چکیده

System reliability-redundancy optimization plays a vital role in realworld applications. Recently, a new meta-heuristic based on swarm intelligence called cat swarm optimization (CSO) algorithm has emerged. CSO is a stochastic optimization paradigm inspired from the natural behavior of cats. To enhance the performance of the CSO algorithm, an improved adaptive CSO (ICSO) algorithm is presented. Both CSO and ICSO approaches were applied to an overspeed protection system for a gas turbine, a benchmark in the reliability-redundancy mixed-integer optimization field. Better results obtained by the ICSO show that the algorithm can be an efficient alternative for solving reliability problems.

Reliability Optimization for Complicated Systems with a Choice of Redundancy Strategies (TECHNICAL NOTE)

Redundancy allocation is one of the common techniques to increase the reliability of the bridge systems. Many studies on the general redundancy allocation problems assume that the redundancy strategy for each subsystem is predetermined and fixed. In general, active redundancy has received more attention in the past. However, in real world, a particular system design contains both active and col...

EMCSO: An Elitist Multi-Objective Cat Swarm Optimization

This paper introduces a novel multi-objective evolutionary algorithm based on cat swarm optimizationalgorithm (EMCSO) and its application to solve a multi-objective knapsack problem. The multi-objective optimizers try to find the closest solutions to true Pareto front (POF) where it will be achieved by finding the less-crowded non-dominated solutions. The proposed method applies cat swarm optim...

A Modified Particle Swarm Optimization Algorithm for Reliability Redundancy Optimization Problem

In this paper, a modified particle swarm optimization (MPSO) algorithm is proposed to solve the reliability redundancy optimization problem. This algorithm modifies the strategy of generating new position of particles. For each generation solution, the flight velocity of particles is removed. Whereas the new position of each particle is generated by using difference strategy. Moreover, an adapt...
