A model that,scheduling a set,of stochastic jods on a single machine that is subject to breakdorwn and repair is dicussed.The model assumes that a significant set-up time,which is an arbitrary variable,is when the machine changes from processing one of jobs to another job.When job i is being processed, the prooessing time of job i,uptime and reparied time of the machine are all general random variables. For both preemptive resume model and preemptive repeat model,we find the optimal polices that minimize the following objective functions:(1)the weighted sum of the completion times;(2)the weighted number of late jobs having random dud dates with exponential distributions.
