摘要

基于不确定性理论，研究了无充足样本情况下热备用串并联系统的可靠性问题。假设系统元件的寿命遵循具有不确定参数的独立不确定分布。针对热备串并联系统，开发了三种不同的开关模式，包括绝对可靠模式、离散模式和连续模式。此外，还将冷备串并联系统作为特例进行了讨论。分析了各模型的可靠性函数和平均失效时间。最后通过一个带有不同开关的系统算例说明了所提模型的应用和有效性。

(1912-5631) Reliability analysis of a warm standby series-parallel system with different switches and bi-uncertain lifetimes

The reliability of a warm standby series-parallel system without adequate samples is studied based on the uncertainty theory. It is assumed that the lifetimes of system elements follow independent uncertainty distributions with uncertain parameters. Three different switch models, including absolutely reliable mode, discrete mode and continuous mode, are developed for the warm standby series-parallel system. Besides, the cold standby series-parallel system is discussed as a special case. The reliability function and mean time to failure of each developed model are analyzed. A numerical example for the system with different switches is implemented to illustrate the application and efficiency of the proposed models.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
