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 ...

We study the effect of the uncertainty in the induced microseismic event locations and origin times on the inverted fluid pressure diffusivity. We use a probabilistic physical model that directly ties fluid pressure in the subsurface during the injection to observations of induced microseismic events at the monitoring receiver array to track the propagation of uncertainty in the forward model a...

Survey propagation (SP) is an exciting new technique that has been remarkably successful at solving very large hard combinatorial problems, such as determining the satisfiability of Boolean formulas. In a promising attempt at understanding the success of SP, it was recently shown that SP can be viewed as a form of belief propagation, computing marginal probabilities over certain objects called ...

This paper discusses the use of recently developed techniques and software in the numerical propagation of uncertainties in initial coordinates and/or parameters for initial value problems. We present an approach based on several validated numerical integration techniques but focusing on the propagation of boxes. The procedure uses a multivariable high order Taylor series development of the sol...

Controlling Error Propagat ion in Cooperative Communication Networks

This paper presents a non exhaustive list of different methods of uncertainty propagation when the knowledge of some parameters of physical models is represented by probability measures, and others by possibility measures or belief functions.

To evaluate the future state of river water in view of actual pollution loading or different management options, water quality models are a useful tool. However, the uncertainty on the model predictions is sometimes too high to draw proper conclusions. Because of the complexity of process based river water quality models, it is best to investigate this problem according to the origin of the unc...
