Use Johnson's rule to determine the optimal sequencing for the five jobs to be processed on two machines in a fixed order (Machine 1 before Machine 2). The processing times are given in the table below.
a. What is the optimal sequence?
b. What is the total flow time for this sequence?
$$\begin{array} { | c | c | c | }
\hline \text { Job } & \text { Machine 1 } & \text { Machine 2 } \
\hline \text { L } & 10 & 11 \
\hline \text { M } & 8 & 17 \
\hline \mathrm { N } & 14 & 9 \
\hline \mathrm { O } & 13 & 7 \
\hline \mathrm { P } & 10 & 8 \
\hline
\end{array}$$
