Abstract

When strength and stress variables follow the exponential Frechet distribution with different shape parameters and common scale parameters, the multicomponent stress-strength reliability model of an s-out-of-k system is studied in this paper. Based on samples from stress and strength distributions, the maximum likelihood estimation of the model parameters is obtained. The asymptotic confidence interval for the system reliability is also calculated. The comparison of the reliability estimates based on small sample is given by Monte-Carlo simulation.

基于指数Frechet分布的多分量应力强度可靠性估计

本文研究了不同形状参数和通用尺度参数下强度和应力变量服从指数Frechet分布的s-out- k系统多分量应力-强度可靠性模型。基于应力和强度分布的样本，得到了模型参数的最大似然估计。计算了系统可靠性的渐近置信区间。通过蒙特卡罗仿真，对基于小样本的可靠性估计进行了比较。

期刊介绍： The main aims of Thermal Science to publish papers giving results of the fundamental and applied research in different, but closely connected fields: fluid mechanics (mainly turbulent flows), heat transfer, mass transfer, combustion and chemical processes in single, and specifically in multi-phase and multi-component flows in high-temperature chemically reacting flows processes present in thermal engineering, energy generating or consuming equipment, process and chemical engineering equipment and devices, ecological engineering, The important characteristic of the journal is the orientation to the fundamental results of the investigations of different physical and chemical processes, always jointly present in real conditions, and their mutual influence. To publish papers written by experts from different fields: mechanical engineering, chemical engineering, fluid dynamics, thermodynamics and related fields. To inform international scientific community about the recent, and most prominent fundamental results achieved in the South-East European region, and particularly in Serbia, and - vice versa - to inform the scientific community from South-East European Region about recent fundamental and applied scientific achievements in developed countries, serving as a basis for technology development. To achieve international standards of the published papers, by the engagement of experts from different countries in the International Advisory board.
