Code Workstation Key Task No. C1 SA3 Stator assembly 1. Determine the number of workers required and the corresponding task assignment for achieving a production rate of 650 units per shift in case of assembly line w/o automation. Assume that a worker can be trained in more than one key task. 2. Consider a cell design for ceiling Motor assembly with one operator. What is the resulting capacity? Consider automation 3. How would the cell operate with two workers assigned to the cell? What is the corresponding capacity? Consider automation 4. Repeat 3 with three workers assigned to the cell.
