Gegenstand der vorliegenden Arbeit sind zwei praktisch und theoretisch bedeutsame Probleme, die bei just-in-time orientierter Variantenfließfertigung auftreten. Ein Problem besteht darin, den Teilebedarf in der Endmontage so konstant wie möglich zu halten ("Level Scheduling Problem"). Das...

The car sequencing problem is to find feasible sequences of product variants requiring specific options while taking care of sequencing constraints. First, a branching scheme and constraint propagation algorithms for the computation of feasible sequences are provided. Second, an algorithm is...

A flow line consists of a sequence of work places (or stations) through which one or more producta (or models) move one-way in order to be processed. Each model requires specific Operations which must be performed in a predefined Order. To be able to do so, the stations must be equipped with...

While balancing straight assembly lines is a well-studied problem, the Situation where the assembly line has a U-shaped Iayout is a still emerging research field. The advantage of these lines is that workers may simply turn around to operate at two legs of the line. Hence, there is an additional...
