Optimal Urban Logistics Facility Location with Consideration of Truck-Related Greenhouse Gas Emissions: A Case Study of Shenzhen City

الملخص EN

The logistics facility location is always involved with great deals of investment.

Its construction and operation also bring out a huge amount of the greenhouse gas (GHG) emission due to the consumption of building materials, energy, the running of trucks, and other logistics equipment.

Particularly, trucking activities in the urban logistics networks (ULN) are a major source of GHG.

This paper aims to formulate an eco-facility location model to minimize both the total cost of ULN construction and operation and the GHG emissions of truck trips.

Based on the mathematical relations of GHG emissions rates and several macroscopic factors, which we obtained by multivariate regression analysis on a large set of empirical trucking data in our previous research, the data-driven emissions rates estimation function is acquired.

Then, we link the estimation function of each trip purpose by various kinds of logistics facilities through a qualitative analysis.

The eco-facility location problem is modeled by integrating the pure facility location model and the GHG emissions function.

The problem is first converted to a biobjective mixed-integer program, and the Particle Swarm Optimization algorithm is applied to solve the model.

Through experiments with real case, the effectiveness of the models and algorithms is verified.

The eco-facility location model for ULN tends to obtain the environment-friendly location decision.

Our analytical results also verify the hypothesis that locations of facility do impact the relevant truck-related GHG emissions, especially to transfer transport, as well as inbound and outbound freight.
