Special Issue Information

Dear Colleagues,

Energy efficiency has been largely neglected in supply chain and logistics. The production and logistics processes are usually seen as independent entities in which the objective of improving energy efficiency is targeted at the level of single companies. However, this myopic approach does not allow to fully discover the benefits achievable with energy efficiency with an assessment at the system level. Supply chains are a system of organizations, people, activities, and information that transform natural resources, raw materials, and components into finished products for consumers.

Measuring energy consumption of all supply chain actors makes it possible to identify the most energy consuming parts of the supply chain and also to detect the most influential decision-making steps of the supply chain, thus providing information for the assessment of energy saving potential. The ability to measure and to benchmark energy efficiency at the supply chain level is a prerequisite for the implementation and planning of energy efficiency measures in logistics.

Moreover, the availability of alternative logistics configuration offered by modern transportation equipment and warehousing technologies may allow to reduce consistently the energy impact of these activities.

Supply chain management can lead to increased opportunities for energy efficiency improvement and represents the major opportunity in overcoming the barriers of implementing energy efficiency measures. Since supply chain considers the product from initial processing of raw materials to the delivery to the customer, the holistic approach can ensure sustainability, thereby also satisfying customer needs for environmental-friendly end products.

Moreover, considering energy efficiency of the supply chains requires considerable rethinking on the strategic level (supply and distribution network design, supplier selection) as well as at the operational level (logistics decisions on inventory policies, lot sizing, shipment batch size).

By working closely with customers and suppliers, companies can reduce the energy impact and improve the economic results. Most companies still pay relatively minor attention to whether their suppliers apply energy management systems in their business activities; however, it is important to acknowledge the potential influence that supply chain interactions may have on improving energy efficiency as well as the environmental impacts and costs of the final products.

A stronger cooperation among the supply chain members and the implementation of the holistic approach, in which the point of view is shifted from the single company to the system, lead to the achievement of a global optimum instead of a local one.

Energy efficiency and environmental issues have been largely neglected in logistics. In a traditional supply chain, the objective of improving energy efficiency is targeted at the level of single parts of the value making chain. Industry 4.0 technologies make it possible to build hyperconnected logistic solutions, where the objective of decreasing energy consumption and economic footprint is targeted at the global level. The problems of energy efficiency are especially relevant in first mile and last mile delivery logistics, where deliveries are composed of individual orders and each order must be picked up and delivered at different locations. Within the frame of this paper, the author describes a real-time scheduling optimization model focusing on energy efficiency of the operation. After a systematic literature review, this paper introduces a mathematical model of last mile delivery problems including scheduling and assignment problems. The objective of the model is to determine the optimal assignment and scheduling for each order so as to minimize energy consumption, which allows to improve energy efficiency. Next, a black hole optimization-based heuristic is described, whose performance is validated with different benchmark functions. The scenario analysis validates the model and evaluates its performance to increase energy efficiency in last mile logistics. Full article

In the industrial food supply chain, cold storage is one of the most important processes where there is a huge but still unused potential for employing renewable energy technologies. This paper analyses how the integration of rooftop photovoltaics affects the design and performance of refrigerated automated warehouses, which are becoming the preferred choice for frozen food storage facilities. The problem is modelled and solved by means of Constraint Programming. Results for the reference case in north-eastern Italy show that photovoltaic installation can lead to both yearly total cost and energy savings. Simulations highlight how design and performance of the refrigerated automated warehouse strictly depend on supply chain decision variables. PV integration offers supply chain managers more opportunities to act on the storage temperature and the incoming product temperatures strictly related to upstream and downstream stages of the whole cold chain. Attention should be paid to system throughput, which presents an intermediate range for which the design optimization of volume and surfaces reduces the convenience of PV integration. Simulations on facility locations reveal how different climate conditions affect the economic and environmental performance of the refrigerated warehouse, as well as country specific carbon intensity and energy price.

Attention to energy efficiency is recently experiencing substantial growth. To overcome the several barriers currently existing that represent an obstacle to the successful implementation of the wide set of energy efficiency measures available, the cooperation among members of a supply chain offers a huge potential. In supply chains, in addition to the traditional coordination of the operations, the members may also share financial resources or act jointly on the capital market. This study presents a two-stage supply chain model considering the opportunity to invest in new energy efficient technologies which are affected by learning effects: the member of the supply chain with better energy performance and/or better financial conditions may find it more profitable to invest in the development of the energy efficiency of its partner. The objective of the model is to determine the optimal investment for each supply chain member so as to maximize the Net Present Value of the supply chain. The impacts of the proposed joint decision-making are investigated through some numerical analysis and managerial insights are proposed: the joint decision-making process on the financial flows for the energy efficiency investments results are especially advantageous (up to a 20% increase of the supply chain Net Present Value) when members have different access to capital, which could be the result of different economic conditions in companies’ countries, as well as different credit policies or different credit ratings.

Energy efficiency represents a key resource for economic and social development, providing substantial benefits to different stakeholders, ranging from the entities which develop energy efficient measures to everyone in society. In addition to cost savings, multiple benefits can be achieved by supporting a better alignment between energy issues and strategic business priorities: e.g., improved competitiveness, profitability, quality, etc. Thus, energy efficiency can be a strategic advantage, not just a marginal issue, for companies. However, most firms, especially small and medium enterprises (SMEs), face many problems and, in some cases, hostility when trying to effectively implement energy efficiency actions. The most dominant barriers are the access to capital and the lack of awareness (especially in terms of life cycle cost effects). The supply chain viewpoint represents one of the main opportunities for overcoming those barriers and improving energy performance even for weaker companies. Since the current literature on energy efficiency and practical approaches to ensure energy efficiency mainly focus on energy performance on a single-firm basis, this paper aims to provide a systematic review of papers on the integration of energy efficiency in supply chain design and management published in academic journal, thereby defining potential research streams to close the gaps in the literature. A number of literature reviews have been published focusing on specific aspects of sustainable or on green supply chain management; however, to the best of our knowledge, no review has focused on the energy efficiency issue. Firstly, the present paper shows how considering energy consumption in supply chain management can contribute to more energy-efficient processes from a systemic point of view. Then, the review methodology used is defined and the sampled papers are analyzed and categorized based on the different approaches they propose. From these analyses, potential future research streams are outlined. Full article
