Design of Experiments

Question 1

The simplest form of a Design of Experiments that enables operators to observe the changes occurring in the output (Y Response,) of a process while changing one input (X Factor).

An example would be to test the cycle time (Y) to cook a pizza in one oven as a result of altering the temperature (X) in that oven.

Answer 1

DOE - One Factor At A Time (aka OFAT)

Question 2

A form of Design of Experiments that enables operators to observe the changes occurring in the output (Y Response,) of a process while changing more than one input (X Factors). This test highlights shifts in the average response or output associated with multiple factors. It also evaluates how factors in a process might interact.

An example would be to test the cycle time (Y) to cook a pizza in different ovens (X1) at different temperatures (X2).

Answer 2

DOE - Full Factorial

Question 3

A form of Design of Experiments that enables operators to observe the changes occurring in the output (Y Response,) of a process while changing more than one input (X Factors) without running every single potential treatment combination. This test highlights shifts in the average response or output associated with multiple factors with less time and effort than required for a full factorial experiment. It has a diminished ability to evaluate how factors in a process might interact.

An example would be to test the cycle time (Y) to cook a pizza in different ovens (X1), at different temperatures (X2), and with different toppings (X3) without running every single combination of the three factors.

Answer 3

DOE - Fractional Factorial
