摘要
调水系统包括众多的建筑物,确定各个建筑物在系统中的权重,对于系统的运行维护、风险评估及分析具有重要的意义。给出最小二乘法意义下的权重求取办法,J不仅反映调水系统中各建筑物整体的比例关系,而且反映出单体建筑物之间的细微差别。通过本算法求出的权重系数既考虑了全局又考虑了局部的细微区别。本算法同样可以适用于单体建筑物不同组成部分权重的求取。
Water transfer system is made up of many different constructions Estimation of weight of the key constructions of water transfer system is a basic work for operation and maintenance of system, risk analysis of system and cost computation of failure. This paper proposed a Nonlinear Least-Squares method to compute the weight of key constructions. The matrix shows not only the overall correlation between individual construction and system but also the detailed difference among individual construction. The proposed method takes into account both overall terms and detailed terms. The proposed method can be applied to compute the weight of different parts of individual construction in transfer system.
