一、正交试验设计推行TQC以来,其他管理技术和质量管理工具中正交试验设计是应用最广泛的方法之一。这不仅是因为在化工生产中需要寻找一种耗费较少的人力财力物力又能进行必要的实验来摸索较优的生产条件的方法,还因为它不需要进行复杂或繁琐的计算,从而受到化工企业广大职工的欢迎。下面就使用中的问题作些说明。首先在一般情况下应选择自变量作为被考察的因素。如果选用因变量,就涉及到两 I. Orthogonal Experimental Design Since the implementation of TQC, orthogonal test design among other management techniques and quality management tools is one of the most widely used methods. This is not only because of the need to find a method that uses less human and financial resources, but also can carry out necessary experiments to explore better production conditions in chemical production, and because it does not require complex or cumbersome calculations and is therefore subject to chemical industry. The majority of employees welcome. The following explains some problems in use. First, in the general case, you should select the independent variable as the investigated factor. If you choose the dependent variable, it involves two
