$*$what does the precedence diagram look like and how do I find out the idle time for the assembly line for a $10$ min cycle$*$ Dr$.$ Lori Baker, operations manager at Nesa Electronics, prides herself on excellent assembly$-$line balancing. She has been told that the firm needs to complete $96$ instruments per $24-$hour day. The assembly$-$line activities are:

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

b$)$ For the given daily $(24-$hour$)$ production rate of $96$ units, the highest allowable cycle time $=15$ minutes $($enter your response as a whole number$).$

c$)$ If the cycle time after allowances is given as $10$ minutes, then the effective daily $(24-$hour$)$ production rate $=144$ units $($enter your response as a whole number$).$

d$)$ For the given $10-$minute cycle time after allowances, the theoretical minimum number of workstations $=($round your response up to the next whole number$).$

e$)$ Using the longest assigned task time of all of the workstations and $6$ workstations, the operating efficiency of the assembly line $=93\mathrm{.}33\%($enter your response as a percentage rounded to two decimal places$).$

f$)$ Using the $10-$minute cycle time after allowances and $6$ workstations, the idle time for the assembly line per cycle $=$ minutes $($enter your response as a whole number$).$
