摘要:In this paper the geometric process is used for the analysis of accelerated life testing under constant stress for Pareto Distribution. Assuming that the lifetimes under increasing stress levels form a geometric process, estimates of the parameters are obtained by using the maxim...

摘要:Abstract(#br)A step-stress accelerated life test for two stress variables is developed. The time to failure follows the Exponentiated Weibull distribution. This paper presents a SSALT model assuming a 3-parameter Exponentiated Weibull distribution for the failure time. The inclus...

摘要:Abstract(#br)The optimum times of varying stress level for simple stress plan under a cumulative exposure model using the Power Function distribution are determined for a wide range of values of the model parameters. The scale parameter of the power function distribution at ...

摘要:Abstract(#br)Step stress accelerated life testing model is presented to obtain the optimal hold time at which the stress level is changed. A Mukherjee-Islam Failure model is assumed for the failure time at any constant stress level and a cumulative exposure model is assumed....
