In order to reduce the localization deformation of aircraft thin-wall components

the layout optimization method is proposed based on 0-1 integer programming. The method is used for aircraft skin pre-assembled to accommodate automatic drilling and riveting. Firstly

the layout optimization problem is transformed to 0-1 integer programming problem on the basis of the “N-2-1” position principle. Secondly

the optimization model of location layout recursive is established taking the minimum of maximum deformation of thin-walled parts as the target of optimization. The maximum deformation is obtained through parametric modeling analysis of thin-walled parts positioning system. Finally

the layout optimization is fulfilled using the hybrid particle swarm optimization algorithm through stepwise solving strategy.
