Abstract
Green Location and Routing Problems extend the network design problems that
consider location and routing decisions by explicitly accounting environmental
impacts such as CO2 emissions caused by fuel or energy consumption of delivery
vehicles. These environmental impacts estimated by fuel or energy consumption
models are a ected by several factors including payload and speed of delivery
vehicles. We present four new green location and routing problems where we
consider these factors while calculating the environmental impacts. We rst introduce
the Green Location-Routing Problem, in which vehicle payload and speed
decisions are incorporated to a location-routing problem and the fuel consumption
of trucks is estimated and minimized. Second, we study the Green Hub Location
Problem, where we minimize the fuel consumption by optimizing truck payload
and speed decisions on a hub network. Third, we present a freight transportation
problem called the Drone Delivery Problem, where the integration of trucks and
drones is used to make deliveries. Drone speed is considered as a decision of the
problem in order to minimize energy consumption of drones while not exceeding
the drone range. Fourth, we study an extension of the Drone Delivery Problem,
called the Stochastic Drone Delivery Problem, where uncertainty of wind speed
and its impact on the drone speed are considered.
