A note to: A multiple-rule based constructive randomized search algorithm for solving assembly line worker assignment and balancing problem.

Some of the solutions reported in a recent paper (Akyol and Baykasoglu in J Intell Manuf 30(2):557–573, 2019. https://doi.org/10.1007/s10845-016-1262-6) are infeasible, jeopardising the conclusion that "best results for the 75% of the 320 test instances for the ALWABP-2" were obtained. In this note, we explore the contributions of the paper, show that some of the solutions are indeed infeasible and point out possible inconsistencies in the employed heuristic that may be causing this issue.
