The object of the present invention is to provide a flat-panel-display substrate which is high in heat resistance, of which the coefficient of thermal expansion is approximated to that of a thick film dielectric layer, which is low at high temperatures in reactivity with the lead-doped thick film dielectric layer, and which can be made to have a large area. A local data store is coupled between a central data store and a system carrying out a workflow. The carrier dispatch encoding table and its transportation duties correspond to chromosomes and genes in a genetic algorithm. The two positioning boards are disposed on the casing plane and correspond in position to the positioning sides.
