多元系统马氏田口方法的诊断与分析研究

A Study on the Multivariate System Diagnosis and Analysis Using Mahalanobis-Taghchi System

马氏田口方法是研究多元系统的一种新方法,主要用于建立和优化多元系统的测量表,以便采用优化后的测量表进行诊断/预测。本文基于马氏田口方法四大基本步骤和MYT正交分解对马氏田口方法进行了拓展研究。首先,介绍了马氏田口方法的四大基本步骤;接着介绍了MYT正交分解法,并将MYT正交分解法应用于多元系统的马氏田口方法异常值潜在原因分析;最后,利用拓展后的马氏田口方法对某医院血粘度诊断系统进行了优化,同时对利用优化后的测量表进行诊断时发现的异常值进行了潜在原因分析,取得了良好的效果。

Mahalanobis -Taguchi System （MYS） is a new method for studying multidimensional systems. A multidi- mensional measurement scale is constructed and optimized, and it can be used to diagnose or forecast multidimensional systems. MTS is studied in deeper level based on four basic steps of MTS and MYT orthogonal decomposition. Firstly, the four basic steps of MTS are introduced. Secondly, MYT orthogonal decomposition is presented and applied to potential causes analysis of abnormal observations of MTS. Finally, a hospital viscosity of plasma diagnostic system is optimized by MTS and potential causes of one abnormal observation are analyzed, and a good result is obtained.
