چکیده

Abstract Consider linear systems whose input data are affine-linear functions of uncertain parameters varying within given intervals. We discuss the so-called AE solution sets of such systems, where the parameters are quantified and all universally quantified parameters precede all existentially quantified ones. Some explicit descriptions of the AE parametric solution sets are derived in the special case of parametric systems where each parameter is involved in only one equation of the system (it may occur several times within this equation). For the general AE parametric solution sets these explicit characterizations lead to some necessary conditions for nonemptiness of such solution sets. Numerical examples illustrate the theory.

Explicit Description of AE Solution Sets for Parametric Linear Systems

Consider linear systems whose input data are linear functions of uncertain parameters varying within given intervals. We are interested in an explicit description of the so-called AE parametric solution sets (where all universally quantified parameters precede all existentially quantified ones) by a set of inequalities not involving the parameters. This work presents how to obtain explicit desc...

Outer enclosures to the parametric AE solution set

We consider systems of linear equations, where the elements of the matrix and of the right-hand side vector are linear functions of interval parameters. We study parametric AE solution sets, which are defined by universally and existentially quantified parameters, and the former precede the latter. Based on a recently obtained explicit description of such solution sets, we present three approac...

Inner Estimation of Linear Parametric Ae-solution Sets

Abstract We consider linear algebraic systems A(p)x = b(p), where the elements of the matrix and the right-hand side vector are linear functions of uncertain parameters varying within given intervals. For the parametric AE-solution set defined for two disjoint index sets A, E by ΣpAE := {x ∈ R n | (∀pA ∈ [pA]) (∃pE ∈ [pE ])(A(p)x = b(p))}, an inner interval estimation [y] ⊆ Σ p AE is sought. In...

Maximal inner boxes in parametric AE-solution sets with linear shape

We consider linear systems of equations A(p)x = b(p),where the parameters p are linearly dependent and come from prescribed boxes, and the sets of solutions (defined in various ways) which have linear boundary. One fundamental problem is to compute a box being inside a parametric solution set. We first consider parametric tolerable solution sets (being convex polyhedrons). For such solution set...

Explicit Characterization of a Class of Parametric Solution Sets

Consider a linear system A(p) · x = b(p), where the elements of the matrix and the right-hand side vector depend affine-linearly on a m-tuple of parameters p = (p1, . . . , pm) varying within given intervals. It is a fundamental problem how to describe the parametric solution set Σ (A(p), b(p), [p]) := {x ∈ Rn | ∃p ∈ [p], A(p)x = b(p)}. So far, the solution set description can be obtained by a ...
