W-NXT is a manufacturing corporation whose product is a console, assembled in an assembly line with five stations. Each station is operated by a worker with the tasks in the following Table. Each station/worker works for eight hours a day.

1. If the demand on 11/1 is 800, and the factory wants to complete the demand within 8 hours on the same date, how many workers are required for each station? How can you line balance the line in Table 1? Which station is the bottleneck after the line balancing?

2. Imagine that the assembly line in Table 1 is a machine-paced assembly line: A.What is the span of control for work station four? B. Which of the stations (S/W) is the bottleneck? C. What is the labor content in seconds? D.How many hours are required to complete five hundred products?

3. If the demand of some day is 500, what is the cycle time in second? What is the idle time in second for each S/W? What is the utilization for each S/W? What is the average labor utilization? What is the implied utilization for each S/W? What is the process utilization?

4. If the demand of any given day is two, what is the cycle time in seconds? What is the idle time in second for each S/W? What is the utilization for each S/W? What is the average labor utilization? What is the implied utilization for each S/W? What is the process utilization? (Note: for utilizations, correct the result to 4 decimal places.)
