Operational Operations Research at the Mathematical Centre

Article Abstract:

Consulting in operations research at the Mathematical Centre in Amsterdam is reviewed. The activities of the Department of Operations Research and System Theories are highlighted, as are three practical projects of the Mathematical Centre (MC). MC was founded in 1946, as a non-profit institution promoting mathematics in the areas of pure mathematics, applied and numerical mathematics, mathematical statistics, operations research, system theory and computer science. It is backed by the government through the Netherlands Organization for the Advancement of Pure Research. It also engages in public and private consulting activities. The 1980 budget was funded by the government for eighty-five per cent. About one hundred and fifty persons are employed by MC. Current research projects focus on combinatorial optimization, analysis and control of information flow, and system and control theory. A public transportation problem is featured.

Preemptive scheduling in a two-stage multiprocessor flow shop is NP-hard

Article Abstract:

Preemptive scheduling in a two-stage flow shop with at least two identical parallel machines in one of the stages to minimize makespan is NP-hard in the strong sense. Johnson's efficient algorithm presented in 1954 for minimizing makespan in two-machine flow shop cannot be used for preemptive scheduling. McNaughton's wrap-around rule presented in 1959 calculates the shortest preemptive schedule on identical parallel machines in linear time but there is no similarly effective algorithm for the simplest common generalization of the problem.
