Purpose: The purpose of this paper is twofold: an approach is proposed to determine the optimum replacement time for shovel teeth; and a risk-quantification approached is developed to derive a confidence interval for replacement time. Design/methodology/approach: The risk-quantification...

Extreme events, characterized as infrequent and catastrophic occurrences, can present significant challenges in various industries. These events can be associated with earthquakes, landslides, hurricanes, floods, rainfalls, and wildfires. The mining industry is also highly vulnerable to extreme...

Purpose – The purpose of this paper is to provide a decision-making tool on where to send mining parcels extracted in such a way as to minimize losses arising from mis-classification. The problem is complicated because actual values of mining parcels cannot be known and the decision is made on...
