51	Enhancing Supply Chain Resilience : A Digital Twin Conceptual Model of Supplier Selection Factors Impacting Supply Chain Resilience / Att öka motståndskraften i en leveranskedja : En konceptuell modell för digital twins i leverantörsvalsprocessen Khan, Anika Subah, Seger, Carlos January 2024 (has links) In the context of recent global disruptions, enhancing supply chain resilience has become critical for businesses. This thesis proposes a conceptual model for implementing a Digital Twin (DT) in the supplier selection process to enhance supply chain resilience. By integrating real-time monitoring, scenario testing, and collaborative platforms, the model addresses three main pillars of supply chain resilience: SC Visibility, SC Agility, and SC Collaboration. The research employs a systematic literature review for the identification of the three pillars and the development of the Supplier Management Digital Twin (SMDT) framework. The findings suggest that the DT can significantly improve supply chain visibility through continuous KPI monitoring, enhance agility by simulating disruption scenarios, and foster collaboration via shared data platforms. Additionally, a case study on the supplier selection process was conducted, through semi-structured interviews, that when applied through the SMDT framework showcased what factors in the supplier selection process that can be applied to a DT. This study contributes to the theoretical understanding of DTs in Supply Chain Management and offers practical insights for managers seeking to enhance resilience to their supply chain. Future research could explore greater insights from DT experts and implementation through simulation models to further validate and expand the model's utility. / I samband med dagens globala störningar har förbättringen av leveranskedjans motståndskraft blivit mer kritiskt än någonsin för världens företag. Denna rapport föreslår en konceptuell modell för att implementera en Digital Tvilling (DT) i leverantörsvalprocessen för att stärka leveranskedjans motståndskraft. Genom att integrera realtidsövervakning, scenariotestning och samarbetsplattformar adresserar modellen tre grundpelare av leveranskedjans motståndskraft: Synlighet, Agilitet och Samarbete. Rapporten använder en systematisk litteraturstude för att identifiera de tre grundpelarna samt utveckla ett ramverk för en DT. Resultaten tyder på att en DT avsevärt kan förbättra leveranskedjans synlighet genom kontinuerlig KPI-övervakning, öka agiliteten genom att simulera scenarier av olika störningar och främja samarbetet via en delad plattform. Dessutom genomfördes en fallstudie av leverantörvalsprocessen genom semi-strukturerade intervjuer, vilket via en analys av Leverantörshanterings DT-ramverket visar vilka faktorer i leverantörvalsprocessen som kan tillämpas på en DT. Denna studie bidrar till den teoretiska kunskapen av DT:ar i leveranskedjehantering och erbjuder praktiska insikter för chefer som söker att öka motståndskraften i sin leveranskedja. Framtida forskning kan utforska djupare insikter från DT-experter och testa implementering genom simuleringsmodeller för att ytterligare validera och utöka modellens användbarhet.

54	Adapting to Extreme Weather Events : - Addressing Flood Risks Through Planning and Policy in Namibia Licke, Tim January 2023 (has links) This master thesis investigates planning initiatives to address extreme weather events' impacts, specifically focusing on floods in Namibia. The study highlights the significance of such events in the context of global climate change, emphasising their adverse effects on livelihoods, particularly in rural communities and informal settlements. The research aims to evaluate existing strategic plans and policies in Namibia concerning extreme weather events and to examine the extent to which such events are considered when planning initiatives are implemented. Based on the theoretical framework of implementation theory, the study adopts a mixed-method research approach. Document analysis is employed to examine policies and plans related to planning in Namibia, while semi-structured interviews with key informants provide insights into the stakeholders' perspectives. A comprehensive understanding of the subject is achieved by comparing and validating findings from both methods. The results of the study reveal several approaches in current strategic plans and policies regarding the consideration of floods in Namibia. While several documents acknowledge the threat of floods and outline responsibilities and measures, there is a lack of comprehensive and coordinated approaches. The study highlights the need for a more integrated approach and increased alignment among different levels of planning documents. Furthermore, the research shows that the implementation of planning initiatives in Namibia is a centralised process overseen by the Ministry of Urban and Regional Development, with a limited focus on flooding beyond urban areas. The study identifies key challenges in implementing climate change adaptation strategies and projects in Namibia, including limited communication and coordination between actors, difficulties in accessing planning laws, plans and policies, and the centralisation of planning at the national level. However, opportunities for improvement are also recognised, such as enhanced local autonomy in planning processes and the integration of local and indigenous knowledge. Overall, the findings underscore the importance of addressing the impact of extreme weather events, particularly floods, through comprehensive and coordinated planning initiatives in Namibia. The study provides valuable insights for policymakers and planners in developing effective strategies to mitigate and adapt to the effects of climate change in the country.

56	Digitala leveranskedjor och höga krav på informationssäkerhet : Implikationer för att stärka Sveriges digitala motståndskraft / Digital supply chains and high requirements for information security : Implications for strengthening Sweden's digital resilience Dohrendorf, Christian January 2024 (has links) Syftet med uppsatsen är att öka kunskapen kring organisationers och kringliggande aktörers förmåga att stärka den digitala motståndskraften i digitala leveranskedjor genom införande av ett omfattande regelverk. Uppsatsen beskriver hur tillkommande regelverk med höga krav på informationssäkerhet inom de digitala leveranskedjorna påverkar en enskild organisation. Uppsatsen beskriver även implikationerna ur ett övergripande systemperspektiv. Utifrån införandet av Digital Operational Resilience Act (DORA) beskrivs både potentiella hinder som riskerar hämma Sveriges digitala motståndskraft och de möjliggörande åtgärder som leder till att Sveriges digitala motståndskraft stärks. Uppsatsen identifierar genom en fallstudie ett antal hinder som enskilda organisationer bör beakta, men som även har stora beroenden till andra kringliggande aktörer och systemet i sin helhet. Uppsatsen beskriver att det kan uppstå följdeffekter som lätt leder till oönskade effekter. Komplexitetshöjningen genom tillkommande regelverk kräver medvetna handlingar av ett stort antal aktörer för att undvika att hinder blir alltför hämmande och därmed hindrande för Sveriges digitala motståndskraft. Speciellt mindre leverantörers situation lyfts som problematisk i sammanhanget. Uppsatsen identifierar behovet av en holistisk inställning som nödvändig för att kunna skapa utrymme för medvetna handlingar. Komplexitetshöjningen som tillkommande regelverk innebär behöver hanteras både internt inom en enskild organisation och genom externa samarbeten. Uppsatsen beskriver att identifierade möjliggörande åtgärder inte enbart bör värderas utifrån direkta effekter, utan även utifrån mer långsiktiga indirekta effekter och resurspåverkan i systemet. Först då finns det förutsättningar att genom medvetna handlingar uppnå positiv effekt och därmed stärka Sveriges digitala motståndskraft.

57	Supply Chain Resilience for SMEs : An exploration of buyer-supplier relationships and the role of inventory management Giss Ljungberg, Mathilda, Lindgren, Emma January 2024 (has links) An increase in global supply chain disruption, such as the Covid-19 pandemic, has exposed vulnerabilities in supply chains. This has caused a reassessment of current supply chain management practices and highlighted a need for more resilient approaches. Despite an increased focus on this research area, Small and Medium-sized Enterprises (SMEs) are further challenged. Current practices are not well suited for these kinds of firms as they face resource and operational constrains. SMEs tend to build resilience through safety stocks, which provide a buffer against disruptions. However, maintaining inventories can be costly and inefficient. Furthermore, supply chain relationships have shown to enable collaborative efforts and increase visibility in the chain, thereby improving resilience. In light of this, the research focuses on exploring the effect of buyer-supplier relationships on SMEs resilience and how inventory management can align with SMEs efforts to build resilience. For this, a qualitative approach was employed, involving a case study of a manufacturing firm in Sweden. Data were collected through semi-structured interviews with six employees and seven direct suppliers, along with observations and archival data. The findings highlight the importance of long-term relationships in fostering supply chain resilience (SCR), emphasizing the need for transparent communication and collaboration. Therefore, a managerial framework is provided to guide the assessment of these relationships fostering the resilient benefits of supplier relationships. Additionally, the findings indicate the need for SMEs to balance inventory management practices with risk mitigation efforts like dual sourcing. The research concludes by outlining the benefits and risk associated with buyer-supplier relationships, emphasizing the importance of internal structures, and how inventory management practices can enhance SCR for SMEs. / En ökning av globala störningar, såsom Covid-19-pandemin, har avslöjat sårbarheter i försörjningskedjor.

58	A Novel Approach to Youth Crime Prevention: Mindfulness Meditation Classes in South African Townships / A Novel Approach to Youth Crime Prevention : Mindfulness Meditation Classes in South African Townships Kneip, Katharina January 2020 (has links) Children growing up in poor areas with high crime rates are shown to easily get involved in violent actions and criminal gangs. In South Africa, despite considerable efforts to reduce youth delinquency, youth crime rates are still disturbingly high – specifically, in the townships of the Cape Flats. This paper points out an important aspect previously unaddressed by most youth crime prevention: the subconscious roots of youth crime. What if we could develop youth crime prevention programs that manage to impact the subconscious behavioral patterns of youth in high crime areas? This paper proposes a promising and cost-effective approach that has great potential to affect multipe causes of crime: mindfulness meditation. Built upon newest findings in Neuroscience, this paper suggests that mindfulness meditation classes are associated with a reduction in aggressive behavior, a risk factor for youth crime, and an increase in self-efficacy, a protective factor. The impact of mindfulness classes at a high school in Khayelitsha, a poor and violent-stricken township of Cape Town, is analyzed. Self-reported aggression and self-efficacy are measured via a psychometric survey questionnaire created from two well-tested and validated scales. Regression analyses of 384 survey answers provided mixed results. Whilst novice meditators were not associated with higher self-efficacy and lower aggression, long-term meditators performed better in several dimensions of self-efficacy and aggression, yet no significant relationship was found. Further research specifically needs to investigate the moderating effect of age (a proxy for psychological development) on meditation. This study aims to bridge the gap between the outdated paradigms of youth crime prevention and ancient wisdom via ground-breaking new evidence from the field of Neuroscience. This study furthermore hopes to point policy makers toward developing new, integrative and sustainable approaches to youth crime prevention – approaches that give back agency to our youth. / <p>Anders Westholm har inget med betygssättningen att göra annat än i rent formellt hänseende (examinator).
