Abstract The first-class urban distribution network is the key content of our country’s current construction. In order to obtain accurate evaluation results, a first-class urban distribution network evaluation index system is constructed from four aspects of reliability, economy, low carbon and intelligence, and a decision-making method based on cloud model and probability analysis is pro-posed. The cloud model is used to express and process the linguistic evaluation information of qualitative attributes given by experts. The 3En criterion is utilized to convert the cloud model to the interval value, thereby reducing the impact of randomness on distribution network evaluation results. The probability method is used to process the interval value and obtain the comprehensive evaluation results. The proposed method can effectively solve the randomness and fuzziness of qualitative indicators in the evaluation process. Finally, the method is used to evaluate and sort 11 regional distribution networks in xi ‘an jurisdiction, and the effectiveness of the proposed method is demonstrated according to the actual situation.
