5 Uncertainty in conventional closed-loop In the conventional closed-loop manufacturing the reverse supply chains are the most uncertain part of the business Uncertainty in: Return quantity Return timing Return quality 5

6 Uncertainty in conventional closed-loop Our research concluded that: Business models are not developed for closing the loop Products are not designed to cater the needs of closed-loop strategies Supply chains are not supportive to closed-loop flows Technology- lifecycle management tools are not capable of supporting closed-loop products 6

7 Circular Manufcaturing System Recycling Remanufacturing Reuse Product design Value proposition Material extraction Material processing Manufacturing Use Source: Lieder M, 2017 forward and REVERSE flows Virtual flows: Information Physical flows: components, products, materials. 7

8 Circular Manufcaturing System Circular manufacturing system is a system that is designed intentionally for closing the loop of products/components and materials preferably in their original or enhanced form, through multiple lifecycles. This is a value management approach which includes the phases of value creation, delivery, use, recovery and reuse in a systemic perspective. 8

12 Systemic approach Dynamic interactions and causal relationships Efficient and effective management using ICT Product design Value model ICT Supply chain 12

13 ResCoM developments Facilitating industrial implementation of the circular manufacturing systems. An innovative and practical framework Supported by a lifecycle management software platform The framework offers a system design methodology based on simultaneous consideration to business model, design and supply chains with their dynamic interactions included The software platform offers multiple lifecycle information analysis and management for collaboration, transparency and efficiency 13
