The Theory and Practice of Sustainable Supply Chains

Supply chains have been a concern for organizations since the early periods of the industrial revolution (Sarkis et al., 2011). Supply chain management as a research field is a more recent phenomenon. It has gained increasing importance as outsourcing and globalization have taken on greater roles. Supply chains are also facing immediate and long-term concerns about sustainability and sustainable development. Much of this concern has derived from pressures from industrial, regulatory, consumer, and community stakeholders.

What is the impact of sustainable development on the re-localisation of manufacturing enterprises?

Rendering the supply chain more eco-friendly is an innovative idea progressively adopted by industry. Our research focuses on the CO2 equivalent emissions along the supply chain due to freight energy use and storage. A supply chain model based on discrete event simulation was developed. The model uses reorder point production management policy (ROP) within a make to stock (MTS) demand response strategy. Manufacturing capability is also taken into account using an overall equipment effectiveness indicator (OEE). In addition, the location of the firms and their types of products are modelled. The purpose is to compare supply chain CO2 equivalent emissions of different configurations. This method is applied to two industrial cases: Carrier (UTC group), a large cooler manufacturer and Zannier group, a textile industry. The principle objective of the study is to conduct pertinent experiments to give green guidelines to Carrier and Zannier group.

The ConWip production control system: a systematic review and classification

In the past decade, a growing body of literature has investigated the CONstant Work In Progress (ConWip) production control system (PCS). In view of the current industrial challenges entailing adaptability, product customisation, decreasing leadtimes and customer satisfaction, ConWip seems to be an effective and adaptive PCS for manufacturers. This paper aims to update the last ConWip systematic review that dates back to 2003 and to provide a guide for understanding through an original classification method. This method enables the differentiation of papers that concentrate on ConWip sizing, performance and context as well as a comparison with other PCSs. In addition to providing a key to interpreting the research approaches, the criteria considered answers questions on how to implement, how to optimise and why and when to use ConWip. Finally, the most relevant research avenues are highlighted to provide future lines of research.

Estimating the carbon footprint of a road freight firm, perspectives to mitigate these emissions

Make supply chain greener and reduce their carbon emissions is a growing issue for businesses. Among the different activities of supply chains, transportation is one that emits the most greenhouse gases. Whereas transportation, and more specifically road freight, is one of the main contributors of European greenhouse gases emissions, it is one of the only sector whose emissions continue to growth. This paper proposes a study at a micro-economic scale of the estimation of the carbon footprint of a road freight company in 2009. The main objectives are twofold: identifying the main emissions sources and finding the best solutions for a greener supply chains.

A sustainable maritime balanced scorecard applied to the Egyptian Port of Alexandria

ABSTRACT The multifaceted systems of seaports and the activities around them generate major environmental impacts. Green management objectives and goals are thus of great importance. The main aim of this study is to develop a sustainable maritime balanced scorecard taking into account economic, social, and environmental indicators. We examine the environmental management strategies that can reduce the ecological footprint in the case of the Port of Alexandria and identify the most significant environmental aspects of this seaport. Applying a sustainable maritime balanced scorecard and structural equation modelling, we show that the Port of Alexandria could reduce its gas emissions by implementing a more environmentally, socially, and economically friendly approach to port operations over the long run.

Generic Routings for ConWip Sizing in a Multi-product Environment

In a vulnerable, uncertain, complex, and ambiguous environment, ConWip provides a sustainable, effective and adaptive production control system for manufacturers. The present paper deals with the key questions related to the implementation of ConWip in a high product mix and/or high routing mix environment. To respond to this challenge, generic routing has to be defined to cover all of the routings of the high product mix. Through four algorithms, this paper studies how to define a representative routing. A numerical sample is derived from industrial data. We implement it in the four algorithms to generate four different generic routings. Then, thanks to Wipsim, an engineering tool used in projects to design and improve ConWip lines, we calculate the optimized ConWip parameters for each of them. Finally, we compare the results and highlight some research avenues.

Où en est la logistique inverse dans le secteur aéronautique

RÉSUMÉ La croissance du trafic aérien mondial supérieure à 4% par an dope le secteur de l’aéronautique. L’éco-conception des avions se généralise mais la problématique de recyclage des avions demeure. Cet article analyse la situation actuelle de la logistique inverse des avions. Il met en lumière la logistique inverse d’autres secteurs du transport ou de l’industrie informatique ou électronique pour comprendre comment structurer une logistique inverse des avions. À travers un benchmark des meilleures pratiques de recyclage dans différents secteurs industriels et des projets industriels développés par des constructeurs aéronautiques, nous illustrons les difficultés de l’intégration de la logistique inverse dans la stratégie de l’entreprise. Une démarche stratégique, plus globale et co-responsabilisante, doit être envisagée.

A sustainable supply chain in the leather sector: dilemmas, challenges and learnings

ABSTRACT This case illustrates how a French area that is inhabited by different local actors has sought to establish a new sustainable supply chain for the leather industry while accounting for the particularities of the territory and its actors. In-depth interviews were conducted with local actors. The data collected were qualitatively analysed, treated and completed through written sources. The central aim is to find key issues related to this type of supply chain and discover ways to encourage stakeholders with different goals to engage in concrete improvement at an operational level.

Analyse d’une chaîne logistique durable dans le secteur du cuir

RÉSUMÉ. Aujourd’hui, les entreprises sont confrontées à deux défis : la prise en compte de la durabilité et la criticité des ressources. Pour y répondre, les acteurs d’un territoire, le Périgord vert, et d’un secteur, le cuir, souhaitent réaliser une nouvelle chaîne logistique durable. Une présentation du secteur du cuir, des particularités du territoire et des acteurs montre le contexte. Les objectifs principaux sont les suivants : identifier les enjeux majeurs d’une chaîne logistique durable et montrer comment impliquer l’ensemble des différentes parties prenantes à travers la collaboration. Ainsi, la mise en place du projet nécessite une sensibilité des acteurs à la durabilité. Une condition nécessaire mais non suffisante pour sa pérennité est la collaboration de chaque maillon de la chaîne logistique. Chacun de ces acteurs doit trouver un avantage à s’impliquer. Ces gains durables peuvent être en termes d’image, pécunier, de sécurisation d’approvisionnement local de matières premières de qualité, de sûreté des produits ou de création d’emplois locaux.
