A methodology for assessing eco-efficiency in logistics networks

Abstract

AND KEYWORDS AbstractRecent literature on sustainable logistics networks points to two important questions: (i) How to spot the preferred solution(s) balancing environmental and business concerns? (ii) How to improve the understanding of the trade-offs between these two dimensions? We posit that a complete exploration of the efficient frontier and trade-offs between profitability and environmental impacts are particularly suitable to answer these two questions. In order to deal with the exponential number of basic efficient points in the frontier, we propose a formulation that performs in exponential time for the number of objective functions only. We illustrate our findings by designing a complex recycling logistics network in Germany. How to improve the understanding of the trade-offs between these two dimensions?

Handling WEEE waste flows: on the effectiveness of producer responsibility in a globalizing world

“…Last but not least, quality standards also in Asia are expected to rise (HbR, personal communication). The viability of high-level closed-loop recovery was proven in our program with SMEs (Appendix 2), but is also mentioned in other studies [13,15,35,36,42,46]. Products involved include office photocopiers, vending machines, electrical motors and compressors, industrial food processing equipment, computer and telecom equipment, airconditioning units, and truck engines.…”

Incorporating the environmental dimension in the assessment of automated warehouses

“…Moreover, data on warehouse environmental impact allows investigating whether the existing trade-off between the economic and environmental dimensions in the broader context of logistics (Quariguasi Frota Neto et al 2009) is also applicable to warehousing solutions.…”

Assessing the economic performance of an environmental sustainable supply chain in reducing environmental externalities

“…As corporations attempt to move toward environmental sustainability, management must extend their efforts to improve environmental practices across their supply chains (Vachon and Klassen, 2008). One of the most important issues in green logistics is how to identify preferred solutions that balance environmental and business concerns (Quariguasi et al, 2009). Previous studies have addressed sustainability in SCM from different perspectives, including green product design , green purchasing and supplier selection (Bai and Sarkis, 2010;Rao, 2002;Kumar et al, 2014), manufacturing (Ilgin and Gupta, 2010), remanufacturing (Mitra and Webster, 2008), reverse logistics (Barker and Zabinsky, 2011), closed-loop logistics (Devika et al, 2014), and supply chain design (Chaabane et al, 2011).…”
