  1. 21. Mathematical Optimization in Flexible Job Shop Scheduling: Modelling, Analysis, and Case Studies

    Författare :Karin Thörnblad; Göteborgs universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Flexible job shop scheduling; Mixed integer linear programming MILP ; Time-indexed formulation; Makespan; Tardiness; Fixture availability; Preventive maintenance; Night shift; Unmanned time window; Dynamic scheduling; Priority rules; Dispatching rules; Critical ratio; Night shift;

    Sammanfattning : The major theme of this thesis is the mathematical optimization modelling of the flexible job shop scheduling problem. This problem is present in the so-called multitask cell—a production cell at GKN Aerospace's facility located in Trollhättan, Sweden—which has served as a case study during the work with this thesis.

  3. 22. Enabling Timing Analysis of Complex Embedded Software Systems

    Författare :Johan Kraft; Christer Norström; Anders Wall; Ian Broster; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Embedded-systems; Real-time-systems; Timing-analysis; Simulation; Simulation-optimization; Simulation-Model-Extraction; Source-code-analysis; Run-time-monitoring; Model-validation; Computer science; Datavetenskap; Computer Science; datavetenskap;

    Sammanfattning : Cars, trains, trucks, telecom networks and industrial robots are examples of products relying on complex embedded software systems, running on embedded computers. Such systems may consist of millions of lines of program code developed by hundreds of engineers over many years, often decades. LÄS MER

  4. 23. Adaptive Hierarchical Scheduling Framework for Real-Time Systems

    Författare :Nima Khalilzad; Thomas Nolte; Martina Maggio; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; datavetenskap;

    Sammanfattning : Modern computer systems are often designed to play a multipurpose role. Therefore, they are capable of running a number of software tasks (software programs) simultaneously in parallel. These software tasks should share the processor such that all of them run and finish their computations as expected. LÄS MER

  5. 24. Resource Optimization in Multi-processor Real-time Systems

    Författare :Hamid Reza Faragardi; Thomas Nolte; Johan Tordsson; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis addresses the topic of resource efficiency in multiprocessor systems in the presence of timing constraints.  Nowadays, almost wherever you look, you find a computing system. Most computing systems employ a multiprocessor platform. LÄS MER

  7. 25. Performance and Optimization Aspects of Time Critical Networking

    Författare :Emmanouil Fountoulakis; Nikolaos Pappas; Vangelis Angelakis; Qi Liao; Ness B. Shroff; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : 5G and beyond networks are driven by the vision of the Internet of Things and mission-critical communications that have time-sensitive applications requiring low latency. These new, related to the previous network generations, requirements are challenging and they have a technical impact on the design of communication networks and classical networks cannot support such requirements.
