The characterization of the spatial continuity of categorical variables, such as geological units, is a longstanding subject in geostatistics. Indicator cova...

This paper proposes a stochastic integer programming (SIP) formulation to address the optimization of long-term mine production schedules, whereby the supply...

Cutoff grade specifies the available supply of metallic ore from an open pit mine for the multiple processing and refining streams of the corresponding minin...

BibTeX reference
