[Sample B: Approval/Signature Sheet] - George Mason University

to replace Helicopter B (HLB), which is a system currently in the operational phase of its
life cycle, with potentially 10 more years before the retirement phase begins. If HLA is
procured, HLB will be sold to another country.
The data listed in Appendix 5 was used to populate each attribute of the model,
when applicable. For example, FTR has no rescue capability, thus the attribute A4.2
Radius of Action was not applicable to this system. On the other hand, FTR is requested
to have an A/A radar with detection capability of approximately 60 Nm, which is
considered a surveillance capability, thus, attribute A2.1 Coverage is applicable.
In summary, if the aircraft system under analysis has the capabilities required to
accomplish a certain fundamental objective, the respective attributes were populated, if
not, the attributes were left at their minimum level, yielding a utility of zero in that
particular measure.
5.2 Ranking the Alternatives
Once all the data was inserted in the LDW software, the results produced by the
model could be assessed. Figure 33 shows the ranking order between all the alternatives
under analysis.
