The concept of state tree analysis (STA), generalized module, and modular decomposition are introduced. The cumulative efficiency index of this method is developed and is found to be satisfactory. The method is comprehensive, applicable and easy to use by professionals in engineering to compute and analyze reliability of complex s-coherent multistate systems. A hypothetical airborne radar system is used as a case study to illustrate, step-by-step, the multilevel modular decomposition approach. The results are compared with the binary model.<<ETX>>","PeriodicalId":430861,"journal":{"name":"Proceedings., Annual Reliability and Maintainability Symposium","volume":"55 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":"129840864","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}

A fix-effectiveness factor is defined to be the percent decrease in a problem failure mode due to a corrective action. The approach utilizes the reliability growth projection model developed by L.H. Crow (1974). This model projects the reliability at the beginning of phase II of development testing based on failure data from phase I of development testing and assumes subjective fix-effectiveness factors. The authors reversed this process to estimate an average fix-effectiveness factor using the model and failure data from phase I and phase II. This approach is based on a number of assumptions which are developed and discussed in detail. Examples illustrating the practical application of the procedure are given.<<ETX>>","PeriodicalId":430861,"journal":{"name":"Proceedings., Annual Reliability and Maintainability Symposium","volume":"1 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":"128417021","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 primary objective of the program is to verify quality and reliability of replacement parts for the Center's customers. Five general programs have been developed to monitor and verify the key areas of quality relative to DESC procurements. Test results indicate increased quality with sampling. The DESC test facility is increasing the number of federal supply classes now sampled, as well as expanding their basic electronic testing capacity to include more environmental and specialized testing. Although areas such as environmental stress screening (ESS) are being studied, part characterization is identified as a much more urgent need.<<ETX>>","PeriodicalId":430861,"journal":{"name":"Proceedings., Annual Reliability and Maintainability Symposium","volume":"5 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":"126925953","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}

This additional information is valuable in the R&M (reliability and maintainability) and logistics areas and is available early on in the development process. The model, which is based on a modified Poisson probability distribution, computes the number of initial spares required in inventory to assure at a preselected probability (confidence level) that a spare is available. It takes into account the number of units in service, failure rate for each replaceable unit, average turnaround time for repair or time to secure a replacement unit, confidence level selected for having a spare available, the support period, operational time, duty cycle, and whether units are screened before being returned for repair. The model is applicable to simple systems or to complex, multilevel systems and works equally well for repairable or discardable parts.<<ETX>>","PeriodicalId":430861,"journal":{"name":"Proceedings., Annual Reliability and Maintainability Symposium","volume":"11 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":"121064293","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}

An automated state probability model called RELCOM2 is presented that can facilitate analysis, and assure accurate evaluation. The model can analyze a complex arrangement of up to six blocks, each comprised of up to 99 units. Larger numbers of units may be analyzed, but standard block diagram display formats are limited to 99. Since redundancy relationships in systems like AEGIS use large numbers of parallel units, such capacity is important in their analysis.<<ETX>>","PeriodicalId":430861,"journal":{"name":"Proceedings., Annual Reliability and Maintainability Symposium","volume":"2 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":"123820503","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}

This solution embeds reliability and maintainability analytical tools directly into the designer's CAD/CAE (computer-aided design/engineering) workstations.

For a large complex system, top-down analysis can be more efficient. The authors present, as an example, a high-pressure air heater and its pressure controller, which are part of a hypersonic wind tunnel. The failure effect of concern is heater overpressurization. At least one failure in the pressure controller and one or more in the application safety features would be required for overpressure to occur. It is therefore concluded that there are no SFPs for heater overpressurization in this wind tunnel.<<ETX>>","PeriodicalId":430861,"journal":{"name":"Proceedings., Annual Reliability and Maintainability Symposium","volume":"32 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":"121433908","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}
