This file contains dataset of four small-sized problems, P9, P12, P16, and P24; three large-sized problems, P65, P148 and P205. P9, P12, and P24 are taken from Kim et al. (2000). P16 and P65 and P205 are taken from Lee et al. (2001), and P148 is taken from Bartholdi (1993). The precedence diagrams and the preferred directions of tasks are taken from the literature directly.<br>The operation time of task i by robot r is randomly generated between [ 0.8xt, 1.2xt], where t is the original published operation time in the Özcan and Toklu (2009) and Delice et al. (2014). For every problem three levels of setup time variability are set: · No setup time. · The matrix of setup times is randomly generated based on uniform distribution U[0,0.25* ] for <i>low variability.</i> · The matrix of setup times is randomly generated based on uniform distribution U[0,0.75* ] for <i>high variability.</i>
