Um im weltweiten Wettbewerb zu bestehen, ist eine kostenminimale Fertigung unter Berücksichtigung der bestehenden Restriktionen notwendig; denn größtmögliche Produktivität ist die Voraussetzung für den Geschäftserfolg. Kai-Oliver Schocke entwickelt ein neues Lösungsverfahren für...

Gomory mixed-integer cuts are of crucial importance in solving large-scale mixed-integer linear programs. Recently, there has been considerable research particularly on the strengthening of these cuts. We present a new heuristic algorithm which aims at improving Gomory mixed-integer cuts. Our...

The nested L-shaped method is used to solve two- and multi-stage linear stochastic programs with recourse, which can have integer variables on the first stage. In this paper we present and evaluate a cut consolidation technique and a dynamic sequencing protocol to accelerate the solution...

Traditionally, two variants of the L-shaped method based on Benders’ decomposition principle are used to solve two-stage stochastic programming problems: the aggregate and the disaggregate version. In this study we report our experiments with a special convex programming method applied to the...
