Abstract [en]

It is estimated that the adaptation of the Circular Economy approach can yield material cost savings of hundreds of billions of dollars per year for the EU and can result in huge environmental benefits. To tap this potential, the manufacturing industry needs to take a circular approach, where the products are designed intentionally to be used for multiple lifecycles. However, there is a lack of methodologies to date that can support such an approach. To fill this gap, this research has proposed a novel methodological approach that can support designing products for multiple lifecycles to keep the products as well as the components and the materials at their highest utility and value at all times. This research has identified that there is a strong synergy among the concepts of product design strategies, product obsolescence and product end-of-life options. Taking this synergy as the foundation and adopting modular architectures in the product design and development process, lifecycle planning can be performed for products that will sustain multiple lifecycles. This research is performed in two steps: first, the research review process is used to explore the knowledge base in the field of product design methodologies and based on the insights from the literature a novel methodological approach is proposed; second, a case example is used to demonstrate the applicability and effectiveness of the proposed methodological approach.

Abstract [en]

A transition towards circular manufacturing systems (CMS) has brought awareness of untapped economic and environmental benefits for the manufacturing industry. Despite this increased interest, the implementation of CMS is still in its infancy stage. To support the manufacturing industry in implementing CMS in practice, this research seeks to (1) explore the main characteristics of CMS and their needs for a successful implementation in the context of the manufacturing industry, and (2) develop quantitative analysis tools to support decision-making in implementing CMS with a concurrent focus on economic and environmental performance. By viewing CMS as complex adaptive systems (CAS), this research proposes to exploit complex system modelling and simulation used in the study of CAS to characterise, model, and analyse CMS. In this regard, a multi-method simulation model architecture that combines features of agent-based, discrete-event, and system dynamics modelling methods is proposed to model and simulate CMS as different abstraction levels are needed to capture the complex and dynamic interactions among the elements of the system. The resulting multi-method simulation tool aims at providing systemic quantification of CMS in terms of economic performance (e.g., lifecycle costs, lifecycle revenues, and lifecycle profits), environmental performance (e.g., lifecycle environmental impact), and technical performance (e.g., quality, quantity and timing of product return flows), and therefore, facilitates decision-making for industrial organizations implementing CMS in practice.

Abstract [sv]

En övergång till cirkulära tillverkningssystem (CMS) har skapat medvetenhet om outnyttjade ekonomiska och miljörelaterade fördelar för tillverkningsindustrin. Trots det ökade intresset är implementeringen av CMS fortfarande i sin linda. För att stödja tillverkningsindustrin med att implementera CMS i praktiken, strävar denna forskning efter att (1) utforska de viktigaste egenskaperna hos CMS och de behov som finns för att en framgångsrik implementering av CMS i tillverkningsindustrin ska kunna ske, och (2) utveckla kvantitativa analysverktyg som kan användas som beslutstöd vid implementering av CMS med samtidigt fokus på ekonomisk och miljömässig prestanda. Genom att behandla CMS som komplexa adaptiva system (CAS), föreslår denna forskning att utnyttja komplex systemmodellering och simulering som används i CAS för att karaktärisera, modellera och analysera CMS. I detta avseende föreslås en arkitektur för multimetodisk simuleringsmodell som kombinerar egenskaper från agentbaserade, diskret händelsestyrda, och systemdynamiska modelleringsmetoder för att modellera och simulera CMS. Denna kombination är nödvändig för att fånga de komplexa och ömsesidiga interaktionerna mellan delarna i systemet. Den resulterande multi-metodiska simuleringsmodellen syftar till att ge insikter om hur CMS beter sig i termer av ekonomi (t.ex. livscykelkostnader, livscykelintäkter och livscykelvinster), miljömässighet (t.ex. miljöpåverkan under livscykeln) och teknisk prestanda (t.ex. kvalitet, kvantitet och tidpunkt för produktreturflöden) och därigenom underlättar beslutsfattande för industriella organisationer som vill implementerar CMS.
