ABSTRACT
Possible variations of internal parameters are defined by the conditions of components’ physical realizability, and their specifications. The constraints for these parameters variations represent a bounding box:
i i i .{ }x x i n: ≤ ≤ ,x ∀ = , , ,max (2)
The inequalities (1) define a region Dx in the space of design parameters
= .{ (∈ : ≤ ) }≤min maxx (3)
Dx is called the Region of Acceptability (RA) for the system. Figure 1 illustrates such a region.
