Introduction of welding robots in shipyards

The great participation of direct human work characterizes today's shipbuilding industry. The actual status in the development of science and technology makes possible the replacement of humans with industrial robots in a large number of these work places. The strategy of the introduction of industrial robots in shipyards has to be adapted to existing working conditions, and the introduction has to be done gradually. This paper deals with a new method for priority setting of industrial robot work places and structures for welding operations in shipyards, based on the analytic hierarchy process. The numerical measure of priority of work places is based on the comparative pairwise judgments of social, psychological, technological, technical, safety, productivity and economical factors on different working locations. After the priority work places and priority working operations are chosen, the priority structures of adequate industrial robots are suggested according to their geometric, kinematic, dynamic an...
