On the Evaluation of Non-Preemptive Strategies in Stochastic Scheduling

  • K. D. Glazebrook
Part of the NATO Advanced Study Institutes Series book series (ASIC, volume 84)


A collection of stochastic jobs is to be processed by a single machine. The jobs must be processed in a manner which is consistent with a precedence relation but the machine is free to switch from one job to another at any time. Such switches are costly, however. A general model is proposed for this problem. Sufficient conditions are given which ensure that there is an optimal strategy given by a fixed permutation of the job set. These conditions are then used as a starting point for the important task of evaluating permutations as strategies in more general circumstances where no permutation is optimal.
