5.1 Populating the Model
5. VALUE MODEL RESULTS
In order to demonstrate the use of the model, a hypothetical scenario was built, in
which the decision maker has to define the priorities among a set of OCRs. The OCRs
chosen for this particular scenario are related to aircraft systems with fundamentally
different purposes and characteristics (e.g. fighters and helicopters), so that the flexibility
and scope of the model could be demonstrated.
It is important to emphasize that, when applicable, the value output of the system
requested by an OCR was compared with the value output of the system it was supposed
to replace. In this case, the value of interest for the decision context is the marginal
contribution to the BAF‘s operational capability provided by that specific aircraft system
(i.e. the difference between utilities).
On the other hand, the aircraft systems supposed to provide a completely new
capability to the BAF or to replace a system in the retirement phase of its life cycle were
not compared with any other alternative. Therefore, when this situation applied, the
utility yielded by the model was directly used in the ranking of alternatives.
An OCR is not supposed to request specific aircraft systems, but only needed
capabilities, thus the equipments used in this example are fictional. Nevertheless, data
