<p>The deletion of the Centralized HPAS from DDG 51 Class
Flight IIA, and the development of improved, more cost
effective, dedicated subsystems via ECP 51-1216 was a
considerable effort which required a structured design
approach. The approach taken and described in this paper
closely resembled the systems develo~t process prescribed
by reference (a); deviations taken (1. e. fonnal preparation
of functional flow diagrams and detailed R&M
calculations/allocation), were carefully considered and
balanced against Program schedule and cost constraints, as
well as overall Program objectives for development of
detailed specificat10n requirements. Further, Program
direction to utilized existing, proven, and supported
hardware, coupled with limited prototype testing, reduced
the risks associated with such deviations. Moreover, this
paper demonstrated the significant influences of human
factors in the design of each new replacement subsystem; it
was shown that conslderation of such human factors
attributes as functional effectiveness, operator safety,
accessibility, and operability are fundamental to proper
system design throughout the system development process. To
this end, the objectives cited in Section 1.1 of this paper
were met.</p> / Master of Science
