Resumo
This work describes the design of experiments and response surface methodology (RSM) via
factorial designs programmed in PlanEx, a new web/online software implemented using the
Java language. The goal was to develop and validate PlanEx as a simple, efficient, and an
interactive tool for undergraduate teaching and research. PlanEx was also designed as a free
software, and the Java language was chosen since it is a community-developed open source
software. PlanEx provides both full factorial design of experiments (2k) and fractional (2k-1),
with up to six variables, and with, or without, replicates. PlanEx was also developed to
perform variable screening through replicates, and normal probability plots and also to
evaluate the model bias by the residual graphs. PlanEx is based on RSM with up to four
variables at three levels, and central points with, or without, replicates. Through RSM the user
can check linear or quadratic models to predict experimental responses through 3D surface
plots, and analysis of variance (ANOVA). PlanEx was also evaluated in the second term of
2009, 2010, and 2011 in graduate courses of planning and design of experiments. The results
have shown that PlanEx is fast, and interactive, and it is a simple design of experiment tool
for both teaching and research.
