〗随着CNG加气站网络建设规模的扩展，必然使得CNG加气机的保有量不断增加。鉴于市场上CNG加气机产品众多，质量参差不齐，导致CNG加气站时有事故发生，危害极大，因而建立一套“标准、简要、适用、可操作性强”的加气机技术水平评价指标体系及评价标准已是当务之急。为此，以国产加气机生产运行现状为切入点，从技术性、安全性、可靠性、经济性等方面出发，建立了国产CNG加气机技术水平评价指标体系层次模型。在实地调研、查阅标准文献、咨询专家的基础上，进行了指标测度。通过模型分解，采用专家打分法和功效函数法对定性指标和定量指标确定分值，建立了加气机技术水平评价标准。由此确立的评价指标体系和评价标准适合于进行计算机辅助评价，可实现加气站设备技术水平异时异地评价，保证了评价结果的客观公正性。

EVALUATION INDEXES SYSTEM OF TECHNICAL LEVEL FOR CNG DISPENSERS 1)

As the network of CNG filling stations expands, the amount of CNG dispensers will increase continuously. Since the brands are many and the quality is not consistent for the CNG dispensers in the market, the accidents happen from time to time in CNG filling stations, which bring large loss. So it is very urgent to establish the evaluation indexes criterions of technical level with the characteristics of standard, simplicity, applicability and easy operation for CNG dispensers. According to the current status of manufacture and operation of china-mode CNG dispensers, with the considerations on techniques, security, reliability and economy, the level model of the evaluation index system is developed. Based on field survey, looking through standard literatures, consulting with experts, the indexes are measured. With model analysis, experts marking and effect function method, the weights of the qualitative and quantitative indexes are determined and the evaluation standard of technical level is set up for CNG dispensers. The evaluation index system and standard is applicable for computer-assisted evaluation, which can be used to evaluate the technical level of equipment for a CNG filling station at other time and place, and guarantee the objectivity and fairness of the evaluation.
