Title: | Scheduling parallel machines with inclusive processing set restrictions and job release times | Authors: | Li, CL Wang, X |
Issue Date: | 1-Feb-2010 | Source: | European journal of operational research, 1 Feb. 2010, v. 200, no. 3, p. 702-710 | Abstract: | We consider the problem of scheduling a set of jobs with different release times on parallel machines so as to minimize the makespan of the schedule. The machines have the same processing speed, but each job is compatible with only a subset of those machines. The machines can be linearly ordered such that a higher-indexed machine can process all those jobs that a lower-indexed machine can process. We present an efficient algorithm for this problem with a worst-case performance ratio of 2. We also develop a polynomial time approximation scheme (PTAS) for the problem, as well as a fully polynomial time approximation scheme (FPTAS) for the case in which the number of machines is fixed. | Keywords: | Scheduling Parallel machines Release times Worst-case analysis Polynomial time approximation scheme |
