from real aircraft, available in open sources 119 , was used to populate the model in order to
give more credibility to the results.
Table 4 shows the hypothetical aircraft systems used in this example (see
Appendix 5 for a detailed description of their characteristics):
Table 4. Aircraft Systems.
Requested systems Current systems
Fighter (FTR) Retirement Phase
Cargo (CGO) Retirement Phase
Unmanned Aerial Vehicle (UAV) Non existent
Anti-submarine Warfare(ASW) Non existent
Helicopter A (HLA) Helicopter B (HLB)
In this hypothetical decision context, the aircraft systems called Fighter (FTR) and
Cargo (CGO) are supposed to replace systems that are in the retirement phase of their life
cycle. Therefore, the related OCRs are requesting systems to replace capabilities that will
be lost very soon. As explained earlier, in this case the result yielded by the model will be
used in the ranking of alternatives.
Similar rationale is applied to OCRs requesting aircraft systems that will bring
new capabilities to the BAF. This is the case of the aircraft systems identified as Anti-
submarine Warfare (ASW) and Unmanned Aerial Vehicle (UAV).
The aircraft system Helicopter A (HLA) fits in the case where the marginal
improvement needs to be determined. It simulates the situation where an OCR requests a
new aircraft system due to a good market opportunity. In this example, HLA is supposed
