The Design for Trustworthy Software Compilation Taguchi Methods and Optimization for Robust Software

Introduction

Taguchi’s quality loss function provides a measure of the overall loss to society when a product fails to meet its target functionality and reliability. His signal-to-noise ratio measures the positive quality contribution from controllable or design factors versus the negative quality contribution from uncontrollable or noise factors. Taguchi Methods involve seven steps, beginning with a clear statement of the design problem and ending with a confirming statistical experiment showing how parameter choices will enhance robustness. An example from electrical circuit design is presented because it is much more similar to software design than mechanical design, where Taguchi Methods have found their largest application. A more detailed ...
