No. of bitstreams: 1 Analise dos Fatores Influentes nos Riscos de Descontinuidade na Cadeia de Peças de Reposição Automotivas.pdf: 1396317 bytes, checksum: 1e49dd8b0c8d353fd740b74ea0216995 (MD5) Previous issue date: 2015-12-18 / O mercado brasileiro de veículos leves possui uma frota onde 43% dos veículos têm até cinco anos de fabricação, fazendo com que os setores de reposição de peças automotivas movimentem bilhões de reais por ano. Ainda assim, é comum a falta de peças de reposição, o que exige do gerenciamento da cadeia de suprimentos a mitigação dos riscos de descontinuidade. Este trabalho analisa os riscos de suprimentos na cadeia de peças de reposição nas redes concessionárias de veículos leves por meio da priorização das variáveis que influenciam a descontinuidade de suprimentos desta cadeia. O método aplicado apresenta uma abordagem quali-quanti junto às concessionárias da região Sul Fluminense. Estas concessionárias representam quatorze das principais marcas atuantes no Brasil com um volume de vendas na ordem de 93% em 2015. As variáveis mais importantes são capacitação da equipe, comunicação e lead time. A pesquisa também evidencia que fatores organizacionais são relevantes para o suprimento de peças de reposição o que não é indicado pela literatura, juntamente com os fatores relacionados à cadeia de suprimentos. / The Brazilian market for light vehicles has a fleet where 43% of vehicles have up to five years of manufacture, causing the spare sectors of automotive parts move billions a year. Still, it is common to lack of spare parts, which requires management of the supply chain to mitigate the discontinuity risks. This paper analyzes the risks of supply in the chain of spare parts for light vehicle dealerships networks by prioritizing the variables that influence the supply disruption in this chain. The applied method presents a qualitative and quantitative approach with the concessionaires of the South Fluminense region. These dealerships represent fourteen major brands operating in Brazil with a sales volume of around 93% in 2015. The most important variables are staff training, communication and lead time. The survey also shows that organizational factors are relevant to the spare parts supply which is not mentioned in the literature, together with the factors related to the supply chain.

Securing lithium supply for a cleaner energy consumption pathway: A systems thinking on supply disruptions

Yang, Yuru January 2021 (has links)
To mitigate climate change and realize the transition towards a cleaner consumption pattern, the development of EVs needs to be ensured as it is one of the major solutions to the fossil fuel-related problems human beings face today. Lithium, as a critical material to EV cells, is seen as a strategic resource in many countries. Given the fact that the global lithium distribution is quite uneven, securing lithium supply for the development of EVs is essential for the world to phase out fossil fuels consumption in the transport sector. The supply risks of lithium can be observed in many aspects, ranging from lithium production to geopolitics. In this paper, the author combines qualitative and quantitative analysis in order to overarchingly reflect the global supply disruptions of lithium. In the qualitative section, the concept of systems theory is applied, supported by the connection circle, the stock-flow model, and the panarchy model; in the quantitative section, the author uses the combination of Herfindahl-Hirschman Index (HHI) and Worldwide Governance Indicators (WGI) to measure the extent of supply disruptions in a certain year. The quantitative section serves as a good supplement to the qualitative analysis. The qualitative results indicate that lithium mining and processing plays the key role in the whole lithium supply chain. It can be affected by the factors in the larger global context such as global political environment and the demand for lithium, as well as the social, ecological and technical components in the smaller scale that provides a physical environment for lithium production. The quantitative results show that the global supply disruptions of lithium are significant in 2019, mainly due to the high level of supply concentration. The author suggests that the governments of major lithium producer countries might organize panel discussions regularly to ensure the stable and non-centric supply of lithium to the global market. The rich production countries may also offer technical support to the less developed lithium holders to help the latter overcome the difficulties brought by the increasing cost of mining.

A Model to Assess Supply Risk for Antibiotics in Swedish Context : Analysis of Supply Structure of 39 Selected Antibiotics

Sriram, Prasad, Milind, Abhishek January 2020 (has links)
The gap between demand and supply for antibiotics in the healthcare sector has seen a steady growth over the past decades, further increasing the risk of antibiotic resistance and unavailability in the Swedish healthcare sector and market. The thesis is part of the work of the multisectoral platform, PLATINEA, which is working towards better availability of antibiotics. This study focuses on analysing the supply structure of antibiotics and pharmaceutical supply chains using a risk assessment model. A literature review of previous research has been done to identify risk factors, understand their importance and develop the risk assessment model. The risk assessment model uses these risk factors to assess the supply risk of an antibiotic. The study is designed in a quantitative manner, where the antibiotics are classified as very high, high, medium, and low risk of shortage using risk scores. Expert opinions were collected using a self-completion questionnaire, in which experts allocate weights that measure the importance of said risk factors. Weights were used to measure value of risk for antibiotics using MCDA process. The outcomes of the study are (1). the weights of risk factors given by industry experts, (2). the developed multi-criteria risk assessment model, (3). ranking of selected 39 antibiotics from high to low supply risk, based on re-assessed risk scores.

Downstream-Risiken in der automobilen Wertschöpfungskette: Instrument zur Risikobewältigung in der Kundenbeziehung von Automobilzulieferern / Downstream Risks in the Automotive Supply Chain: A Risk Mitigation Instrument for Automotive Suppliers in their Customer Relationship

Erler, Felix 03 June 2015 (has links) (PDF)
Die Automobilzulieferindustrie ist von einem Risikotransfer betroffen. Neben der Anzahl der Risiken steigt auch die Schadenshöhe. Weiterhin sind die Auswirkungen sowie die Eintrittswahrscheinlichkeiten zunehmend schwerer zu beurteilen. Unter diesem Aspekt gewinnt das Risikomanagement in automobilen Wertschöpfungsketten eine enorme Bedeutung. Die Dissertation klärt, welche Downstream-Risiken für Automobilzulieferer in der Wertschöpfungskette bestehen, welche Bedeutung diese haben, und führt Maßnahmen der Risikobewältigung zusammen. Dies erfolgt für sechs Risikokomplexe: Stückzahl und Forecastqualität, Wertschöpfungstiefe, Produktentwicklung, Prozessentwicklung, Kundeneinkäufer und Plattform- und Modulbauweise in den Schnittstellen zwischen OEM und 1st-tier Lieferanten sowie zwischen 1st-tier Lieferanten und 2nd-tier Lieferanten. Einerseits liefert die Arbeit einen Beitrag zur Risikoforschung zu Supply Chain Risks und andererseits richten sich die Ergebnisse an die Automobilzulieferer, indem ein aggregiertes Instrument zur Risikobewältigung vorgestellt wird. Dazu wurden bei 95 Automobilzulieferern Intensivinterviews durchgeführt. Die zusammenfassenden Erkenntnisse mündeten in ein spezifisches Risikomanagementmodell. Im Ergebnis wurden 29 Downstream-Risiken identifiziert, bewertet und 40 Risikobewältigungsmaßnahmen mit 125 Untermaßnahmen erarbeitet.
