For now, this is only an intellectual consideration that can eventually help to get a better grasp of a problem. One Currently, one has to describe the whole problem in the description file regardless of these three parts. Moving forward on a "market model toolbox" and on automatically infering the computation graph for the criteria are two paths that could significantly improve the efficiency of OE deployment.
The figure below attempts to synthetize these three aspects of a typical pricing optimization problem.
