摘要：
This paper considers solvability and feasibility of interval linear equations and inequalities. The new concepts of solvability and feasibility are introduced in a unified framework. Some existing concepts such as weak solvability, strong solvability, weak feasibility and strong feasibility are special cases in this framework. Necessary and sufficient conditions for checking new types of solvability and feasibility are developed. (C) 2014 Elsevier Inc. All rights reserved.
