  5. 14. Optimisation methods for solving a large-scale avionics scheduling problem

    Författare :Emil Karlsson; Elina Rönnberg; Kaj Holmberg; Simin Nadjm-Tehrani; Musliu Nysret; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optimisation; Decomposition; Large-scale scheduling; Avionics scheduling;

    Sammanfattning : Modern computer systems in aircraft are based on an integrated modular avionic architecture. In this architecture, software applications share hardware resources on a common avionic platform. Many functions in an aircraft are controlled by software and a failure in such software can have severe consequences. LÄS MER
