This paper studies an unmanned aerial vehicle (UAV)-assisted wireless network, where a UAV is dispatched to gather information from ground sensor nodes (SN) and transfer the collected data depot. The freshness captured by age of (AoI) metric, whilst energy consumption seen as another performance criterion. Most importantly, AoI efficiency are inherently competing metrics, since decreasing requi...

This paper studies the distribution of emergency relief for electric vehicles (EVs), which considers energy saving, multi-depot, and vehicle routing problems with time windows, named saving-oriented multi-depot problem windows (ESMDVRPTW). Our aim is to find routes EVs such that all shelter demands are fulfilled during their total cost traveled by fleet minimized. To this end, we formulate ESMD...

In this work, the Multi-Depot Green VRP with Pickups and Deliveries (MDGVRP-PD) is studied. It a routing optimization problem in which objective to construct set of vehicle routes considering multiple depots one-to-one pickup delivery operations that minimize emissions through fuel consumption, depends on weight travel distance. problems, goods must be transported between single origin its asso...

This paper presents a method for solving the multi-depot location-routing problem (MDLRP). Since several unrealistic assumptions, such as homogeneous #eet type and unlimited number of available vehicles, are typically made concerning this problem, a mathematical formulation is given in which these assumptions are relaxed. Since the inherent complexity of the LRP problem makes it impossible to s...

The fixed destination multi-depot multiple traveling salesmen problem (MmTSP) is a problem, in which more than one salesmen depart from several starting cities and having returned to the starting city, form tours so that each city is visited with exactly one salesman, and the tour lengths stay within certain limits. This problem is of a great complexity and few investigations have been done on ...
