Abstract: This paper proposes a two-level PSO algorithm for open-shop scheduling problem. In this algorithm, the upper-level PSO algorithm fine-tunes the parameter values for the lower-level PSO algorithm; the lower-level PSO algorithm then uses the given parameter values to generate the solutions for open-shop scheduling problem. The proposed two-level PSO-based algorithm performs very well on the benchmark instances.
