Digital logic boards and assembled video display terminals are the author's primary focus; however, the principles of COST apply to all electronic components.<<ETX>>","PeriodicalId":430861,"journal":{"name":"Proceedings., Annual Reliability and Maintainability Symposium","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122657898","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}

He argues that there is a need for more supportable and affordable weapon systems, and that the services are struggling with how to make that happen. He suggests that the best approach is one that derives the conceptual design process for least total ownership costs, and that once that design architecture has been identified, acquisition and management programs should be implemented based on that design architecture. He further argues that requests for proposal should require the contractor to justify why he feels his design is optimized for supportability and affordability, and should back up that requirement with scoring contracts on their multiphase costs.<<ETX>>","PeriodicalId":430861,"journal":{"name":"Proceedings., Annual Reliability and Maintainability Symposium","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122331163","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}

Appropriate corrective actions can then be initiated prior to the production of additional units and existing lower quality units may be fixed to improve their reliability. A useful measure of quality for both tested and untested units is the posterior probability of failure, which is based upon the discriminant function and the empirical priors. Some phases of discriminant analysis are formulated in terms of normality, but can be practically robust to that assumption. Graphical displays provide useful insight into this aspect of the analysis. The sensitivity of the discriminant line (hyperplane) to changes in the sample point configuration is also discussed.<<ETX>>","PeriodicalId":430861,"journal":{"name":"Proceedings., Annual Reliability and Maintainability Symposium","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133439674","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}

Experimental data indicate that infrared thermography provides a method of measuring the temperatures of powered PWBs (printed wiring boards). The overall difference between the measured temperature profile and the calculated temperature profile is within 10%. The discrepancies are thought to be due to uncertainties in material properties and the experimental methods.<<ETX>>","PeriodicalId":430861,"journal":{"name":"Proceedings., Annual Reliability and Maintainability Symposium","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131713578","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}
