    <description>Title: Alternative fuels in road freight transport: Objectives and scope of a literature review
Authors: Meyer, Maeva; Bousonville, Thomas
Abstract: This literature review investigates alternative solutions to fossil fuels in the context of road freight transport, focusing on both ecological and economic perspectives. A rigorous bibliographic method- ology was employed to ensure the relevance and quality of the selected studies. The research process was structured through a systematic, multi-step decision-making approach, which included selecting the most appropriate research plat-form, identifying a relevant keyword combination, and deciding whether to search for keywords in abstracts only or across the entire text. Through this process, 157 scientific publications were identified as relevant for further analysis. The present document focuses on the methodology used to collect, select, and classify the relevant literature.</description>

    <description>Title: Bedarfsanalyse zum Aufbau eines Food Co-Working Space für die Verarbeitung regionaler Lebensmittel(überschüsse) im Saarland
Authors: Hein, Nika; Melo, Teresa
Abstract: Lebensmittelverschwendung stellt weltweit und auch in Deutschland ein großes Problem dar. Neben den wirtschaftlichen und ethischen Folgen tragen Lebensmittelüberschüsse auch zu Umweltbelastungen bei. In den letzten Jahren sind zahlreiche Initiativen entstanden, um das Bewusstsein für dieses Thema zu schärfen und Lebensmittelverluste zu reduzieren. Die Einrichtung eines Food Co-Working Space ist eine Möglichkeit, um regionale Lebensmittel zu verarbeiten und somit der Lebensmittelverschwendung entgegenzuwirken. Mittels einer Online-Umfrage und Experteninterviews wird in der vorliegenden Studie der Bedarf zum Aufbau eines Food Co-Working Space im Saarland untersucht. Basierend auf den Antworten konnte festgestellt werden, dass für die Etablierung eines solchen Geschäftsmodells im saarländischen Raum das Interesse derzeit noch nicht ausgeprägt genug ist. Dennoch konnten anhand der Analyse einige Bedarfe identifiziert werden, auf deren Grundlage ein Ausblick auf mögliche Konzepte geboten wird.</description>

    <description>Title: Modeling and solving a dynamic logistics network design problem with temporary capacity expansion and reduction
Authors: Correia, Isabel; Melo, Teresa
Abstract: This study addresses a two-echelon network design problem that determines the location and size of new warehouses, the removal of company-owned warehouses, the inventory levels of multiple products at the warehouses, and the assignment of suppliers as well as customers to warehouses over a multi-period planning horizon. A distinctive feature of our problem is that new warehouses operate with modular capacities that can be expanded or reduced over several periods, the latter not necessarily having to be consecutive. Moreover, in every period, the demand of a customer for a given product has to be satisfied by a single warehouse. This problem arises in the context of warehousing-as-a-service, a business scheme that offers flexible conditions for temporary capacity leasing. The associated fixed warehouse lease cost reflects economies of scale in the capacity size and the length of the lease contract. We develop a mixed-integer linear programming formulation and propose a matheuristic to solve this problem, which exploits the structure of the optimal solution of the linear relaxation to successively assign customers to open warehouses and fix other binary variables related to warehouse operation. Additional variable fixing rules are also developed, based on a scheme for managing inventories at warehouses and using the quantities provided by suppliers. Numerical experiments with randomly generated large-sized instances reveal that the proposed matheuristic outperforms a general-purpose solver in 74% of the instances by identifying higher quality solutions in a substantially shorter computing time.</description>

    <description>Title: The impact of flexible warehouse lease contracts on the configuration of a two-echelon distribution network
Authors: Correia, Isabel; Melo, Teresa
Abstract: E-commerce has experienced a remarkable growth in recent years. This trend is gradually driving retailers to shift from typical warehouse rental contracts with rigid conditions and long-term commitments to flexible alternatives that provide storage space on demand. This strategy gives retailers the ability to respond dynamically to variations in demand, thereby improving customer service. In this paper, we address this trend by considering a two-echelon, multi-commodity distribution network operated by a retailer and whose configuration can be changed over a multi-period planning horizon. Location decisions concern the intermediate facilities and are framed by flexible and scalable conditions. Accordingly, the retailer needs to decide which company-owned facilities should be retained, and where, when and for how long new facilities should be leased from a set of potential sites with given capacities. In this setting, a facility can be leased at the same location for several non-consecutive periods. In addition to location decisions, also procurement, inventory, and distribution decisions need to be made to satisfy customer demand at minimum total cost. We develop a mixed-integer linear programming formulation for this problem and propose various families of additional inequalities that prove to be very useful to find high-quality solutions. To measure the impact of the new business model, we also consider alternative approaches with limited flexibility and scalability that are frequently encountered in practice. Our computational study gives useful insights on the trade-offs achieved by each of the different approaches with respect to total cost, network redesign decisions, and various logistics functions.</description>
