Blocking of factorial experiments in galvanized wire zinc weight test

Industrial competitivity has been, in last years, the business stress aggravated by the strong advance of globalization, with huge effects in commercial world. The run for lower operational costs and for the resources optimization forces the serious organizations to use statistical methods to guarantee the most different development and improvement projects in its processes, for the effect of an error in these areas can lead to significant losses of company image, revenue and market share. The objective of this paper is to contextualize the factorial experiments with blocking method in industrial applications, giving practical examples for method applications and, with a real example, to apply the blocking tool in order to evidentiate its benefits.
