A modeling framework is presented that aims to estimate the reliability of a variant design throughout the product lifecycle to support reliability enhancement decision-making. A Bayesian approach to modeling is adopted where expert judgement data is combined with in-service reliability data. This paper reports one practical implementation within an ongoing electronic design project. A formal process of evaluation is embedded within the modeling process to capture the views of relevant engineers, managers and analysts during the implementation. Through this evaluation we share our experiences in the successes and challenges of modeling, and offer guidance on pitfalls to avoid. The major challenge has been managing the change in reliability culture within the design team required to make this process work. Other problems relate to the acquisition of relevant, good quality data in a timely and cost-effective manner. The major successes relate to getting engineers together to think about reliability issues and share experiences. The modeling process is novel to the engineers, but has encouraged them to review the impact of their decisions on reliability and draw more useful information from the reliability indicators provided by the model.","PeriodicalId":395613,"journal":{"name":"Annual Reliability and Maintainability Symposium. 2002 Proceedings (Cat.

They caution about the use of the exponential distribution to represent component repairs and the failure of many to appreciate the implications of the exponential distribution's memory-less property. In summary, this paper provides insight into the good aspects of using the exponential distribution but more importantly, into the ubiquitous misuse of the most commonly implemented reliability distribution.","PeriodicalId":395613,"journal":{"name":"Annual Reliability and Maintainability Symposium. 2002 Proceedings (Cat.

The object of this approach is to derive qualitative and quantitative safety integrity requirements for technological systems. The framework is holistic and covers technological as well as human and operational factors. The framework is compared to other approaches. Three different railroad signaling case studies, that use the same process, but under different circumstances, are presented. The lessons learned from these case studies, which, like the process itself have applications beyond railroad signaling, are reported and discussed.","PeriodicalId":395613,"journal":{"name":"Annual Reliability and Maintainability Symposium. 2002 Proceedings (Cat.

Additionally, the authors present the concept of importance, which allows to determine the influence of a component failure on the system failure. In a case study, the three steps for the system reliability analysis of a single-step gearing are shown. It is demonstrated how to receive the reliability function of components from failure data or from calculations respectively. Within the calculation, the B/sub 10/ lifetime is determined by means of the damage accumulation hypothesis, especially for the pinion, the gear and the ball bearings. Afterwards a database is used to determine the parameters of the three-parameter Weibull distribution. As a result, the authors received the system reliability of an analyzed gearing. The reliability tool SYSLEB was used for the evaluation of the failure data of the radial shaft seals. Additionally, the reliability functions for the components as well as for the system were determined by applying SYSLEB. It was shown that the system reliability could be increased by improving the pinion and the gear to avoid breakage. For this purpose preventive maintenance actions could also be applied.","PeriodicalId":395613,"journal":{"name":"Annual Reliability and Maintainability Symposium. 2002 Proceedings (Cat.
