1. 1. Simulation Modelling of a Shift to Service-Based Offerings : Resource efficiency and operational implications in the context of the circular economy

   Författare :Raphael Wasserbaur; Tomohiko Sakao; Erik Sundin; Steve Evans; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resource efficiency; resource effectiveness; circular economy CE ; sociotechnical systems; systems thinking; simulation; product service system PSS ; system dynamics;

   Sammanfattning : 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.

3. 2. Handling severe uncertainty in strategic project appraisal : Methods and applications of context analysis

   Författare :Anton Talantsev; Aron Larsson; David Sundgren; John Ward; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Decision Intelligence; Deep Uncertainty; Scenario Analysis; Multiple Criteria Decision Analysis; Simulation; Context Analysis; Project Appraisal; Risk Assessment; Threat and Opportunity; Computer and Systems Sciences; data- och systemvetenskap;

   Sammanfattning : The long-term success or failure of a strategic project is largely shaped by its context. Therefore, the assessment of the external factors influencing the fulfilment of project long-term goals is vital for the effective project appraisal and planning. LÄS MER

4. 3. Enhancing IT Systems Cyber Resilience through Threat Modeling : Cyber Security Analysis of Enterprise Systems and Connected Vehicles

   Författare :Wenjun Xiong; Robert Lagerström; Simon Hacks; Jelena Zdravkovic; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cyber Security; Threat Modeling; Attack Simulations; IT Systems; Security Analysis; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Information technology (IT) systems are growing in complexity and are becoming more and more connected. Such connected systems can increase flexibility and productivity while also introducing security threats. LÄS MER

5. 4. On Statistical Methods for Safety Validation of Automated Vehicles

   Författare :Daniel Åsljung; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; performance evaluation; extreme value theory; Automotive; validation; automated vehicles; simulation; verification; automated driving systems;

   Sammanfattning : Automated vehicles (AVs) are expected to bring safer and more convenient transport in the future. Consequently, before introducing AVs at scale to the general public, the required levels of safety should be shown with evidence. However, statistical evidence generated by brute force testing using safety drivers in real traffic does not scale well. LÄS MER

7. 5. Driver behavior models for evaluating automotive active safety: From neural dynamics to vehicle dynamics

   Författare :Gustav M Markkula; Chalmers tekniska högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; simulation; active safety; control behavior; system evaluation; Driver models;

   Sammanfattning : The main topic of this thesis is how to realistically model driver behavior in computer simulations of safety critical traffic events, an increasingly important tool for evaluating automotive active safety systems. By means of a comprehensive literature review, it was found that current driver models are generally poorly validated on relevant near-crash behavior data. LÄS MER
