Abstract

In the paper we consider strongly NP-hard flow shop problem with the criterion of minimization of the sum of job's finishing times. We present the parallel algorithm based on the scatter search method. Obtained results are compared to the best known from the literature. Superlinear speedup has been observed in the parallel calculations.
