In this paper, the stochastic scheduling problem of minimizing the total weighted completion time on preemptive identical parallel machines is investigated. Each job has a processing time, which is a random variable and just given their distribution function. First, we extend the stochastic single-machine preemptive WSEPT rule to a multi-machine list scheduling policy, which we call P-WSEPT. T hen, we use LP based policy to analysis the performance guarantee of preemptive stochastic scheduling with release dates.
