There are so many factors involved that can make or break a company in this fast paced world where companies have to aggressively meet new demands, especially from the customers because they are the ultimate evaluator of the company's product. One therefore needs a way to integrate 'customer voices' in this costly production process as it is essential for the component manufacturers and vendors to know precisely what their customer wants and expects in a device so that they can meet their needs. With the application on the power rectifier, this work illustrates how QFD can help the power device vendors and manufacturers to achieve greater customer satisfaction through supplying a better quality and more reliable product. The completed functional QFD matrix allows the manufacturer to identify the most critical need from the customer that corresponded to the key technical requirements. This helps the manufacturer to focus its attention on the more important customer needs. The completed reliability QFD matrix together with the FMECA analysis helps the manufacturer to consider the reliability demands from its customer. Integrating both the QFD and FMECA charts helps to identify the most critical failure modes and its associated failure mechanisms. Finally, a spreadsheet implementation to generate the QFD and FMECA matrices have been created to reduce the cumbersome process of the numerous manual recordings.","PeriodicalId":395613,"journal":{"name":"Annual Reliability and Maintainability Symposium. 2002 Proceedings (Cat.

Most of the reliability models consider failure time as the only factor that influence reliability characteristics of a system during its operation. It is possible to include the effect of operating conditions like type of failure, stress etc. in the reliability function. These conditions when quantified are called covariates and the model is known as proportional hazard model (PHM). The proportionality of hazard rates at different covariates is the underlying assumption. Two types of failure data are studied; renewal process data and non-renewal process data. Different methods of estimation of cumulative hazard rate (CHR) function are discussed under nonparametric and parametric models. Goodness of fit tests are used to verify the assumption of PH model. Parametric models like Weibull distribution or power law process are fitted to check the results obtained using nonparametric models. The parameters of life distributions are obtained by regressing the reliability function using multiple regression analysis or by maximum likelihood estimators (MLEs). The study involves failure data of an electro-mechanical equipment in all underground coal mine and failure times of a small DC motor in accelerated life testing using PHM techniques to assess their failure behavior at different operating conditions. The study also involves evaluation of optimum preventive maintenance interval in a thermal power unit based on graphical methods using PH models.","PeriodicalId":395613,"journal":{"name":"Annual Reliability and Maintainability Symposium. 2002 Proceedings (Cat.

In the current government acquisition environment great emphasis is being placed on innovative contracting approaches that involve cooperative agreements, performance-based contracting, and contractor use of best practices. Thus, far fewer prescribed standards and specifications are involved in government acquisition today as compared to the early 1990s. Additionally, the shift from rule-based assurance management to knowledge-based approaches poses a separate set of challenges as clearly underscored in government and industry accident assessments and mishap investigations that followed a costly streak of launch vehicle and spacecraft failures in the late 1990 time frame. In response to these challenges the NASA Office of Safety & Mission Assurance began development of the Process Based Mission Assurance Knowledge Management System (PBMA-KMS) in mid 1999. The PBMA-KMS is a user-friendly, web-based system designed to support life-cycle safety and mission success management. This paper describes the PBMA-KMS functionality, operation, and plans for future growth. Aerospace professionals are encouraged to use the PBMA-KMS by participating in discipline oriented work groups, and contributing best practices, lessons learned, and ideas for future functional enhancements.","PeriodicalId":395613,"journal":{"name":"Annual Reliability and Maintainability Symposium. 2002 Proceedings (Cat.

This paper describes some innovative approaches for transforming each measurement into a dimensionless quality index, so that these quality indices can be rolled up to obtain an overall quality indicator for a specific product. An example is given to illustrate how the proposed roll up would be done to obtain an overall quality indicator for specific products. The approach described in this paper can be applied by a supplier of telecommunications products to transform the measurements for any product into individual quality indices and then rolled up into an overall quality indicator for comparison with the industry average and the industry best. The results of such industry comparisons can then be used by the supplier for identifying the gap with the best performer (if this product is performing below the industry best), developing a plan for continuous improvement, and for closing the gap with the best performer.","PeriodicalId":395613,"journal":{"name":"Annual Reliability and Maintainability Symposium. 2002 Proceedings (Cat.
