Claim One:
1. A computer-implemented method comprising: a computer system assembling in a memory a plurality of models that represent components of a value chain in a petroleum exploration and/or production project, wherein each of the models includes one or more variables, where each of said one or more variables is defined on a corresponding user-specified range; the computer system creating instantiated models by selecting for each model a value of each of the one or more variables included in that model, wherein the value of each variable is selected from the corresponding user-specified range; the computer system assembling the instantiated models into a workflow, wherein said assembling includes formatting the instantiated models for access by a plurality of user-identified simulation engines; the computer system executing the simulation engines on the workflow to generate data output; and the computer system storing the selected values of the variables and the corresponding data output from the simulation engines to the memory; the computer system repeatedly performing a set of operations including said creating instantiated models, said assembling the instantiated models, said executing and said storing.
