The generation of leveled production schedules is of high importance for mixed-model assembly lines whose parts and materials are supplied just-in-time by multi-level production processes. The Output Rate Variation problem is the standard mathematical representation of this complex level...

Mixed-model assembly lines are of great practical relevance and are widely used in a range of industries, such as the final assembly of the automotive and electronics industries. Prior research mainly selected and discussed isolated problems rather than considering the whole planning process. In...

The sequence-dependent assembly line balancing problem Abstract Assembly line balancing problems (ALBP) arise whenever an assembly line is configured, redesigned or adjusted. An ALBP consists of distributing the total workload for manufacturing any unit of the products to be assembled among the...

Assembly lines are flow-line production systems which are of great importance in the industrial production of high quantity standardized commodities and more recently even gained importance in low volume production of customized products. Due to high capital requirements when installing or...

In dieser Fallstudie wird ein bekanntes Grundproblem der Beschaffungslogistik, nämlich das dynamische Bestellmengenproblem nach Wagner und Whitin (WWP), um praxisrelevante Aspekte wie dynamische Einstandspreise, Lagerkapazitäts- und Haltbarkeitsbeschränkungen sowie Schwund bzw....

Unternehmen und ihre Teilsysteme unterliegen dynamischen Veränderungen der Umwelt und ihrer eigenen Handlungsmöglichkeiten in einem zeitlich offenen Entscheidungsfeld. Diese Dynamik ist bei der Planung, d.h. der Lösung betrieblicher Entscheidungsprobleme, geeignet zu berücksichtigen. Dabei...

Previous approaches for balancing mixed-model assembly lines rely on detailed prognoses of the demand for each model to be produced on the line (model-mix). With the help of the anticipated model-mix a joint precedence graph for a virtual average model is deduced, so that the mixed-model...

Die Produktionsform der Variantenfließfertigung erlaubt es, unterschiedliche Varianten eines Grundmodells gemeinsam auf einem Fließsystem in wahlfreier Reihenfolge (Losgröße Eins) zu fertigen. Auf diese Weise wird auch der effizienten Fließfertigung eine kundenindividuelle Anpassung ihrer...

Manufacturers in a wide range of industries nowadays face the challenge of providing a rich product variety at a very low cost. This typically requires the implementation of cost efficient, flexible production systems. Often, so called mixed-model assembly lines are employed, where setup...
