The objective of the transportation problem is to minimize the total cost of shipments, which is expressed the sum of the products shipment costs and amounts form the warehouses to the cities as follows. How would you modify the Transportation Excel file that we used in the class to find a good solution to the problem? Can you come up with a good heuristic (rule of thumb) to find a good solution to this problem? Implement your solution in EXCEL...

Which of the following statements is false? A transshipment problem is a generalization of the transportation problem in which certain nodes are neither supply nodes nor destination nodes. The assignment problem is a special case of the transportation problem in which all supply and demand values equal one. The objective of the transportation problem is to minimize the number of shipments necessary to satisfy total demand at the destinations. Converting a transportation problem linear programming from profit maximization to cost...

Problem 2 A transportation network is shown in the attached figure. Perform traffic assignment for a demand of 3000 vehicles from zone 3 to zone 5 as follows: (1) Find the shortest path between these two zones using the minimum path algorithm discussed in class, and assign 50% of the traffic to the path. (2) Update the travel time for each links with a traffic load by a factor of 1.2 (ie, 20% increase) and assign another 50% of the...

General Ford produces cars at Malatya and Antalya and has a warehouse in Eskisehir; the company supplies cars to customers in Ankara and Istanbul. The cost of shipping a car between points is given in the table below. (-" means that a shipment is not allowed). Malatya can produce as many as 1,300 cars, and Antalya can produce as many as 1,900 cars. Ankara...
