The unsustainable levels of resource use and emissions of our economies and their threat to future generations are core issues of our time. The circular economy (CE) conceptualises a different type of economy that is restorative and regenerative by design and aims to keep products, components and materials at their highest utility and value at all times, distinguishing between technical and biological cycles. The novelty of the CE requires the development of new analytical tools and methods as well as ways of thinking to understand its consequences. This research summarises four years of research on the topic of systems analysis and simulation modelling in the domain of the CE. Three topics were of major interest: First, what are the resource efficiency implications of a shift toward a CE? Second, what are the operational implications of a shift to a CE? And finally, how can systemic changes towards a CE be understood and planned? Four studies were conducted addressing the three research questions. The first study applies material flow analysis to a washing machine manufacturer case and looks at how different business models affect the resource flows of critical resources. It finds that service-based offerings lead to higher overall resource efficiency. The second study focuses on the implications of CE initiatives on the maintenance activities of a heat-as-a-service provider. It shows that the shift to service-based offerings requires service providers to face worse-before-better situations where long-term benefits offset short-term disadvantages. The third study is a simulation-based case study of laundry practices in Sweden. It compares a sharing economy scenario where a population shares washing machines with a scenario where the majority of people own the washing machines they are using. The results indicate that in Sweden and Europe in general, sharing has significant resource savings potential in the domestic laundry sector. The fourth study is a conceptualisation of design fixation to higher levels of analysis. It identifies examples of fixations on the organisational and institutional level. In addition, it argues that in order to design sustainable sociotechnical systems, aspects like governmental policies and business models need to be considered design parameters. A shift to a CE needs to happen on many levels of society. This research presents simulation models that can support corporate and political decision makers in the shift to a CE. It shows that in order to understand the CE, the analysis has to be, on the one hand, able to simulate system dynamics, and on the other hand connect the multiple levels of society. De ohållbara nivåerna av resursutnyttjande och utsläpp av våra ekonomier och deras hot mot framtida generationer är en av dagens nyckelutmaningar. Cirkulär ekonomi (CE) är en konceptualisering av en ny typ av ekonomi som är baserad på återställande och regenerativ design, som siktar på att behålla nyttan och värdet så högt som möjligt i produkter, komponenter och material, indelad i deras teknologiska och biologiska cykler. Nymodigheten av CE erfordrar utvecklingen av nya analytiska verktyg och metoder så väl som annorlunda sätt att tänka för att förstå dess konsekvenser. Den här rapporten summerar fyra år av forskning på ämnet systemanalys och simulationsmodellering i domänen av CE. Tre ämnen var av högt intresse. Vilka är de miljömässiga konsekvenserna av ett skifte till CE? Vilka är de operationella konsekvenserna av ett skifte till CE? Hur kan den systematiska förändringen till en CE bli planerad och förstådd? Vi utförde fyra studier för att undersöka de tre frågorna. Första artikeln använder materialflödesanalys i en fallstudie på en tvättmaskinstillverkare, och undersöker hur olika affärsmodeller påverkar flödet av kritiska resurser. Den visar att erbjudande baserade på service leder till en högre övergripande resurseffektivitet. Den andra artikeln fokuserar på implikationerna av CE initiativ på underhållsaktiviteter för en värme-som-tjänst-distributör. Den visar att skiftet till en CE kräver att möta sämre-innan-bättre-situationer där långsiktiga fördelar kompenserar för kortsiktiga nackdelar. Tredje artikeln är en simulationsbaserad fallstudie på tvättvanor i Sverige. Det jämför ett delningsekonomiscenario där en population delar tvättmaskiner mot ett scenario där majoriteten av population är ägare av egna tvättmaskiner. Resultaten indikerar att det finns en signifikant besparingspotential av resurser både i Sverige och i Europa generellt. Fjärde artikeln är en konceptualisering av design fixation till högre analytiska nivåer. Den identifierar exempel på fixation på en organisationell och en institutionell nivå. Utöver det så argumenteras det att i design av hållbara sociotekniska system aspekter som myndighetspolicyers och affärsmodeller behöver vara designparameter. CE är ett koncept som finns i många nivåer av samhället från produktdesign till myndighetspolicyers. Det här forskning presenterar simulationsmodeller som kan stödja affärsmässiga och politiska beslutsfattare inom skiftet till en CE. Denna uppsats visar att för att förstå CE, så måste analysen dels kunna simulera systemdynamik, samt dels koppla till de multipla nivåerna i samhället. Der hohe Ressourcenverbrauch und das hohe Emissionsniveau, die mit der westlichen Lebensweise einhergehen sind ein Hauptproblem unserer Zeit. Die Kreislaufwirtschaft (zu englisch „circular economy“) ist ein alternatives Wirtschaftsmodel, das darauf abzielt, den Wert von Produkten, Komponenten und Materialien über deren Lebenszeit zu erhalten. Die relative Neuheit dieses Wirtschaftsmodels erfordert es, neue analytische Methoden, Werkzeuge und Denkweisen zu entwickeln. Diese Doktorarbeit umfasst vier Jahre Forschung an den Themen Systemanalyse und Simulationsmodellierung im Bereich der Kreislaufwirtschaft. Drei Fragen standen im Zentrum: Erstens, welche Auswirkungen hat ein Wechsel zur Kreislaufwirtschaft auf die Ressourceneffizienz? Zweitens, welche Auswirkungen hat ein Wechsel von produzierenden Unternehmen zur Kreislaufwirtschaft auf deren Betriebsführung? Drittens, wie können die notwendigen systemischen Veränderungen verstanden und geplant werden. Diese Dissertation basiert auf vier Studien, die unterschiedliche Aspekte eines gesellschaftlichen Wandels zur Kreislaufwirtschaft beleuchten. Die erste Studie ist eine Materialflussanalyse, die die Ressourceneffizienz unterschiedlicher Geschäftsmodelle eines Waschmaschinenherstellers vergleicht. Dabei stellt sich heraus, dass servicebasierte Angebote zu einer erhöhten Ressourceneffizienz führen können. Die zweite Studie untersucht die Auswirkungen einer Umstellung auf Heat-as-a-Service-Angebote aus der Sicht eines Heizgeräteherstellers und dessen Betriebsführung. Die Studie zeigt, dass der Hersteller in Situation gerät, in der kurzfristige erhöhte Kosten mit langfristigen Prozessverbesserungen und geringeren Instandhaltungskosten abgewogen werden müssen. Als drittes wird eine Simulationsstudie präsentiert, in der die Wäschepraxis in Schweden im Fokus steht. Mehrere Szenarien werden verglichen, in denen die Bevölkerung dazu übergeht, Gemeinschaftswaschküchen anstatt eigener Haushaltwaschmaschinen zu verwenden. Die Simulationsergebnisse zeigen, dass, falls umgesetzt in großen Teilen der Bevölkerung, diese Sharing Economy-Praxis ein großes Potential zur Einsparung von Ressourcen hat. In der vierten Studie wird das Konzept der „design fixation“ als mögliche Ursache für die Trägheit unserer gesellschaftlichen Systeme festgemacht. Design fixation als Phänomen beschreibt das Festhalten eines Designers an bestehenden Ideen und Konzepten, das das Endergebnis des Designprozesses einschränkt. Diese vierte Studie liefert eine Einschätzung des Einflusses von design fixation auf den Ressourcenverbrauch in sociotechnischen Systemen. Eine Umstellung zur Kreislaufwirtschaft bedeutet ein Wandel auf mehreren Ebenen der Gesellschaft. Die Komplexität dieses alternativen Wirtschaftsmodells, erfordert die Verwendung adäquater Modelle, die in der Lage sind, Gesellschaftsebenen kausal zu verknüpfen, und die entsprechenden Systemdynamiken zu simulieren. In dieser Doktorarbeit werden mehrere Simulationsmodelle präsentiert, die für Entscheidungsträger in Politik und Industrie nützlich sind, um die Kreislaufwirtschaft in ihrem Milieu besser verstehen zu können.

Commissioned by the Society for Modeling and Simulation International (SCS), this needed, useful new ‘Body of Knowledge’ (BoK) collects and organizes the common understanding of a wide collection of professionals and professional associations. Modeling and simulation (M&S) is a ubiquitous discipline that lays the computational foundation for real and virtual experimentation, clearly stating boundaries—and interactions—of systems, data, and representations. The field is well known, too, for its training support via simulations and simulators. Indeed, with computers increasingly influencing the activities of today’s world, M&S is the third pillar of scientific understanding, taking its place along with theory building and empirical observation. This valuable new handbook provides intellectual support for all disciplines in analysis, design and optimization. It contributes increasingly to the growing number of computational disciplines, addressing the broad variety of contributing as well as supported disciplines and application domains. Further, each of its sections provide numerous references for further information. Highly comprehensive, the BoK represents many viewpoints and facets, captured under such topics as: Mathematical and Systems Theory Foundations Simulation Formalisms and Paradigms Synergies with Systems Engineering and Artificial Intelligence Multidisciplinary Challenges Ethics and Philosophy Historical Perspectives Examining theoretical as well as practical challenges, this unique volume addresses the many facets of M&S for scholars, students, and practitioners. As such, it affords readers from all science, engineering, and arts disciplines a comprehensive and concise representation of concepts, terms, and activities needed to explain the M&S discipline. Tuncer Ören is Professor Emeritus at the University of Ottawa. Bernard Zeigler is Professor Emeritus at the University of Arizona. Andreas Tolk is Chief Scientist at The MITRE Corporation. All three editors are long-time members and Fellows of the Society for Modeling and Simulation International. Under the leadership of three SCS Fellows, Dr. Ören, University of Ottawa, Dr. Zeigler, The University of Arizona, and Dr. Tolk, The MITRE Corporation, more than 50 international scholars from 15 countries provided insights and experience to compile this initial M&S Body of Knowledge.

The growing mobility needs of travellers have led to the development of increasingly complex and integrated multi-modal transit networks. Hence, transport agencies and transit operators are now more urgently required to assist in the challenging task of effectively and efficiently planning, managing, and governing transit networks. A pre-condition for the development of an effective intelligent multi-modal transit system is the integration of information and communication technology (ICT) tools that will support the needs of transit operators and travellers. To achieve this, reliable real-time simulation and short-term forecasting of passenger demand and service network conditions are required to provide both real-time traveller information and successfully synchronise transit service planning and operations control. Modelling Intelligent Multi-Modal Transit Systems introduces the current trends in this newly emerging area. Recent developments in information technology and telematics have enabled a large amount of data to become available, thus further attracting transport researchers to set up new models outside the context of the traditional data-driven approach. The alternative demand-supply interaction or network assignment modelling approach has improved greatly in recent years and has a crucial role to play in this new context.

Industrial Product-Service Systems (IPS2), which is defined as “an integrated industrial product and service offering that delivers value in use,” has expanded rapidly over the last decade. IPS2 has allowed us to achieve both high added value and high productivity and has enriched our QOL by improving the performance of products and services. We are now struggling with many awkward issues related to sustainability, but IPS2 is expected to be the “philosopher’s stone” for solving these issues. Following the pattern of conferences held in Cranfield in 2009, Linköping in 2010, and Braunschweig in 2011, the fourth International CIRP Conference on Industrial Product-Service Systems, held on November 8-9, 2012, in Tokyo, will cover various aspects of IPS2. Topics planned for this year’s conference reflect the latest IPS2 information in both the natural sciences and humanities and include case studies from various industries. IPS2 is still a relatively new field, so it is important to keep track of the entire context in order to promote more cross-sectional cooperation between multimodal fields and disciplines. The fourth International CIRP Conference on Industrial Product-Service Systems will serve as a vital platform for such collaborations and the discussion of new scientific ideas.
