Research

• I recently finished my PhD, focused on a vehicle routing problem that is called
  
                   Double Traveling Salesman Problem with Multiple Stacks (DTSPMS).
  
  If you want to know more about this problem click here.
   

• I am also working on the Green Vehicle Routing Problem, a version of the VRP with electrical vehicles.
  To download the data sets of the benchmark instances (100, 200 and 400 customers)
  we have used, click here.
   

• Interest areas:

                             Mathematical programming.                        Combinatorial Optimization.   

                                    Vehicle routing problems.                             Metaheuristics.

• I am also working on the Multiple Vehicle Pickup and Delivery Problem with LIFO constraints and Maximum Time (PDPLT). The data instances we are using and the best lower and upper bounds we have found are available here.
