Aquino, R.; Baran, B.; Lopez-Pires, F.; Sandoya, F.; Chicaiza, J.: A Novel Multi-Objective Two-Echelon Green Location-Routing Problem from a City Government Perspective. Congreso Internacional de Ciencias de la Computación y Sistemas de Información (CICCSI 2017), Mendoza, (Argentina,) 13-17 November 2017.

This work presents a novel two-echelon, multi-product, Green Location-Routing Problem formulation from a city government perspective, for the optimization of five objective functions, two of them related to pollutant emissions minimization. Additionally, it is demonstrated that the use of city distribution centers (CDCs), compared to direct shipping, is a better strategy for a congested city as Asunción in Paraguay. Initial experimental results using an exhaustive search alternative prove an 8-23% reduction of carbon monoxide (CO) emissions, a 6-22% reduction of carbon dioxide (CO2) emissions and an 8-17% reduction in shipping costs, given an initial investment in CDCs.
