Global synchromodal transportation involves the movement of container shipments between inland terminals located in different continents using ships, barges, trains, trucks, or any combination among them through integrated planning at a network level. One challenges faced by global operators is matching accepted with services an transport dynamic and stochastic travel times. The times are unkno...

Stochastic, as well fuzzy uncertainty, can be found in most real-world systems. Considering both types of uncertainties simultaneously makes optimization problems incredibly challenging. In this paper we propose a simheuristic to solve the Time Capacitated Arc Routing Problem (TCARP) when nature travel time either deterministic, stochastic or fuzzy. The main goal is find solution (vehicle route...

This paper studies optimal path problems integrated with the concept of second order stochastic dominance. These problems arise from applications where travelers are concerned with the trade off between the risks associated with random travel time and other travel costs. Risk-averse behavior is embedded by requiring the random travel times on the optimal paths to stochastically dominate that on...

We consider a class of routing optimization problems on networks with deadlines imposed at a subset of nodes, and with uncertain arc travel times. The problems are static in the sense that routing decisions are made prior to the realization of uncertain travel times. The goal is to find optimal routing policies such that arrival times at nodes respect deadlines “as much as possible”. We propose...
