Reliability allocation for components, redundancy allocation, and reliability redundancy
allocation are of great significance for system reliability designing. Generally, standby …

In this paper, a single-objective redundancy allocation problem (RAP) is considered for a
series system with k-out-of-n subsystems. In each subsystem, the components are binary …

This paper considers the mixed-integer non-linear optimization of reliability–redundancy
allocation problem (RRAP) to determine simultaneous reliability and redundancy level of …

During the last decade, system reliability optimization has been widely investigated. New
strategies have been introduced recently to improve the overall system reliability, such as …

We propose a mathematical model for optimizing multiple redundancy-reliability systems
known as mega-systems. The system components are multi-state and the universal …

A simulation-based optimization (SBO) method is proposed to handle multi-objective joint
availability-redundancy allocation problem (JARAP). Here, there is no emphasis on …

This paper proposes a variant of the Non-dominated Sorting Genetic Algorithm (NSGA-II) to
solve a novel mathematical model for multi-objective redundancy allocation problems …

Determining the positions of facilities, and allocating demands to them, is a vitally important
problem. Location-allocation problems are optimization NP-hard procedures. This article …

In this paper, a new version of the reliability-redundancy allocation problem (RRAP) is
introduced. In RRAPs, the reliability of the components used in a subsystem is considered …

System reliability depends on inherent mechanical and structural aging factors as well as on
operational and environmental conditions, which could enhance (or smoothen) such factors …
