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.
