“…Based on a common platform, a configure-to-order strategy enables to quick response to varying customer mission requirements. Similar to Rehn et al (2018), they find that reconfigurability through modularity can be of significant value under uncertain lifetime circumstances, such as changing ship missions or requirements. When designing flexible systems, agility, as a parameter denoting the ease of change, needs to be determined.…”

“…De Neufville and Scholtes (2019) give a comprehensive overview on flexibility in engineering design and suitable methods. Rehn et al (2018) find that changeability/flexibility can be a suitable strategy to respond to time-affected uncertainties and is hence worthwhile discussing in the early design phase. Within an extensive report, Schank et al (2016) provide a naval perspective on flexibility and modularity.…”

Marine systems design methodology is continuously evolving. On a strategic level, we have seen four major evolutionary tracks emerging from the sequential, iterative process captured in the classical design spiral. One is a model-based systems engineering approach that removes iterations by a structured mapping from needs to functions, and further to form elements that are finally synthesized into a complete design. Another is a set-based strategy, where a large number of designs are generated and analysed, from which one or a few solutions are selected for further development. A third direction is a holistic optimization strategy where the major steps in the spiral model are integrated onto a common platform that enables the automatic identification of one or a few balanced, preferable solutions. Finally, as a strategy towards improved competitiveness through standardization in a typical engineered-to-order industry, we have seen the emergence of modular architectures combined with configuration-based design methods. Across these four evolutionary tracks there have been several more focused developments on different levels of maturity. This includes design-for-sustainability, simulation of operations, design-for-flexibility to handle uncertainty and change, and design of wind-assisted vessels. Finally, we have pointed to some emerging developments that we find promising but have yet to mature into having a significant impact on industry level applications. This includes artificial intelligence and machine learning, extended system boundaries, and digital twin technologies.

“…Such a perspective distinguishes changeability from other ilities, such as reliability or resilience, where the requirements are constant, and efforts are geared toward absorbing the effects of the changing contexts (Saleh, Mark & Jordan 2009; Mekdeci et al 2015). Similarly, changeability differs from versatility, where the system is designed primarily to satisfy changing requirements (de Weck et al 2012; Rehn et al 2018). This distinction is illustrated in Figure 1, where the focus of this review on changeability is highlighted in blue.…”

The ongoing servitization journey of the manufacturing industries instills a through-life perspective of value, where a combination of products and services is delivered to meet expectations. Often described as a product-service system (PSS), these systems are poised with many complexity aspects, introducing uncertainties during the design phase. Incorporating changeability is one of the known strategies to deal with such uncertainties, where the system changes in the face of uncertainty to sustain value, thereby achieving value robustness. While the theme of dealing with multiple uncertainties has been discussed since the inception of PSS, changeability is still poorly addressed. To bridge this gap, an integrative literature review is performed to outline various complexities aspects and their link to uncertainty from a PSS perspective. Also, the state-of-the-art approach to achieving value robustness is presented via changeability incorporation. Subsequently, a reference framework is proposed to guide decision-makers in changeability incorporation in PSS, especially during the early design stages.

“…Another approach is to accept the uncertainty and develop strategies that can handle uncertainties, including adaptive control, use of margins, resilience, robust design, optimization under uncertainty, Markov Decision Process (MDP), and fuzzy decision support (Garcia Agis, 2020). Ship design concepts of flexibility/changeability, modularity, and robustness have been studied extensively and demonstrated to be effective under uncertain lifetime conditions (Rehn et al, 2018;Choi et al, 2018;Schank et al, 2016). describe the introduction of agility as a parameter for fuel-flexible ships, including preparing vessels to be converted later in life.…”

The maritime industry faces a critical challenge to decarbonize and meet the ambitious goal of net-zero emissions by 2050. This transition requires innovative ship design strategies to address the increasing complexity and multiplicity of technical solutions amidst dynamic regulatory, geopolitical, and market uncertainties. This paper examines the maritime decarbonization challenge's impact on ship design and decision-making under uncertainty, highlighting the necessity for collaboration between researchers and practitioners to tackle this emerging challenge. To navigate the uncertainty, stakeholders can integrate advanced design methods and decision-making processes considering the full lifecycle and fleet-level implications. This paper promotes taking a holistic approach that incorporates regulatory compliance, technological advancements, and commercial considerations, as well as a blend of methods to manage decision-making under uncertainty. Continued research in specific areas is essential to develop and refine frameworks that optimize design and operation for the industry's sustainable future.
