Metal price is one of the most important parameters in the calculation of cut- off grade. The cut- off grade has the main role in determination of mine layout. Mine layout actuates mineable reserve, mine life and economic profitability. Not considering the uncertainty in metal prices can lead to a non-optimal layout. In this paper optimum underground mine layout is determined by expected utilit...

â â â â â â â  this paper proposes a new forecasting model for investigating relationship between the price of crude oil, as an important energy source and gdp of the us, as the largest oil consumer, and the uk, as the oil producer. gmdh neural network and mlff neural network approaches, which are both non-linear models, are employed to forecast gdp responses to the oil price changes. the resul...

Many factors such as political events, general economic conditions, and traders' expectations may have an influence on the stock market index. Ther...

This working paper analyzes the gold price dynamics on the basis of methodology developed by Didier Sornette. Our calculations indicate that this dynamics is close to the one of the " bubbles " studied by Sornette and that the most probable timing of the " burst of the gold bubble " is April – June 2011. The obtained result has been additionally checked with two different methods. First of all,...

We assess the benefits of sharing demand forecast information in a manufacturer–retailer supply chain, consisting of a traditional retail channel and a direct channel. The demand is a linear function of price with a Gaussian primary demand (i.e., zero-price market potential). Both the manufacturer and the retailer set their price based on their forecast of the primary demand. In this setting, w...

The importance of disturbances in financial markets for real economic activity and the positive association between price level and output movements typically are explained by appeal to a combination of nominal aggregate demand shocks (particularly money-supply shocks) and rigid prices. We argue that this view is inconsistent with evidence for short-run responsiveness of prices and gold flows t...

Electricity price forecasting has been a booming field over the years, with many methods and techniques being applied different degrees of success. It is great interest to industry sector, becoming must-have tool for risk management. Most forecast electricity itself; this paper gives new perspective by trying dynamics behind price: supply demand curves originating from auction. Given complexity...
