QD Information Services offers custom experimental designs to fit your situation. No matter what your needs, QDIS can provide a design for you based on the factors and variables you want to study as well as taking into consideration any experimental constraints. These designs are computer generated and are setup in order to give you the greatest confidence in the results results. DOE gives you the ability to know for sure if you are it the optimal settings for your process.
With the typical approach to experiments, you may spend a lot of time finding an acceptable result and you still don't know for certain if you are at the optimal conditions. With DOE, you know what the best results are within the range of the variables you studied and will also obtain information on what further experimentation may useful to obain even better results..
Design of Experiments is the use of a carefully selected group of experiments chosen to give the most information with the fewest number of experiments. While not well know, the technique has been around for many years. It is just now becoming popular as is a great tool for optimizing any process. If you need to maximize or minimize some measurement then DOE can help you. Not only do you get the most information from the fewest experiments, but you also generate a model which allows you to predict results at other areas within your experimental space.
