Traditional mining selection methods focus on local estimates or loss functions that do not take into account the potential diversification benefits of financial risk that is unique to each location. A constrained efficient set model with a downside risk function is formulated as a solution. Estimates of this nonlinear mixed-integer combinatorial optimization problem are provided by a simulated annealing heuristic. A utility framework that is congruent with the proposed efficiency model is then… 
Financially Efficient Dig-Line Delineation Incorporating Equipment Constraints and Grade Uncertainty
Greedy local search heuristics that provide estimates of financially efficient dig-lines are proposed. To generate alternate dig-lines these heuristics employ a floating circle-based perturbation
An Iterative Construction Heuristic for the Ore Selection Problem
An innovative neighbourhood search heuristic is proposed for the ore selection problem that employs a stochastic demolition and reconstruction strategy and produces better quality solutions faster than a relay hybrid (constructive-simulated annealing) heuristic.
Grade control based on economic ore/waste classification functions and stochastic simulations: examples, comparisons and applications
Abstract Grade control and ore/waste delineation in open pit mining operations was traditionally based on the comparison of estimated grades with an economic cutoff. In the 1990s, an alternative
Planning an Iron Ore Mine: From Exploration Data to Informed Mining Decisions
Introduction Background Australia managed to avoid many of the effects of the 2008 Global Financial Crisis, thanks largely to a booming mining economy invigorated by China's unprecedented increase in
Internal Performance Evaluation: the Case of Bank Branches
This paper proposes a new approach for gauging the performance of branch managers of a financial institution by defining a Measure of Internal Performance (MIP). Our proposal is different from others
Reduced Basis Kriging for Big Spatial Fields
This work develops an alteration to this method by utilizing the approximations made in fixed rank kriging combined with restricted maximum likelihood estimation and sparse matrix methodology, which is applied to climate data archived by the United States National Climate Data Center with very good results.
Using simulated maps to interpret the geochemistry, formation and quality of the Blue Gem coal bed, Kentucky, USA
Abstract This study presents geostatistical simulations of coal-quality parameters, major oxides and trace metals for an area covering roughly 812 km 2 of the Blue Gem coal bed in southeastern
False discovery rates for large-scale model checking under certain dependence
ABSTRACT In many scientific fields, it is interesting and important to determine whether an observed data stream comes from a prespecified model or not, particularly when the number of data streams
A hierarchical model for characterising spatial wafer variations
Silicon wafers are commonly used materials in the semiconductor manufacturing industry. Their geometric quality directly affects the production cost and yield. Therefore, improvement in the quality
Transport analysis of ozone enhancement in Southern Ontario during BAQS-Met
Abstract. Twice-daily ozonesondes were launched from Harrow, in southwestern Ontario, Canada, during the BAQS-Met (Border Air Quality and Meteorology Study) field campaign in June and July of 2007. A


Optimal ore selection decisions under uncertainty are currently considered in terms of the expected utility, which involves post-processing conditional probability distributions of grade values using
An Expected Gain-Confidence Limit Criterion for Portfolio Selection
A new efficiency criterion is proposed for the Markowitz portfolio selection approach. It is shown that the use of standard deviation as a measure of risk in the original Markowitz analysis and

A model which takes into account characteristics of the portfolio optimization problem which are disregarded in most optimization models, which generalizes one of the linear models which recently appeared in the literature as an alternative to the classical Markowitz model is presented.
Heuristics for cardinality constrained portfolio optimisation
This paper extends the standard mean-variance portfolio optimisation model to include cardinality constraints that limit a portfolio to have a specified number of assets, and to impose limits on the proportion of the portfolio held in a given asset.

So it is equal to the group of portfolio will be sure. See dealing with the standard deviations. See dealing with terminal wealth investment universe. Investors are rational and return at the point.
Applying modern portfolio theory to upstream investment decision making
Nobel laureate Harry Markowitz provided investors with a framework to optimize risk and return of their portfolios of stocks and bonds. With a small portfolio of upstream investments as an example,
Models of Capital Budgeting, E-V VS E-S
Markowitz's [2] portfolio selection model was originally concerned with financial investments, but the model's implications for capital budgeting are now well recognized. Markowitz's basic idea is

Applying Financial Portfolio Theory to Product Portfolio Decisions: An Empirical Study
To date no formal studies of applying financial portfolio theory to product portfolio decisions have appeared in the literature. This article describes an empirical study to explore the feasibility
