No. of bitstreams: 1 DissFHOC.pdf: 4797220 bytes, checksum: b0135398de121773d22185e9ed8dce59 (MD5) Previous issue date: 2016-02-26 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) / Nowadays supply chains have grown in size and complexity. In this environment, unforeseen events (ruptures) in the flow of goods, services or information can occur unexpectedly, having increasingly significant impacts on companies. Resilience is defined as the ability to prepare, adapt and react to ruptures, thus maintaining operations connected and having control over the structure and functions. Considering this, the activities carried out by inbound logistics may influence creating resilience in the supply chain, mainly by including the flow of materials and supplying the company, which are activities directly affected during the ruptures. However, little is known about how the inbound logistics contribute to creating resilience. Taking this into account, the aim of this study is to identify which resilience enablers there are and how inbound logistics use them to create supply chain resilience. A systematic literature review of resilience and inbound logistics, followed by content analysis defined what the activities of inbound logistics are, which resilience enablers there are in the supply chain and also defined how the activities make use of the enablers. In the next step of the research, a multiple case study of 2 Brazilian dairies was performed. Interviews were transcribed and content analysis was conducted using the QDA Miner software. Case-by-case and cross-case analyses were carried out, observing how different types of rupture can influence the enablers used. Thus, the resilience enablers present in cases were highlighted, and the activities that use them were defined, localized facilitators were, reacting speed, collaboration, communication, supply chain structure, flexibility, risk management, product innovation, contingency planning, redundancy, company's financial health, security technology, cross-functional groups, knowledge management, visibility and supplier quality. Knowledge about the relationship between them enables the companies studied to manage their resources more profitably and extend these practices to their suppliers. It should also be mentioned that the companies studied operate with low inventory levels, therefore other companies in the same situation can use the knowledge gained from this research to administer facilitators in order to recover from ruptures. / Nos dias atuais, as cadeias de suprimento têm crescido em tamanho e complexidade. Nesse ambiente, eventos inesperados (rupturas) no fluxo de bens, nos serviços ou nas informações podem ocorrer de forma repentina, tendo impactos cada vez mais significativos às empresas. A resiliência é definida como a capacidade de preparação, adaptação e reação a rupturas, mantendo assim as operações conectadas e o controle sobre a estrutura e as funções. Nesse sentido, as atividades realizadas pela logística inbound podem influenciar a geração de resiliência na cadeia de suprimentos, principalmente por englobarem o fluxo de materiais e o abastecimento da empresa, atividades diretamente afetadas durante as rupturas. Entretanto, pouco se sabe a respeito de como a logística inbound contribui com a geração de resiliência. Nesse sentido, o objetivo deste trabalho é identificar quais são os facilitadores à resiliência e como a Logística inbound utiliza-os para a criação de resiliência na cadeia de suprimentos. Uma revisão sistemática da literatura a respeito de resiliência e de logística inbound, seguida de uma análise de conteúdo, definiu as atividades da logística inbound, os facilitadores à resiliência na cadeia de suprimentos e as atividades que fazem uso dos facilitadores. Em uma etapa seguinte do trabalho, realizou-se, um estudo multicaso considerando dois laticínios brasileiros. Para isso, foram realizadas entrevistas que posteriormente foram transcritas e submetidas a uma análise de conteúdo com auxílio do software QDA miner e foram feitas análises caso a caso e intercasos, observando como os diferentes tipos de rupturas podem influenciar os facilitadores utilizados. Desse modo, os facilitadores à resiliência presentes nos casos foram destacados, bem como definiram-se as atividades que os utilizam, os facilitadores localizados foram agilidade de reação às rupturas, colaboração, comunicação, estrutura da cadeia de suprimentos, flexibilidade, gestão de riscos, inovação do produto, plano de contingência, redundância, saúde financeira da empresa, tecnologia de segurança, grupos interfuncionais, gestão do conhecimento, visibilidade e qualidade do fornecedor. O conhecimento de como as atividades da logística inbound utilizam os facilitadores, possibilita que as empresas estudadas gerenciem seus recursos de forma mais profícua e estendam essas práticas a seus fornecedores. Destaca-se ainda que as empresas estudadas operam com níveis de estoque baixos, portanto outras empresas com a mesma condição podem utilizar-se dos conhecimentos aqui desenvolvidos para administrar os facilitadores, de forma a se recuperar das rupturas.

Creating Supply Chain Resilience with Information Communication Technology

Glassburner, Aaron 05 1900 (has links)
Supply chain resilience refers to the capability of a supply chain to both withstand and adapt to unexpected disturbances. In today's turbulent business environment, firms are continually seeking to create more resilience within their supply chain through increased information communication technology use and enhanced business-to-business relationships. The focus of this dissertation is the investigation of how information communication technology creates resilience at the differing process levels of supply chain operations. Past research into information communication technology use within supply chains has often been conducted at the macro-level of supply chain phenomena. As such, there is still much to understand about how decision-makers interact with information communication technology at the micro-level of supply chain decision-making. A more in-depth, broad coverage of this interaction will provide both practitioners and academics a better understanding of how to leverage information communication technology in achieving supply chain resilience. To meet this aim, this dissertation contains three essays that re-orient conceptual thinking about supply chain phenomenon, explore how advances in information communication technology influence business-to-business relationships, and identify how information communication technology effects the decision-making of supply chain managers.

Supply Chain Resilience: Industrial Manufactures’ Use of Disruptive Technologies

Manfredsson, Adam, Brauer, Andreas January 2023 (has links)
With a purpose to provide insights on how to reduce the impact of future disruptive events on the supply chain and to raise awareness of the potential applications of disruptive technologies (DTs), this thesis will analyze the use of 3-Dimensional Printing (3DP), Big Data (BD), and Internet of Things (IoT) in Supply Chain Management (SCM). The devastating impact of the COVID-19 pandemic has highlighted the need for greater Supply Chain Resilience (SCR), as disruptions can have a domino effect and damage co-dependent supply chain actors. Just-In-Time (JIT) and standardized supply chain practices have been blamed for operational failings, leading to calls for better strategies and solutions to prepare against future disruptions. The thesis bridges the gap in knowledge between supply chain strengthening and the potential of disruptive technologies, and what solutions are viable for supply chain managers to create more resilient SCM. The study contributes to industrial manufacturing firms managing consequences of COVID-19, and how they are implementing precautionary measures to keep their supply chain resilient for future threats. This research aims to contribute to both scholars, practitioners, and the supply chain management field.

Beyond Disruptions: Optimizing Supply Chain Resilience : A qualitative and quantitative analysis of the aftermarket supply chain

Andersson, Sara, Karlsson, Jesper January 2023 (has links)
The world is changing, what has been known to work has been put to the test when both the geopolitical and the environmental climate are changing. War, a pandemic, material shortage, financial difficulties and an overall dis- tressed global transportation sector have shown that the ever-more important topic of resilience is crucial to stay relevant in today’s competitive markets. Companies are therefore switching focus towards ensuring sufficient supply chain resilience capabilities to handle these ever-changing situations on the global market.  In this thesis, we focus on how Volvo SML is working with resilience today, and how graph theory and optimisation can be useful tools when analysing a supply chain’s resilience. We made a qualitative analysis by conducting inter- views with employees and comparing our findings with capabilities related to resilience. In addition, we conducted a quantitative analysis by constructing a simulation of the supply chain, comparing two topology metrics and two op- timisation metrics, to analyse the robustness of the aftermarket supply chain.  We analysed the data and summarised the insights gathered from the inter- views using a resilience capability framework. Volvo SML proved to be agile and reactive when dealing with disruptions but is missing some key capabil- ities during the pre-and post-disruption phases. Some areas of improvement we identified were: robustness, collaboration and redundancy. We proved that the simulation is useful when evaluating the robustness of a supply chain, and we showed that a more flexible way of working would improve the overall robustness of Volvo SML’s aftermarket supply chain.

Analytics for supply chain resilience : Exploring paths and obstacles

Seif, Martin January 2023 (has links)
Supply chain disruptions, ranging from epidemics to geopolitical tensions, have been especially evident in recent years and have consequently become a hot topic in both boardrooms and academic literature. Supply chain resilience (SCR) denotes the ability to prepare, respond, recover, and facilitate growth during disruptions and is usually thought of as consisting of several enablers. Initial evidence suggests that one such enabler could be analytics, which broadly refers to the processing of data to support decision-making. This thesis aims to explore the use of analytics for SCR. The research design comprise one conceptual component followed by two empirical components consisting of a survey and interviews. The findings reveal six application areas for analytics in SCR. Three paths to SCR are also identified in terms of configurations of analytics and other SCR enablers, only one of which does not seem to be contingent on the level of supply chain complexity. Finally, obstacles to the use of analytics were identified. Clear consensus was noted for low data availability and/or quality as a major obstacle to SCR, while a somewhat consensus existed concerning the hindrance to quick decision-making, lack of a data-driven culture, and insufficient benefits and/or use. The thesis contributes to the nascent stream of research on the use of analytics and SCR by complementing individual observations with broader and deeper insights through the spectrum of application areas, configurations of analytics and complementary SCR-enablers, and finally, obstacles. For practitioners, the thesis provides insights into using analytics as a potential enabler for SCR. Firms can evaluate their current use of analytics for SCR and adjust their set of application areas and configurations of SCR-enablers as per the options outlined in the findings to better align with their specific needs and prerequisites. Finally, guidance is provided on what obstacles to be cognizant of and attempt to mitigate. / Störningar i försörjningskedjor, orsakade av händelser såsom pandemier och geopolitiska spänningar, har varit särskilt påtagliga under de senaste åren och har därmed blivit ett hett ämne både i näringslivet och akademin. Begreppet Supply chain resilience (SCR) avser försörjningskedjans förmåga att förbereda sig, reagera, återhämta sig och stödja tillväxt under sådana störningar. Det anses vanligtvis bestå av flera möjliggörare. Initiala bevis i litteraturen tyder också på att en av dessa möjliggörare kan vara analytics, som i stora drag betyder bearbetning av data för att stödja beslutsfattande. Denna avhandling syftar till att utforska användningen av analytics för SCR. Forskningsmetoden bestod av en konceptuell studie, följt av två empiriska studier i form av en enkät och intervjuer. Resultaten visar sex tillämpningsområden för analytics med avseende på SCR. Dessutom identifierades tre vägar till SCR när det gäller konfigurationer av analytics och andra SCR-möjliggörare, varav endast en konfiguration är oberoende av försörjningskedjans komplexitetsnivå. Slutligen identifierades hinder för användning av analytics för SCR. Det fanns en tydlig konsensus kring låg tillgänglighet och/eller kvalitet på data, medan det fanns viss enighet om hinder för snabba beslut, bristen på en kultur att basera beslutsfattande på analytics och slutligen otillräcklig nytta och/eller användning. Avhandlingen bidrar till forskning om användningen av analytics för SCR genom att komplettera enskilda observationer med bredare och djupare insikter om spektrumet av tillämpningsområden, konfigurationer av analytics och kompletterande SCR-möjliggörare, och slutligen, hinder. För praktiker ger avhandlingen insikter i att använda analytics som en potentiell möjliggörare för SCR. Företag kan utvärdera sin nuvarande användning av analytics för SCR och förändra tillämpningsområden och konfigurationer av SCR-möjligare enligt de identifierade alternativen för att bättre tillgodose sina behov och förutsättningar. Slutligen ges vägledning om vilka hinder man bör vara medveten om och försöka mildra.

Assessment Of Disruption Risk In Supply Chain The Case Of Nigeria’s Oil Industry

Aroge, Olatunde O. January 2018 (has links)
evaluate disruption risks in the supply chain of petroleum production. This methodology is developed to formalise and facilitate the systematic integration and implementation of various models; such as analytical hierarchy process (AHP) and partial least squares structural equation model (PLS-SEM) and various statistical tests. The methodology is validated with the case of Nigeria’s oil industry. The study revealed the need to provide a responsive approach to managing the influence of geopolitical risk factors affecting supply chain in the petroleum production industry. However, the exploration and production risk, and geopolitical risk were identified as concomitant risk factors that impact performance in Nigeria’s oil industry. The research findings show that behavioural-based mechanisms successfully predict the ability of the petroleum industry to manage supply chain risks. The significant implication for this study is that the current theoretical debate on the supply chain risk management creates the understanding of agency theory as a governing mechanism for supply chain risk in the Nigerian oil industry. The systematic approach results provide an insight and objective information for decisions-making in resolving disruption risk to the petroleum supply chain in Nigeria. Furthermore, this study highlights to stakeholders on how to develop supply chain risk management strategies for mitigating and building resilience in the supply chain in the Nigerian oil industry. The developed systematic method is associated with supply chain risk management and performance measure. The approach facilitates an effective way for the stakeholders to plan according to their risk mitigation strategies. This will consistently help the stakeholders to evaluate supply chain risk and respond to disruptions in supply chain. This capability will allow for efficient management of supply chain and provide the organization with quicker response to customer needs, continuity of supply, lower costs of operations and improve return on investment in the Nigeria oil industry. Therefore, the methodology applied provide a new way for implementing good practice for managing disruption risk in supply chain. Further, the systematic approach provides a simplistic modelling process for disruption risk evaluation for researchers and oil industry professionals. This approach would develop a holistic procedure for monitoring and controlling disruption risk in supply chains practices in Nigeria.

Stochastic Goal Programming of Supply Chain under Disruption / Stokastisk målprogrammering av försörjningskedjan under störning

Desai, Chinmayi January 2022 (has links)
The spread of COVID-19 pandemic in the world and the importance of controlling it in all regions have made managing this crisis a great challenge for all countries. The devastating effect on global automotive supply chains due to the disruptions has resulted in losses and shut down of production facilities owing to government restrictions due to the spread of infections leading to supply breakdown across all tiers of supply chain. It has resulted in shortage of crucial components to the automobile industry. A stochastic goal programming model is developed to incorporate disruptions in the supply chain. The model is used to simulate the current crisis of COVID-19 as numerical cases. Supply chain resilient strategy such as China Plus One strategy that involves diversification of supplier base to other locations along with China is analysed. The key finding is that a China-Plus-One strategy appears to be beneficial to both parties involved, organizations that seek to pursue it for reasons of risk diversification, cost reduction or avoidance of overreliance on China and for Plus-One host economies which gain the benefits of FDI. The contribution of the study is in integrating the supply chain resilience literature and operational research tools to model a global supply chain under uncertainty and making a case for change in supply chain strategy from efficient supply chain to resilient supply chains. The study attempts to support the implementation of the China Plus One Strategy as the most suitable resilient strategy post COVID-19. / Spridningen av covid-19-pandemin i världen och vikten av att kontrollera den i alla regioner har gjort att hantera denna kris till en stor utmaning för alla länder. Den förödande effekten på globala fordonsförsörjningskedjor på grund av störningarna har resulterat i förluster och nedläggningar av produktionsanläggningar på grund av statliga restriktioner på grund av spridningen av infektioner som leder till leveransuppdelning över alla nivåer av försörjningskedjan. Det har resulterat i brist på avgörande komponenter till bilindustrin. En stokastisk målprogrammeringsmodell utvecklas för att införliva störningar i försörjningskedjan. Modellen används för att simulera den nuvarande krisen med COVID-19 som numeriska fall. En strategi för motståndskraftig leveranskedja som China Plus En strategi som innebär diversifiering av leverantörsbasen till andra platser tillsammans med Kina analyseras. Nyckelresultatet är att en China-Plus-One-strategi verkar vara till nytta för båda inblandade parter, organisationer som försöker eftersträva den på grund av riskdiversifiering, kostnadsreduktion eller undvikande av övertilltro till Kina och för Plus-One-värdekonomier som vinner fördelarna med utländska direktinvesteringar. Studiens bidrag är att integrera litteraturen om försörjningskedjans motståndskraft och operativa forskningsverktyg för att modellera en global försörjningskedja under osäkerhet och göra ett argument för förändring av strategin för försörjningskedjan från effektiv försörjningskedja till spänstiga försörjningskedjor. Studien försöker stödja implementeringen av China Plus One-strategin som den mest lämpliga motståndskraftiga strategin efter COVID-19.

Pandemin och den militära konfliktens påverkan på en monteringsverksamhet : Materialförsörjning, produktion och leveransförmåga till kund

Suljic, Admir, Åhrlin, Eric January 2022 (has links)
The pandemic (Covid-19) has since the beginning of 2020 caused major changes for many different companies. To minimize the spread of the virus several different measures have been implemented by local authorities. Additionally, a military conflict occurred between Russia and Ukraine in the early 2022, it has caused sanctions and led to many consequences including deterioration in the supply of raw materials. This study investigates a case company that assembles trucks for sewer cleaning in purpose to identify how the consequences of the pandemic and military conflict have affected its material supply, production, and delivery capacity to customers. The purpose is also to examine how the consequences can be managed to maintain an efficient business.  The study is based on an abductive research approach and the data collection was mainly based on semi- and unstructured interviews. The collected data from the interviews has then been analyzed with relevant theories.  During the pandemic the case company was affected by delivery delays, which further caused disruptions in production and a poor delivery capacity to customers. Similar outcomes are caused by the military conflict, the delivery from suppliers have deteriorated and continued to affect the production capacity of the case company, which is expected to decrease the delivery precision to customers. These consequences have caused the need of other methods than Just-in-time (JIT) to be applied during crisis, and a different view of tied up capital is also required. Measures to reduce the impacts of the pandemic have involved larger safety stocks, standardization, and innovation by building on support frames.   The study concludes that a resilient supply chain and innovative thinking can reduce the consequences of a pandemic and a military conflict, these are some of the theoretical contributions presented by the study. Further studies are proposed for similar industries to enhance generalizability. / Sedan början av år 2020 har pandemin (Covid-19) orsakat stora förändringar för många olika företag. Lokala myndigheter har infört åtgärder i syfte att förhindra smittspridningen av viruset. Vidare utlöstes även en militär konflikt i början av år 2022 mellan Ryssland och Ukraina som orsakat sanktioner, vilket lett till försämrad tillgång av bland annat råvarumaterial. Denna studie undersöker ett fallföretag som monterar slamsugningsbilar i syfte att identifiera hur deras materialförsörjning, produktion och leveransförmåga till kund påverkats av både pandemin och den militära konflikten. Den innehåller även hur konsekvenserna kan hanteras för att upprätthålla en effektiv verksamhet.   Studien utgår ifrån en abduktiv forskningsansats och där datainsamling huvudsakligen skett med semi- och ostrukturerade intervjuer. Svaren från intervjufrågorna har använts till nulägesbeskrivningen som sedan analyserats utifrån relevanta teorier.   Under pandemin påverkades fallföretaget av längre leveransförseningar, som vidare orsakat störningar i produktion och därtill försämrat leveransprecisionen till kund. Studien visar liknande faktorer under den militära konflikten, där leveranspålitligheten förvärrats och fortsatt påverkat produktionskapaciteten, vilket förväntas att försämra leveransprecisionen till kund ytterligare. Samtliga konsekvenser har orsakat att andra metoder än Just-in-time (JIT) bör tillämpas under sådana kristider, samt att det även krävs en annan syn på kapitalbindning. Trots detta har fallföretaget klarat sig undan relativt bra under pandemin tack vare större säkerhetslager, ökad standardisering och genom en innovativ åtgärd att montera på stödramar.  Studiens slutsats tyder på att motståndskraftiga försörjningskedjor och innovativt tänkande kan leda till lindrigare konsekvenser av både en pandemi och en militär konflikt, dessa är några av de teoretiska bidrag som presenteras. Vidare studier föreslås inom liknande branscher för att påvisa ökad generaliserbarhet.

Resilient Supply Chains : A Framework to Position Vendor Managed Inventory Digital Solutions and Enhance Resilience of Supply Chains After Disruptions

MEYER, DANIEL January 2020 (has links)
We live in an era where markets are more dynamic and the product life cycle is shorter, an era where concepts such as smart manufacturing and mass customization form part of daily life in industries and where consumption rates of products and services are rising. All these result in more dynamic, global, complex and fragile supply chains. Disruptions are negative impacts on business continuity in companies and when a supply chain is disrupted there is only one way to tackle the challenges originated and is the ability to be resilient. Based on a systematic literature review, this thesis lay out a framework to position Vendor Managed Inventory digital solutions in order to provide full visibility in the supply chains, and enhance agility and flexibility skill sets in the organizations to be resilient after massive disruptions such as the COVID-19. The conclusions of this work provide a positive outlook of the capabilities of VMI solutions to create more resilient supply chains. / Vi lever i en era där marknader är mer dynamiska och produkters livscykel kortare. En era där koncept som smart tillverkning och mass-anpassning är en del av dagliga livet i industrier och där konsumtionsnivåer av produkter och tjänster ökar. Allt detta resulterar i mer dynamiska, globala, komplexa och känsliga försörjningskedjor. Störningar påverkar kontinuiteten i verksamheten negativt hos företag och när en försörjningskedja påverkas av störningar finns det bara ett sätt att hantera utmaningarna som uppstår och det är genom förmågan att vara motståndskraftig. Baserad på systematisk litteratursökning, lägger denna avhandling fram ramverk för att positionera Vendor Managed Inventory digitala lösningar för att förse full synlighet i distributionskedjan och förbättra rörlighetens och flexibilitetens förmågor i organisationerna för att bli mera uthållig efter massiva störningar som COVID-19. Slutsatserna av detta arbete ger en positiv syn på möjligheterna för VMI-lösningar för att skapa mer motståndskraftiga försörjningskedjor.
