, equipment code, resource code, and waste material code are correlated to establish a data model for the full life cycle of physical assets, and connect the information of each key link of asset management, so as to complete the full life cycle tracking of physical objects, and integrate the physical logistics and information flow of assets. , value flow, and effectively support the full life cycle management of physical assets.

Description

technical field [0001] The invention relates to the technical field of electric power systems, and more particularly, to a data modeling method for the entire life cycle of assets based on an SG-CIM model. Background technique [0002] Explanation of relevant terms involved in the present invention: [0003] SG-CIM: State Grid Corporation Enterprise Unified Information Model (SG-CIM), which is defined by object-oriented modeling technology and expressed in unified modeling language. is described in the form of 3.0 being its version number. [0004] Physical ID: It is the unique and lifetime identification code of the physical object. It consists of 3-digit company code + 2-digit identification code + 18-digit serial number + 1-digit check code to form a 24-digit decimal device physical identification code. [0005] Item Code: The unique code of the item, used to identify the item. [0006] WBS coding: Work Breakdown Structure (WBS) is a hierarchical structure that subdivi...

Problems solved by technology

[0012] However, due to the long-term asset segment management model and the lack of a unified identity, it is difficult to achieve asset information sharing and data barriers exist, which restricts the further deepening of asset life cycle management

[0013] At present, asset planning and planning information is scattered in the planning and planning system and PMS2.0 system, equipment purchase information is scattered in ECP and ERP systems, project construction information is scattered in infrastructure management system and ERP system, and information such as operation, maintenance and decommissioning is scattered in ERP and PMS2 .0 system, some of the cost items of the asset life cycle cannot be accurately obtained (such as other expenses, failure costs), and some cannot be corresponding to individual assets (such as operating costs), which cannot effectively support the accounting of asset life cycle costs

[0014] Asset life cycle data is scattered in various business links and multiple information systems, and business data standards and business management requirements are not uniform, asset information integration, collection, and analysis are difficult, and the level of information utilization is low

In particular, insufficient data sharing leads to multi-entry, repeated collection of data, and a high proportion of manually input data, insufficient data accuracy and real-time performance, insufficient support for the "three-in-one" life cycle of assets, and extensive cost accounting throughout the life cycle. Lean management cannot be implemented

In addition, in recent years, a large number of new projects have been put into production and operation, and the equipment has been updated quickly, which has caused troubles to the company's entire process of tracking information and data within the asset life cycle.
