垂直管流压降梯度算法优选综合评判模型中权向量的确定

Calculating weight matrix of fuzzy comprehensive evaluation model about method of computation flowing pressure loss in vertical pipe

应用模糊数学方法,选取Orkiszewski等8种相关式、考虑了含水率等7种影响因素建立了垂直管流压降梯度算法优选综合评判模型模型框架。以斯伦贝谢公司的PipSim2003为计算平台,采用正交试验结合方差分析、主成分析的方法,利用方差贡献率可作为评判的权重向量这一观点,经过计算,得到了优选综合评判模型的一个权数矩阵。

With the help of indescribable mathematics,set up a frame of model,fuzzy comprehensive evaluation model about method of computation to flowing pressure loss in vertical pipe. It have 8 correlations（such as Orkiszewski）and 7 affecting factors（such as oil water cut）.Using 3 theories, orthogonal test, analysis of variance, principal constituent, and following such viewpoint what variance contribution rate equal weight,the results are obtained by using pipsim2003 which is a product of Schlumberger.
