Probabilistic structural optimization

The objective of this review is to present a brief but comprehensive view of probabilistic structural optimization (PSO). An historical perspective is presented, basic concepts and various problem formulations are discussed, and recent developments focusing on practical applications are highlighted. A particular emphasis is placed upon the use of PSO based on consideration of life-cycle cost in the process of design selection for new structural systems and in the optimal operation of existing ones. Finally, conclusions are drawn and directions for further research are identified.
