The ABC Company is planning to launch a new product and will build a new plant to manufacture the parts for the new product. The product will include 30 different models. The annual production of each model is expected to be 3500 units. Each product will be assembled of 12 components. All processing of parts will be accomplished in one factory. There are, on average, five processing steps required to produce each element, and each processing step takes three minutes (This includes an allowance for set up time and part handling). All processing operations are performed at workstations, each consisting of a production machine and a human worker. How many workers will be required in the plant, knowing that the factory operates one shift (3500 hours/year)?
