Continued Innovation: Pushing the Boundaries of DoE

At Effex, it is our conviction that, when generating experimental designs for its user, we have to take advantage of 21st century technology.

When we are talking about Design of Experiments we all understand the involvement of the statisticians and the scientists or engineers

Of course not the potato chips themselves 😉 but in the production proces of potato chips, DoE is used.

Response Surface Designs (RSDs) are a core component of the response surface method- ology, which is widely used in the context of product and process optimization.

The family of orthogonally minimally aliased response surface or OMARS designs comprises traditional response surface designs, such as central composite designs and Box-Behnken designs, as well as definitive screening de- signs.

After completing the experimental runs of a screening design, the responses under study are analyzed by statistical methods to detect the active effects.

Consumers' trend of reducing the number of calories ingested per day, prompts a known food industry to decide to lower the fat content in our of their main products. In order to achieve this, the recipe of the product needs to be modified. An additional difficulty in the process is the fact that the different ingredients of the product come in batches, and each batch is slightly different from each other in terms of viscosity, particle size and other characteristics. The product quality should be robust against variability in the batches of raw material.

What if, due to new regulations, a product from your chemical company is 𝗻𝗼𝘁 𝗰𝗼𝗺𝗽𝗹𝗶𝗮𝗻𝘁 to more strict specifications imposed by the regulatory agencies?

Orthogonal Minimaly Aliased Response Surface Design for three-level quantitative factors and two-level categorical factors

Omars designs bridge the gap between definitive screening designs and classical response surface designs (such as central composite and Box-Behnken designs)
