Abstract

This chapter deals with construction of a new design for an experiment that was required for one of the clients, an aluminium alloy foundry in Chennai, India. The experiment was aimed at reducing casting defects. Typically these experiments are carried out using suitable orthogonal arrays as they are most efficient for such experiments. But the experiment required for the study could not be fitted into any of the known orthogonal arrays. This has triggered a quest for finding the most efficient design for the requirement. This quest has lead to construction of a factorial design that is pretty close to an orthogonal array. The ideas for constructing the new design are interesting and the approach could be extended to construction of similar designs for similar requirements. The approach uses integer linear programming formulations for the construction. The main purpose of including this study as a chapter in this book is to highlight the fact that research is an important faculty of a successful consultant.
