Unbounded parallel batch scheduling with job delivery to minimize makespan
We consider unbounded parallel batch scheduling with job delivery to minimize makespan. When the jobs have identical size, we provide a polynomial-time algorithm. When the jobs have non-identical sizes, we provide a heuristic with a worst-case performance ratio 7/4. c © 2008 Published by Elsevier B.V.
متن کاملSingle Machine Scheduling with Job Delivery to minimize makespan
In the single machine scheduling problem with job delivery to minimize makespan, jobs are processed on a single machine and delivered by a capacitated vehicle to their respective customers. We first consider the special case with a single customer, that is, all jobs have the same transportation time. Chang and Lee (2004) proved that this case is strongly NP-hard. They also provided a heuristic ...
متن کاملScheduling jobs with release dates and tails on two unrelated parallel machines to minimize the makespan
In this paper we deal with the problem of assigning a set of n jobs, with release dates and tails, to either one of two unrelated parallel machines and scheduling each machine so that the makespan is minimized. This problem will be denoted by R2jri; qijCmax. The model generalizes the problem on one machine 1jri; qijCmax, for which a very ecient algorithm exists. In this paper we describe a Bra...
متن کاملScheduling two interfering job sets on uniform parallel machines with makespan and cost functions
We consider a m uniform parallel machines scheduling problem with two jobs A and B with nA and nB operations, respectively, and equal processing times. Job A is associated with a general cost function F, whereas makespan is considered for job B. As we are dealing with two conflicting criteria, we focus on the calculation of strict Pareto optima for F and C max criteria. We also tackle some part...
متن کاملScheduling parallel jobs to minimize the makespan
We consider the NP-hard problem of scheduling parallel jobs with release dates on identical parallel machines to minimize the makespan. A parallel job requires simultaneously a prespecified, job-dependent number of machines when being processed. We prove that the makespan of any nonpreemptive list-schedule is within a factor of 2 of the optimal preemptive makespan. This gives the best-known app...
