Assume you plan to make boxes together with three classmates and each of you is assigned to exactly one task (A-D).

We will not make lids for the boxes this time.

Then the stages to make a box should be (in this order)

A: Fold horizontially and vertically, unfold,

B: Fold four corners,

C: Fold sides to center,

D: Unfold two sides and reverse fold them to finish.

Assume the following amount of work in seconds is required at each station:

A: 32 secs, B: 30 secs, C: 43 secs, and D: 62 secs.

(Assume you want to make many boxes, i.e., perform the calculations for a continuous process.)

Additional Information:

Additionally, your brother/sister/friend wants to know what you are doing and is happy to join in.

1 - With this additional helper, what is the new flow time (from plain paper to finished box)? Please give your answer in seconds.

2 - What is the new bottleneck stage? What is the capacity rate of your process (boxes per hour)? Please round to 4 decimal places.

3 - What is the cycle time of your process? Please give your answer in seconds.

4 - What is the simple average of the utilization of your resources? Please express the answer in form of a decimal between 0 and 1 (keeping at least 4 decimal places).
