Produktionsplanung bei Variantenfließfertigung: Planungshierarchie und Elemente einer Hierarchischen Planung

Abstract

Überblick ■ 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 Produkte (Mass-Customization) zugänglich gemacht. ■ Bisherige Forschungsarbeiten konzentrieren sich (mit wenigen Ausnahmen) entweder auf die lang-bis mittelfristige Fließbandabstimmung oder die kurzfristige Reihenfolgeplanung. Ansätze, welche das Zusammenspiel der beiden Planungsprobleme oder gar die komplette Planungshierarchie einer Variantenfließfertigung betrachten, sind rar. ■ Dieser Aufsatz betrachtet wichtige Elemente eines Hierarchischen Planungssystems für die Produktionsform der Variantenfließfertigung, bestehend aus den folgenden Planungsaufgaben: (i) Erstinstallation der Fließlinie, (ii) Produktionsprogrammplanung, (iii) Rekonfiguration des Fließsystems, (iv) Reihenfolgeplanung und (v) Resequencing. 759

Anticipating technical car sequencing rules in the master production scheduling of mixed-model assembly lines

“…In this model, the sequencing rules for the model options are not considered. Boysen (2005) and Boysen et al (2007Boysen et al ( , 2009a) develop a basic mixed-integer programming model for master scheduling (MS-B) that, like Bolat's model, minimizes total costs by deviation from the due date. As an extension, they consider T planning periods and assume that costs for the deviation of an order from its due date increase linearly in terms of time, causing inventory costs for early production and penalty costs for late delivery.…”

Sequencing mixed-model assembly lines: Survey, classification and model critique

“…This presupposes that the model sequence is determined for a comparatively long planning horizon (for an example see Bergen et al, 2001). In the automobile industry model sequencing is conducted once per day or shift (see Boysen et al, 2006d). Within such short time frames due dates seem to be of minor relevance, and are mainly influenced by preceding planning tasks like master scheduling which specifies the shift a model is produced in (see Ding and Tolani, 2003;Bolat, 2003;Boysen et al, 2006d).…”

“…It can thus be more meaningful to generally anticipate the sequencing decision at the higher planning level as part of a hierarchical planning approach (Domschke et al, 1996;Scholl, 1999, ch. 3.4;Boysen et al, 2006d). Table 5 summarizes the hybrid approaches presented in literature by stating the (hierarchical) tupel-notation, additional aspects (if present) and the respective methodological contribution (see section 3.3.…”

A method for the hierarchical planning of the structure, dimension and material requirements of manufacturing systems

“…To the largest degree, the enterprise realisation system in this approach is equivalent to the layer Operational Control in the model of Anthony (1965). Boysen et al (2007) introduce a hierarchical planning method for variant flow produc- tion. This approach is geared directly towards the requirements of variant flow production as faced by the automotive or electronics industries.…”

“…This approach is geared directly towards the requirements of variant flow production as faced by the automotive or electronics industries. The planning tasks tackled by the model of Boysen et al (2007) differ from the planning tasks as derived in Section 2.1. Gebhard and Kuhn (2007) design a two-step hierarchical planning method for manufacturing planning.…”
