Waiting time approximation in single-class queueing systems with multiple types of interruptions: modeling congestion at waterways entrances
2009,
We consider a single-server queue subject to multiple types of operation-independent interruptions...
Single-machine scheduling with both deterioration and learning effects
2009,
This paper considers a single-machine scheduling problem with both deterioration and learning effects. The...
Assignment problems with changeover cost
