A study on multi-level redundancy allocation in coherent systems formed by modules
نویسندگان
چکیده
The present work studies the effect of redundancies on reliability coherent systems formed by modules. Different at components’ level versus modules’ are investigated, including active and standby redundancies. For that, a new model is presented. This takes into account dependence among components, as well as, modules system. In both cases, structure modeled copula functions. Several results provided to compare consisting heterogeneous components. comparisons distribution-free with respect particular, we consider cases when components in independent connected (or not) series, dependent within it assumed that can be dependent. Furthermore, case which each module identically distributed (dependent or independent) also considered. We illustrate theoretical several examples.

A Multi Objective Optimization Model for Redundancy Allocation Problems in Series-Parallel Systems with Repairable Components
The main goal in this paper is to propose an optimization model for determining the structure of a series-parallel system. Regarding the previous studies in series-parallel systems, the main contribution of this study is to expand the redundancy allocation parallel to systems that have repairable components. The considered optimization model has two objectives: maximizing the system mean time t...
متن کاملSolving a Redundancy Allocation Problem by a Hybrid Multi-objective Imperialist Competitive Algorithm
A redundancy allocation problem (RAP) is a well-known NP-hard problem that involves the selection of elements and redundancy levels to maximize the system reliability under various system-level constraints. In many practical design situations, reliability apportionment is complicated because of the presence of several conflicting objectives that cannot be combined into a single-objective functi...
متن کاملA New Nonlinear Multi-objective Redundancy Allocation Model with the Choice of Redundancy Strategy Solved by the Compromise Programming Approach
One of the primary concerns in any system design problem is to prepare a highly reliable system with minimum cost. One way to increase the reliability of systems is to use redundancy in different forms such as active or standby. In this paper, a new nonlinear multi- objective integer programming model with the choice of redundancy strategy and component type is developed where standby strategy ...
متن کاملA Memetic Algorithm For Multi-level Redundancy Allocation Problem
Redundancy allocation problems (RAPs) have attracted much attention for the past thirty years due to its wide applications in improving the reliability of various engineering systems. Since RAP is an NP-hard problem and exact methods are only applicable to small instances, various heuristic and meta-heuristic methods have been proposed to solve it. In the literature, most studies on RAPs have b...
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...
