    Disruptions in global supply chains can severely impact the availability of medical equip- ment. Additive manufacturing (AM) presents a potential solution for the on-demand, decentralised production of critical medical parts. This master’s thesis investigates the current capabilities of AM for medical equipment manufacturing and what role AM could have in improving the supply chain resilience of medical equipment during a cri- sis. A comprehensive literature review of AM capabilities for medical equipment and areas surrounding the implementation of AM in healthcare, along with data collection through 17 semi-structured interviews with personnel from hospital 3D units and AM companies were conducted. The results of this study suggest that AM capabilities can be used to produce certain critical medical equipment to improve healthcare resilience. Furthermore, AM was found to enable a decentralised manufacturing structure that can further be used to improve resilience toward supply disruptions. This presents an opportunity to create a national collaboration to develop, manufacture and deliver critical items at shorter lead times and increase supply chain robustness. On this ba- sis, this study presents a recommendation to map the existing AM capabilities and production sites and establish collaborations between 3D units and AM companies to manage decentralised manufacturing at various scales effectively. Given the novelty of AM in medical equipment and the limited research that has been conducted in this field, further research is needed to better understand AM’s capabilities and factors for a successful implementation.

    More and more firms are adopting data-driven practices, where decisions are made efficiently and with high accuracy by relying on data. This requires a data-driven culture, that supports and encourages the use of data for decision making. This master’s thesis explores the success factors and challenges in implementing a data-driven culture within a firm with heterogeneous operations, focusing on the Swedish airport operator Swedavia. Through a case study, the research compares barriers and enablers for a data-driven culture from theory with identified factors at the case company. The factors are presented in seven areas: management & leadership, resistance to change, vision & strategy, skills & competence, data management & technology, culture & communication, and results measuring & incentives. The result is that the challenges and success factors found at the firm aligns with factors found in theory to a high degree. Some prominent challenges that were found at the case company include lack of a tangible data strategy, lack of data literacy, and missing data governance practices. Opportunities that were identified include top management commitment, a fact- based mindset, and data democratization. Some factors were identified at Swedavia that has not been discussed in previous research. For instance, Swedavia has success factors related to collaboration with other airports and multi-competence among employees, which are not covered in existing literature. Conversely, barriers such as inter-functional communication issues, limited access to computers for operational level employees, and a perception of older coworkers being reluctant to adapt to new practices present challenges that are also less discussed in theory. In addition to contributing with empirical depth to existing literature, this thesis provides actionable recommendations for building a data-driven culture at Swedavia and similar organizations. These recommendations include ensuring clear commitment from both top and middle management, formulating and effectively communicating a data strategy and vision, building robust data governance practices, and promoting cross-functional collaboration.

    Navigating the Post-Industrial Recyclate Landscape Policy Implications, Market Dynamics, and Allocation Methodologies in Life Cycle Assessment
    (2024) Gascon Rudin, Greta; Brantebäck, Daniel; Chalmers tekniska högskola / Institutionen för teknikens ekonomi och organisation; Chalmers University of Technology / Department of Technology Management and Economics; Janssen, Mathias; Bergfors, Fredrik
    This thesis explores the landscape of post-industrial recyclates (PIR), investigating policy, market trends, environmental impact, and life cycle assessment (LCA) allocation methods. The study takes the perspective of Borealis, a prominent player in the petrochemical industry, with a special focus on two of their recycling plants located in Germany and Austria. The policy analysis evaluates existing policies regarding PIR alongside a foresightbased scenario analysis. Findings reveal an absence of EU policy supporting PIR, contrasting with the abundance of policy support for post-consumer recyclates. The absence of policy support for PIR is likely due to its economic viability without such support, suggesting that current policy norms will persist. This sentiment is echoed by the scenario analysis, where no scenario indicated that PIR would require policy intervention to remain competitive in the market. The market analysis, which focused on the German market, identified younger demographics as key drivers of sustainable consumption, offering opportunities for PIR integration in sectors such as cosmetics, technology, and pet-related products. Additionally, consumers tend to consider the environmental impact of their purchases more when investing in expensive, long-lasting items, making furniture and household equipment promising markets. The analysis also explored the German automotive industry, where demand for recyclates is rising, although impending EU regulation may limit PIR’s potential. The LCA findings revealed a lower environmental impact for PIR compared to virgin polypropylene (PP) across 14 out of 16 impact categories. System expansion allocation yielded distinct outcomes as it accounts for the emissions avoided when substituting virgin PP with PIR. Conversely, other methods - mass allocation, economic allocation and the cut-off approach - yield similar results. While both mass and economic allocation were deemed appropriate, mass allocation emerges as the optimal choice, better reflecting real-world drivers behind plastic production and waste generation.

    Exploration of Different Production Flow Setups in Manufacturing Facilities Evaluating Production Scenarios for SKFs Roller Production
    (2024) Pettersson, Joel; Lorentzon, Max; Chalmers tekniska högskola / Institutionen för teknikens ekonomi och organisation; Chalmers University of Technology / Department of Technology Management and Economics; Medbo, Per; Medbo, Per
    This thesis investigates the optimization of production systems at SKF, a global leader in the manufacturing of bearings, focusing specifically on roller manufacturing in Gothenburg, Sweden. Given the rapid advancements in industrial manufacturing SKF seeks to increase the efficiency of their roller production. This study assesses two contrasting production scenarios, Simplified Flow and Flexible Flow, to determine which aligns best with SKF’s strategic objectives and the inherent challenges of the production environment. The primary aim is to evaluate these systems against key performance indicators, ultimately aiding SKF in refining its production processes. Research Questions (RQ): 1. What does the current situation look like for roller manufacturing at SKF? This question seeks to describe the baseline operations and existing challenges within SKF’s roller production. A VSM was conducted to answer RQ1. 2. What problem areas can be identified connected to the current situation? This focuses on pinpointing specific issues that could be addressed by changes in the production system. RQ2 was answered by identifying problem areas derived from interviews, observations, and the VSM where 6 problem areas were identified. 3. What are the main differences between the two proposed production scenarios and how do they manage the identified problem areas? This question compares the two production scenarios in detail, examining how each manages the identified problem areas. The Simplified Flow focuses on flow efficiency whilst Flexible Flow focuses on resource efficiency. 4. Which of the two proposed production scenarios for SRB rollers is most suitable for SKF? The final question aims to conclude which production scenario best fits the strategic and operational goals of SKF. RQ4, by combining the results from an MCDA analysis and how the respective scenario manages the identified problems, resulted in a recommendation to implement, and move toward the Simplified Flow along with aspects taken from the Flexible Flow. This research utilizes a mixed-method approach, incorporating both qualitative and quantitative data from interviews, observations, and internal documents. Through analysis framed by a literature review in production systems, this study contributes to the decision-making process at SKF and extends practical implications for the broader field of industrial manufacturing.
