MIXTURE DESIGNS FOR Q-COMPONENTS IN ORTHOGONAL BLOCKS

In industrial experimentation designs are needed to estimate the effec ts of mixture components independently of process variables. This pape r gives general methods of constructing designs for q greater-than-or- equal-to 3 mixture components in two or more orthogonal blocks. The de signs are built from Latin squares with specific properties and are ge neralizations of those for four and five components given by Draper an d co-workers and Prescott and co-workers respectively.
