Network Design Foundation Fall 2011 Graph Balancing : A special case of scheduling on unrelated machines

چکیده
Here, we consider approximation algorithms for the Graph Balancing problem which is a special case of the job scheduling on unrelated parallel machines to minimize the makespan. We present an interpretation of the 2approximation LP-rounding algorithm given by Lenstra et al. to the special case of graph balancing. We then show how the approximation guarantee can be improved by the technique of adding additional valid constraints to the linear program.

On the Configuration-LP for Scheduling on Unrelated Machines
One of the most important open problems in machine scheduling is the problem of scheduling a set of jobs on unrelated machines to minimize the makespan. The best known approximation algorithm for this problem guarantees an approximation factor of 2. It is known to be NP -hard to approximate with a better ratio than 3/2. Closing this gap has been open for over 20 years. The best known approximat...
متن کاملFlexible flowshop scheduling with equal number of unrelated parallel machines
This article addresses a multi-stage flowshop scheduling problem with equal number of unrelated parallel machines. The objective is to minimize the makespan for a given set of jobs in the system. This problem class is NP-hard in the strong sense, so a hybrid heuristic method for sequencing and then allocating operations of jobs to machines is developed. A number of test problems are randomly ge...

متن کاملA comparison of algorithms for minimizing the sum of earliness and tardiness in hybrid flow-shop scheduling problem with unrelated parallel machines and sequence-dependent setup times
In this paper, the flow-shop scheduling problem with unrelated parallel machines at each stage as well as sequence-dependent setup times under minimization of the sum of earliness and tardiness are studied. The processing times, setup times and due-dates are known in advance. To solve the problem, we introduce a hybrid memetic algorithm as well as a particle swarm optimization algorithm combine...
