Abstract
A method and system for optimizing the assembly workcell layout in the context of industrial robotic CAD/CAM/CAE software products. The criterion to be minimized is the cycle time for completing a given sequence of operations, which is achieved by determining the relative positions of peripheral machines on the workcell floor. The method is constructive: each machine is placed one at a time in the robot neighborhood, by means of a modified simulated annealing method. This method yields several possible and optimal positions for a machine and several layouts are thus obtained at the end of execution.
