2.5.4 Functional Modeling and Analysis
ОглавлениеThe objectives of a functional analysis are to
1 Identify all the functions of the item.
2 Identify the functions required in the various operating modes of the item.
3 Provide a hierarchical decomposition of the item functions (see Section 2.5.5).
4 Describe how each function is realized and provide the associated performance requirements.
5 Identify the interrelationships between the functions.
6 Identify interfaces with other systems and with the environment.
Functional analysis is an important step in systems engineering (Blanchard and Fabrycky 2011), and several analytical techniques have been developed. We briefly mention two of these techniques: Function trees and SADT / IDEF 0.
