Mine scheduling requires input variables such as geological model and economic values in order to deliver an optimal production schedule. Geological uncertai...

The classical maximum closure problem is of particular importance to the mining industry because it is the underlying formulation related to mine design and ...

This paper attempts to incorporate equipment selection/allocation into the optimization of open pit mine production scheduling. Equipment selection has been ...

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...

The spatial continuity of lithology and ore grade is one of the key factor for proper mine planning. Traditional geostatistical methods are used for spatial ...

In the era of big data, data sets have been growing very large, and interest for algorithms and computation framework that handle such large scales is increa...

This paper proposes a heuristic approach based on network flow techniques to schedule the production in open-pit mines, while accounting for metal uncertaint...

Tropical algebra is the study of algebraic structures (tropical maps, idempotent semimodules, etc), constructed over the semifield `(\underline{\mathbb{R}} ...

In the literature, the study of price subsidies of new technologies has focused on the tactical problem of achieving maximum penetration under a budget con...

Traditionally, mining engineers plan an open pit mine considering pre-stablished conditions of operation of the plant(s) derived from a previous plant optimi...

We design and implement a dynamic program (DP) for valuing corporate securities, seen as derivatives on a firm's assets, and computing the term structure o...

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...

Mining operations can be modelled as a supply chain from the sources of raw material (mines) through various processing streams to the final saleable product...

Preferential sampling of high grade zones is a common practice in the drilling campaigns of ore deposits. This may lead to a bias in the statistics derived f...

Unconditional consensus is the property of a consensus algorithm for multiple agents, to produce consensus irrespective of the particular time or state at wh...

This paper presents an analysis of Canadian energy and climate policies in terms of the coherence between federal and provincial/territorial strategies. Afte...

Parkinson's disease (PD) is a multifactorial disease known to result from a variety of factors. Although age is the principal risk factor, other etiological ...

In this paper we present a comparative study of several strategies that can be applied to achieve the so-called elementary lower bound in vehicle routing p...

In this paper we propose the use of twin graphs for optical transport network (OTN) physical topology design. Some properties inherent to twin graphs are fa...
