This places a lot of focus on the reliability of the spacecraft from the early design phase, through the manufacturing process and up until after the spacecraft has been launched and put into service. In this paper, the authors discuss methods with primary focus on the reliability of an in-orbit satellite fleet, i.e. a collection of satellites that have been placed successfully in orbit. Traditional methods developed primarily for reliability predictions of a single satellite with no flight history are not adequate for this purpose. Realistic reliability predictions for an in-orbit satellite fleet must address the flight history (launch date and observed in-orbit failures) of each individual satellite, and furthermore spacecraft units are often observed to have nonconstant hazard rates, significantly different from those that can be calculated using military handbooks. To obtain reliability predictions for a satellite fleet with individual flight histories, nonconstant unit hazard rates, and complicated redundancy configurations, Monte-Carlo simulation is a very useful tool, because it can handle complex models in contrast to most analytical tools.","PeriodicalId":143102,"journal":{"name":"Annual Reliability and Maintainability Symposium 1995 Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1995-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124102300","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}

System readiness is strongly dependent upon the reliability of each electronic subsystem, its associate circuit card assemblies and individual components. Currently missing in electronic system reliability assessment is computer simulation from the circuit card level upward in the electronic system. The performance of the electronic box directly effects the reliability of the electronics inside the box since the box filters many environmental loads such as shock and vibration, temperature change, etc. A research effort has been initiated by the CALCE Electronic Packaging Research Center, sponsored by the Defense Modeling and Simulation Office (DMSO), to develop a software program to perform electronic box-level reliability assessment. In addition to the box level assessment, more reliable dynamic load information will be available from the program to be transmitted downward to the PWB and component level for further reliability assessment. A description is presented in this paper of the software program that has been developed. Further improvement of the software tool will continue to increase its robustness and sophistication by incorporating users suggestions.","PeriodicalId":143102,"journal":{"name":"Annual Reliability and Maintainability Symposium 1995 Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1995-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126419209","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}

The basis for this performance parameter is presented from two perspectives; based either on previous experience in other reliability growth tests when data are available, or by subjective assessment of a given corporate culture when data are not available. Quantification of this parametric variable with data is presented by normalizing past performance with the reliability growth program goals. Development of the parametric variable without data is accomplished through the characterization of attributes that are indicative of the corporate culture. Five case studies were used to develop the performance parameter based on test data and by subjective assessment of capability. Although the results of these estimates of the performance parameter varied, they were reasonably close. Based on results of uncertainty propagation analyses, it is reasonable to conclude that a modified TGP model provides a conservative estimate of the risk involved in achieving reliability growth goals. This conclusion is based on the model's durability in sustaining the introduction of uncertainty into the existing failure rate parameters as well as into the performance parameter.","PeriodicalId":143102,"journal":{"name":"Annual Reliability and Maintainability Symposium 1995 Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1995-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134599616","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}

The RAAF recognizes that R&M are principal determinants of the level of operational availability that will be achieved by weapon systems and key factors of life cycle cost. R&M are therefore important performance parameters relevant in the acquisition process. To ensure clarity, the RAAF acquisition process is explained and contrasted with the US process. R&M is assured in RAAF weapon system acquisition programs in the following manner: (1) the R&M requirements are developed in a logical manner from operational preparedness objectives for the weapon system; (2) R&M requirements are quantitatively specified; (3) competing tenderers for the weapon system development propose and submit self devised R&M program plans to achieve the R&M performance requirements; (4) prospective contractor proposals are reviewed and compared using the Reliability Guide; (5) the successful tenderer assumes the commercial risk of achieving all of the system performance requirements including R&M; and (6) monitoring of the contractor during system development is \"hands-off\" but \"eyes open\". This approach to R&M in acquisition was chosen after consideration of the acquisition process in a number of countries, especially the US and UK. The approach is similar to that used by the UK and has been in use in Australia now for about two years.","PeriodicalId":143102,"journal":{"name":"Annual Reliability and Maintainability Symposium 1995 Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122068585","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}
