A introdução efetiva da sustentabilidade em empresas exige ações que extrapolam os limites organizacionais, abarcando o ambiente interorganizacional. Dessa maneira, as empresas deixam de ser consideradas isoladamente e passam a ser analisadas de acordo com suas cadeias de suprimentos, compostas por organizações que contribuem para o alcance dos mesmos objetivos de desempenho. Nesse sentido, uma cadeia de suprimentos é considerada mais sustentável quando insere as dimensões econômica, ambiental e social em suas operações, nas estratégias e na tomada de decisão, possuindo bons níveis de desempenho em tais dimensões. A adoção de práticas de sustentabilidade em cadeias de suprimentos pode ser analisada em um contínuo, formado por dois extremos: a resposta reativa e proativa. Nesse contexto, a proatividade de práticas sustentáveis pode ser definida como a adoção de ações, realizadas voluntariamente por empresas, com a finalidade de melhorar o desempenho ambiental e o desempenho social, além das exigências legais. A empresa proativa afirma sua preocupação e seu compromisso com a sociedade e o ambiente natural, em que está inserida. Diante dessas considerações, tem-se a premissa dessa pesquisa: a postura proativa de empresas em relação a práticas sustentáveis estimula melhor articulação com os elos de sua cadeia de suprimentos, o que colabora para a introdução da sustentabilidade nessa cadeia. O objetivo desta pesquisa é analisar a contribuição da articulação de uma empresa proativa com seus elos para a introdução da sustentabilidade na sua cadeia de suprimentos. Para tanto, foi realizada uma pesquisa qualitativa, distribuída em duas etapas (exploratória e descritiva), envolvendo uma empresa focal proativa e parceiros de sua cadeia de suprimentos. Ressalta-se que, em virtude da complexidade e da extensão de cadeias de suprimentos, optou-se por analisar a cadeia à montante, isto é, foram entrevistados colaboradores da empresa focal (Mercur S.A.) e de empresas fornecedoras (LKC Transportes; PAMF Indústria e Comércio de Confecções; Caeté Embalagens; e, Artecola Química). Primeiramente, foi analisada a proatividade de práticas sustentáveis da Mercur. Os resultados indicam que a Mercur pode ser considerada uma empresa proativa, em função da implantação total de 37 ações em prol da sustentabilidade ao core business da organização e da implantação parcial de seis práticas. Em segundo lugar, investigou-se a articulação e o relacionamento da empresa proativa com os elos de sua cadeia de suprimentos. Verificou-se que os entrevistados consideram que os elos estão em processo de integração. Diante disso, pode-se observar que existem diferentes níveis de articulação na cadeia de suprimentos, envolvendo a Mercur e seus fornecedores. Em seguida, averiguou-se a existência de práticas sustentáveis ao longo da cadeia de suprimentos estudada, as quais foram descritas a partir de cinco categorias de análise (orientação estratégica, continuidade da cadeia de suprimentos, colaboração, gestão de risco, proatividade). Incentivos foram identificados para que práticas pró-sustentabilidade passem a ser concebidas e implantadas por todos os membros da cadeia, colaborando para um desenvolvimento mais sustentável. Nessa perspectiva, diante dos resultados encontrados, assume-se que a premissa de pesquisa foi confirmada, uma vez que a postura proativa de práticas sustentáveis da Mercur estimula maior articulação com os parceiros de sua cadeia de suprimentos, contribuindo para a inserção da sustentabilidade nessa cadeia. Entretanto, a articulação da Mercur com os parceiros também pode incentivar que posturas proativas em benefício da sustentabilidade sejam incorporadas pelas empresas da cadeia de suprimentos. / The effective introduction of sustainability in business requires actions that go beyond organizational boundaries, encompassing the inter-organizational environment. Thus, companies are no longer considered individually; they are analyzed according to their supply chains, composed by organizations that contribute to the achievement of the same performance goals. A supply chain is considered more sustainable when it enters the economic, environmental and social dimensions in their operations, strategies and decision making, possessing good levels of performance on these dimensions. The incorporation of sustainability practices in supply chain can be analyzed in a continuous, formed by two extremes: reactive and proactive response. The sustainable proactivity can be defined as the adoption of actions, performed voluntarily by companies, in order to improve the environmental and social performance beyond legal requirements. A proactive company states its concern and commitment to society and the natural environment in which it operates. Given these considerations, this research premise is: the proactive approach of companies towards sustainable practices encourages better integration with the partners in their supply chain, which contributes to the incorporation of sustainability in the supply chain. In this context, this research aims to analyze the contribution of proactive company integration with its partners to the introduction of sustainability in their supply chain. Therefore, a qualitative research was performed, composed by two phases (exploratory and descriptive), involving a proactive focal company and its supply chain partners. It is emphasized that, because of the complexity and the extent of supply chains, we chose to analyze the upstream chain, i.e., focal company (Mercur S.A.) and supplier firms (LKC Transportes; PAMF Indústria e Comércio de Confecções; Caeté Embalagens; and Artecola Química). The employees of these companies were interviewed. First, it was analyzed the proactivity of sustainable practices of Mercur. The results indicate that Mercur can be considered a proactive company, due to the full adoption of 37 actions for sustainability in the core business of the organization and the partial implementation of six practices. Secondly, it was investigated the integration and the relationship of a proactive company with its supply chain partners. It was found that the interviewees consider that the supply chain is in process of a complete integration. Thus, it can be observed that there are different levels of integration in the supply chain, involving the Mercur and their suppliers. Thirdly, it was examined the existence of sustainable practices throughout the supply chain. These practices were described considering five categories of analysis (strategic orientation, supply chain continuity, collaboration, risk management, and proactivity). Incentives were identified for the design and the implementation of sustainable practices by all supply chain members, contributing to a more sustainable development. From this perspective, given the results, it is assumed that the research premise was confirmed, since the proactive sustainable practices Mercur encourages greater integration with partners in the supply chain, contributing to the sustainable supply chain. However, the integration of Mercur with partners can also encourage that proactive practices in favor of sustainability be incorporated in the supply chain.

Introduktion: I takt med en ökad global handel och en stor konkurrens inom industrisektorn letar många företag alternativ för att stärka sin position och konkurrensförmåga. Inom Supply Chain Management sker utveckling för att bättre passa den marknad som råder. En anpassning till en föränderlig verksamhet är numera något som måste ses som en viktig aspekt i skapandet av framtida Supply Chain och en strukturerad flexibilitet är ett måste för att möta kundernas behov. Kärnkraften står efter olyckan i Fukushima inför en stor förändring då nya material måste utvecklas för att höja säkerheten i världens kärnkraftreaktorer. I och med detta måste också nya produktionsvägar skapas och försörjningskedjan måste utvärderas för att möta kundens önskemål. En analys av den tilltänka försörjningskedjan där de gap som finns mellan försörjningskedjans möjliga kapacitet och kundens önskade kapacitet genomförs för att säkerställa att organisationen fattar rätt beslut vad gäller expansion av kapacitet. Syfte: Syftet med studien är att undersöka avgörande parametrar som en förnyad Supply Chain kan byggas från. Därefter undersöks den specifika försörjningskedjans möjlighet att möta kundens behov. Detta genom att analysera försörjningskedjans kapacitet och de eventuella gap som finns mellan den möjliga kapaciteten och kundens önskade kapacitet. Syftet är att på detta sätt skapa goda förutsättningar för en stark och konkurrenskraftig Supply Chain. Metod: För att svara mot syftet skapades en teoretisk modell över viktiga aspekter i en Supply Chain fram. I denna undersökning har en kombination av kvalitativa och kvantitativa forskningsstrategier använts. Slutligen analyserades en specifik försörjningskedja genom en GAP-analys. Resultat: I undersökningen har ett flertal kapacitetsbegränsningar och flaskhalsar upptäckts i produktionen. Olika scenarion visar på vilka när och var dessa begränsningar uppstår. Genom GAP-analysen påvisas olika alternativ att skapa flexibilitet i försörjningskedjan. Slutsats: I slutsatsen lyfts en modell för arbetet med en Supply Chain fram. Denna sätter kundens behov i fokus och bidrar sedan till att skapa en flexibel och öppen/synlig Supply Chain. Den specifika försörjningskedjan har viss kapacitet att möta marknadens behov. Genom investeringar och flexibla lösningar så som en förändrad skiftgång och inköp av mer produktionsutrustning kan ytterligare kapacitetsbehov mötas.

The purpose of this research is to analyze different ways in which crop-chain solutions are adopted in the region of Junín, Peru. The disintegration of the SC is revealed, as each cooperative member works uncoordinatedly on his own leading to different results standards with high costs and low returns. The study focused on different entities from farmers to the port of Callao of an organic coffee supply chain where disintegration is constant. The paper describes a misaligned supply chain including poorly collaboration. All problems found will be an opportunity to develop a distribution model in the organic coffee supply chain of Junín region. / Revisión por pares

It also analyzes the current scenario of the Coffee Sector and the participation of the Supply Chain (SC) in the processing and distribution of Organic Coffee in Junin, Peru. A diagnosis was made to the certified organizations from the market. The diagnosis and the surveys indicated that they do not have a correct flow of information, shared goals and objectives, strategic decisions, and sourcing materials among the different parties demonstrating the lack of interrelationship among the members. The final objective of this research is to improve the competitiveness of these organizations through the increase in the performance of the SC, for which a model of supply chain integration is proposed. / Revisión por pares

The quinoa supply chain, an industry that has encountered a boost in market demand in the past year, is selected as the unit of analysis. Supply chain integration dynamics are analyzed to provide recommendations about integration strategies and benefits in the agricultural sector. Design/methodology/approach: A conceptual model was designed in this study, which includes the drivers (i.e. trust and commitment) and outcomes (i.e. operational and economic performance) of supply chain integration. The relationships were verified through a unique survey, the data of which were collected from 79 respondents operating at different levels of the Peruvian quinoa supply chain (i.e. suppliers, producers and customers). The proposed hypotheses were tested through the partial least squares (PLS) regression. Findings: The results underscore the relevance of trust and commitment as enablers of supply chain integration initiatives in the agri-food industry. These factors are particularly essential for involving the farmers who are the most upstream actors in the supply chain and characterized by unstructured organizations. A high level of integration in these types of supply chain enhances the capacity to improve operational performance, which in turns positively affects the main economic indicators. Originality/value: This study contributes to the discussion of supply chain integration in the agri-food industry, which remains unexplored thus far. It relies on a multitier collection of responses, which is extended to all the levels of the quinoa supply chain, thereby providing the study with a unique depth of analysis. Furthermore, this work contributes to the ongoing discourse on the performance impact of supply chain integration, which several SCM scholars have recently questioned. / Revisión por pares

The cultivation of raspberries is in the stage of potential growth opportunities for agribusiness. Output logistics is an essential part of the management of the food supply chain; this improves performance and quality in the fresh product. The cold chain and proper practice techniques preserve quality and reduce raspberry production losses by 15%. This model is based on scientific articles that are the theoretical pillars for the process methodology that develops the competitiveness of the product.

Researchers are interested in value chain analysis to identify the different opportunities for cost savings. The literature have been narrow in scope and addressed specific problems; however none has addressed the need for a general framework that can be used as a standard template in the supply chain cost management and optimization, though Dekker and Goor (2000) said that the goal was to develop a model that would allow direct comparison of specific activities between firms, such as warehousing activities costs. There was no indication in the literature of a cost model that can identify all costs and cost drivers through the supply chain. Some firms built models to analyze the effect of changes in activities but only with limited activities such as logistics. The purpose of this research is to create a general framework that can express the cost data for the partners of the supply chain in similar terms. The framework will layout the common activities identified within the firm and the relationship of these activities between the partners of the supply chain, and the framework will identify the effect of changes in activities on other partners within the supply chain. Cost information will help in making decisions about pricing, outsourcing, capital expenditures, and operational efficiency. The framework will be able to track cost through the chain, which will improve the flexibility of the supply chain to respond to rapidly changing technology. The framework will help in developing product strategy paradigms that encompass the dynamics of the market, in particular with respect to the technology adoption lifecycle.

Build-to-order supply chains (BOSCs) have recently received increasing attention due to the shifting focus of manufacturing companies from mass production to mass customization. This shift has generated a growing need for efficient methods to design BOSCs. This research proposes an approach for BOSC design that simultaneously considers multiple performance measures at three stages of a BOSC – Tier I suppliers, the focal manufacturing company and Tier I customers (product delivery couriers). We present a heuristic solution approach that constructs the best BOSC configuration through the selection of suppliers, manufacturing resources at the focal company and delivery couriers. The resulting configuration is the one that yields the best global performance relative to five deterministic performance measures simultaneously, some of which are nonlinear. We compare the heuristic results to those from an exact method, and the results show that the proposed approach yields BOSC configurations with near-optimal performance. The absolute deviation in mean performance across all experiments is consistently less than 4%, with a variance less than 0.5%. We propose a second heuristic approach for the stochastic BOSC environment. Compared to the deterministic BOSC performance, experimental results show that optimizing BOSC performance according to stochastic local performance measures can yield a significantly different supply chain configuration. Local optimization means optimizing according to one performance measure independently of the other four. Using Monte Carlo simulation, we test the impact of local performance variability on the global performance of the BOSC. Experimental results show that, as variability of the local performance increases, the mean global performance decreases, while variation in the global performance increases at steeper levels.

This dissertation examines the challenges associated with disruptions in supply chain financing and the railway transportation network. The study is divided into six chapters: In Chapter 1, we introduce the core problems under investigation. Chapter 2 investigates supply chain financing, emphasizing trade credit and bank credit—two predominant external financing mechanisms. Given the inherent uncertainties in demand, interest rates, and supplier credit ratings, this chapter introduces a stochastic programming model accounting for demand uncertainty. Subsequently, a robust optimization program is applied, whose complexity demands a specialized solution methodology. By analyzing a case study centered around a prominent U.S. retailer, the research reveals key insights into decision-making processes related to financing, the effects of bargaining power on portfolio mix and profits, and the relative importance of interest rate uncertainties over supplier credit ratings. Chapter 3 introduces a game-theoretical model designed to hedge financing risks in supply chains, with a focus on the application of insurance for both trade and bank credits. To support the design of effective supply chain finance contracts, three distinct contracts are developed, aiming to synchronize both financial and material flows within the supply chain. A significant feature of this chapter is the data-driven approach employed to address the potential bankruptcy risks that can arise from borrowing loans. Alongside this, a novel solution algorithm is introduced to solve the proposed non-convex models. A case study involving Ford Motor Company and a Chicago-based retailer enriches the research with real-world context. The findings offer several managerial insights: the strategic advantages of different insurance services vary based on the risk attitudes and profit margins of participants. For example, when a retailer operates with a lower profit margin, the use of Trade Credit Insurance (TCI) is recommended in conjunction with a risk-seeking retailer, while a risk-averse retailer might diminish the benefits of TCI. Conversely, with high profit margin retailers, the adoption of Payment Protection Insurance (PPI) is advised under all conditions. In Chapter 4, a game-theoretical model for risk mitigation within railway transportation is introduced. This model addresses random disruptions by employing strategies like repair, re-routing, third-party services, and leasing capacity from competing rail companies. Through a U.S. case study, the efficacy of these strategies is examined, with renting railcars emerging as a particularly potent approach to enhance resilience and reduce third-party expenses. The research further suggests that negotiations extending delivery dates can significantly diminish post-disruption costs. Finally, Chapter 5 summarizes the primary contributions of this research, laying the groundwork for prospective studies in this domain. / Thesis / Doctor of Philosophy (PhD)

Yes / The role of closed loop supply chains (CLSC) for creating and recovering value is widely acknowledged in supply chain management and there are many examples, mainly in the business-to-business sector, of successful OEM remanufacturing. The integration of value creation and recovery activities into retail customer value propositions is, however, under researched and raises many challenges, especially in Fast Moving Consumer Goods (FMCG) retail where few real world examples have been published. The recent emergence of the term ‘circular economy’ has initiated further debate about closed loop value propositions and closed loop supply chain implications. This paper selects four circular economy-led closed loop product case examples from a major European FMCG company, and assesses, at a high level, how these cases created value, for whom value was created, and key challenges in their implementation. The findings highlight that each case is different. Closing loops and creating successful value propositions is complex and requires simultaneous reconfiguration of key building blocks to ensure customer acceptance and business viability. The paper proposes the term ‘circular supply chain’ for cases where circular economy principles are explicitly incorporated in CLSC for value creation.
