The viability of novel network-level circular business models (CBMs) is debated heavily. Many companies are hesitant to implement CBMs in their daily practice, because of the various roles, stakes and opinions and the resulting uncertainties. Testing novel CBMs prior to implementation is needed. Some scholars have used digital simulation models to test elements of business models, but this this has not yet been done systematically for CBMs. To address this knowledge gap, this paper presents a systematic iterative method to explore and improve CBMs prior to actual implementation by means of agent-based modelling and simulation. An agent-based model (ABM) was co-created with case study participants in three Industrial Symbiosis networks. The ABM was used to simulate and explore the viability effects of two CBMs in different scenarios. The simulation results show which CBM in combination with which scenario led to the highest network survival rate and highest value captured. In addition, we were able to explore the influence of design options and establish a design that is correlated to the highest CBM viability. Based on these findings, concrete proposals were made to further improve the CBM design, from company level to network level. This study thus contributes to the development of systematic CBM experimentation methods. The novel approach provided in this work shows that agent-based modelling and simulation is a powerful method to study and improve circular business models prior to implementation.
Business model innovations emerge over time and are influenced by managerial interaction with stakeholders. Especially with regard to business model innovation for sustainability, manager-stakeholder interaction can radically change a company’s business model and underlying logic. However, the majority of the literature shows how manager–stakeholder interaction may limit business model innovation when stakeholders reinforce existing managerial cognitions. In this chapter we study how stakeholders can also stimulate business model innovation by affecting managerial cognitive change. Through three case studies, we find that this can occur through three shaping processes: market approach shaping, product/service offering shaping, and credibility shaping. We also find that the impact of new or latent stakeholders is greater than that of existing stakeholders. We end the chapter by sketching a research agenda to further unravel the role of stakeholders affecting managerial cognition around business model innovation for sustainability.
An important issue in the field of motion control of wheeled mobile robots is that the design of most controllers is based only on the robot’s kinematics. However, when high-speed movements and/or heavy load transportation are required, it becomes essential to consider the robot dynamics as well. The control signals generated by most dynamic controllers reported in the literature are torques or voltages for the robot motors, while commercial robots usually accept velocity commands. In this context, we present a velocity-based dynamic model for differential drive mobile robots that also includes the dynamics of the robot actuators. Such model has linear and angular velocities as inputs and has been included in Peter Corke’s Robotics Toolbox for MATLAB, therefore it can be easily integrated into simulation systems that have been built for the unicycle kinematics. We demonstrate that the proposed dynamic model has useful mathematical properties. We also present an application of such model on the design of an adaptive dynamic controller and the stability analysis of the complete system, while applying the proposed model properties. Finally, we show some simulation and experimental results and discuss the advantages and limitations of the proposed model.
Het doel van dit interdisciplinaire SIA KIEM project Fluïde Eigenschap in de Creatieve Industrie is te onderzoeken of en hoe gedeelde vormen van eigenaarschap in de creatieve industrie kunnen bijdragen aan het creëren van een democratischer en duurzamer economie, waarin ook het MKB kan participeren in digitale innovatie. Het project geeft een overzicht van beschikbare vormen van (gedeeld) eigenaarschap, hun werking en hoe deze creatieve professionals kunnen ondersteunen bij de transitie naar de platformeconomie. Dit wordt toegepast op een concrete case, dat van een digitale breimachine. Naast het leveren van een goede praktijk, moet het project leiden tot een groter internationaal onderzoeksvoorstel over Fluid Ownership in the Creative Industry, dat dieper ingaat op de beschikbare eigendomsoplossingen en hoe deze waarde zullen creëren voor de creatieve professional.
The textile industry contributes over 8% of global greenhouse gas emissions and 20% of the world's wastewater, exceeding emissions from international flights and shipping combined. In the European Union, textile purchases in 2020 resulted in about 270 kg of CO₂ emissions per person, yet only 1% of used clothes are recycled into new garments.To address these challenges, the Textile Hub Groningen (THG) aims to assist small and medium-sized enterprises (SMEs) and stakeholders in forming circular textile value chains, hence reducing waste. Designing circular value chains is complex due to conflicting interests, lack of shared understanding, knowledge gaps regarding circular design principles and emerging technologies, and inadequate tools for collaborative business model development. The potential key stakeholders in the circular textile value chain find it hard to use existing tools and methods for designing these value chains as they are often abstract, not designed to be used in a collaborative setting that fosters collective sense making, immersive learning and experimentation. Consequently, the idea of circular textile value chain remains abstract and hard to realize.Serious games have been used in the past to learn about, simulate and experiment with complex adaptive systems. In this project we aim to answer the following research:How can serious games be leveraged to design circular textile value chains in the region?The expected outcomes of this project are: • Serious game: Facilitates the design of circular textile value chains• Academic Publication: Publish findings to contribute to scholarly discourse.• Future Funding Preparation: Mobilize partners and prepare proposals for follow-up funding to expand the approach to other domains.By leveraging game-based collaborative circular value chain and business model design experiences, this project aims to overcome barriers in designing viable circular value chains in the textile industry.
The textile industry is responsible for over 8% of global greenhouse gas emissions and 20% of the world’s wastewater, surpassing the emissions from international flights and shipping combined. In the European Union, textile purchases in 2020 led to around 270 kg of CO₂ emissions per person, yet only 1% of used clothing is recycled into new garments. The municipality of Groningen manages an estimated 950 kilotons of textile waste but is only able to collect, sort, and recycle 250 kilotons. To address these challenges, Textile Hub Groningen (THG) seeks to support small and medium-sized enterprises (SMEs) and stakeholders in creating circular textile value chains. However, designing circular value chains presents challenges, including conflicting interests, knowledge gaps on circular design principles, and inadequate tools for collaborative business model development. Potential stakeholders often find current tools too abstract and not conducive to collaboration, learning, or experimentation. As a result, circular value chains remain difficult to achieve from the perspective of individual stakeholders. Serious games have been employed to simulate and experiment with complex adaptive systems , . Research shows that well-designed playful learning enhances both learning and motivation, particularly when social elements are integrated . This project aims to answer the following research question: How can serious games be leveraged to design circular textile value chains in the region? The expected outcomes are: 1. Serious Game: Design, test, and deliver a serious game to facilitate the joint design of circular textile value chains. 2. Publications: Extract insights from the game’s design and evaluation, contributing to both academic and practical discussions. 3. Consortium for Follow-up: Mobilize partners and secure funding for future projects in related fields. Through game-based collaborative circular value chain and business model design experiences, this project overcomes barriers in designing viable circular value chains in the textile industry
