Accurate prediction of long‐term and short‐term clean energy production is the basis for understanding short‐term clean energy supply capacity, long‐term clean energy development trend and evaluating the effect of energy policies. However, under the circumstances of the large time span, the insufficient data samples and the periodic characteristics of seasonal clean energy production make the traditional...
In order to improve prediction accuracy of traffic accidents, an optimization GM (1, 1) power model is put forward based on the characteristics of S-type and a single traffic accident peak. Specifically, an intelligent optimization method is proposed to optimist the parameter α using PSO algorithm and the optimization formula of background value in GM (1, 1) power model is given based on the integral...
For the evaluation problem of circular economy development efficiency, we take the labour, resources and capital as input elements of circular economy development and take economic growth, social development; industrial “three wastes” discharge treatment compliance rate and the comprehensive utilizat ion rate as output to construct the efficiency evaluation index system of circula r economy development...
