Abstract

In this article, a modular model is proposed for the reliability modeling of phased mission systems (PMSs) with complicated system behaviors. By the modular method, the system is divided into several levels: system, subsystem, and components. At the component level, the shock effect, including self‐degradation, additional wear and damage caused by shocks, is considered and the component reliability is evaluated. Then, the reliability modeling method of the K/N system consisting of multiple K/N subsystems is proposed, by a mathematics reasoning method. The correctness of the proposed method is also verified by a Monte Carlo (MC) simulation procedure. At last, the modular method is applied at the system level, and the reliability of a practical engineering case, the attitude and orbit control system (AOCS), is evaluated for illustration. Meanwhile, the parameter sensitivity analysis is also carried out for implementation.

具有多个 K/N 子系统和混合冲击的 PMS 可靠性分析模型的模块化模型

本文提出了一种模块化模型，用于对具有复杂系统行为的分阶段任务系统（PMS）进行可靠性建模。通过模块化方法，系统被划分为几个层次：系统、子系统和组件。在组件层面，考虑了冲击效应，包括冲击引起的自退化、额外磨损和损坏，并对组件可靠性进行了评估。然后，通过数学推理方法，提出了由多个 K/N 子系统组成的 K/N 系统的可靠性建模方法。还通过蒙特卡罗（MC）模拟程序验证了所提方法的正确性。最后，在系统层面应用了模块化方法，并对实际工程案例--姿态和轨道控制系统（AOCS）的可靠性进行了评估，以资说明。同时，为便于实施，还进行了参数敏感性分析。

期刊介绍： Quality and Reliability Engineering International is a journal devoted to practical engineering aspects of quality and reliability. A refereed technical journal published eight times per year, it covers the development and practical application of existing theoretical methods, research and industrial practices. Articles in the journal will be concerned with case studies, tutorial-type reviews and also with applications of new or well-known theory to the solution of actual quality and reliability problems in engineering. Papers describing the use of mathematical and statistical tools to solve real life industrial problems are encouraged, provided that the emphasis is placed on practical applications and demonstrated case studies. The scope of the journal is intended to include components, physics of failure, equipment and systems from the fields of electronic, electrical, mechanical and systems engineering. The areas of communications, aerospace, automotive, railways, shipboard equipment, control engineering and consumer products are all covered by the journal. Quality and reliability of hardware as well as software are covered. Papers on software engineering and its impact on product quality and reliability are encouraged. The journal will also cover the management of quality and reliability in the engineering industry. Special issues on a variety of key topics are published every year and contribute to the enhancement of Quality and Reliability Engineering International as a major reference in its field.
