New business models in the agrifood system: from theory to practice  

Agricultural businesses operate in a rapidly changing environment, challenging the conventional way of production. The concept of a business model (BM) is frequently mentioned in both scientific literature and practice as a way to address these challenges and to seize opportunities arising from a changing environment. However, for various reasons, it is unclear how useful the concept, along with the many tools and theoretical frameworks, is for this transition in agriculture. The overall aim of this PhD is to establish a connection between academic theory on business models and agricultural practice, examining how theoretical insights can facilitate the implementation of business model changes within the agricultural sector. The concept’s usability was qualitatively investigated through interviews and field observations, following two parallel paths: one explored existing literature on business models to identify methods addressing key challenges, while the other investigated the practical information needs in agriculture using the VerdienWijzer, a prototype of a decision support tool on business models developed during the PhD.
The doctoral research shows that BM change in agriculture is shaped by the interaction of three types of influencing factors (drivers, facilitating/hindering factors, and factors that affect the coherence within the business model or between the business model and its environment) interacting at four different levels (the farmer, the farm, the industry, and the macro-environment). The role or type of influence of each factor is determined by the characteristics of the situation for a change. The Holistic Analysis of Business Model Change (H-ABC) framework, developed during this doctoral research, enables the identification of those three types of influencing factors and allows a comprehensive study of a change of a business model.
Farmers today, often unconsciously, consider both internal and external factors when analysing business model changes. The H-ABC framework makes it possible to clarify, visualise, and include these factors in the analysis. However, farmers currently lack the capacity to absorb and effectively use information about business models. This research identifies five information needs, ranging from the need for inspiration about possible changes to the need for guidance in implementing the change. Finally, implications of this research are given for various stakeholders in the agri-food system regarding the use of the business model concept in their practice.

A Critical Look at an IT Governance Framework: The COBIT Case

The starting point of our research was the contradictory observation that in today’s society—highly dependent on Information and Technology (IT)—small and large IT-related problems continue to occur, despite the existence of numerous IT good practices. This led us to suspect that the so-called ‘good practices’ are either not genuinely good, or they are not being properly practised.
We selected one such good practices framework – COBIT (Control Objectives for Information & Related Technology) —and took a critical view at its intrinsic quality.
The first problem we faced was that COBIT is barely researchable in its current form, i.e. various publications totalling over a thousand pages, without a clear and accessible model. We therefore first distilled the key concepts from the COBIT publications and describe the relationships between those concepts in a concise conceptual model. We developed this model for both COBIT 5 and COBIT 2019 (the current version). This conceptual model made COBIT researchable, and it enabled us to construct a well-structured research agenda, which should facilitate and encourage further academic study.
In a next step we compared the COBIT conceptual model with a selection of other widely used Information Systems theories, in order to identify potential improvements to COBIT. This comparison with seven other theories yielded a significant number of suggestions for improving COBIT, all of which were incorporated into the research agenda and in a proposed conceptual model for a potential future COBIT version.
Subsequently, we investigated a (small) selection of topics from the research agenda. This produced mixed results. A prioritization mechanism from COBIT 5 proved inadequate; a new concept—design factors—from COBIT 2019 was found to be sound. But the most significant finding was that the performance measurement system in COBIT was inconsistent with its own design principles. According to COBIT, an IT Governance System consists of a holistic set of interrelated components, including processes, structures, information, procedures, and more. However, the performance measurement system only evaluated the performance of processes, ignoring the other components of the governance system.
In the most substantial part of our research, we addressed this gap by designing a maturity model for organisational structures, a reference model for information quality, and a maturity model for information quality. These models were developed using the Design Science methodology, involving iterative refinement through expert panels. Additionally, we created a prototype tool to support the practical application of the artefacts we developed.

Spatiotemporal environmental techno-economic assessments and optimizations of advanced liquid transport biofuel production

The transition to a low-carbon economy has highlighted the need for sustainable energy sources, especially in the transport sector, which remains one of the most challenging to decarbonize. Advanced biofuels have emerged as a promising alternative, particularly in hard-to-abate transport modes such as aviation and heavy-duty vehicles, where electrification remains technologically challenging. However, high production costs, feedstock availability constraints, environmental uncertainties, and the inconsistent and volatile policy environment pose major barriers to their large-scale commercial adoption. Addressing these challenges requires comprehensive assessments of the economic and environmental performance of advanced biofuels technologies to guide decision-making in the energy transition of the transport sector.
Through the integration of geospatial and temporal dimensions within assessment and optimization approaches, this dissertation advances state-of-the-art methodologies for evaluating the economic and environmental performance of advanced biofuels production. The findings highlight the need for robust assessments that provide a more holistic perspective on advanced biofuel deployment, which can be a valuable decision-support tool for policymakers, industry stakeholders and researchers. As the world shifts rapidly towards a more sustainable energy future, this research aims to contribute to more informed strategies that effectively support this transition.

Customized airline offer management: solving the assortment problem through multi-dimensional segmentation

This dissertation develops a novel solution for customized airline offer management with the aim to combine viability, usability, and feasibility. The solution is tested on real data from a major network airline. It expands the existing academic literature and practical applications as it suggests a cost-effective and understandable way for airlines to significantly improve the prediction accuracy of customer choice models without the need for complex models, using existing data and simple forecasts. The research shows that high-dimensional and data-driven segmentation, potentially aided by machine learning to solve data sparsity, can be combined with the traceability of discrete choice models.

This implies airlines do not need complex machine learning models to improve the prediction accuracy of which specific product a specific customer will likely purchase. However, airlines should use information they already have in a customer search. Because the data is already available, this is a cost-effective way for airlines to significantly improve the prediction accuracy of their customer choice models with 99.9% confidence. The proposed offer management system is data-driven, can respond to searches in real-time, and is designed in modules for gradual embedding into existing processes, workflows, and system. Also, it is built in a way that it both works with existing revenue/offer management systems as well as innovations like continuous pricing and new distribution capabilities that are strategic priorities for airlines.

Ports at the crossroads of the energy transition: navigating shifts in energy flows - Scenarios and strategic implications

The global transition toward a low-carbon energy system represents a critical challenge for the 21st century, driven by the urgent need to reduce greenhouse gas emissions and comply with increasingly stringent climate policies. Despite significant advancements in renewable energy deployment, fossil fuels continue to dominate global energy consumption, illustrating the urgent need for accelerating sustainable energy sources. This dissertation explores the strategic role of European liquid bulk ports in the energy transition, especially for importing, storing and handling hydrogen and ammonia. The research investigates how differing European energy transition scenarios influence storage investment needs and the alignment of port objectives with a long-term hydrogen economy. Using a scenario-based methodology, it quantifies required storage capacity, investment needs and spatial demands across major European ports, and examines how hydrogen adoption aligns with port objectives. Based on literature reviews, scenario modeling, cost calculations and expert interviews, the study finds differences in infrastructure needs depending on the energy scenario. Moreover, the research reveals strong stakeholder consensus on the critical importance of hydrogen adoption for achieving environmental stewardship and economic competitiveness objectives in port governance. This alignment suggests that ports are well-positioned to lead infrastructure investments through collaboration that underpin Europe’s hydrogen ambitions while also facing challenges such as regulations and integrating emerging technologies. Ultimately, this dissertation provides actionable recommendations for policymakers and port authorities to accelerate infrastructure development supporting a resilient, sustainable, competitive energy future. Future research should address geopolitical factors, environmental impacts of ammonia logistics and the scalability of renewable energy carrier infrastructure to investigate hydrogen-powered maritime hubs.

Assessing the Willingness of Kenyan Farmers and Consumers to Transition Towards Sustainable Food Systems 

In the face of escalating challenges related to climate change, food security, and environmental sustainability, fostering resilient and sustainable food systems is critical, particularly in Sub-Saharan Africa. This dissertation examines the perspectives and preferences of Kenyan food value chain actors – focusing primarily on farmers and consumers – toward sustainable food systems. First, a systematic literature review highlights the diverse and context-specific factors influencing Sub-Saharan African farmers' adoption of climate-smart agriculture, identifying key barriers (e.g., reliance on off-farm income) and drivers (e.g., education level, training, access to credit, and others). Subsequently, using Q-methodology, four distinct stakeholder perspectives on sustainable food value chains in Kenya are identified, reflecting differing priorities across economic, environmental, and social dimensions. Building on these insights, two Choice Experiments were conducted to quantify the preferences of Kenyan farmers and consumers regarding sustainability-related attributes in the food system. The results reveal overlapping priorities between farmers and consumers, particularly concerning the reduction of pesticide use and the improvement of farmers’ working conditions. By connecting the supply and demand sides of the value chain, this research provides practical recommendations for designing policies and interventions that promote sustainable agricultural practices and resilient food systems in Kenya. Overall, the findings underscore the necessity of context-specific, inclusive strategies that align the motivations of key value chain actors to drive systemic change.

Design, implementation and use of effective performance measurement systems for defense and security organizations

Defence organizations face increasing challenges in adapting to the Volatile, Uncertain, Complex, and Ambiguous (VUCA) environment. Currently, hybrid threats demand the integration of civilian and military resources and efforts to enhance resilience, requiring collaboration across diverse stakeholders. Despite this need to engage with - and demonstrate performance towards - a wide array of stakeholders, existing performance management (PM) systems within defence fail to align with strategic objectives and address stakeholder complexity effectively. Notably, frameworks like the Balanced Scorecard prioritize internal efficiency, thereby neglecting the multidimensional nature of defence activities and the need for multi-stakeholder integration. Given the performance and stakeholder-related gaps, the critical question addressed within this manuscript is: How can defence organisations demonstrate performance towards the complex set of stakeholders within an increasingly demanding environment?

Metaheuristics for Assembly Line Feeding Optimization and Tow Train Routing in the Automotive Industry

The automotive industry, a cornerstone of modern economies, is under increasing pressure to improve production efficiency amidst rising system complexity, sustainability requirements, and the demands of just-in-time (JIT) manufacturing. This dissertation addresses critical optimization problems in this context, focusing on tow train-based assembly line feeding and routing — a key internal logistics function where smart planning can significantly reduce costs and ensure timely, disruption-free operations.
The first part of the dissertation tackles the Assembly Line Feeding Problem (ALFP), where tow trains deliver parts to workstations under strict timing and load constraints. To address this inherently complex and computationally challenging problem, a Variable Neighborhood Search (VNS) algorithm is proposed within the framework of the Split Delivery Vehicle Routing Problem (SDVRP).This method reduces total travel distance and the number of required vehicles while managing trade-offs between cycle times, split deliveries, and transport volume in a multi-objective context.
The second part investigates conflict-free tow train routing in grid-based production environments. In JIT systems, route conflicts lead to delays and safety issues. A novel approach is introduced that models the layout as a grid of “pixels” to detect potential collisions. Paths are computed using the A-star (A*) algorithm, and optimized through a Simulated Annealing (SA) heuristic. A dedicated Conflict Detection Algorithm (CDA) resolves potential collisions using preemptive avoidance strategies, ensuring safe and uninterrupted flow.
The third contribution addresses tow train routing in narrow-aisle environments, where vehicles cannot reverse and risk blocking each other. A pixel-based grid is again employed for spatial modeling, and shortest paths are calculated using Dijkstra’s algorithm. The routing problem is formulated as a Generalized Vehicle Routing Problem (GVRP), and solved using an SA-based heuristic enhanced with problem-specific neighborhood operators. A blocking detection and avoidance algorithm ensures that deadlocks are avoided, maintaining the system’s throughput.
Together, these contributions combine advanced metaheuristic techniques, conflict resolution mechanisms, and routing optimization models. The findings offer scalable and practically implementable strategies to address real-world challenges in modern automotive production environments and contribute to the evolving field of smart manufacturing logistics

Empirical Market Microstructure Essays in Over-the-Counter Markets 

The findings presented in this dissertation significantly enhance our understanding of OTC sovereign bond markets, addressing a crucial gap in academic research due to the scarcity of high-quality publicly available data. Through pioneering trade-level datasets on the UK sovereign bond market, this research offers comprehensive summary statistics that shed light on the overall market and individual participant behaviour. It further delves into the roles of prevalent OTC market frictions—inventory, search, and bargaining—which are instrumental in the liquidity deterioration experienced in the UK sovereign bond market during the COVID-19 pandemic. This analysis clarifies how these frictions impact market resilience and identifies potential vulnerabilities. Further, the dissertation evaluates the effects of post-trade transparency on market quality, systematically exploring how transparency influences transaction costs and contributes to pricing efficiency in sovereign bond markets. These insights have academic and policy implications, offering empirical evidence that can inform future regulatory frameworks and market operations to foster more efficient and resilient financial markets

As above, so below? A multilevel approach to the Job-Demands Resources Model - David Stuer (24/03/2025)

As above, so below? A multilevel approach to the Job-Demands Resources Model

The dissertation extends the Job Demands-Resources (JDR) model in two key directions: the intra-individual level (how job demands and resources fluctuate over time) and the supra-individual level (how they are distributed within teams).
At the intra-individual level, a dynamic systems perspective is introduced, differentiating between trait and state job demands and resources and incorporating patterns of change over time, such as variability and attractor strength. At the team level, the research explores disparities in job demands and resources, analyzing how unequal distributions influence employee outcomes.
Conceptually, the dissertation advances the JDR model by integrating emergent properties across different levels of measurement and incorporating configural constructs, drawing on diversity research to examine how disparities in job characteristics shape workplace experiences. Methodologically, the research applies multilevel modeling to simultaneously assess job demands and resources across different levels (intra-individual, individual, and team level). It introduces novel measures for emergent concepts and investigates interactions, ensuring a systemic and integrated approach to understanding job demands, resources, and their organizational impact.
By combining conceptual advancements with rigorous methodological approaches, this dissertation provides a deeper and more dynamic perspective on job demands and resources.

Risk assessment of supply chain management during COVID19 pandemic and inventory classification using MCDM tools

This dissertation focuses on the risk assessment of supply chain management during the COVID-19 pandemic and inventory classification using Multi-Criteria Decision Making (MCDM) tools. It comprises three research articles. In the first article, we introduce a novel MCDM approach called Fuzzy VIKORSort. This method is utilized to classify various economic sectors into predefined groups (High, Moderate, Low) based on the disruptions in the global and regional supply chains due to the COVID-19 pandemic. We validate our methodology using the case of Pakistan. In the second article, we propose an enhanced visualization method based on MCDM called VIKOR-GAIA. To implement this visualization approach, we use a case study of supply chain disruptions in perishable food items. Additionally, we conduct a comparative analysis with an existing visualization based on the MCDM approach to demonstrate the effectiveness of our proposed method. In the third article, a new method called VIKOR Fuzzy Sort is proposed to address the Multi-Criteria Inventory Classification (MCIC) problem. This methodology facilitates the classification of different inventory items based on their inherent characteristics' resemblance to neighboring classes during the sorting process. The proposed methodologies in this dissertation will assist policymakers and practitioners in addressing various complex decision problems. Additionally, they will make a meaningful contribution to scholarly work.

Macroeconomic Policy, Household Heterogeneity, and the Labor Market

This dissertation contributes to the understanding of fiscal and monetary policy aimed at stimulating economic activity during recessions and maintaining price stability.  With the resurgence of fiscal policy as a crucial stabilization tool post-Great Recession and the recent shift to higher interest rates following an extended period of historically low rates, a deep understanding of fiscal and monetary policy is vital. Empirical research of labor markets and the development of theoretical macroeconomic models that analyze fiscal and monetary policy contribute to this understanding. The results reveal significant changes in labor market conditions, with increased employer market power and heterogeneous labor supply elasticities, and underscore the need to consider these factors in policy decisions. Additionally, a novel fiscal policy transmission channel can be observed through countercyclical monopsony power. Finally, the analysis of New Keynesian models discovers new insights into the Taylor principle and determinacy issues depending on household heterogeneity and households’ labor supply preferences. Overall, this thesis underscores the necessity of current empirical analysis of the labor market and updated models for macroeconomic policy analysis.

AI-powered solutions assessment in port and maritime sector

The digitalization of port and maritime, particularly through the adoption of AI-powered solutions, is a major trend these days. However, this research identifies gaps in the literature, including the lack of a consistent approach to distinguishing AI initiatives and quantifying their costs and benefits. To address these gaps, this PhD thesis employs a mixed-method approach, combining both desk and empirical research. This study develops two assessment models: an AI typology to differentiate AI solutions and a cost-benefit framework to conduct economic analyses of AI solutions. Furthermore, the research identifies a typology of 30 AI initiatives and ranks them based on deployment complexity, considering their application domains. Secondly, three detailed economic analyses are conducted at two implementation levels: micro and macro. The first analysis explores the use of AI to predict truck ETAs for a trucking company. The findings indicate that the truck ETA prediction project offers comparable profitability under two conditions: trucking companies with legacy systems but with potential for revenue growth through AI adoption or trucking companies without the chance for revenue growth but can avoid technical integration costs. However, the project becomes highly cost-effective when revenue increases, and technical integration is not required. The second analysis assesses the benefits of AI-assisted data entry for logistics companies when processing transport orders. The economic analysis reveals that modifying IT system architecture to incorporate AI-assisted data entry is not cost-effective for companies with low transaction volumes. However, horizontal collaboration can reduce organizational integration costs, typically 1% to 7% of total solution implementation costs. The third analysis evaluates an AI-powered solution to optimize the scheduling of tugboats and dock pilots within the lock. It highlights the trade-offs between incorporating fairness in task allocation and achieving cost savings through AI-driven optimization. Including fairness as a goal reduces cost savings, reflecting the social integration costs, which account for 31% and 23% of cost savings for tugboat and pilotage companies, respectively. Additionally, a gain-sharing scenario minimizes benefit losses among port stakeholders, reducing overall losses by 3.5% to promote vertical collaboration. Overall, this dissertation offers valuable insights into AI assessment in the port and maritime sectors, contributing to scholars and industry.

Unravelling D&D within the maritime ecosystem and its influence on IWT in port-hinterland supply chains - Katrien Storms (07/02/2025)

Unravelling D&D within the maritime ecosystem and its influence on IWT in port-hinterland supply chains

The use of intermodal inland waterway transport (IWT) is a key European strategy to move towards climate-neutral transport. However, challenges such as COVID-19, extreme Rhine water levels, and geopolitical disruptions complicate the shift from road to IWT. These disruptions often result in additional costs, known as demurrage and detention (D&D).

This dissertation researches the impact of D&D practices on IWT within Europe’s port-hinterland supply chain. Using a SARIMAX modeling, it forecasts IWT container volumes on the Rhine and highlights the potential impact of disruptions on IWT recovery. Findings from surveys, discussions, and legal analyses reveal inefficiencies in D&D practices and propose solutions such as extended free time for IWT, digitalization, and improved negotiation strategies. Cost analyses show that D&D fees can exceed the shipping lines’ opportunity costs as time passes, suggesting their role as a revenue stream. Nevertheless, shippers can leverage D&D into their storage strategies to optimize costs. Furthermore, D&D and terminal dwell times significantly influence IWT's modal share. Consequently, addressing D&D is important in making a shift towards more sustainable and efficient hinterland transport.

How the Nutri-Score affects consumers and manufacturers: A focus on consumers’ choices and manufacturers’ reformulation efforts

Imagine you are standing in the supermarket. As you gaze at the rack of breakfast cereals, you might feel overwhelmed by the numerous alternatives presented to you. How do you choose what to buy? The Nutri-Score was developed to simplify this decision by aiding consumers to compare products’ healthiness. As previous research demonstrates its understandability, attention-grabbing properties, and mostly positive effects on purchase intention and choice, the European Union has considered adopting it as the official European label as part of their Farm-To-Fork strategy.
Nevertheless, not all countries are unequivocally in favour of this label; the same holds true for companies, and even experts and researchers, who cite mixed findings and several evidence gaps. This has complicated the decision of the European Commission and led to postponing their harmonized labelling efforts.
Against this backdrop, this dissertation focusses on strengthening the available evidence by addressing five key gaps. It explores the Nutri-Score’s effect outside of controlled environments, its impact on multi-attribute product choices, the heterogeneity in consumers’ preferences for the label, its implementation in online supermarkets, and the efforts undertaken by food manufacturers to engage in Nutri-Score-driven product reformulations.
Employing a range of methodologies - including a naturalistic field experiment, discrete choice modelling, a randomized controlled trial, and retrospective observational study – this work provides fresh insights into the Nutri-Score’s effectiveness. By extending our knowledge and insights on the multifaceted puzzle that surrounds the Nutri-Score, this thesis contributes to a robust evidence base that will eventually enable the European Commission to make well-informed and evidence-driven decisions on harmonized labelling efforts.

Navigating Endgames: Conceptualization, Strategies and Successful Turnarounds 

The pace of technological change and digital transformation is accelerating, leading to the emergence of new industries as others decline. Responding to this phenomenon, this PhD thesis explores the challenges of industry decline, endgames and organizational turnarounds. I draw on a rich theoretical foundation and empirical evidence to identify the strategies firms can follow to navigate these challenges.

This PhD thesis is structured around three studies researching the social construction of endgames, how strategy is adapted within an endgame and how firms can achieve successful turnarounds. In the first study, I use a fictional institutionalist perspective to show how endgames are socially constructed, shedding light on the dynamic interplay of industry actors’ fictional expectations and the subsequent strategies they chose as an endgame diffuses through an industry. The second study investigates the patterns of strategic change in endgames and introduces a dialectical model that conceptualize the dynamics of organizational responses to industry decline. The last study focuses on organizational turnarounds as organizations initiate turnaround efforts to recover from prolonged decline in an endgame. This study uses a qualitative meta-analysis of turnaround cases to identify the underlying mechanisms and temporal sequences of successful recovery efforts. The four distinct process archetypes that this study identifies contributes both theoretical insights for researchers and practical insights for managers navigating turnaround scenarios. Together, these three studies provide a detailed understanding of endgames, from how endgames are conceptualized to which organizational strategies firms follow in endgames to the archetypes of organizational turnarounds that firms use to recover from prolonged decline during an endgame.

Overall, this thesis contributes theoretically and practically to the fields of strategic management and organizational studies. I provide a nuanced understanding of how organizations can navigate the tumultuous waters of decline, adapt to changing industry landscapes and orchestrate successful turnarounds in the face of adversity.
