Reliability Analysis of Military Vehicles Based on Censored Failures Data

نویسندگان

چکیده

The paper proposes a methodology of reliability testing as applied to vehicles used in military transport systems. After estimating the value function using Kaplan–Meier estimator, models were developed and analysed. neural model, which achieved correlation coefficient R exceeding 0.99, was determined fit empirical data best. On basis approximated several models, characteristics tested sample determined. Plots failure probability density for all three had similar courses over significant part domain. A intensity also determined, varied between models. For exponential Weibull expected mileage failures calculated, proved impossible model. proposed is capable modelling based on observation an assumed period exploitation process selected group vehicles.

Reliability analysis of subway vehicles based on the data of operational failures

A large quantity of failure data for subway vehicles was collected from long-term field investigations and technical exchanged. These failure data has a guiding significance for preserving subway system. By preprocessing (screening, refining, and classification) the original data and statistical analysis, we establish some selected model, then we use A-D test to verify the degree of fitting in ...

Bayesian Analysis of Censored Spatial Data Based on a Non-Gaussian Model

Abstract: In this paper, we suggest using a skew Gaussian-log Gaussian model for the analysis of spatial censored data from a Bayesian point of view. This approach furnishes an extension of the skew log Gaussian model to accommodate to both skewness and heavy tails and also censored data. All of the characteristics mentioned are three pervasive features of spatial data. We utilize data augme...

Statistical Analysis of Reliability Data in Ramdomly Censored Life Testing

For independent nonnegative continuous random variables Xl, ... , Xb Z = min (Xl, ... , Xk) and fj;(i=1, ... , k), where fji = 1 if Z = Xi and fji = 0 otherwise, are statistically independent random variables if and only if the distribution of Xi is written as Fi(X) = 1 exp(-piQ(X)) (i=1, ... , k). From this characterization theorem for the random variable Xi, an unbiased estimate for failure r...

Analysis of Dependently Censored Data Based on Quantile Regression.

Dependent censoring occurs in many biomedical studies and poses considerable methodological challenges for survival analysis. In this work, we develop a new approach for analyzing dependently censored data by adopting quantile regression models. We formulate covariate effects on the quantiles of the marginal distribution of the event time of interest. Such a modeling strategy can accommodate a ...

Analysis of Hybrid Censored Data from the Lognormal Distribution

The mixture of Type I and Type II censoring schemes, called the hybrid censoring. This article presents the statistical inferences on lognormal parameters when the data are hybrid censored. We obtain the maximum likelihood estimators (MLEs) and the approximate maximum likelihood estimators (AMLEs) of the unknown parameters. Asymptotic distributions of the maximum likelihood estimators are used ...
