The Wisman Candy Company manufactures a variety of candy products. Company trucks are used to deliver local orders directly to retail outlets. When the business was small, the drivers of the truck were free to take routes of their choice as they made the delivery rounds to the retail outlets. However, as the business has grown, transportation and delivery costs have become significant. In an effort to improve the efficiency of the delivery operation, Wisman’s management would like to determine the shortest delivery routes between retail outlets. For example, the following network shows the roads that may be taken between a retail outlet at node 1 and a retail outlet at node 11. Determine the shortest route for a truck that is currently at node 1 and must make a delivery to node 11.
