Statistical Optimization Of Quality Improvement By Taguchi Methods: Statistics And Quality Control

The aim of this book, Design of a good information system based on several characteristics is an important requirement for successfully carrying out any decision making activity. In many cases although a significant amount of information is available, we fail to use information in a meaningful way .As we require high quality products in day –to –day life ,it is also necessary to have high quality information systems to make robust decisions or predictions . Usually, the required information is to be extracted from many variables (characteristics) that define a multidimensional system . A multidimensional system could be an inspection system or a medical diagnosis system and it is important to have a measurement scale by which the degree of abnormality (severity) can be measured .In case of inspection system the degree of abnormality refers to the level of acceptance of a product and in medical diagnosis.
