I only need the theoretical efficiency with steps.

handle 40-mph winds and seas over 10 foot. The final assembly plant is in Cupertino, Califomia. At this ime, 300 minutes aro valablo oach day to manufacturo Mach 10. The daly demand 60 boat. Given t folowing iformation: Fig Task Time (mins D, E,F Fig. G, H ) The correct precedence relationship with one of the posible aigrment of tasks to workstations is shown in Fig 3 The operating efficiency of the assembly line with 3 workstations shown in the figue chosen above. % (arter your response as a percentage rounded to one decimal plece) The theoretical minimum number of workstations 3 (round your response up to the next whoe The idle time for the ansembly line per cycle 1 minutels) (onter your response as a whole number) c) If 400 minutes were available, the theoretical minimum number of workstations Fig up to the next whole numbe) The theoretical officiency (using the cycle time based on 400 minutes available during the day and the theoretical %(enter your response as a percenta eronded to one deci nal peace minimum number of workstations) would

Explanation / Answer

I assume only answer to second part of (c) is required to be answered.

Since new available time is 400 minutes per day and the demand is 60 boats( As read from the question), the new cycle time is:

Cycle time = 400/60 = 6.67 Minutes/Unit.

Also, as per the given data in table, total work element time = 1+1+3+1+3+1+1+2+1 = 14 minutes/unit

Therefore, theoretical efficiency in this case = Total Work element time/(Theoretical minimum Number of workstations*cycle time) = (14/(3* 6.67))*100 = 69.96% ~ 70.0 %
