“…But each machine can only perform one operation at a time, and whenever a machine is shifted from one operation to another, a setup operation is needed. They showed that the makespan minimization problem can be reduced to three subproblems: (i) zero-setup prob- Ham et al (1985) Simple sort C max (GT, Optimal) Baker (1990) Simple sort C max (GT, Optimal) Logendran and Sriskandarajah (1993) Constructive C max (GT) (block, zbfr) Cetinkaya and Kayaligil (1992) Simple sort C max (Unit transfer batch, Optimal) Vickson and Alfredsson (1992) Simple sort C max (unit transfer batch, Optimal) Lee and Mirchandani (1988) Constructive C max (Versatile machines, Approximate) Cheng and Wang (1999a) Dynamic Programming C max (Versatile machines, one setup, Optimal) Ching, Liao, and Wu (1997) Constructive C max (Two part types, bottleneck machine, Approximate) Cheng and Kovalyov (1998) Dynamic Programming C max (Two part types, bottleneck machine, Optimal) Cheng and Wang (1998) Multi-sort C max (one machine batch processor, special caes, Optimal) Cheng, Lin, and Toker (2000) Multi-sort C max (Batch processors special cases, Optimal) Cheng and Wang (1999b) Multi-sort C max (fabrication, assembly special cases, Optimal) Chen, Potts, and Strusevich (1998) Simple sort C max (batch splitting, Approximate) Zdrzalka (1995) Simple sort C max (batch splitting, Approximate) Baker (1995) Simple sort C max (Lot streaming, Optimal) Cetinkaya (1994) Multi-sort C max (Lot streaming, Optimal) Vickson (1995) Multi-sort, ILP C max (Lot streaming, Optimal) Bukchin, Tzur, and Jaffe (1999) Constructive ¥C i (single job heuristic) Li (1997) Constructive C max (multiple machines at stage 2, Approximate) Kim, Kang and Constructive C max (Hybrid flowshop) 3 Steiner (1997, 1998) Computation C max (Lot streaming, single job, Optimal) m Hitomi and Ham (1976) Branch & Bound C max (GT, Optimal) Ham, Hitomi, and Yoshida (1985) Branch & Bound C max (GT, Optimal) Ham, Hitomi, and Yoshida (1985) Multi-sort C max (GT, Approximate) Vakharia and Chang (1990) Simulated Annealing C max (GT, Approximate) Skorin- Kapov and Vakharia (1993) Tabu Search C max (GT, Approximate) Sridhar and Rajendra (1994) Genetic algorithm C max (GT, Approximate) …”
