Mathematical Models of Transportation Systems and Networks

2016/7/5 10am-12am, 1:30pm-3:30pm

(Room 1501 of Bldg. E2)

This short course covers selected topics in mathematical models arising in the analysis of transportation systems and networks. We will briefly review basic topics in network optimization and then will proceed to commonly used models for logistics service planning by private companies as well as management of public vehicular infrastructure. This course will cover topics such as risk-averse routing, vehicle routing problems, network user equilibrium, road pricing and network design, location problems, and modeling drivers’ decision making processes, with applications in bike-sharing services, electric-vehicle charging, hazardous materials transportation, and congestion mitigation. This course will also introduce some computational tools available in the Julia Language.Outline (subject to change)
