It takes 16 activities to assemble a telescopic umbrella. The total amount of time to finish all 16 activities by a single assembly worker is 1 hour and 20 minutes. Examples of the activities include:

- Installing a center spring in the shaft, which takes 3 minutes and 50 seconds.

- Spreading the canopy over the ribs: 2 minutes and 45 seconds

- Attaching stretchers to the ribs and the runner: 4 minutes and 5 seconds

- Placing the ferrule on the tip of the umbrella: 25 seconds.

- Other activities, such as attaching the crook handle, mounting the bottom and top springs, etc., that each take different amounts of time ranging from 30 seconds to 4 minutes 12 seconds.

The umbrella assembly line operates for 7 hours per day.

8.2.1 What are the minimum and maximum cycle times?

8.2.2 What daily output rate will be achieved by each of those cycle times (i.e. the minimum and maximum)?

8.2.3 Now suppose the line is balanced using 5 workers, the total tasks time of each is the following:

Worker A: 15 minutes and 12 seconds

Worker B: 16 minutes and 48 seconds

Worker C: 17 minutes and 30 seconds

Worker D: 15 minutes and 50 seconds

Worker E: 14 minutes and 40 seconds

What is the output rate (actual throughput in umbrellas per workday) and what is the assembly line efficiency?
