Quantifying operational uncertainties in mining machinery fleet productivity using a stochastic Overall Equipment Effectiveness (OEE) analysis

Key Points

• Operational uncertainties significantly affect the overall equipment effectiveness of mining machinery.
• The stochastic analysis revealed that uncertainties can lower productivity metrics by up to 20% under certain conditions.
• Analysis utilizing overall equipment effectiveness metrics addresses multiple sources of variability in machinery performance.
• These findings underscore the need for precise quantification of operational uncertainties to improve mining efficiency.
