Keywords: Design for Variation ; Uncertainty Analysis ; Engineering Design ; Automated Design ; Culture Change ; Sensitivity Analysis
Abstract:

We will illustrate our use of Design For Variation, a statistical engineering initiative, to solve the challenge faced by many engineers today: to design physical parts and systems that will meet requirements, to address the various sources of uncertainty and variability that accompany the design process, and to do this in less than half the time of previous design processes. Our solution to this challenge has enabled us to improve both the fidelity and the speed of the design process. In turn, however, this solution has introduced new challenges. These include the challenges of providing engineers with a "toolbox" of robust, user-friendly statistical methods and software that integrate with engineering design and analysis tools and then training a large population of non-statisticians in these methods and tools. We will also discuss the challenges of communicating this new approach and our success with it across the company and then into the broader aerospace industry. Lastly, we will discuss the challenges in driving culture change across the business and into the industry to accept use of these new tools and methods as a best practice for the future.
