Abstract

In most modern systems, the importance of all system components is different from each other, and we refer to this importance as weights. In weighted-consecutive-

k

system, each component has its own positive integer weight. The system will fail only when the total weight of successive failed components reaches

k

. We extend the weighted-consecutive-

k

system model by proposing weighted-consecutive-

k

systems having shared components between neighboring subsystems. We have demonstrated the formulas for determining the reliability of weighted-consecutive-

k

systems with various cases based on the state of the first and/or last component(s) using recursion. On this basis, the steps of reliability calculation for linear and circular structures sharing one component and linear structures sharing multiple components are given. Finally, give some examples and the influence of different choices of shared components and independent components and

k

on system reliability is studied.

具有共享组件的加权连续k系统的线性和圆形可靠性建模

在大多数现代系统中，所有系统组件的重要性彼此不同，我们将这种重要性称为权重。在加权连续k系统中，每个组件都有自己的正整数权重。当连续失效组件的总权重达到k时，系统才会失效。我们通过提出相邻子系统之间具有共享组件的加权连续k系统，扩展了加权连续k系统模型。我们已经证明了公式确定的可靠性加权连续k系统与各种情况下，基于状态的第一个和/或最后一个组件(s)使用递归。在此基础上，给出了单构件线性结构和多构件线性结构的可靠度计算步骤。最后，通过实例研究了共享组件、独立组件和k的不同选择对系统可靠性的影响。

期刊介绍： Elsevier publishes Reliability Engineering & System Safety in association with the European Safety and Reliability Association and the Safety Engineering and Risk Analysis Division. The international journal is devoted to developing and applying methods to enhance the safety and reliability of complex technological systems, like nuclear power plants, chemical plants, hazardous waste facilities, space systems, offshore and maritime systems, transportation systems, constructed infrastructure, and manufacturing plants. The journal normally publishes only articles that involve the analysis of substantive problems related to the reliability of complex systems or present techniques and/or theoretical results that have a discernable relationship to the solution of such problems. An important aim is to balance academic material and practical applications.
