摘要
The invention concerns a method for gradually deforming representations or productions, generated by sequential simulation, of a stochastic model not necessarily Gaussian of a physical quantity z in a meshed heterogeneous environment, so as to adjust them to a set of data concerning the structure or the state of the environment collected by prior measurements and observations. It consists essentially in applying an algorithm gradually deforming a stochastic model to a Gaussian vector with N mutually independent variables, which is linked to a uniform vector with N mutually independent variables by the function of Gaussian distribution so as to define productions of the uniform vector, and in using said productions to generate representations of said physical quantity z, which is set relative to the data. The invention is useful for example to display the statistic configuration of a quantity: the permeability of an underground deposit, atmospheric pollution and others.
