电网企业指标数据溯源模型研究与设计

Research and design of index data provenance model for power grid enterprises

为解决企业信息化环境下,因复杂、冗长的计算加工过程以及计算数据元的质量问题对指标准确性和可信度所造成的不良影响,本文在对数据溯源领域相关技术和模型进行研究的基础之上,分析了指标数据的溯源过程;并结合贵州电网公司指标管理与数据认责管理的实际,通过对W7模型进行扩展,设计了针对指标数据溯源的内容.模型,对溯源过程所需记录的信息内容进行了完整而规范的定义;以OPM模型为蓝本,结合指标数据溯源场景的特点设计了一种轻量化的指标数据溯源表达模型,以执行者、计算过程、工件等三个实体对象为核心,通过四种主要关系对指标的计算过程进行了抽象化的表达;以此为指导设计和开发指标数据溯源管理系统并初步应用,提升指标计算过程的透明度以及结果的可信度提供指导。

In order to solve the problem of the accuracy and credibility of the indexes caused by the complex and lengthy calculation process and the quality of the calculation data element in the enterprise information environment.Based on the research of related technologies and models in the field of data provenance,this paper analyzes the provenance process of index data,designs a content model for the provenance of index data in combination with the actual situation of index management and data accountability management of Guizhou Power Grid Co.,Ltd.By extending the W7 model,a content model for index data traceability is designed,and a complete and standard definition of the information content needed to be recorded in the traceability process is given.According to the OPM model with the characteristics of index data tracing scene,a lightweight representation model of index data tracing is designed,which takes three entity objects as the core:executor,computation process,workpiece,etc.The calculation process of the index is abstractly expressed through four main relations,which is used as a guide to design and develop the index data traceability management system and its preliminary application,improve the transparency of the indicator calculation process and provide guidance on the credibility of the results.
