   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Circular economy; circular manufacturing systems; resource conservative manufacturing; ResCoM; system dynamics; Production Engineering; Industriell produktion;

   Sammanfattning : The society today lives on the philosophy of ‘take-make-use-dispose.’ In the long run, this is not sustainable as the natural resources and the waste carrying capacity of the earth are limited. Therefore, it is essential to reduce dependency on the natural resources by decoupling the growth from the consumption. LÄS MER

5. 4. Model-Based Investigation of Machining Systems Characteristics : Static and Dynamic Stability Analysis

   Författare :Andreas Archenti; Mihai Nicolescu; Amir Rashid; KTH; []
   Nyckelord :Machining systems; modelling; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : The increasing demands for precision and efficiency in machining call for new control strategies for machining systems based on the identification of static and dynamic characteristics under operational conditions. By considering the machining system as a closed-loop system consisting of a machine tool structure and a machining process, the join system characteristics can be analyzed. LÄS MER

7. 5. Automotive Remanufacturing in a Changing Market : Challenges and Opportunities in a market with a growing share of electric cars

   Författare :Robert Casper; Erik Sundin; Mats Björkman; Amir Rashid; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Circular Economy; Remanufacturing Process Challenges and Improvements; Process Efficiency; Automotive Part Remanufacturing and Reuse; Internal Combustion Engines ICE ; Battery Electric Vehicles BEV ; Cirkulär Ekonomi; Återtillverkning; Återtillverkningsprocesser; Processeffektivitet; Bilindustri; Förbränningsmotorer; Elbilar; Elektrifiering;

   Sammanfattning : This doctoral thesis deals with closed-loop supply chains, which include remanufacturing. Remanufacturing can be described as an industrial process to bring back a used good into an “as-good-as-new” condition. Furthermore, focus is put on one of the largest global industry sectors: the automotive industry. LÄS MER
