A New Approach to Reduce Time Consumption of Data Quality Assessment in the Field of Energy Consumption

This paper is devoted to solving the problem of reducing the time costs of the process of data quality assessment. The data describe energy resources consumption of various enterprises and institutions. The first part of the paper contains a review of recent data quality assessment studies was made. The analysis describes the problems of this process and the characteristics of the data, metadata and the algorithms used in it. The next part of the paper shows a new approach to reduce the time consumption of the process of assessing the data quality, which differs from the existing ones by the presence of a data-packaging and decision-making support using the oDMN+ notation. Finally, this paper presents an implementation example of the oDMN+ model for data on the energy consumption of the Volgograd hardware plant. The results showed that the use of data packaging and modeling the assessment process is a promising approach for modeling and reducing time costs in the process of data quality assessment for energy management systems used in the enterprises and institutions.
