Evaluation of complex systems

A new process is introduced for evaluating systems. Criteria are represented as a hierarchy of functions or, at a policy level, a hierarchy of policy positions. The system to be evaluated is represented as a hierarchy of its components. Elements of the system are scored against criteria using a bidirectional scale with provision for degrees of both support and obstruction. Assessment values for lowest-level elements are calculated using a series algorithm that relates composite scores uniquely to the scoring scale. Values for categories within both hierarchies are calculated from element values below them, with results presented graphically, in color.
