Abstract
This paper presents a novel multiobjective evolutionary algorithm, called compromise rank genetic programming(CRGP), to realize a nonlinear system design (NSD) for disaster management automatically. This NSD issue isformulated here as a multiobjective optimization problem (MOP) that needs to optimize model performance andmodel structure simultaneously. CRGP combines decision making with the optimization process to get the final globalsolution in a single run. This algorithm adopts a new rank approach incorporating the subjective information to guidethe search, which ranks individuals according to the compromise distance of their mapping vectors in the objectivespace. We prove here that the proposed approach can converge to the global optimum under certain constraints. Toillustrate the practicality of CRGP, finally it is applied to a postearthquake reconstruction management problem. Experimental results show that CRGP is effective in exploring the unknown nonlinear systems among huge datasets,which is beneficial to assist the postearthquake renewal with high accuracy and efficiency. The proposed method is foundto have a superior performance in obtaining a satisfied model structure compared to other related methods to addressthe disaster management problem.
