摘要
The properties of two-machine no-wait flow-shop scheduling problem, with a non-resumable unavailable interval are studied. This research discusses two cases: a non-resumable unavailable interval in the first and second machines respectively. The problems’ complexities are proved to be NP-hard. The Gilmore and Gomory Algorithm (GGA) is applied to minimize the makespan, and the conditions that GGA yields the optimal solutions are presented. Sixty numerical examples with ten-job and two-machine are generated to test the proposed theorems. Compared to the results obtained by the Johnson algorithm, the GGA algorithm yields an 8.15% improvement on average. Moreover, the worst-case performance ratios of GGA are proved to be 2. © 2017 Chinese Institute of Industrial Engineers.
