Modified harmony search applied to reliability optimization of complex systems

Abstract

This paper proposes an Improved Modified Harmony Search Algorithm with constraint handling with application to redundancy allocation problems in reliability engineering. The performance of Improved Modified Harmony Search is being compared with that of the original Harmony Search, Modified Great Deluge Algorithm, Ant Colony Optimization, Improved Non-Equilibrium Simulated Annealing and Simulated Annealing. It is observed that Improved Modified Harmony Search requires less number of function evaluations compared to others.
