BENEFITS OF EXPERIMENTAL DESIGN

Experimental Designs (ED) enables industrial engineers to study the effects of several variables affecting the response or output of a certain process. Experimental Designs (ED) methods have wide potential application in the engineering design and development stages. It is the strategy of the management in today's competitive world market to develop products and processes insensitive to various sources of variation using ED. The potential applications of Experimental Designs (ED) in industries are:

• reducing product and process design and development time;
• studying the behaviour of a process over a wide range of operating conditions; minimising the effect of variations in manufacturing conditions;
• understanding the process under study and thereby improving its performance;
• increasing process productivity by reducing scrap, rework etc.;
• improving the process yield and stability of an on-going manufacturing process;
• making products insensitive to environmental variations such as relative humidity, vibration, shock and so on;
• studying the relationship between a set of independent process variables (i.e., process parameters) and the output (i.e., response).
