Answer:
We need 4 workstations configurated in series as minimum to create theoretically a finished product every 3 minutes.
Step-by-step explanation:
At first we assume that assembly line is formed solely by workstations configurated in series. We must keep in mind that theoretical minimum number of workstations is equal to the sum of the task times required to create a product divided by the time taken by the assembly line to create one finished product. That is:
[tex]n = \frac{700\,s}{3\,min\times 60\,\frac{s}{min} }[/tex]
[tex]n = 3.889\,workstations[/tex]
We need 4 workstations configurated in series as minimum to create theoretically a finished product every 3 minutes.
