A mixed-model assembly line requires the solution of a short-term sequencing prob-lem which decides on the succession of different models launched down the line. Afamous solution approach stemming from the Toyota Production System is the socalled Level Scheduling, which aims at distributing the...

Assembly line balancing problems (ALBP) consist of distributing the total workload for manufacturing any unit of the productsto be assembled among the work stations along a manufacturing line as used in the automotive or the electronics industries.Usually, it is assumed in research papers that,...

In today's mixed-model assembly production, there are two recent trendsin particular, namely increasing vertical integration and the proliferation ofproduct variety, which more and more shift focus to an ecient just-in-timepart supply. In this context, many automobile manufacturers set up...

Rail-rail transshipment yards are an emerging and more ecient alternative totraditional shunting yards. Instead of a time-consuming reshuing of railcarsvia shunting hills, in these modern yards, huge gantry cranes tranship containersbetween different freight trains. As multiple cranes process...

At rail-road transshipment yards, gantry cranes move containers from freighttrains to trucks and vice versa. They constitute important entities in today'sintermodal transportation systems. Real-world yards are often partitionedinto several disjunct crane areas, so that crane interferences during...

Die hohen Anforderungen an heutige Wertschöpfungsnetzwerke in Bezug aufFlexibilität und Lieferbereitschaft stellen die Distribution vor die Aufgabe, Güterimmer häufiger und in immer kleineren Mengen ausliefern zu müssen. Ein Ansatz,diesen Forderungen auf möglichst wirtschaftliche Art und...

The generation of leveled production schedules is of high impor-tance for mixed-model assembly lines whose parts and materials are suppliedjust-in-time by multi-level production processes. The Output Rate Variatonproblem is the standard mathematical representation of this complex levelscheduling...

Mixed-model assembly lines are widely used in a range of production settings,such as the nal assembly of the automotive and electronics industries,where they are applied to mass-produce standardized commodities. One ofthe greatest challenges when installing and reconguring these lines is thevast...

Trotz intensiver Fördermaßnahmen für die Bahn durch den Bund und die EU verlagert sichdas Transportaufkommen immer weiter in Richtung der Straße. Nachteile der Bahn bestehenetwa in einer geringeren Durchschnittsgeschwindigkeit und Zuverlässigkeit sowie einergeringen Flexibilität. Durch die...

A production system which consists of a number of parallel assembly lines is considered. Oneach line a certain product is manufactured observing a common cycle time. By arranging thelines in a favourable manner, it is possible to increase efficiency of the production system bycombining stations...
