    A resilience assessment model for dry bulk shipping supply chains: the case of the Ukraine grain corridor
    (Palgrave Macmillan Ltd, 2023) Karakas, Serkan; Kirmizi, Mehmet; Gencer, Huseyin; Cullinane, Kevin
    Maritime supply chains are critical elements in global freight movements, but they are vulnerable to interruption owing to various events, such as port disruptions, natural hazards and war-related risks. The Ukrainian-Russian war has proved to be a significant disruptor of maritime supply chains. However, under the United Nations grain corridor initiative, approximately 14 million tons of Ukrainian grain exports have been loaded in the first 6 months of its operation, clearly indicating the supply chain resilience present within the grain corridor. This suggests the need for an in-depth investigation of the internal characteristics and dynamics of the system. Hence, within the context of the grain corridor initiative, this study addresses the resilience of the dry bulk supply chain and its underlying 'dynamic capability' and inherent adaptability and responsiveness. A novel assessment model is proposed for addressing the role of tonnage flexibility. Accordingly, objective and subjective multi-criteria decision-making methods are employed in an integrated approach that incorporates the concept of resilience as embodied in the dimensions of density, demand, dispersion, diversity, and utilization. Moreover, the prompt and flexible response of dry bulk fleets to disruptive occurrences can be explained by the dynamic capabilities view. Perhaps counterintuitively, the results reveal that the Panamax vessel size category is the most significant for ensuring the recovery of maritime supply chains, while the small dry bulk size category is less important, despite its vital role and prevalence within the wider context of general Black Sea maritime transportation.

    Beyond technology: the role of stakeholder influence and organizational politics in ERP readiness
    (Emerald Group Publishing Ltd, 2025) Arslan, Aykut; Kirmizi, Mehmet; Karakas, Serkan; Kocaoglu, Batuhan
    PurposeThis study introduces a novel political lens to ERP readiness assessment, moving beyond technical checklists to reveal how stakeholder power dynamics shape pre-implementation success. Using a mixed-method design integrating DEMATEL and ANP, we identify causality and weightings among readiness factors as perceived by different stakeholder groups.Design/methodology/approachA mixed-method approach was adopted, integrating a systematic literature review with expert validation, followed by DEMATEL and Analytic Network Process (ANP) techniques. Data was collected from five stakeholder groups-project managers, ERP system managers, users, vendors, and consultants-to model causal relationships and stakeholder priorities across 13 ERP readiness dimensions.FindingsThe results demonstrate that readiness is not merely a static technical state but a dynamic outcome of political negotiation. Vision and Strategy emerged as the most causally influential dimension, while Project Manager and Team Competency received the highest stakeholder priority. High inter-group agreement (ICC = 0.988) underscores the shared understanding of politically salient readiness factors.Practical implicationsManagers are advised to incorporate stakeholder mapping, influence analysis, and political engagement strategies in readiness assessments. The proposed framework enables organizations to surface political risks early and align stakeholder interests, thereby increasing the likelihood of ERP success.Originality/valueThis study introduces a politically informed ERP readiness framework, grounded in Vroom's Expectancy Theory and Organizational Politics Theory. By extending traditional models, it positions readiness as an emergent property of stakeholder interaction, negotiation, and coalition-building-offering novel insights within the BPM domain. Our findings contribute a theory-driven, politically grounded ERP readiness model that offers both diagnostic insight and prescriptive guidance for ERP leaders.

    Exploring the key enablers of robotic process automation in the maritime industry
    (Palgrave Macmillan Ltd, 2025) Karakas, Serkan
    The term autonomy in the maritime industry has become increasingly popular thanks to the availability of new technologies, such as artificial intelligence, advanced IoT sensors, and satellite communication systems. However, the widespread adoption of fully autonomous ships requires overcoming serious technological, legal, and social challenges. Implementing robotic process automation (RPA), or software robots, represents a cost-effective and minimally invasive solution and allows automating processes without significant modifications to existing IT infrastructure. However, theoretical research on the enablers of RPA remains limited, particularly concerning its application in commercial vessels. To address this gap, this study adopts the Technology-Organisation-Environment (TOE) framework and employs the fuzzy DEMATEL methodology to identify the critical factors that facilitate the adoption of shipboard RPA. Empirical insights are derived from the involvement of nine highly qualified experts. The findings show that software robots can possess the capability to enhance shipboard processes, providing a viable solution at a time when the widespread use of full automation remains infeasible. Furthermore, our findings provide important insights for policymakers regarding the way software robots can improve the shipboard ecosystem, onboard quality standards, and regulatory compliance with maritime practices. This research contributes by examining both the theoretical and practical dimensions of robotic process automation in shipboard applications-an area that, as said, has received limited scholarly attention.

    Introducing a managerial decision-support tool for technology adoption in supply chains: a case study in the shipbuilding industry
    (Taylor & Francis Ltd, 2025) Karakas, Serkan; Acar, Avni Zafer
    Blockchain technology promises significant benefits within the scope of the supply chain and attracts the attention of scholars and practitioners. Academic research focused on revealing the disruptive potential of blockchain in supply chains, in functional and structural dynamics, is visibly increasing. Furthermore, businesses have realised the potential of the technology, and several have launched various platforms, such as CargoX, Blockshipping, and IQAX's eBL. Some platforms, however, have ceased to exist due to a number of challenges, including costs, low profitability, and scalability-related issues. This context highlights the need for a holistic and practical perspective on the net value of blockchain adoption that considers both the benefits and risks of the technology. Nevertheless, the primary shortcoming of the existing research is that the proposed adoption models are mostly conceptual and have low applicability. Therefore, this study aims to fill this gap by introducing the net value of adopting technology. The proposed methodology outlines the computational foundation of the proposed net value metric, and an engineering firm operating in the shipbuilding supply chain is identified for pilot application and early implementation of the proposed decision-support model.

    Maritime sustainability: Navigating complex challenges and ecological footprints
    (Springer, 2024) Karakas, Serkan; Acar, A. Zafer; Kirmizi, Mehmet
    The maritime industry holds significant importance in facilitating international trade and contributing to the overall well-being of societies. Maritime activities encompass significant ecological and social results, in addition to their economic value. For instance, carbon emissions from maritime transportation remain a significant challenge, necessitating the implementation of various strategies and technologies to mitigate the issue. Nevertheless, the concept of maritime sustainability encompasses various complex aspects that have significant social and environmental implications. There are ongoing conflicts concerning the sharing of ocean resources among various maritime stakeholders. One additional concern pertains to the environmental inequality that exists between high-income and low-income countries in terms of ship recycling and demolition. Herewith, this chapter considers the various facets of sustainability in the maritime industry, including a recent term of blue economy, where sustainable economics intertwines with ecological well-being. Extensive discussion is also provided on contemporary technological and systems approaches aimed at mitigating the detrimental environmental effects of maritime operations. By interweaving ethnoeconomics and the welfare of coastal communities, this chapter also provides an in-depth discussion on recent issues such as ethical consumerism of maritime resources and environmental injustice. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

    Women in maritime career: Are they still discriminated?
    (Elsevier Ltd, 2026) Arslan, Aykut; Sahinoglu, Özgür Sivan; Karakas, Serkan; Kirmizi, Mehmet
    This research embarks on a journey to explore three antecedents of career theory: career regret, career aspirations, and work meaningfulness, and their intricate relationship with gender discrimination in a male-dominated workplace, specifically the maritime industry. This study is firmly rooted in self-determination theory, which posits that three innate psychological needs–competence, autonomy, and relatedness–guide individuals to grow and change. This study focuses on the career pendulum of women seafarers, a critical area that aims to draw attention to and assist career scholars and practitioners in comprehending, predicting, and facilitating a broader context of career literature's subjective outcomes through the lens of women employees in a male-dominated workplace. A conceptual model is unveiled, incorporating the negative aspects of career theory, namely gender discrimination and career regret. Both of these significantly and negatively affect job meaningfulness, and career regret has a mediation role in gender discrimination and job meaningfulness; at the same time, career aspirations moderate the relationship between career regret and job meaningfulness. © 2026 Elsevier Ltd.
