基于层次分析法和群体决策的智能电能表可靠性分配技术研究

针对电能计量设备研发过程中可靠性分配开展的实际情况,以及层次分析可靠性分配方法主观性过强的问题,文中将群体决策引入到层次分析法中,应用于电能计量设备的可靠性分配.聘请多位领域专家分别对智能电能表的递进层次结构模型建立判断矩阵,利用一致性比例构建专家权重,并由指标权重和专家权重形成综合权重,从而克服层次分析法中主观性过强的局限性.通过对某型号智能电能表采用层次分析法和群体决策进行可靠性分配,对基于该可靠性分配结果的设计方案进行可靠性预计评估,其结果证明了方法的正确性和有效性,对于智能电能表在研发过程中的可靠性设计、降低设计可靠性成本、寿命试验(加速、高加速)、实际使用过程的运行维护具有参考价值.

Research on Reliability Allocation Technology of the Smart Meter Based on Analytic Hierarchy Process and Group Decision

Aiming at the actual situation of reliability allocation during the research and development process of electric energy measuring equipment, this paper introduces a smart meter reliability allocation design method based on analytic hierarchy process and group decision. The failure rate tandem model of component stress method and tomographic analysis and group decision-making algorithm are adopted. For components that do not meet the relevant standard failure rate, tomographic analysis and group decision-making algorithm are used. The comprehensive weight of the device is obtained by constructing, comparing and judging the matrix. The failure rate of the design unit is obtained through the failure rate tandem model of component stress method, and then the reliability allocation design of each unit of the smart meter is designed using the series model, which improves the reliability of smart meter to a certain extent. This method has certain reference value for improving the convenience of smart meter reliability design, reducing the reliability cost of smart meter design, the life test (acceleration, high acceleration) of smart meter, and the operation and maintenance of actual use process.
