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.

PharmaCo wants to determine how to deploy sales representatives across its Western U.S. region to support a new drug for obesity. Sales representatives will be located in a "home city", which they serve, in addition to cities with feasible commuting distance, with the objective that all cities must be served by at least one sales representative. The feasible connections between each city in the region are listed below (1 indicates a feasible connection, potential home cities are shown in columns, and cities served in rows): Potential Rep Home City Served?

A rapidly expanding company is looking to lease a small plant in Memphis, Tennessee, Biloxi, Mississippi, or Birmingham, Alabama. Prepare a cost benefit study for each of the three locations using the following data: The annual construction, facilities, and administration expenses for Memphis, Biloxi, and Birmingham will be $40,000, $60,000, and $100,000, respectively. In Memphis, labour and materials are estimated to cost $8 per month, $4 in Biloxi, and $5 in Birmingham. The Memphis site would add $50,000 a year to device transportation expenses, the Biloxi location would add $60,000 per year, and the Birmingham location would add $25,000 per year. The annual production is expected to be 10,000 units.

Determine the shortest route from Atlanta to each of the other five cities in the network. B. Assume that the network now represents six different communities in a city and that the local transportation authority wants to design a rail system that will connect all six communities with the minimum amount of track. The miles between each community are shown on each branch. Develop a minimal spanning tree for this problem.
