1. 1. Towards Model-Based Development of Self-Managing Automotive Systems : Modeling, Simulation, Model Transformations and Algorithms: Supporting the Development of the DySCAS Middleware

   Författare :Tahir Naseer Qureshi; Martin Törngren; DeJiu Chen; Ivica Crnkovic; KTH; []
   Nyckelord :Dynamic Reconfiguration; DySCAS; Self-Managing Systems; Load Balancing; Quality of Service QoS ; Model-Based Development; Modeling; Simulation; Model Transformation; Middleware; Embedded Systems; Component Based Design; Unified Modeling Language UML™ ; Discrete Event Systems; Real-Time Systems; Software Architecture; Simulink®; SimEvents™; Distributed Systems.;

   Sammanfattning : With the increased usage of electronics, embedded computer systems, software and networks in modern vehicles, the complexity is also increasing in terms of the development process, functionalities as well as their implementation. On one hand there is a need for efficient and systematic development, and on the other hand the systems are required to have enhanced post-deployment time configuration management support. LÄS MER

3. 2. Model-driven Alignment : Linking Business Strategy with Information Systems

   Författare :Constantinos Giannoulis; Jelena Zdravkovic; John Krogstie; Stockholms universitet; []

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Automotive; Embedded systems; Architecture; Dependability; Cost; Systems engineering; Systemteknik;

   Sammanfattning : Dealing properly with electronics and software will be a strong competitive advantage in the automotive sector in the near future. Electronics are driving current innovations and are at the same time becoming a larger part of the cost of the vehicle. LÄS MER

5. 4. Aircraft Systems Modeling : Model Based Systems Engineering in Avionics Design and Aircraft Simulation

   Författare :Henric Andersson; Petter Krus; Olof Johansson; Fredrik Berglund; Linköpings universitet; []
   Nyckelord :MBSE; MBD; Avionics; Simulation; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Aircraft developers like other development and manufacturing companies, are experiencing increasing complexity in their products and growing competition in the global market. One way to confront the challenges is to make the development process more efficient and to shorten time to market for new products/variants by using design and development methods based on models.
