Starting from a real-life application, in this short paper, we propose the original Multi-Depot Multi-Trip Vehicle Routing Problem with Total Completion Times minimization (MDMT-VRP-TCT).

It is worth noting that this problem is original as in the literature its characteristics (i.e., multi-depot, multi-trip and total completion time) can be found separately, but never all together.

Abstract
Starting from a real-life application, in this short paper, we propose the original Multi-Depot Multi-Trip Vehicle Routing Problem with Total Completion Times minimization (MDMT-VRP-TCT). For it, we propose a mathematical formulation as a MILP, design a matheuristic framework to quickly solve it, and experimentally test its performance. It is worth noting that this problem is original as in the literature its characteristics (i.e., multi-depot, multi-trip and total completion time) can be found separately, but never all together. Moreover, regardless of the application, our solution works in any case in which a multi-depot multi-trip vehicle routing problem must be solved.
