All existing safety standards are based on ‘worst-case’ analyses: this implies that if an event is considered realistically possible then protective measures must be applied as if its probability were unity. Effects that are considered very improbable are effectively assigned a probability of zero. This ‘binary’ approach is unsatisfactory for a number of reasons: in particular, the concatenation of apparently realistic worst-case factors frequently leads to unacceptably ‘pessimistic’ conclusions. The solution to such problems is to evaluate the probability of occurrence of each step in the hazard process. The paper reviews the bases of the new British Standards covering these hazards and presents an analysis of some of the probabilistic factors involved.</p></div>","PeriodicalId":101070,"journal":{"name":"Reliability Engineering","volume":"17 2","pages":"Pages 139-153"},"PeriodicalIF":0.0,"publicationDate":"1987-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0143-8174(87)90012-6","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73737257","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}

Models of stochastic dependence include common cause failures and deal with component failures. They are conditioned on a set of parameters whose ranges of values and their correlations are assessed in the state-of-knowledge models. It is argued that the parametric stochastic models represent the class of failure causes that are not explicitly modeled. Three such stochastic models are examined: the Basic Parameter (BP) model, the Multiple Greek Letter (MGL) model, and the Multinomial Failure Rate (MFR) model. Two problems of the MGL model are discussed. The first has to do with the definition of the parameters. It is shown that β, γ, etc., of the MGL model are defined with reference to a specific component and are used improperly in the statistical calculations. The second problem stems from the fact that the MGL parameters are defined in terms of component failures rather than the events that cause their failures. This results in an artificial increase of the strength of the statistical evidence. The multivariate Dirichlet distribution is used as the state-of-knowledge distribution in the MFR model, since it can model the correlations between the parameters and is a conjuga distribution with respect to the multinomial distribution, thus facilitating Bayesian updating. The Dirichlet distribution can also be used with the BP model to represent the analyst's state of knowledge concerning the numerical values of the parameters of this model.</p></div>","PeriodicalId":101070,"journal":{"name":"Reliability Engineering","volume":"18 3","pages":"Pages 177-195"},"PeriodicalIF":0.0,"publicationDate":"1987-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0143-8174(87)90097-7","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89974427","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}
