There is an everlasting distance and interdependence between mines and end-users as it
involves different types of equipment, infrastructure, and facilities, including excavators …

Existing methods of pushback (phase) design are reviewed in the context of “gap” problems,
a term used to describe inconsistent sizes between successive pushbacks. Such gap …

Similar to the mixed-integer programming library (MIPLIB), we present a library of publicly
available test problem instances for three classical types of open pit mining problems: the …

A hyper-heuristic refers to a search method or a learning mechanism for selecting or
generating heuristics to solve computational search problems. Operating at a level of …

Given a discretized representation of an ore body known as a block model, the open pit
mining production scheduling problem that we consider consists of defining which blocks to …

Production scheduling is a critical activity for the long-term production planning of open pit
mining operations. It deals with the effective management of resources and maximizes cash …

In order to establish a production plan, an open-pit mine is partitioned into a three-
dimensional array of blocks. The order in which blocks are extracted and processed has a …

Environmental responsibility and the sustainable development of mineral resources are a
topic of critical importance to the mining industry and at the same time relate to operational …

Scheduling production in open-pit mines is characterized by uncertainty about the metal
content of the orebody (the reserve) and leads to a complex large-scale mixed-integer …

A recursive time aggregation-disaggregation (RAD) heuristic is proposed to solve large-
scale multidimensional and multiperiod precedence-constrained knapsack problems …
