Use pairwise and first create a total weekly From-To matrix from the table.

Four equal-sized machines are served by an automated guided vehicle (AGV) on a linear bidirectional track, as shown in the figure below. Each machine block is 30 30. The product routine information and required production rate are given in the table \begin{tabular}{|c|c|c|} \hline Product & Processing Sequences & Weekly Production \\ \hline 1 & B D C A C & 300 units \\ \hline 2 & B D A C & 700 units \\ \hline 3 & D B D C A C & 900 units \\ \hline 4 & A B C A & 200 units \\ \hline \end{tabular} Four equal-sized machines are served by an automated guided vehicle (AGV) on a linear bidirectional track, as shown in the figure below.
