A best possible on-line algorithm for two-machine flow shop scheduling to minimize makespan

We address a two-machine flow shop on-line scheduling problem. Jobs arrive over time. Each job becomes available for processing at its release time after which it must be processed without preemption on the first machine and then on the second machine. The objective is to minimize the makespan. We p...

Zusammenfassung:We address a two-machine flow shop on-line scheduling problem. Jobs arrive over time. Each job becomes available for processing at its release time after which it must be processed without preemption on the first machine and then on the second machine. The objective is to minimize the makespan. We provide a best possible deterministic on-line algorithm with a competitive ratio of (5+1)/2. Computational experiments on randomly generated problem instances are performed and the results show that the online algorithm is very useful to obtain near-optimal solutions.
