Because some of the roads are highways and others are city streets, the shortest-distance routes between the office and the construction site may not necessarily provide the quickest or shortest-time route. Shown here is the Gorman road network with travel time rather than distance. Find the shortest route from Gorman’s office to the construction site at node 6 if the objective is to minimize travel time rather than distance.The FAA has granted a license to a new airline, Omniair, and awarded it several routes between Los Angeles and Chicago. The flights per day for each route are shown in the following network: Determine the maximum number of flights the airline can schedule per day from Chicago to Los Angeles and indicate the number of flights along each route.
- Abu Dhabi municipality is given an assignment to ensure provision of enough water for residents of the Abu Dhabi city. The water is purified in a large water treatment plant (node 1) and then is sent via a water supply network to the Abu Dhabi city (node 14). As shown in the below water supply network, the capacity of each water pipeline (arc) is shown in million liters per hour. For example, the hourly water flow from node 1 to node 2 is four million liters, and from node 2 to node 1 is zero million liters. a) The municipality is interested to find out how much water (in million liters per hour) can be sent from the water treatment plant to the Abu Dhabi city via this water supply network. Determine it. b) Due to a maintenance problem both nodes 10 and 11 need to be taken offline. Therefore, these nodes cannot flow any water in and out. How this problem impacts the network maximum flow capacity? Please include algebraic method and excel solver.The Thor International Company operates four factories that ship products to five warehouses.
