Software Quality Evaluation Model of Smart Electricity Meters Based on CMMI

With the development of the smart grid, the smart electricity meters are gradually developing towards the direction of intelligence and multi-functionality, which places higher requirements on the quality of embedded software. In view of this characteristic of smart electricity meters, the Capability Maturity Model Integration(CMMI) mechanism is introduced, the analytic hierarchy process(AHP) is studied, and the application of the quantitative analysis technology above in the quality evaluation of smart electricity meters software is studied by statistical process principle. The same functions of smart electricity meters from different manufacturers are compared to obtain the weight of each type of function, and the quality of the smart electricity meters software is evaluated based on the weight. The method proposed in this paper can evaluate the quality of smart electricity meters software with uniform specifications from different manufacturers.
