A hybrid approach based on modified particle swarm optimization (MPSO) is proposed to solve the VaR-FRFLM. In this hybrid mechanism, an approximation algorithm is utilized to compute the fuzzy random VaR, a continuous Nbest-Gbest-based PSO and a genotype-phenotype-based binary PSO vehicles are designed to deal with the continuous capacity decisions and the binary location decisions, respectively, and two mutation operators are incorporated into the PSO to further enlarge the search space. A numerical experiment illustrates the application of the proposed hybrid MPSO algorithm and lays out its robustness to the parameter settings when dealing with the VaR-FRFLM. 2010-08-06T08:58:26Z 2010-08-06T08:58:26Z 2010 Book chapter Integrated Uncertainty Management and Applications, vol. 68, p. 209-220 978-3-642-11959-0 1615-3871 (Print) 1860-0794 (Online) http://www.springerlink.com/content/59128247115x645t/ http://hdl.handle.net/123456789/8505 en Advances in Soft Computing Springer-Verlag Berlin Heidelberg |
