Consecutive expansions of k-out-of-n systems
نویسندگان
چکیده
We introduce consecutive expansions of k–out–of–n systems, which have the property that components are totally ordered by the node criticality relation and with respect to well-known structural importance measures. We propose some formulae to easily compute these measures and study the hierarchies induced for them for large systems.

Number of Minimal Path Sets in a Consecutive-k-out-of-n: F System
In this paper the combinatorial problem of determining the number of minimal path sets of a consecutive-k-out-of-n: F system is considered. For the cases where k = 2, 3 the explicit formulae are given and for k ≥ 4 a recursive relation is obtained. Direct computation for determining the number of minimal path sets of a consecutive-k-out-of-n: F system for k ≥ 4 remains a difficult task. ...
متن کاملRedundancy allocation problem for k-out-of-n systems with a choice of redundancy strategies
To increase the reliability of a specific system, using redundant components is a common method which is called redundancy allocation problem (RAP). Some of the RAP studies have focused on k-out-of-n systems. However, all of these studies assumed predetermined active or standby strategies for each subsystem. In this paper, for the first time, we propose a k-out-of-<em...

متن کاملUsing NSGA II Algorithm for a Three Objectives Redundancy Allocation Problem with k-out-of-n Sub-Systems
in the new production systems, finding a way to improving the product and system reliability in design is a very important. The reliability of the products and systems may improve using different methods. One of this methods is redundancy allocation problem. In this problem by adding redundant component to sub-systems under some constraints, the reliability improved. In this paper we worked on ...
متن کاملOn the Joint Reliability Importance for k-out-of-n Systems
In this paper, the concept of joint reliability importance (JRI) of two or groups of components in a coherent system with independent components have been studied. The JRI is defined as the rate at which the system reliability improves as the reliabilities of the two or groups of components improve. Generally, the sign and the value of the JRI represent the type and the degree of i...
