Yoshihiro Tanaka · Institutional Repositories DataBase (IRDB) · 1993
In this paper, a necessary and sufficient condition for the solution set of a system of linear interval equations to be convex is given.It is also discussed the relation between the convexity and feasibility of an optimization problem.Finally, extended Leontief systems are proposed as an application of our results.
