Robust Engineering

BACKGROUND AND INTRO TO ROBUST ENGINEERING
This chapter provides an introduction to the methodology of Robust Engineering. As Robust Engineering is based on Taguchi Methods , it is important to give an overview of Dr. Genichi Taguchi, some insight into the history of the methods development, definitions of the terminology and a description of the basic procedures.
There are two types of quality:
Type 1: Customer quality (features what customer wants)
Type 2: Engineered quality (problems customer does not want)
Customer quality leads to the size of the market segment. It includes items such as the function itself, features, color and designs. The better the customer quality, the bigger the market size becomes. In order to obtain the market size, the price must be reasonable. Customer quality is addressed during product planning. Robust engineering does not deal with customer quality. Customer quality is extremely important to create a new market.
On the other hand, engineered quality includes defects, failures, noise, vibrations, unwanted phenomena and pollution. Robust engineering is extremely important in winning the bigger market share. While customer quality defines the market size, engineered quality wins the market share within the segment. Robust Engineering deals with engineered quality.
The job of the engineer is to create and develop a system to perform the function required by customer quality. First, several concepts are generated and one or a few concepts go under development. The engineers develop the product so that it performs the intended...
