4. NB The failure to start is only taken into account at t 0 3 1 4 WBL Weibull This law has three parameters alpha beta and t0 It describes the behaviour of a component which is not repairable and which does not fail to start Its specific feature is that it takes account of the component s young and old periods Parameters e Alpha Factor scale parameter e Beta Factor form parameter e TO Time location parameter The law is defined as follows p t t O t 1 exp a The significance of this law is that new distributions can be tested by varying the beta factor e If Beta is less than 1 the failure rate decreases and the law then allows the period when the component is young to be taken into account e If Beta is greater than 1 the failure rate increases and the law then allows the component s ageing period to be taken into account e If Beta is equal to 1 the Weibull law is equivalent to the exponential law 3 1 5 TPS Simple Periodic Test law This law allows a component which fails to be represented according to an exponential distribution law and whose failure is found during a periodic test The repair is then carried out instantaneously Parameters e Lambda Rate failure rate e Tau Duration test period time interval between two consecutive tests e TO Time date of first test The law is defined as follows t 0 A t t mod r i E otherwise User M
