We present a novel method to determine the optimal transition timing in mining.
- class="label">•
Our model is detailed enough so as to be applicable to mine planning.
- class="label">•
Our solution methodology exploits recent developments in the production scheduling literature.
- class="label">•
These developments enable us to solve very large problem instances very quickly.
