This exercise only contains parts $b,c,d,e,$ and $f.$

b$)$ Given the demand, the cycle time for the production of the new train set $=31\mathrm{.}3$ seconds $($round your response to one decimal place$).$

c$)$ The theoretical minimum number of workstations $=4($round your response up to the next whole number$).$

d$)$ Using the longest operation time rule, the assignment of tasks to workstations should be: $($Hint: Number workstations sequentially in terms of precedence relationships and combine any applicable tasks.$)$

Were you able to assign all the tasks to the theoretical minimum number of workstations? No

e$)$ The total idle time per cycle for the process $=31$ seconds $($enter your response as a whole number$).$

f$)$ The efficiency of the assembly line with $5$ workstations $=\%($enter your response as a percentage rounded to one decimal place$).$
