This system a) collects field failure data, b) tracks/drives corrective actions, c) pulls the lessons learned from the corrective actions, d) places those lessons learned in the proactive analysis tools used in product development, e) drives product development to use the proactive analysis tools, f) keeps a library of proactive analyses to act as guides for future development, g) provides the proactive analysis for direct use by a root cause team driving to analyze and correct a field failure h) tracks and drives all activities - allowing instant summary \"dashboards\" or \"scorecards\" to be created. proactive and reactive records are stored coincidently in a single database system -- allowing real-time feedback. Reactive case resolution teams can tap into the development analyses or development teams can incorporate all relevant lessons learned from reactive case resolutions. All tools are attached to the database - to drive consistent usage and facilitate the integration of analysis libraries. All activities are mapped to a business process with pre-specified milestones and tracked to target dates - making this a real-time product reliability and safety management tool. Each record instantly becomes an ISO 9001 controlled quality record upon closure. A record tree structure allows cases/records to follow the configuration management of the product. The culmination of these features allows the user community to achieve product safety and reliability business management system over the full life cycle of a product. After two years of implementation and continuous improvement, a fundamental truth is proven. The process will only be sustainable and the database tool will only achieve long term success if the users feel their personal workflow facilitated by the system.","PeriodicalId":270494,"journal":{"name":"Annual Symposium Reliability and Maintainability, 2004 - RAMS","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126475711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Differences in the interpretation of these metrics by designers, project managers and product support engineers within an organization may compromise the effectiveness of any technical or commercial decision-making that is based upon reliability prediction and field return data analysis. The same concern is true for customer and supplier interfaces with the organization, where reliability requirements and contractual guarantees, such as spares provision, are defined. The main issues appear to be related to an inadequate understanding of reliability requirement objectives. The process of negotiating and agreeing to requirements between a supplier and customer appears to be flawed in many cases by a lack of knowledge regarding the assumptions associated with the chosen metric. Holistic approaches to reliability such as REMM (reliability enhancement methodology & modeling) can provide alternative metrics from those traditionally used in the engineering community. This paper outlines the metrics available from such techniques and compares them with the more commonly used engineering metrics such as removal rate, mean time between failure (MTBF) and mean time between removal (MTBR). In conclusion, without a shared and agreed understanding of the reasons for specific reliability requirements, products may be designed to meet a customer specification without actually meeting the real reliability objectives.","PeriodicalId":270494,"journal":{"name":"Annual Symposium Reliability and Maintainability, 2004 - RAMS","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134378496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent innovation within the industry has led to the consideration of structured reliability centered maintenance techniques to improve maintenance and site performance. This paper presents the application of reliability centered maintenance to high speed, centrifugal dairy separation equipment at two New Zealand dairy sites. A pragmatic, practical approach is demonstrated, and the methodology employed in improving the equipment maintenance is fully described. The paper discusses the limitations of the previous maintenance strategy, and how the reliability centred approach reconciles these limitations in determining new, optimum maintenance activities. The importance of having meaningful, complete data in such an analysis procedure is discussed and the various data sources used in the analysis are presented. The role of the many stakeholders in the optimisation process is also reviewed and it is concluded that the success of the process depends largely on the input, belief and commitment of those stakeholders. The paper concludes that the reliability centered maintenance process presented resulted in an optimised maintenance regime for the separation and clarification equipment under consideration, and that significant benefits are available through such a structured review and determination of optimised maintenance activities.","PeriodicalId":270494,"journal":{"name":"Annual Symposium Reliability and Maintainability, 2004 - RAMS","volume":"56 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132121362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wind energy resources are being increasingly recognized as cost effective generation sources in bulk power generation. In the modern age, we need failure-free electric supply. This leads to reliable supply, since most of the failures occur due to insufficient generation. The generation system reliability evaluation has become the most important component of power system reliability. This paper presents the results of a case study concerning reliability evaluation of Ramgiri wind farm in Andhra Pradesh, India. It consists of several 250 KW wind electric generators connected to the grid. The unit-wise data was collected for 2 years. The failure and repair rates were presented. \" We developed and used a method of sequential addition algorithm through a computer program in 'C' language\". From the results, one can go for system planning for certain base loads and addition of wind turbine generators and selection of wind site.","PeriodicalId":270494,"journal":{"name":"Annual Symposium Reliability and Maintainability, 2004 - RAMS","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132694604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
