On polynomial solvability of two multiprocessor scheduling problems

We discuss a new approach for solving multiprocessor scheduling problems by using and improving results for guillotine pallet loading problem. We introduce a new class of schedules by analogy with the guillotine restriction for cutting stock problem and show that many well-known algorithms from classical scheduling theory construct schedules only from this class. We also consider two multiprocessor scheduling problems and prove that they can be solved in polynomial time. Copyright Springer-Verlag Berlin Heidelberg 1999
