A netwоrk representаtiоn оf а trаnsportation problem has 2 supply nodes and 3 demand nodes connected by 6 distribution routes. The owner of the logistics company wants to minimize costs to meet the demand. Each origin and destination is represented by a node, and each shipping route by a directed arc indicating the flow of goods from supply to demand locations. In this Ohio-based scenario, the origin nodes are Columbus and Cleveland. The destination nodes are Cincinnati, Toledo, and Dayton. The Columbus node is the starting point of three arrows directed toward Cincinnati, Toledo, and Dayton, with transportation costs per unit of $12, $9, and $8, respectively. The Cleveland node is also the starting point of three arrows directed toward Cincinnati, Toledo, and Dayton, with transportation costs per unit of $10, $6, and $7, respectively. Here is the spreadsheet again in the 4th tab": BANA_II_2026_Spring_Final_Exam-2-5.xlsx Supply Nodes (Origins): Columbus (Supply: 40 units) Cleveland (Supply: 30 units) Demand Nodes (Destinations): Cincinnati (Demand: 25 units) Toledo (Demand: 20 units) Dayton (Demand: 25 units)   Transportation Routes (Arcs with Costs) From Columbus: → Cincinnati ($12) → Toledo ($9) → Dayton ($8) From Cleveland: → Cincinnati ($10) → Toledo ($6) → Dayton ($7)
