📐 Key Calculations

Demurrage Exposure Reduction

ΔT × Rate
Result: $1.2M/month saved
Direct cost avoidance from reduced idle time

Stockpile Overflow Probability

P(Q_in > Q_out + Capacity)
Result: Reduced from 38% to 7%
Mitigated environmental spill risk

📊 Results

22% reduction in average train turnaround time; $14.6M annual OpEx savings; zero stockpile overflows in 18 months

💡 Lessons Learned

  • •Telematics integration must include GPS, load sensors, and engine diagnostics
  • •Berth scheduling requires 48-hr lookahead window with weather contingency
