  2. 21. Optimization heuristic solutions, how good can they be? : With empirical applications in location problems

    Author : Xiangli Meng; Kenneth Carling; Christoph Flath; Högskolan Dalarna; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

    Abstract : Combinatorial optimization problems, are one of the most important types of problems in operational research. Heuristic and metaheuristics algorithms are widely applied to find a good solution. READ MORE

  4. 22. Planning and Provisioning Strategies for Optical Core Networks

    Author : Ajmal Muhammad; Robert Forchheimer; Lena Wosinska; Massimo Tornatore; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Optical communication networks are considered the main catalyst for the transformation of communication technology, and serve as the backbone of today's Internet. The inclusion of exciting technologies, such as, optical amplifiers, wavelength division multiplexing (WDM), and reconfigurable optical add/drop multiplexers (ROADM) in optical networks have made the cost of information transmission around the world negligible.

    Author : Lars Backåker; Lundgren Jan; Johanna Törnquist Krasemann; Stefan Engevall; Markus Bohlin; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Rail freight planning; trip plan generation; routing and scheduling; dynamic assignment;

    Abstract : Rail freight transportation is recognized worldwide as a suitable transportation mode when it comes to long haul transportation of heavy commodities. The industry is also known to be capital intensive, highly dependent on infrastructural developments and requires thorough planning of operations. READ MORE

  6. 24. The role of fault management in the embedded system design

    Author : Carlo Vitucci; Daniel Sundmark; Thomas Nolte; Fredrik Asplund; Mälardalens universitet; []

    Abstract : In the last decade, the world of telecommunications has seen the value ofservices definitively affirmed and the loss of the connectivity value. This changeof pace in the use of the network (and available hardware resources) has ledto continuous, unlimited growth in data traffic, increased incomes for serviceproviders, and a constant erosion of operators’ incomes for voice and ShortMessage Service (SMS) traffic.

  7. 25. Flexibility in Statically Scheduled Real-Time Systems

    Author : Gerhard Fohler; Mälardalens högskola; []
    Keywords : ;

    Abstract : Static scheduling has been shown to be appropriate for a variety of hard real-time systems, mainly due to the verifiable timing behavior of the system and the complex task models supported. Its application is, however, impeded in systems with changing operational modes and critical activities, that arrive infrequently with unknown occurrence times. READ MORE
