Abstract

This study presents Markov models for assessing the availability and the mean time to failure (MTTF) of a k-out-of n: G system with exponentially distributed time between failures and repair times. Generalised analytical expressions for the steady-state availability and MTTF are derived. Furthermore, numerical examples are used to illustrate the performance of several models along with the cost of adopting different configurations.

可修复的可用性和平均故障间隔时间<i>k-out-N: G</i>具有相同组件的系统

本研究提出了用于评估k-out (n: G)系统的可用性和平均故障时间(MTTF)的马尔可夫模型，该系统的故障和修复时间之间的时间呈指数分布。导出了稳态可用性和MTTF的广义解析表达式。此外，数值算例说明了几种模型的性能以及采用不同结构的成本。

期刊介绍： In today''s fast-paced business environment, even with an abundance of information, decision-making can be complex and slow. As floods of data emerge, effective information processing is sought as a panacea. With the ever-present spectre of uncertainty, sound decisions are key. As a consequence of the various conflicts/dilemmas, employment of efficient data management leading to better decision-making is the goal. Organisations must employ effective information management/decision-making processes at each critical stage of their functions. IJIDS addresses the issues involved in this.
