摘要
本文基于数值模拟原理,运用模拟相关分析方法解决了管线造价的曲线拟合问题.经实例计算表明,常规的作图和相关分析法、解析和相关分析法均非有效估值,相比之下模拟相关分析的参数估计结果精度最高.
Analog regression method is suggested in this paper based on the theory of digital analogy in order to solve the curve fitting of the pipe cost. The results of calculation example show that the suggested method is more accurate than two traditional methods: diagram regression method and analysis regression method.
