Parallel machine scheduling with minimum number of tardy jobs: Approximation and exponential algorithms

作者:

Highlights:

• Minimizing the number of tardy jobs on parallel machines cannot be approximated in polynomial time.

• Sub-exponential time approximation algorithms are proposed for both the unweighted and weighted case.

• When the number of machines is fixed, the problem of minimizing the number of tardy jobs on identical parallel machines is fixed parameter tractable.
