Research paper: Triple-Use Innovation: Embedding Sustainability into Civil-Military Innovation
The provided academic paper introduces and develops the concept of triple-use innovation, which systematically expands the traditional dual-use paradigm (civilian and military applications) to fundamentally embed sustainability as a third, co-equal dimension. This new framework advocates for an integrated innovation process where technological development is aligned with planetary boundaries and focused on enhancing systemic resilience against converging climate and security crises. By drawing upon concepts like Responsible Research and Innovation (RRI) and resilience thinking, the authors propose a structured approach for co-designing civil, defense, and sustainability goals from the inception stages of invention through incubation and final implementation. Ultimately, the paper establishes the theoretical foundation for a model that moves beyond fragmented policy to ensure that innovation strengthens both security and environmental viability under conditions of global uncertainty.

Research paper: AI-Powered Value Co-Creation: A Case Study Approach to Smart PSS Development
The academic paper "AI-Powered Value Co-creation: A Case Study Approach to Smart PSS Development" explores the strategic adoption and impact of Artificial Intelligence (AI) on value co-creation within Product-Service Systems (PSS) across various industrial sectors. The authors argue that while the technical implementation of AI in PSS is often prioritized, the strategic rationale for its use and its influence on collaborative value creation are often overlooked. Using a multiple case study approach across fields like healthcare and industrial systems engineering, the research identifies three key benefits of AI: fostering stakeholder collaboration, uncovering novel value propositions, and building dynamic knowledge ecosystems. The paper organizes its findings by distinguishing between AI's role in co-production (design stages) and value-in-use (operational stages) of a PSS, ultimately concluding that AI acts as a powerful catalyst for transforming data into actionable insights and enabling resource integration.

Research paper: Leveraging digital twins for value-driven design in smart product-service systems: the super-system digital twin framework and SEV case study
Recent academic contributions explore the integration of Digital Twins (DTs) within smart Product-Service System (sPSS). This integration aims to innovate business propositions, hardware and services. However, gaps persist in developing DT environments to support early-stage collaborative innovation for sPSS, and limited studies explore how real-time synchronized digital replicas enhance value co-creation in this area. This paper addresses this gap by presenting a framework and practical example of integrating value-driven decision support into early sPSS conceptual design. A case study on the development of the Smart Electric Vehicle (SEV) conducted with a global automotive Original Equipment Manufacturer (OEM) demonstrates the framework’s efficacy. Through qualitative data analyses based on experimental validation in a case company, the DT proves effective in aiding decision makers in selecting value-adding configurations within specific scenarios. Furthermore, the DT serves as a visual decision-making tool, fostering collaboration across diverse teams within the automotive company. This collaboration facilitates value creation across practitioners with varied backgrounds, emphasizing the DT’s role in enhancing early-stage innovation and co-creation processes in the sPSS domain.

Research paper: Designing value-robust circular systems through changeability: a framework with case studies
Increasing sustainability expectations requires support for the design of systems that are reactive in minimizing potential negative impact and proactive in guiding engineering decision-making toward more value-robust long-term decisions. This article identifies a gap in the methodological support for the design of circular systems, building on the hypothesis that computer-based simulation models will drive the development of more value-robust systems designed to behave positively in a changeable operational environment during the whole lifecycle. The article presents a framework for value-robust circular systems design, complementing the current approaches for circular design aimed at increasing decision-makers' awareness about the complexity of circular systems to be designed. The framework is theoretically described and demonstrated through its applications in four case studies in the field of construction machinery investigating new circular solutions for the future of mining, quarrying and road construction. The framework supports the development of more resilient and sustainable systems, strengthening the feedback loop between exploring new technologies, proposing innovative concepts and evaluating system performance.

The transport sector accounts for a significant share of the world’s greenhouse gas emissions, and the project’s goal is to reduce these by improving resilience, energy efficiency and environmental impact, and optimizing a marine transport system. Waterborne public transport has great potential to reduce congestion and increase capacity in cities, especially by utilizing waterways in combination with road and rail transport networks.The project has investigated different solutions for a marine transport system, with a particular focus on energy efficiency, charging, energy storage and infrastructure. A central goal has been to develop a model to optimize a system that can withstand disruptions in energy supply. Through simulations, the system’s dimensioning, battery storage and use of fuel cells have been evaluated to improve both resilience and operational reliability.The results show that it is possible to develop a more resilient and flexible transport system by combining electrification, land-based battery storage and fuel cells on board ships. This system has the potential to reduce climate impact, improve accessibility and increase transport efficiency, especially in cities. The simulations indicate that the system can reduce both energy and time consumption in urban traffic. To further develop the system, future tests and optimization using AI for real-time operation are planned, as well as tests of the system in Karlskrona. In addition, the possibility of implementing a dual-use use of the system is being investigated, which would make it possible to use the ferries for other purposes, such as evacuating civilians and animals or transporting supplies and injured people.
