  In this work we propose a new kind of parameterized outer estimate of the
united solution set to an interval parametric linear system. The new method has
several advantages compared to the methods obtaining parameterized solutions
considered so far. Some properties of the new parameterized solution, compared
to the parameterized solution considered so far, and a new application
direction are presented and demonstrated by numerical examples. The new
parameterized solution is a basis of a new approach for obtaining sharp bounds
for derived quantities (e.g., forces or stresses) which are functions of the
displacements (primary variables) in interval finite element models of
mechanical structures.
