As populations age and young workers reject work requiring repetitive operations, factories around the world are turning to robots. It is estimated that the US has 176 robots for every 10,000 workers, with South Korea (531) and Germany (301) leading the charge and China, with its investment in being a leading maker of robots, expected to advance quickly (90,000 robots installed by 2016, one-third of the world’s total). You are a worldwide manufacturer of industrial equipment with 10 plants and more than 10,000 manufacturing employees and supervisors. Some of your plants are represented by unions. Create the sampling design to study robotics as a solution to a manufacturing worker shortage.
