production planning of an open-pit mine is a procedure during which the rock blocks are assigned to different production periods in a way that leads to the highest net present value (npv) subject to some operational and technical constraints. this process becomes much more complicated by incorporation of the uncertainty existing in the input parameters. the commodity price uncertainty is among ...

In the context of open-pit mine planning, uncertainties including commodity price would significantly affect the technical and financial aspects of mining projects. A mine planning that takes place regardless of the uncertainty in price just develops an optimized plan at the starting time of the mining operation. Given the price change over the life of mine, which is quite certain, optimality o...

This paper studies the macroeconomic effects of commodity price uncertainty (CPU) shocks. Using Australia as a case study, an econometric-based CPU index is proposed to reveal that has experienced unprecedented increase in from market recently. Evidence VAR model shows shocks have larger recessionary impact than other relevant such financial, economic and trade policy uncertainty. The empirical...

uncertainty in the financial market will be driven by underlying brownian motions, while the assets are assumed to be general stochastic processes adapted to the filtration of the brownian motions. the goal of this study is to calculate the accumulated wealth in order to optimize the expected terminal value using a suitable utility function. this thesis introduced the lim-wong’s benchmark fun...

Push back design as a complex task, is one of the major steps in the open pit mines planning. Push backs can be generated by varying economic factors such as commodity price, mining cost, processing cost, etc. Another important issue in generating push backs is grade uncertainty, which can cause the problem be more complex. Conventional methods of push back design ignore grade uncertainty. To o...

Commodity storage-assets can be either physical storage-facilities, or contracts guaranteeing their use. Merchants employ them to support their commodity-trading activities in wholesale markets, which are characterized by notoriously volatile prices. Managing a storage asset requires determining an inventory-management policy, which, given a realization of the commodity price, consists of choos...

This article examines the impact of commodity price uncertainty on U.S. economic activity. Our analysis indicates that in agricultural, energy and metals markets depresses activity United States. Uncertainty shocks agricultural have a more long-lasting dampening effect its components, when compared to oil shocks. Finally, we show accounting for effects macroeconomic monetary factors, negative d...
