1. A method comprising:

  • utilizing a computer to perform;

    (a) storing in a memory first information specifying a set of uncertainty variables that characterize uncertainties associated with a plurality of assets, wherein the first information also specifies a functional relationship between a first and a second of the uncertainty variables, wherein the first uncertainty variable is associated with a first of the assets, wherein the second uncertainty variable is associated with a second of the assets, wherein the assets are assets related to the exploration and production of one or more of oil and gas;

    (b) generating and storing values for each of the uncertainty variables, wherein said generating includes generating a value for the first uncertainty variable, and computing a value for the second uncertainty variable from the value of the first uncertainty variable based on the functional relationship;

    (c) determining for each of the assets a corresponding input data set using at least a corresponding subset of the uncertainty variable values, wherein said determining includes;

    determining a first input data set corresponding to the first asset using at least the value of the first uncertainty variable; and

    determining a second input data set corresponding to the second asset using at least the value of the second uncertainty variable;

    (d) for each of the assets, invoking execution of a corresponding set of one or more algorithms on the computer, wherein each set of one or more algorithms operates on the corresponding input data set to generate a corresponding output data set;

    (e) performing (b), (c) and (d) a plurality of times to generate a plurality of output data sets for each asset;

    (f) computing one or more statistics for each of the assets based on the corresponding plurality of output data sets;

    (g) generating resultant data based at least partially on the statistics of the assets;

    (h) displaying an indication of the resultant data on a display device.
