functional decomposition

[′fəŋk·shən·əl dē‚käm·pə′zish·ən]
(control systems)
The partitioning of a large-scale control system into a nested set of generic control functions, namely the regulatory or direct control function, the optimizing control function, the adaptive control function, and the self-organizing function.

functional decomposition

Breaking down a process into non-redundant operations. In structured programming, it provides a hierarchical breakdown of the program into the individual operations, or routines, that are required. See normalization.


Functional Decomposition of a Program
This example is ultra simplistic, but shows the hierarchical breakdown of the program into its constituent components.

Because of the function decomposition, the cost of collecting data is increased.
However, FBS is a brand-new product, designed by function decomposition. It takes function decomposition as a solving process, in which we keep asking "HOW".
In this paper, we investigate the application of local fractional Adomian decomposition method and local fractional function decomposition method for solving the local fractional Laplace equation [21, 22] with the different fractal conditions.
Section 3 presents briefly the local fractional Adomian decomposition method and the local fractional function decomposition method.

If we add more information and indicate in each entry what the function is that the component should have in order to play this role in the system function, then we call the resulting table a function decomposition table.
The following list relates these to the function decomposition table of the system.
Empirical Orthogonal Function Decomposition. EOF decomposition involves decomposition of a matrix X of data describing the distribution of a variable in both space and time into a spatial function V and time function T as shown in
We have analyzed spatial and temporal patterns of annual precipitation in the Weihe basin using data recorded from 1960 to 2011 at 30 National Standard Stations in the basin and surrounding area, by applying empirical orthogonal function decomposition in combination with geostatistical (semivariogram) analysis, then using the Mann-Kendall method to discriminate variation points in the precipitation series recorded at each station.
The local fractional function decomposition method structured in [11, 22], which is a coupling method of the local fractional Fourier series [21, 22] and the Yang-Laplace transform [14, 16, 18, 22], was used to solve the inhomogeneous local fractional wave equations defined on Cantor sets.
