    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

  3. 2. Phenolic compounds and ascorbic acid in black currant (Ribes nigrum L.) : variation due to genotype, ontogenetic stage, harvest date and location
