Abstract

AbstractIn this paper we consider the single machine scheduling problem with one non-availability interval to minimize the maximum lateness where jobs have positive tails. Two cases are considered. In the first one, the non-availability interval is due to the machine maintenance. In the second case, the non-availability interval is related to the operator who is organizing the execution of jobs on the machine. The contribution of this paper consists in an improved FPTAS for the maintenance non-availability interval case and the elaboration of the first FPTAS for the operator non-availability interval case. The two FPTAS are strongly polynomial.KeywordsSchedulingNon-availability constraintLatenessFPTAS
