Abstract

Last year we presented a paper on Design for Reliability (DFR), reviewing the benefits of a good DFR program and included some of the essential building blocks of DFR along with pointing out some erroneous practices that people today are using today. We discussed a good DFR Program having the following attributes: 1.Setting Goals at the beginning of the program and then developing a plan to meet the goals. 2.Having the reliability goals being driven by the design team with the reliability team acting as mentors. 3.Providing metrics so that you have checkpoints on where you are against your goals. 4.Writing a Reliability Plan (not only a test plan) to drive your program. A good DFR Program must choose the best tools from each area of the product life cycle: identify, design, analyze, verify, validate, monitor and control. The DFR Program must then integrate the tools together effectively.effectively. Since then, we have developed a method to calculate the Return on Investment (ROI) from a Design for Reliability (DFR) program, also known as the DFR ROI. In this paper, we will discuss a method we have developed to calculate the Return on Investment (ROI) from a Design for Reliability (DFR) program, also known as the DFR ROI. There are a number of factors involved in calculating the ROI for your DFR program, including: 1) improved warranty rate (derived from your reliability maturity level) 2) current warranty rate 3) cost per repair 4) cost of new reliability program 5) savings from losing a customer 6) volume. In this paper, we will show you how to calculate each of these to derive your DFR ROI.
可靠性设计项目的投资回报
去年,我们发表了一篇关于可靠性设计(DFR)的论文,回顾了一个好的DFR程序的好处,包括DFR的一些基本构建模块,并指出了今天人们正在使用的一些错误做法。我们讨论了一个好的DFR程序具有以下属性:在项目开始时设定目标,然后制定实现目标的计划。2.可靠性目标由设计团队驱动,可靠性团队作为导师。3.提供度量标准,这样您就可以检查自己离目标还有多远。4.编写一个可靠性计划(不仅仅是一个测试计划)来驱动您的程序。一个好的DFR程序必须从产品生命周期的每个领域选择最好的工具:识别、设计、分析、验证、验证、监控和控制。DFR项目必须有效地将这些工具整合在一起。从那时起,我们开发了一种方法来计算投资回报率(ROI)从可靠性设计(DFR)程序,也被称为DFR投资回报率。在本文中,我们将讨论我们开发的从可靠性设计(DFR)程序计算投资回报率(ROI)的方法,也称为DFR ROI。在计算DFR项目的投资回报率时,有很多因素,包括:1)提高的保修率(来自于你的可靠性成熟度水平)2)当前的保修率3)每次维修的成本4)新可靠性项目的成本5)因失去客户而节省的成本6)销量。在本文中,我们将向您展示如何计算这些,以获得您的DFR ROI。
