The process at GF involves two steps, Frame Construction and Mounting. There is one Frame Construction Station and one worker at Mounting . The Frame Construction Station handles the artwork in batches. The batch size is set to be 6 pieces of works/batch . A 5-minute setup for EACH piece of art is required before the batch processing . Then the frames for the whole batch of artworks will be constructed all together , which takes on average 30 minutes . These 30 minutes processing time does not change when the batch size changes . At Mounting , art pieces are matted and placed in a frame . Mounting is largely a manual operation and does not require a set up . The worker at the mounting finishes one piece of artwork in 15 minutes .

the stage capacity frame construction is _ pieces/per hour
