  1. Optimization in public transportation José Fernando RománGuzmán 11/28/12

  2. The System: Transmilenio

  3. “Tables”

  4. The Problem • Kilometers assign to each company is equal to the participation times the total kilometers of all the “tables”. • Assign all of the “tables” to the seven companies according to their participation • Minimize the hlp

  5. Restrictions • Limited capacity in the parking lots • Different type of buses • Special requirement form the companies

  6. The Solution • Linear Optimization using the simplex algorithm to find the real solution and then the branch and bound algorithm to find the integer solution • Only one person is responsible for the assignation of whole system • Reduction of the HLP(kilometers when the buses are not in service) of 25%
