Abstract This paper is concerned with the optimal number of redundant allocation to n -component coherent systems consisting heterogeneous dependent components. We assume that system built up L groups different components, $L\geq 1$ , where there are $n_i$ components in group i and $\sum_{i=1}^{L}n_i=n$ . The problem interest allocate $v_i$ active each component type $i=1,\dots, L$ To get value...

Traditionally in redundancy allocation problem (RAP), it is assumed that the redundant components are used based on a predefined active or standby strategies. Recently, some studies consider the situation that both active and standby strategies can be used in a specific system. However, these researches assume that the redundancy strategy for each subsystem can be either active or standby and d...

A simple computational procedure has been developed by using Monte Carlo for allocating redundancy among subsystems so as to achieve maximum reliability of a complex systems subjected to multiple constraints which may be linear, non linear separable or non separable. Two examples of linear, non linear separable and non separable constraints with having twenty problems are solved.

This article addresses the problem of redundancy and reliability allocation in the operational dimensioning of an automated production system. The aim of this research is to improve the global reliability of the system by allocating alternative components (redundancies) that are associated in parallel with each original component. By considering a complex componential approach that simultaneous...

We address the redundancy allocation of a series repairable system with multiple k-out-of-n subsystems with each subsystem following shut-off rule. The objective of the problem is to find the optimal number of repairmen and redundant components in each subsystem for optimization of steady-state availability subject to weight, cost and volume constraints. We propose a Particle Swarm Optimization...
