Will customer always use our products under optimal conditions? Will our products always be manufactured under optimal conditions? The answer to these two questions is no. The challenge is simply that variation exists everywhere and inherent in all products and processes. Products and or processes which are sensitive to the effects of variation are significant contributors to quality, reliability and ultimately customer dissatisfaction. How can we make our product and or process insensitive to the variation? In this seminar, we will introduce robustness thinking about “how product or process can be designed to insensitive to variation and uncertainty” to explore the synergy between robust engineering and design for reliability. The major focus of this seminar is to achieve reliability improvement through robust design. It does so by factoring reliability into the development of the design itself by designing for target reliability. The result of this approach avoids costly over-design and or dangerous under-design. Recognizing how variation in the environment (e.g., energy source, raw materials, heat, humidity, shock, vibration, dirt and dust) and system internal wear out, deterioration degrade reliability, robust design offers an exciting and effective way to build quality and reliability into products and services versus testing to inspect quality to assure reliability. 演讲摘要 客户会永远在最佳条件下使用我们的产品吗?我们的产品会始终在最佳条件下进行生产吗?这两个问题的回答是否定的。这种挑战其实简单,它就是一切的产品和工艺都受到无处不在固有变异的影响。对不可控的使用环境和变异敏感的产品或过程会对质量,可靠性和最终客户的满意度有着显著的影响。 怎样才能使我们的产品和或过程对不可控的使环境和变异不敏感?在本次研讨会中,我们将介绍建壮性思考“怎样才能使产品或过程设计成对不可控的使环境和变异不敏感”,探索稳健工程和可靠性设计之间的协同作用。 大多数的可靠性问题都与变异和不确定性有关。因此对可靠性的设计,需要直接解决变异和不确定性,而不是间接地利用现场故障率解决问题,这种现场故障往往是质量问题。本次研讨会的主要重点是通过建壮设计,实现低成本可靠性的真正提高。通过可靠性要求的分解融入到产品和过程设计本身的开发,达到以可靠性为目标的设计。这种做法的结果是避免了昂贵的过度设计和或欠缺设计的危险。认识到可靠性如何受变化的环境(如能源,原材料,温度和湿度,冲击,振动,灰尘)导至内部的恶化而降低,相对于以测试去检验确保可靠性的传统方法, 建壮设计提供了一个令人兴奋的和有效的方法通过植入建壮设计来建立产品和服务的质量和可靠性。 本次研讨会还包括: • 可靠性设计(DFR)过程和工具 • 低成本的早期建壮可靠性设计。 • 基于建壮设计的可靠性设计有助于降低产品和服务对不可控的使用环境和变异敏感度,降低产品 开发风险。 减少成本。 • 基本和常见的DFR任务 • DFR记分卡的实施
