Abstract. The work presents a new version of the so-called formal (algebraic) approach to outer<br />

interval estimation of the solution sets to interval linear systems based on Miranda theorem. The<br />

applicability scope of the new approach, quality of estimation as well as numerical methods for its<br />

implementation are discussed.<br />

Key words: interval linear equations, solution set, Miranda theorem, outer interval estimate<br />

(enclosure), formal (algebraic) approach.<br />
