Abstract:
With increasing concerns on environmental issues, recent research on Vehicle Routing Problems

(VRP) has added new factors such as greenhouse gas emissions and alternative fuel vehicles into

the models. In this report, we consider one such promising alternative fuel vehicle, Compressed

Natural Gas (CNG). However, due to the limited number of available fueling stations and small

fuel tank capacity, CNG trucks face several challenges on their way to replacing traditional diesel

trucks. Even though CNG trucks have advantages on less greenhouse gas emissions and cheaper

fuel cost, the detours to the fueling station may increase the total travel distance.

We introduce the CNG Truck Routing Problem with Fueling Stations (CTRPFS) to model

decisions to be made with regards to the vehicle routes including the choice of fueling stations.

Moreover we consider load capacity, fuel tank capacity and the driver’s daily traveling distance

limitation. We develop a Mixed Integer Programming (MIP) model with preprocessing and valid

inequalities to solve the problem optimally. A hybrid heuristic method is also proposed to solve

this problem, which combines an Adaptive Large Neighborhood Search (ALNS) with a local search

and a MIP model.

In the numerical experiments section, we solve a set of small instances to show the efficiency

of our preprocessing and valid inequalities. The optimal values from MIP models are used as

benchmarks to show our ALNS can achieve high quality solutions. We run experiments on large

instances to explore some insights on the number of CNG fueling stations and tank capacities.

Based on the estimation of daily goods delivery data from the Ports of Los Angeles and Long

Beach, we conduct experiments comparing the total traveling distance using CNG trucks with the

current use of diesel trucks for local delivery.
