The use of multi-criteria approaches in decisions concerning the selection of sustainable suppliers can be a valuable approach for helping to resolve the complexity of this process. A systematic review of the literature highlighted gaps in the research in this area, such as the lack of a detailed description of multi-criteria methods, as well as a scarcity of sustainability criteria that take into account the three main perspectives (Economic, Environmental, and Social). This work describes the development and real case application of a DEMATEL (Decision-Making Trial and Evaluation Laboratory) and ANP (Analytic Network Process) fuzzy modeling technique for the selection of sustainable suppliers. The methodological approach used in the research was quantitative, descriptive, and empirical. The modeling and simulations were performed using MATLAB®. Incorporation of the specificities of the process of selection of sustainable suppliers makes the model a useful tool for use by both businesses and researchers concerned with the issue of sustainability. A systematic review of the published research highlights the main state-of-art methods and criteria used for the selection of green and sustainable suppliers. The model is described in a framework highlighting each step of the application. It was subsequently applied by a major glass packaging company, where the supply chain coordinator agreed to assist in the research. The outputs of the second phase of the model showed that the Economic cluster was most important and interacted with the Environmental cluster, while the Social cluster remained practically inert, without interactions with the other clusters. For the three perspectives, the three most influential criteria were as follows: cost, compliance, and quality (Economic perspective); environmental certifications/ISO 14001, reuse/recovery, and pollution control (Environmental perspective); and stakeholder rights, respect for policies, and encouragement of the development of self-sustainable recycling programs (Social perspective). Finally, a supplier was selected using the framework presented, and the criteria that most influenced the decision were highlighted. The procedure developed here offers a tool to assist businesses searching for sustainable solutions, as well as researchers in the scientific community concerned with the development of knowledge in this area. / A temática sustentável, cada vez mais presente e atuante no cotidiano das operações das empresas precisa ser tratada no contexto da seleção de fornecedores. Aplicar abordagens de decisão multicritério para a seleção de fornecedores sustentáveis demonstra ser uma alternativa interessante a fim de lidar com a natureza complexa deste processo. Por meio de uma revisão sistemática da literatura foi possível destacar algumas lacunas de pesquisa, como a falta de uma visão detalhada dos métodos multicritérios e uma escassa abordagem de critérios sustentáveis, abordando as três perspectivas (Econômica, Ambiental e Social). Desta forma, o objetivo central da pesquisa é detalhar e aplicar em um caso real a modelagem fuzzy DEMATEL (Decision-making Trial and Evaluation Laboratory) e fuzzy ANP (Analytic Network Process) para a seleção de fornecedores sustentáveis. A abordagem metodológica empregada na pesquisa é quantitativa descritiva empírica, com aplicação de modelagem e simulação em MATLAB ®. Espera-se que o modelo possa internalizar as especificidades do processo de seleção de fornecedores sustentáveis de modo a tornar-se uma ferramenta útil às empresas e aos pesquisadores que estudam o método. A revisão sistemática da pesquisa pode destacar os principais métodos na literatura e os principais critérios utilizados pela seleção de fornecedores verdes e sustentáveis no estado da arte. O modelo foi detalhado em um framework, destacando-se cada passo da aplicação. Posteriormente foi aplicado em uma empresa de grande porte de embalagens vítreas, onde a coordenadora de Supply Chain se dispôs a auxiliar na pesquisa. Como saídas da segunda fase do modelo, o cluster Econômico revelou ser o mais importante e exerce influência sob o cluster Ambiental, já o cluster Social permanece praticamente inerte sem exercer ou receber influência. Também pode-se destacar que os três critérios mais influentes de cada perspectiva foram: ‘Custo’, ‘Compliance’ e ‘Qualidade’ na perspectiva Econômica; ‘Certificações Ambientais / ISO 14001’, Reuso / Recuperação e ‘Controle da Poluição’ na perspectiva Ambiental; e ‘Direitos dos Stakeholders’, ‘Respeito pelas políticas’ e ‘Incentivo ao desenvolvimento de programas de reciclagem auto-sustentáveis’ na perspectiva Social. Ao final, um fornecedor é escolhido com o framework apresentado, e os critérios mais influentes na decisão foram destacados. Esta discussão é válida para auxiliar empresas em busca de soluções sustentáveis e pesquisadores na área que desenvolvem o conhecimento para a comunidade científica.

Background: Research provides insights on the concept of sustainability in the field of supply chain management, by comparing the theoretical concept of SSCM and the practical understanding or focus of brand owners while representing sustainability. Research describes the value and significance of all three elements of sustainability to prevent brand reputational damage. By investigating and identifying effective ways to manage and improve supplier’s sustainability, the study contributes to the supply chain management field. Research aim: The research aims to highlight the concept of sustainability in supply chain management by consideration and integration all three elements of sustainability. More precisely, the study aims to display the importance of sustainability with supply chain partners for brand owners. Also identifying the effective ways that could support brand owners to manage and improve their supplier's sustainability. Methodology: A qualitative approach was followed, with semi-structured interviews that were conducted with five managers across four companies in Scandinavia. Findings: The research identified that product-based brands can improve their sustainability standards with suppliers by monitoring, motivating, and influencing them. Although it is not a simple process and comes with challenges such as certain factors like company size, the location of the suppliers and the relationship with suppliers.

The purpose of this essay was to lay the foundations for a model in the form of a question battery that can help buyers compare the sustainability responsibilities of different suppliers, so that the buyer can choose the supplier that contributes most to the Sustainable Development Goals (SDG). The model is designed as a question battery to enable the buyer to ask more comprehensive questions to the various suppliers regarding social, ecological and economic sustainability than they do today.   In order to find questions on an overall ethical level I have investigated how the global institutions intend us to navigate and prioritize between the SDGs, I have also applied the Aristotelian and Kantian ethics and Archie Carrol's model, the CSR pyramid, to broaden the ethical perspective in the questions to the companies.   The result is a question battery with questions about the company's vision and global goals, about the company's values ​​linked to all stakeholders, questions about whether the internal good and the external good are in harmony with society, questions about the company's value chain and business model and a larger stakeholder analysis.   How should a buyer then be able to evaluate a supplier's different answers? This essay aimed to create the first questionnaire with a broad question battery, the next step is to evaluate the different answers. / Syftet med den här uppsatsen var att lägga grunden till en modell i form av ett frågebatteri som kan hjälpa inköpare att jämföra olika leverantörers hållbarhetsansvar, så att inköparen ska kunna välja den leverantör som bidrar mest till de globala målen.  Modellen är utformad som ett frågebatteri för att inköparen ska kunna ställa mer omfattande frågor till de olika leverantörerna angående social, ekologisk och ekonomisk hållbarhet än vad de gör idag.   Mitt tillvägagångssätt har varit att undersöka hur de globala institutionerna tänker sig att vi ska navigera och prioritera mellan de globala målen, genom att övergripande backa tillbaks till de hållbarhetsdokument som togs fram redan på 1980-talet och sedan arbeta mig vidare till de globala mål som kom 2015 och fram till de guider som finns för ett hållbart näringsliv idag. För att hitta frågor på en övergripande etisk nivå har jag tagit hjälp av den aristoteliska och den kantianska etiken samt Archie Carrols modell, CSR pyramiden, för att bredda det etiska perspektivet i frågeställningarna till företagen.  Resultatet blev ett frågebatteri med frågor om företagets vision och de globala målen, om företagets värderingar kopplat till samtliga intressenter, om det internt goda och det externt goda är i samklang med samhället, frågor om företagets värdekedja och affärsmodell samt en större intressentanalys. Hur ska en inköpare kunna värdera en leverantörs olika svar? Den här uppsatsen syftade till att skapa det första frågeformuläret med ett brett frågebatteri, nästa steg är att värdera de olika svaren.
