Principles of robust design methodology

QUALITY AND RELIABILITY ENGINEERING INTERNATIONAL, Issue 1 2008

Abstract The literature on robust design has focused chiefly on the development of methods for identifying robust design solutions. In this paper we present a literature review of conflicts and agreements on the principles of robust design. Through this review four central principles of robust design are identified: awareness of variation, insensitivity to noise factors, application of various methods, and application in all stages of a design process. These principles are comprised into the following definition of robust design methodology: Robust design methodology means systematic efforts to achieve insensitivity to noise factors. These efforts are founded on an awareness of variation and can be applied in all stages of product design. Copyright © 2007 John Wiley & Sons, Ltd. [source]

Robust design of communication systems: The case of expedited forwarding of voice traffic in differentiated services networks

INTERNATIONAL JOURNAL OF COMMUNICATION SYSTEMS, Issue 10 2007

Abstract Design of experiments (DOE) is gaining acceptance in the community of telecommunication researchers, especially during the past several years. In this paper, a state-of-the-art review on the use of DOE in the field of communication networks is presented, and the need for introducing a systematic robust design methodology to network simulations or testbed experiments is identified in ensuring robust behaviours of a network against uncontrollable sources of variation. Then, the Taguchi robust design methodology is applied for optimizing the expedited forwarding (EF) of voice traffic in a differentiated services network, and its step-by-step procedures are described in detail. The experimental data are collected using the ns-2 simulator, and the SN ratio, a robustness measure, is analysed to determine an optimal design condition for each performance characteristic. The analysis results show that ,type of queue scheduling schemes' is a major control factor for ensuring robust behaviours of one-way delay and jitter while ,EF queue size' is for throughput and loss rate. Finally, a compromised optimal design condition is identified using a desirability function approach adapted to multi-characteristic robust design problems. Copyright © 2007 John Wiley & Sons, Ltd.
