Research Article Weibull Model Allowing Nearly Instantaneous Failures
نویسندگان
چکیده
A generalized Weibull model that allows instantaneous or early failures is modified so that the model can be expressed as a mixture of the uniform distribution and the Weibull distribution. Properties of the resulting distribution are derived; in particular, the probability density function, survival function, and the hazard rate function are obtained. Some selected plots of these functions are also presented. An R script was written to fit the model parameters. An application of the modified model is illustrated.

On the Suitability of the Weibull Distribution for the Approximation of Machine Failures
In this research we investigate how the Weibull distribution is suited as an alternative to common approaches in the stochastic modeling of machine downtimes and times between failures. We present an algorithm that automatically calculates Weibull parameters from machine data based on the SEMI E10 standard. We also discuss the question whether sampling shop-floor data should not only include fi...
متن کاملStudies on Some Inventory Model for Deteriorating Items with Weibull Replinishment and Generalised Pareto Decay Having Demands as Function of on Hand Inventory
Inventory models play an important role in determining the optimal ordering and pricing policies. Much work has been reported in literature regarding inventory models with finite or infinite replenishment. But in many practical situations the replenishment is governed by random factors like procurement, transportation, environmental condition, availability of raw material etc., Hence, it is nee...
متن کاملStatistical Inference of a Competing Risks Model with Modified Weibull Distributions
Abstract Statistical inferences of the parameters included in a competing risks model are presented. It is assumed here that the causes of failures may occur at times that follow modified Weibull distributions. The case of Weibull distributions can be derived as special case of the problem studied in this paper. The maximum likelihood procedure is used to get the point estimations and asymptoti...
متن کاملAnalysis of left truncated and right censored competing risks data
In this article, the analysis of left truncated and right censored competing risks data is carried out, under the assumption of the latent failure times model. It is assumed that there are two competing causes of failures, although most of the results can be extended for more than two causes of failures. The lifetimes corresponding to the competing causes of failures are assumed to follow Weibu...
متن کاملPrediction of the curing time to achieve maturity of the nano-cement based concrete using the Weibull distribution model: A complementary data set
This data article provides a comparison data for nano-cement based concrete (NCC) and ordinary Portland cement based concrete (OPCC). Concrete samples (OPCC) were fabricated using ten different mix design and their characterization data is provided here. Optimization of curing time using the Weibull distribution model was done by analyzing the rate of change of compressive strength of the OPCC....
