Development of the program for searching the optimum condition using design of experiments

Abstract

The Design of Experiments (DOE) is a method that is widely used due to its effectiveness to select optimum conditions in the design stage of product development. On the other hand, a fast, low cost, labor saving and energy-saving innovative development is also required in industry. In this research, a program for quickly searching the optimum condition using design of experiments is developed and evaluated. Relationships between each parameter and the final property are firstly cleared for each formula by using the design of experiments. Then the optimum conditions for each parameter were decided by using these formulas in a program. The optimum final property with each optimum level value were calculated. In addition, the optimum condition for cooling system using alkaline water mist was investigated for evaluating this program in an experiment. It is concluded from the result that (1) the program using the design of experiments was useful for fast development process, (2) this program could quickly and accurately decide the optimum cooling condition for cooling system using alkaline water mist.
