† School of Engineering, Universidad de los Andes, San Carlos de Apoquindo 2200, Santiago, Chile ‡ Computer Science Department, School of Engineering, Pontificia Universidad Católica de Chile, Vicuña Mackenna 4860, Santiago, Chile In the last years, several works have pointed out that products and processes lack quality because of performance inconsistency, often produced by parameters that are...

Testing can be considered an investment. A software organization—whether an in-house IT shop, market-driven shrink-wrap software vendor, or Internet ASP— chooses to forego spending money on new projects or additional features to fund the test team. What’s the return on that investment (ROI)? Cost of quality analysis provides one way to quantify ROI.

Researchers often identify robust design, based on the concept of building quality into products or processes, as one of the most important systems engineering design concepts for quality improvement and process optimization. Traditional robust design principles have often been applied to situations in which the quality characteristics of interest are typically time-insensitive. In pharmaceutic...

The method of robust design has long been used for the design of systems that are insensitive to noises. In this paper it is demonstrated how this approach can be used to obtain a robust eco-design (ecological design). In a case study, robust design principles are applied to the design of a factory smokestack, using the Gaussian Plume Model (GPM). The GPM is a well-known model for describing po...

1 32.3 Taguchi’s Robust Design Method Since 1960, Taguchi methods have been used for improving the quality of Japanese products with great success. During the 1980’s, many companies finally realized that the old methods for ensuring quality were not competitive with the Japanese methods. The old methods for quality assurance relied heavily upon inspecting products as they rolled off the product...

A systematic and affordable approach is proposed for the robust design of thick laminated composite structures. Our approach integrates the principles of the Robust Concept Exploration Method (RCEM) for designing complex engineering systems and the hierarchical multi-level optimization procedure for managing the complexity of composite structure optimization. Foundational to the proposed approa...

in design of experiments, analysis and identifying those variables that affect the outputs are of interest. response surface methodology is a mathematical-statistical method to optimize the experiment outputs. this method tries to find the best response levels by optimizing the design variables called factors. in many engineering applications, robust design has become the most important issues....
