Incorporating the environmental dimension in the assessment of automated warehouses

Abstract

In today's competitive context, the paradigm of sustainable development is becoming more and more significant, also in warehousing. Managers are progressively considering not only purely economic aspects but also environmental concerns. Despite such consciousness, the selection of automated warehousing solutions has been mainly based on operational and economic performance in both practice and theory so far, whereas energy consumption and environmental performance have not been adequately taken into account. To fill this lack a model is proposed to evaluate the energy consumption and environmental impact of automated warehousing solutions. The model has been used to investigate whether the selection of automated solutions changes varying the dimensions involved in the analysis (i.e. only economic, only environmental or both). The analysis has been performed considering autonomous vehicle storage and retrieval systems (AVS/RSs) and its natural alternative, i.e. automated storage and retrieval systems (AS/RSs). Results confirm the importance of considering both dimensions in the assessment of automated warehouses, as depending on the scenario the technology selection shifts from AS/RS to AVS/RS when considering not only the economic but also the environmental impact. Additionally, this study provides new insights on the suitability areas of AVS/RSs.

Sustainability Assessment of logistics activities in a dairy: An example of an emerging economy

“…Many methods assess the logistics activities impacts only on the environmental dimension (e.g., Palander (2017)). Others simultaneously evaluate the economic and environmental impacts of logistics activities (e.g., Tappia et al (2015)). The method of Tan et al (2010) assesses the impacts of a logistics activity on the three dimensions of sustainability.…”

Multi-directional local search for sustainable supply chain network design

“…Warehouses have significant amount of energy consumption due to lighting, heating, cooling and air condi-95 tioning as well as material handling equipment (Ries et al, 2017). Environmental assessment becomes particularly crucial in automated warehouses (Tappia et al, 2015). "…”

A Critical Comparison of Alternative Distribution Configurations in Omni-Channel Retailing in Terms of Cost and Greenhouse Gas Emissions

“…For instance, Colicchia et al [18] proposed a supply chain network design framework that is based on multi-objective mathematical programming to identify 'eco-efficient' configuration alternatives (defined by the number of transit points to be activated) that are both efficient and ecologically sound. A comparison among different warehousing automated solutions were provided by [19], including the environmental dimensions starting from the energy consumption evaluation. In most cases, these contributions used conversion factors to estimate CO 2 emissions starting from the energy consumption or the number of travelled kilometres based on specific books and reports provided by a government agency (e.g., [20,21]).…”
