Background: In a larger picture, companies are hiring third party logistics operators who have the task to manage all or part of logistics operations such as storage, transport and packaging. The case company strives to constantly improve in order to get a better understanding of the requirements in connection with procurement. More and more demands are placed on the corporates responsibility along with the procurement. Corporate social responsibility describes a company’s responsibility judging by three dimensions: Ecologic, economic and social. Purpose: The purpose is to decide from a corporate social responsibility perspective which demands are meaningful while purchasing logistic services from a third party logistics operator. Method: This study is a case study at a third party logistics operator. The study is built upon an abductive research approach and the results are collected through semi- structured interviews with the company along with the three potential customers. This theoretical referencing is built from scientific article, books and websites. Conclusion: The amount of requirements put on a third party logistics operator from an economical responsibility perspective is twice as much with ecological responsibility perspective. The least demands is required by social responsibility. The operator’s price and quality on the service, correctly maintained goods, withholding of vehicles, ability to communicate electronically and localizing are the requirements that are made from the economical responsibilities perspective. Fuel usage and environmental class vehicles and that the operator has an environmental goal are required by ecological responsibilities perspective. The social responsibilities perspective requires long-term collaboration and fair working conditions. This study has contributed knowledge about the requirements by corporate social responsibilities three dimensions and how they affect third party logistics operator. / Bakgrund: I en allt större utsträckning anlitar företag tredjepartslogistik-aktörer som har till uppgift att sköta hela eller delar av logistikverksamheten som lagring, transportering och paketering. Fallföretaget, som är en tredjepartslogistik-aktör, strävar efter att ständigt förbättras för att få en ökad förståelse för de krav som ställs i samband med upphandling. Allt fler krav ställs på företags ansvarstagande i samband med upphandling. Corporate social responsibility beskriver ett företags ansvarstagande utifrån tre dimensioner: ekologiskt, ekonomiskt och socialt. Syfte: Syftet är att utifrån corporate social responsibility utforska vilka krav som är betydelsefulla vid inköp av logistiktjänster från en tredjepartslogistik-aktör. Metod: Denna studie är en fallstudie hos en tredjepartslogistik-aktör. Studien bygger på en abduktiv forskningsansats och resultatet är insamlat genom semistrukturerade intervjuer med fallföretaget samt tre potentiella kunderna. Den teoretiska referensramen är uppbyggd utifrån vetenskapliga artiklar, böcker och hemsidor. Slutsats: Antalet ställda krav på en tredjepartslogistik-aktör utifrån ekonomiskt ansvarstagande är dubbelt så många jämfört med ekologiskt ansvarstagande. Minst krav ställs utifrån socialt ansvarstagande. Aktörens pris och kvalitet på tjänsten, korrekt hantering av gods, underhåll av fordon, förmåga att kommunicera elektroniskt och lokalisering är krav som ställs utifrån ett ekonomiskt ansvarstagande. Bränsleval och miljöklass på fordon samt att aktören har ett miljömål är krav som ställs utifrån ett ekologiskt ansvarstagande. Långsiktigt samarbete och rättvisa arbetsvillkor är krav som ställs utifrån socialt ansvarstagande. Denna studie har bidragit med kunskap angående ställda krav utifrån corporate social responsibility:s tre dimensioner och hur de påverkar valet av tredjepartslogistik-aktör.

O enfoque de sustentabilidade em cadeias de suprimento tem recebido atenção crescente na área acadêmica e no meio empresarial, nos últimos anos. A pesquisa acadêmica sobre sustentabilidade em cadeias de suprimento iniciou-se há aproximadamente uma década e a literatura aponta carência de abordagem sobre a dimensão social da sustentabilidade, com recomendação para o desenvolvimento de frameworks específicos para identificar práticas de sustentabilidade social em cadeias de suprimento. Visando contribuir para o preenchimento desta lacuna, tem-se como objetivo desenvolver e verificar a eficácia de um framework para esta finalidade. Tendo-se como referência uma revisão de literatura, propõe-se um framework composto por critérios e indicadores, que abrange a empresa produtora de bens e/ou serviços, fornecedores, distribuidores, atacadistas, stakeholders, comunidades e clientes. Para viabilizar a aplicação prática do framework, busca-se propor indicadores que sejam ao mesmo tempo, relevantes e simples. A aplicação do framework é realizada em uma cadeia de suprimento formada por três empresas do setor sucroenergético, que foi escolhido em função da representatividade desta atividade na economia brasileira, pelo volume significativo de mão de obra empregada, por registros existentes na literatura sobre condições severas de trabalho e violações de direitos humanos no setor, além do interesse internacional por sustentabilidade social na produção de etanol no Brasil. O cálculo dos indicadores nas empresas selecionadas confirmou a eficácia do framework na identificação de práticas sociais sustentáveis em cadeia de suprimento. Além desta utilidade, o framework auxiliou no diagnóstico de aspectos carentes na abordagem de sustentabilidade social, podendo apoiar na priorização de pesquisas e no estabelecimento de metas para o desenvolvimento sustentável. / Sustainability in supply chains has received increasing attention in academic and business communities, in recent years. Academic research on sustainable supply chain management has begun about a decade ago and the literature indicates scarcity of studies on the social dimension of sustainability, with recommendation for the development of explicit frameworks to inform the implementation of social sustainability in supply chains. To assist filling this gap, based on a literature review it is proposed a framework to identify social sustainability in a focal company supply chain, encompassing internal operations, its suppliers, stakeholders, wholesalers, distributors and customers. It was attempted to propose indicators that are both relevant and simple, in order to enable framework practical application. The framework is applied in a sugar cane industry supply chain, which has been chosen due to its representativeness in the Brazilian economy, the significant employed workforce, literature records on severe labor conditions and human rights violations in the sector, as well as due to international interest in social sustainability in bioethanol production in Brazil. The indicators calculation confirmed the effectiveness of the framework to identify sustainable social practices in a supply chain. Besides this utility, the framework helped to diagnose social sustainability scarce aspects in a supply chain and it may assist to prioritize research, as well as to set goals for sustainable development.

Inom byggindustrin är det svårt att skapa standardiserade logistikprocesser eftersom det vid varje nytt bygge även skapas en ny organisation. Förutsättningarna skiljer sig även mellan olika byggen, vilket försvårar ett förbättringsarbete. Skanska Väg och Anläggning Norr fick under 2017 uppdraget att bygga om Vasaplan i centrala Umeå, och i september 2018 stod projektet klart. Ombyggnationen var i det stora hela ett mycket lyckat projekt, men efter färdigställandet av projektet har problem angående materialtillgång identifierats. Syftet med arbetet är att undersöka hur leveranser till en byggarbetsplats kan optimeras samt hurvida ett mellanlager kan underlätta hanteringen av leveranserna till byggarbetsplatsen. En jämförelse har gjorts där det har undersökts ifall det är mer lönsamt att använda sig av lagerhållning, eller endast av JIT-leveranser. Förhoppningen är att arbetet kan bidra till att Skanska i framtiden får ett mer standardiserat tillvägagångssätt vid planering av leveranser till byggarbetsplats av material som kräver liknande lagerhållning och transport som granithällar. För att lösa detta har två matematiska modeller använts; Anläggningslokaliseringsproblemet (ALP) samt en matematisk modell som optimerar placering av material på en lageryta. Två stycken produktionsflödesmodeller, JIT och EOQ, har även använts i beräkningarna. Resultatet från produktionsflödesmodellerna, JIT och EOQ, visar att JIT-leveranser med hjälp av en omlastningscentral alltid är den mest kostnadseffektiva lösningen då lageryta är en direkt kostnad för Skanska. I de fall lager inte är en direkt utgift för Skanska så rekommenderar den matematiska modellen för ALP en optimal användning av de lager som är tillgängliga. / For every new construction project, a new organisation is created. It is therefore a challenge for the construction industry to create standardized logistic processes. In addition, different construction projects have different traits, which results in further challenges for improvement efforts for the construction logistic processes. In 2017 Skanska Väg och Anläggning Norr did the reconstruction of Vasaplan in the central of Umeå, and in September 2018 the reconstruction project was done. The reconstruction was in its entirety a very successful project, however when the project was finished problems regarding material supply were identified. The aim of this paper is to analyze how deliveries to a construction site can be optimized and whether storage spaces can aid in the handling of deliveries to the construction site. A comparison has been made between storing material and using JIT-deliveries. The hope is to help Skanska in developing a more standardized approach when it comes to planning the deliveries of materials that has similar storage and transport conditions as the slabs of granite used. To solve this two mathematical models have been used; Facility location problem and a mathematical model that optimizes the placement of materials in a storage space. Two production flow models, JIT and EOQ, were also used when performing the calculations. The result from the production flow models, JIT and EOQ, show that JIT deliveries are always the most cost effective solution when storage space is a direct cost for Skanska, when used together with a logistics center. However, when storing is no extra expense for Skanska, the mathematical model for the Facility location problem suggests a optimal use of the storage spaces that are available.

Until recently, the concept of green logistics has been disregarded by various logistics and transport companies in South Africa. The study on which this dissertation is based explored the green logistics practices that these companies are currently implementing in terms of the key drivers, benefits and barriers. A quantitative research approach was followed, were a survey (Lime) served as the primary research instrument. A census was conducted among 160 companies in Gauteng. The results of the study revealed a significant difference between SMEs (<200) and large (200 and above) companies with regard to their importance rating on green logistics practices. To achieve the primary objective of the study, a framework in green logistics was drafted for SMEs and large companies in South Africa, which outlined practices and opportunities companies can implement in their own businesses to benefit from ‘going green’.

O presente estudo endereça esse pilar social e a lacuna relacionada aos mecanismos de governança no âmbito da SSCM e aborda a seguinte questão de pesquisa: como empresas focais adotam a sustentabilidade social e quais mecanismos de governança são usados para implementá-la na cadeia de suprimentos? O trabalho propõe uma investigação empírica por meio de um estudo de casos múltiplos, composto por seis casos. A pesquisa identificou nos casos os antecedentes de sustentabilidade, isto é, os elementos que os direcionam, facilitam e dificultam na adoção da sustentabilidade ao longo da cadeia de suprimentos. Uma lista de mecanismos foi elaborada e classificada quanto ao seu tipo e quanto a sua atuação, se mais direta (hands-on) ou mais indireta (hands-off). Ademais, as questões sociais foram classificadas quanto a sua incidência nos casos e, para cada mecanismo de governança, três tipos foram estabelecidos: questões sociais centrais, questões sociais periféricas e questões sociais remotas. Considerando a relação entre os tipos de questões sociais implementadas e a intensidade de mecanismos de governança que as endereça, três perfis de gestão da sustentabilidade social no contexto da SSCM são delineados e descritos: elementar, seletivo e extensivo. Cada perfil foi analisado à luz de diferentes teorias: a Teoria dos Stakeholders, a Teoria de Contingência e a Teoria Comportamental. Um ponto de destaque na primeira lente teórica relaciona-se a saliência do fornecedor nos diferentes perfis: no perfil seletivo, um grupo forte de fornecedores atua como stakeholders perigosos, enquanto nos perfis seletivos e extensivos, fornecedores atuam, de modo geral, como reivindicadores. Os diferentes papéis dos fornecedores indicam que a maior ou menor incidência de poder do fornecedor influencia a extensão que a empresa focal consegue endereçar questões sociais em sua cadeia, se mais limitadas a questões centrais ou se alcançam questões periféricas e remotas. Sob a lente da Teoria de Contingência, o presente estudo indica que iniciativas sociais relacionam-se a fatores como (des)equilíbrio de poder e dependência na relação com fornecedor. Ademais, para gestão de questões sociais, aproximar-se de fornecedores não implica na redução de mecanismos de governança, principalmente, em cadeias de maior criticidade. Em relação a Teoria Comportamental, os resultados do estudo representam como conceitos dessa lente teórica manifestam-se no âmbito da sustentabilidade e da sustentabilidade social na SCM. Reconhecer tais contextos constitui um passo em direção a superação de comportamentos tendenciosos no processo de tomada de decisão na SSCM, como: reconhecer a gama de questões sociais possíveis de endereçar e priorizar aquelas mais alinhadas ao seu negócio e não as mais simples de endereçar, atuando de modo mais assertivo e não segundo o mais simples; estimular o reconhecimento mais ágil da necessidade de critérios mais complexos para definir o grupo de fornecedores a ser avaliado socioambientalmente em programas de gestão. / The social pillar of sustainability is under-represented in the context of SSCM. The present study addresses this social pillar and the gap related to governance mechanisms within the SSCM and addresses the following research question: how focal firms adopt social sustainability and what governance mechanisms are used to implement it throughout their supply chain? The paper proposes an empirical investigation through a multiple case study, composed of six cases. The research identified in the cases the antecedents of sustainability, that is, the elements that drive, enable and barriers the adoption of sustainability along the supply chain. A list of mechanisms has been elaborated and classified according to its type and its implementation, whether it is more direct (hands-on) or more indirect (hands-off). In addition, social issues were classified as to their incidence in cases and, for each governance mechanism, three types were established: central social issues, peripheral social issues and remote social issues. Considering the relationship between the types of social issues implemented and the intensity of governance mechanisms that address them, three profiles of social sustainability management in the context of SSCM are outlined and described: elementary, selective and extensive. Each profile was analyzed in the light of different theories: Stakeholders Theory, Contingency Theory and Behavioral Theory. A prominent point in the first theoretical lens relates to the salience of the supplier in the different profiles: in the selective profile, a strong group of suppliers acts as dangerous stakeholders, while in the selective and extensive profiles, suppliers generally act as claimants. The different roles of suppliers indicate that the supplier's greater or lesser incidence of power influences the extent to which the focal company can address social issues in its chain, whether it is more limited to central issues, or whether peripheral and remote issues are reached. Under the lens of the Contingency Theory, the present study indicates that social initiatives are related to factors such as (un)balance of power and dependence in the relationship with supplier. In addition, for management of social issues, approaching suppliers does not imply the reduction of governance mechanisms, especially in chains of greater criticality. In relation to Behavioral Theory, the results of the study represent concepts of this theoretical lens manifested in the scope of sustainability and social sustainability in SCM. Recognizing such contexts is a step towards overcoming biased behaviors in the SSCM decision-making process, such as: recognizing the range of possible social issues to address and prioritize those more aligned to the business rather than the simplest to address, acting more assertively and not according to the simplest; stimulate a more agile recognition of the need for more complex criteria to define the group of suppliers to be evaluated socio-environmentally in management programs.

Fish and shellfish are important sources of protein for the world population. Nearly 50 percent of fish and shellfish products originate from aquaculture, and the rest comes from traditional fishing. The marine stocks are under threat from unsustainable fishing practices. Together with fishing, aquaculture constitutes extra stress on the marine stocks and ecosystems. Aquaculture also causes other environmental side effects. International trade rules do not sufficiently take care of the ecological problems. Voluntary initiatives, like ecolabels, are one way of dealing with the problems. This thesis does an attempt to, from an environmental science perspective, analyze how the fish counters at four ICA Kvantum stores in the Stockholm region work with ecological sustainability issues with regards to fish and shellfish. The overall purpose is to examine the shops’ historical, current and potential future work and to analyze if the work is conducted in a proactive, reactive or in a passive way. The main findings include that the knowledge, sustainability statuses, responsiveness, and changes in time, and the intentions or plans for the future differed a lot between the different shops. Furthermore, many of the investigated potential problem areas seemed to constitute problems in practice. Additionally, it seemed like additional pressure may be needed if the aggregated ecological status should be raised. The research method consisted of case studies with semistructured qualitative interviews and analysis of corporate documents, and a minor quantitative investigation of the frozen assortment at the stores. / Fisk och skaldjur är en viktig proteinkälla för världens befolkning. Nära hälften av fisk- och skaldjursprodukterna internationellt kommer idag från akvakultur (fiskodlingar). Resten kommer från traditionellt fiske. De marina fisk- och skaldjursbestånden hotas i olika grad av ohållbart fiske. Tillsammans med fisket utgör olika former av akvakultur påfrestningar mot fisk- och skaldjursbestånd och de marina ekosystemen. Akvakultur orsakar även andra ekologiska sidoeffekter. Internationella handelsregler tar idag inte tillräcklig hänsyn till de ekologiska problemen. Frivilliga initiativ såsom miljömärkningar har uppkommit och kan eventuellt utgöra en del av lösningarna på problemen. Denna kandidatuppsats gör utifrån ett miljövetenskapligt perspektiv ett försök att analysera hur ”fiskdiskarna” i fyra ICA Kvantumbutiker i Stockholms län arbetar med ekologisk hållbarhet vad gäller fisk och skaldjur. Övergripande syftet är att undersöka livsmedelsbutikernas historiska, nuvarande och potentiella framtida arbete med de ekologiska hållbarhetsfrågorna, samt att analysera om de arbetar utifrån ett proaktivt, reaktivt eller passivt angreppssätt. Huvudresultaten visar att arbetet mellan butikerna skiljde sig mycket med avseende på kunskaper, ekologiska hållbarhetsteman, proaktivitet/ reaktivitet/ passivitet, förändringar över tiden, samt vad gäller intentioner och planer för framtiden. Vidare så verkade flera av de studerade ekologiska problemområdena på olika sätt utgöra verkliga problem. Någon form av påtryckningar verkade vara nödvändigt om butikernas arbete, aggregerat sett, skulle ställas om till en mer ekologiskt hållbar status. Metoden utgjordes av fallstudier med semistrukturerade kvalitativa intervjuer och studier av utvalda centrala dokument från ICA-koncernen relaterade till det tematiska undersökningsområdet. En mindre kvantitativ utvärdering av butikerna frysta sortiment gjordes också.

La maîtrise des risques est un enjeu majeur pour les entreprises. Loin d’être l’apanage des seules catastrophes naturelles, les perturbations des chaînes logistiques actuelles peuvent parfois être causées par des événements mineurs amplifiés par les failles d’organisations industrielles de plus en plus complexes. Nombreux sont les exemples de ces perturbations avec des conséquences économiques graves.La gestion des risques dans les chaines logistiques est un thème récent et les méthodes et outils actuels ne répondent pas encore totalement aux préoccupations des gestionnaires de ces chaînes logistiques. Une grande aide peut être apportée par la simulation des événements affectant les chaînes. Cependant malgré son efficacité pour couvrir la complexité de la chaîne, la simulation reste encore difficile à mettre en œuvre, notamment dans les phases de création et d’exploitation des modèles.Le but de cette thèse est de faciliter l’utilisation de la simulation pour l’analyse des risques dans les chaines logistiques. Ainsi, nous avons développé un référentiel de modélisation pour la simulation qui permet d’assurer une construction facile des modèles de la structure, du comportement et des risques inhérents aux chaines logistiques. Ce référentiel est bati sur un ensemble de metamodèles et de bibliothèques adaptés à la définition de chaînes logistiques et définis sur la base du référentiel SCOR. Ajouté à cela, nous avons proposé un guide de traduction permettant le passage d’un modèle conceptuel de chaîne logistique vers un modèle de simulation permettant de tester les scénarios de risque. Une bibliothèque de modules de simulation a été proposée pour accompagner ce passage. Une étude de cas a été menée pour tester et valider partiellement l’approche proposée. / Controlling risks is an important issue for companies. Far from being only the prerogative of natural disasters, the disruptions of today's supply chains can sometimes be caused by minor events amplified by the flaws of increasingly complex industrial organizations, causing severe economic losses.Risk management in supply chains is a recent theme and the proposed solutions are not yet able to meet the needs of practitioners. One of the solutions to analyse risks is using simulation. But, despite its effectiveness to cover the complexity of the chain, it still presents a major weakness which is the difficulty of implementation.The aim of this thesis is to facilitate and to adapt the simulation for risk analysis of supply chains. Thus, we have developed a modeling framework for simulation which enables an easy construction of models of supply chain structure, behavior and if the associated risks. This is done through the proposition of a set of meta-models and libraries, defined on the basis of the SCOR reference model. In addition, we proposed a translation guide for the translation of the conceptual model of supply chains into a simulation model and enabling testing risk scenario. Additionaly, we developed a library of simulation modules.A case study was conducted and the results show the relevance of the proposed approach.
