“…There were some attempts in the past to develop exact algorithms to minimise the maximum lateness considering mostly single machines, and sometimes two-machines and m-machines (e.g., Smith, 1956;Townsend, 1977;Grabowski, 1980). There exist some exact methods to solve the two-machine and m-machine permutation flowshops with two objectives (e.g., Selen and Hott, 1986;Wilson, 1989;Daniels and Chambers, 1990;Rajendran, 1992;Ulungu and Teghem, 1995;Sivrikaya-Serifoglu and Ulusoy, 1998;Cheng and Shakhlevich, 1999;Sayin and Karabati, 1999;Lemesre et al, 2007; also see T'Kindt and Billaut (2002), for a comprehensive treatment of multi-objective scheduling, in general). It appears that the multi-objective flowshop scheduling problems have not been explored much, and exact approaches to solve multi-objective optimisation problems in scheduling are quite uncommon.…”
