在工程中一个众所周知的原则是，在组件级的冗余通常比在系统级的冗余更有效的可靠性。这里，冗余仅仅意味着组件并联连接。基于这一原理，本文研究了一个更一般的N中取K系统的最优装配问题。我们考虑两个组装系统：一个是通过在系统级组装一个$k$ -out-of- $n$系统和一个$l$ -out-of- $m$系统，另一个是通过在组件级组装它们。在对$（n，k）$和$（m，l）$作适当假设的情况下，得到了两个装配系统随机比较的一些结果。从这个结果，一些有用的原则，组装$K$ -出- $N$ -系统的最佳建议。两个数值例子来说明我们的结果。
A well-known principle in engineering is that redundancy at the component level is generally more reliability effective than that at the system level. Here, the redundancy simply means that components are connected in parallel. Motivated by this principle, in this paper, a more general problem of assembling $K$ -out-of- $N$ systems optimally is studied. We consider two assembled systems: one is by assembling a $k$ -out-of- $n$ system and a $l$ -out-of- $m$ system at the system level, and the other is by assembling them at a component level. With some appropriate assumptions on $(n,k)$ and $(m,l)$ , some results on stochastic comparisons of the two assembly systems are derived. From this result, some useful principles for assembling $K$ -out-of- $N$ -systems optimally are proposed. Two numerical examples are given to illustrate our results as well.
