Construction of the Indicator System Applied to Evaluate Basic Capabilities of Smart Meter Enterprises on NQI

Abstract

In order to quantitatively evaluate the basic capabilities of smart meter enterprises on National Quality Infrastructure (NQI) and continuously improve the quality level of smart meter enterprises, this paper, profited from China’s NQI capability index system and the Delphi method, with representiveness of indicators as the starting point, and based on repeated screening and expert demonstration, chooses the most representative indicators devised for NQI factors such as measurement, standardization, certification & accreditation, inspection & testing and quality management in the production of smart meters, and constructs an indicator system applied to evaluate the basic capabilities of smart meter enterprises on NQI, which includes 5 first-level indicators, 8 second-level indicators and 30 basic indicators. With construction of this system, we can quantitatively evaluate the basic quality and technology capabilities of smart meter manufacturers and continuously improve deficiencies of enterprises on their NQI. And, the State Grid can also apply this system as a technical specification to evaluate the quality level of smart meter enterprises.
