Abstract and Applied Analysis, 2014, vol. 2014, issue 1

Abstract: This paper focuses on the problem of hedging against seismic risk through the retrofit of transportation systems in large‐scale construction projects (LSCP). A fuzzy random multiobjective bilevel programming model is formulated with the objectives of the retrofit costs and the benefits on two separate levels. After establishing the model, a fuzzy random variable transformation approach and fuzzy variable approximation decomposition are used to deal with the uncertainty. An approximation decomposition‐based multi‐objective AGLNPSO is developed to solve the model. The results of a case study validate the efficiency of the proposed approach.
