I am currently working on new models and algorithms for some vehicle routing problems, including customer demands, vehicle capacities, pickup and delivery, restocking actions, time windows, variable speed, green routing, smart transportation, etc. Also other combinatorial optimization problems are of my interest, including scheduling, planning, logistics, location, telecommunication, privacy, etc. My expertize area is develop exact and heuristic approaches for solving difficult decision-making problems.
