Abstract. The N-NEH+ algorithm is one of the most efficient construction algorithms for solving the permutation flow-shop problem with the makespan criterion. It extends the well-known NEH heuristic with the N-list technique. In this paper, we propose the Starting Point (SP) method that employs a new strategy for using the N-list technique. Extensive numerical experiments on the standard set of Taillard's and VRF benchmarks show that the SP method significantly improves the results of the N-NEH+ algorithm.
