摘要
运用层次分析法建立起燃气供销差的AHP结构模型,通过判断矩阵求出影响供销差各个因素的权值,按照权值的大小对其进行了排序,识别出燃气表的示值误差、计量的工况不同和流量计选型不当是影响燃气供销差的关键因素,最后针对性地提出4项控制措施来降低燃气的供销差。
In this paper,AHP structure model of gas supply and market balance is built up based on the analytic hierarchy process.The weights of different factors influencing supply and market balance are figured out from the judgment of matrix,and factors are sorted out according the degree of weights.Then it is identified that gas meter indication error,difference of measuring conditions,and improper selection of flow meters are the key factors affecting the gas balance.At last,four controlling methods are put forward according the above study so as to reduce gas supply and market difference.
