Zusammenfassung:	A particle swarm optimization method was used to investigate the corrosion fatigue problem. The optimization procedure is used in redesigning the operating environment to achieve desired corrosion-fatigue properties for an aircraft panel/material. The operating parameters that would cause a structure to have maximum fatigue properties were obtained from the optimization simulation. The results of operating parameters obtained through the optimization procedure are reasonable and demonstrate the feasibility of the approach for estimating the corrosion fatigue of aging structures.
