  1. 1. Contributions within two topics in integer programming : nurse scheduling and column generation

    Författare :Elina Rönnberg; Torbjörn Larsson; Marco Lübbecke; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Integer programming can be used to provide solutions to complex decision and planning problems occurring in a wide variety of situations. The application of integer programming to solve real world problems requires a modelling phase in which the problem at hand is translated into a mathematical description of the problem, and a solution phase that aims at developing methods for producing solutions to the mathematical formulation of the problem.

  3. 2. Methods and Applications in Integer Programming : All-Integer Column Generation and Nurse Scheduling

    Författare :Elina Rönnberg; Torbjörn Larsson; Fredrik Altenstedt; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; integer programming; column generation; set partitioning problems; quasi-integrality; nurse scheduling; Optimization; systems theory; Optimeringslära; systemteori;

    Sammanfattning : Integer programming can be used to provide solutionsto complex decision and planning problems occurring in a wide varietyof situations. Applying integer programming to a real life problembasically involves a first phase where a mathematical model isconstructed, and a second phase where the problem described by themodel is solved.

  4. 3. Optimization of Snow Removal in Cities

    Författare :Roghayeh Hajizadeh; Kaj Holmberg; Elina Rönnberg; Henrik Andersson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Removing snow in a city is an unavoidable task in Nordic countries like Sweden. A number of streets in an area need to be cleared of snow by a limited number of vehicles and the tours for the vehicles must be planned in order to minimize the time and/or cost. LÄS MER

  5. 4. Optimisation-based scheduling of an avionic system

    Författare :Emil Karlsson; Elina Rönnberg; Kaj Holmberg; Simin Nadjm-Tehrani; Anders Nordby Gullhav; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Modern computer systems in aircraft are often 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

  7. 5. 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;
