Short Answer

Given the following data for jobs awaiting processing at a manufacturing cell in which jobs are first processed by machine A, then by machine B:
$$\begin{array} { c } \quad\quad\quad{ \text { Process Time (Hours) } } \\\begin{array} { l c c } \text { Job } & \text { Center A } & \text { Center B } \\\hline \mathrm { W } & 4 & 5 \\\mathrm { X } & 6 & 6 \\\mathrm { Y } & 1 & 2 \\\mathrm { Z } & 5 & 2\end{array}\end{array}$$ What is the sequence which will minimize throughput time?
