The operations manager of a body and paint shop has five cars to schedule for repair. He would like to minimize the throughput time to complete all work on these cars. Each car requires body work prior to painting. The estimates of the times required to do the body paint work on each are as follows: $$\begin{array} { l c c }
\text { Car } & \begin{array} { c }
\text { Body Work } \
\text { (hrs) }
\end{array} & \begin{array} { c }
\text { Paint } \
\text { (hrs) }
\end{array} \
\hline \text { A } & 10 & 2 \
\text { B } & 5 & 4 \
\text { C } & 7 & 5 \
\text { D } & 3 & 6 \
\text { E } & 1 & 7
\end{array}$$ Where in the optimum sequence should car E be scheduled?
A) first
B) second
C) third
D) fourth
E) fifth

To minimize the throughput time, we need to schedule the cars in order of decreasing body work time. This is because we want to get the cars which require more time to be done first, so they can get started earlier. Based on this criterion, we should schedule the cars in the following order: A, C, B, D, E. This means that Car E should be scheduled first.
