Production Scheduling Nahmias, Chapter 8 ( D t lj l i ) (sv ...

Conclusions Regarding Scheduling
• Scheduling is hard!
– Even simple toy problems generate complicated mathematics.
• Scheduling can be simplified by adjusting the production
environment:
– due date quoting
– flow simplification ⇒ sequencing in place of scheduling
• Finite capacity scheduling is coming.
– But in what form is unclear (shifting bottleneck, genetic
algorithms, rule based systems, etc.).
• Diagnostics are important in scheduling. scheduling
– pure optimization generally impossible
– need good interface to allow human intervention
