Transportation Resource Management in Large-scale Freight Consolidation Networks

ACKNOWLEDGEMENTS Completing this dissertation has been quite a journey! It has brought me immense professional and personal growth and a plethora of experiences that I will fondly remember. I am very grateful to have worked with Alan Erera and Martin Savelsbergh. They have been exceptional advisors who guided, motivated, and supported me to develop as a researcher and make this dissertation pos...

Vehicle routing with stochastic time-dependent travel times

Assigning and scheduling vehicle routes in a stochastic timedependent environment is a crucial management problem. The assumption that in a real-life environment everything goes according to an a priori determined static schedule is unrealistic. Our methodology builds on earlier work in which the traffic congestion is captured based on queueing theory in an analytical way and applied to the V R...

The time-dependent vehicle routing problem with soft time windows and stochastic travel times

This paper studies a vehicle routing problem with time-dependent and stochastic travel times. In our problem setting, customers have soft time windows. A mathematical model is used in which both efficiency for service as well as reliability for customers are taken into account. Depending on whether service times are included or not, we consider two versions of this problem. Two metaheuristics a...

Ambulance location and relocation problems with time-dependent travel times

EMERGENCY SERVICE PROVIDERS ARE FACING THE FOLLOWING PROBLEM: how and where to locate vehicles in order to cover potential future demand effectively. Ambulances are supposed to be located at designated locations such that in case of an emergency the patients can be reached in a time-efficient manner. A patient is said to be covered by a vehicle if (s)he can be reached by an ambulance within a p...
