i sincerely doubt there is a software that is able to make conditional decisions and works better at that then a human being. if you come across such a software, please inform me because i'd very much like to take a look at that.
but perhaps i missunderstood and you are referring to an economical decision as done with LP models. if this is the case, you should look into PIMS (also by aspentech) or aspen.refsys (if it is avaiable by now). but these tools just calculate the optimal solution of a system of linear equations.
