The pyrotechnic control subsystem plays an important role in opening the solar array of a satellite.Assessing the reliability of the subsystem requires determining the level of a control factor that is needed to cause the desired response and energy output with high probability.A two-phase adaptive design to estimate the level of interest is proposed and studied.The convergence of the design is obtained.A simulation study shows that the estimate is very close to its population value and is robust to the initial guess of the design.As an application,the design is used to assess the reliability of a real pyrotechnic control subsystem.
In this paper, the unknown link function, the direction parameter, and the heteroscedastic variance in single index models are estimated by the random weight method under the random censorship, respectively. The central limit theory and the convergence rate of the law of the iterated logarithm for the estimator of the direction parameter are derived, respectively. The optimal convergence rates for the estimators of the link function and the heteroscedastic variance are obtained. Simulation results support the theoretical results of the paper.
