Optimale Liisung von Intervallgleiehungssystemen. Lineare Gleichungssysteme mit Intervallen als Koeffizienten werden untersucht. Man hat dabei zu unterscheiden zwischen der L6sungsmenge und einer IntervalleinschlieBung fiJr diese, speziell der optimalen EinschlieBung. Ist die Koeffizientenmatrix des Systems ein M-Matrixintervall, so kann man mit Eliminations-und Iterationsverfahren die optimale Einschliegung berechnen, bei der Elimination muB man zus[itzlich nichtnegative rechte Seiten voraussetzen.
Optimal Solutions of Linear Intervaisystems.There are treated linear systems, the coefficients of that are intervals. We must distinguish between the set of solutions and an intervalextension of it, specially the optimal extension. If the matrix of the system is an interval of M-matrices, methods of elimination and iteration lead to the optimal extension. With elimination the right hand sides of the system must be non-negativ.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
