    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; mathematical optimization; flexible job shop scheduling; mixed integer linear programming MILP ; complexity analysis; mathematical modelling; production planning; multi-purpose machine; dispatching rule; priority function; total flowtime; total tardiness; release date; due date; due date;

    Sammanfattning : Volvo Aero has invested in a complex production cell containing a set of multipurpose machines. The problem of finding optimal schedules for this multitask cell is a complex combinatorial optimization problem which is recognized as a flexible job shop problem. This thesis proposes an approach to find such schedules using mathematical optimization. LÄS MER
