Abstract : The Circular Economy (CE) is perceived as one of the main instruments to achieve sustainable development goals (SDGs). Even though companies are showing increasing interest to transform their businesses into a circular economy model, they are experiencing difficulties due to a lack of methods, tools, and indicators to assess circularity strategies and to measure the performance of reverse logistics systems. There are limited studies on the assessment of CE strategies of a product, supply chain, and service at the micro-level. The main objective of this Ph.D. thesis is to propose methods and tools to evaluate circularity strategies and measure the performance of reverse logistics. The study begins with identifying decision-making factors and indicators. Afterward, modeling of the reverse logistics system is accomplished to understand the complex interaction among decision variables. Then a circular economy assessment method, tool, and indicators have been developed to assist companies in the decision-making process. A case study with multiple companies is performed to examine, validate and demonstrate the applicability of the proposed model, tools and indicators. The main contributions of this Ph.D. thesis include: * a taxonomy of decision-making variables and circular economy indicators for reverse logistics, * a system dynamics model to represent the complex system of reverse logistics system in order to understand the complex interaction among end-of-life decision variables, * a circular economy indicator for reverse logistics that used to measure the performance of products in reverse logistics system, * a circular economy assessment method to evaluate the potential environmental and economic benefits of transforming a firm into a circular business, * a circular economy assessment tool to evaluate circularity strategies of end-of-life products, and * a systematic analysis of the interplay among diverse disciplines including reverse supply chain, business model; product and service design; product and service use; policy and end-of-life (EoL) treatment in circular economy research. The findings of this PhD work assist industrial practitioners in decision-making on the management of post-used products. The contributions of this Ph.D. thesis deemed to support the transition towards a more sustainable circular economy.
