正交实验设计法在工业生产中具有广阔的应用领域,但由于推广不够,在实践中还不为大多数工业企业,尤其是中小企业所接受,除了观念上的影响外,对操作方法的疑惑和不熟悉,也是重要因素。为解决此类问题,文章选取了两个典型案例,对正交实验设计法的操作方法和步骤进行了介绍,以起到引导和示范作用。 Orthogonal experimental design method in the industrial production has a wide range of applications, but because of inadequate promotion, in practice, not for most industrial enterprises, especially small and medium enterprises to accept, in addition to the concept of the impact of the operational methods of doubt And not familiar with, but also an important factor. In order to solve these problems, this paper selects two typical cases and introduces the operation methods and steps of Orthogonal Experiment Designing Method, in order to play a guiding and demonstration role.
