Peaches are to be transported from three orchard regions to two canneries. Intermediate stops at a consolidation station are possible. $$\begin{array} { | l | c | l | l | c | } \hline \text { Orchard } & \text { Supply } & \text { Station } & \text { Cannery } & \text { Capacity } \\\hline \text { Riverside } & 1200 & \text { Waterford } & \text { Sanderson } & 2500 \\\hline \text { Sunny Slope } & 1500 & \text { Northside } & \text { Millville } & 3000 \\\hline \text { Old Farm } & 2000 & & & \\\hline\end{array}$$ Shipment costs are shown in the table below. Where no cost is given, shipments are not possible. Where costs are shown, shipments are possible in either direction. Draw the network model for this problem. $$\begin{array} { | l | c | c | c | c | c | c | c | } \hline & \mathrm { R } & \text { SS } & \mathrm { OF } & \mathrm { W } & \mathrm { N } & \mathrm { S } & \mathrm { M } \\\hline \text { Riverside } & & 1 & & 5 & & 3 & \\\hline \text { Sunny Side } & & & & 4 & 5 & & \\\hline \text { Old Farm } & & & & 6 & 3 & & \\\hline \text { Waterford } & & & & & 2 & 2 & 4 \\\hline \text { Northside } & & & & & & 5 & 9 \\\hline \text { Sanderson } & & & & & & & 2 \\\hline \text { Millville } & & & & & & & \\\hline\end{array}$$
