Implementing setup optimization on the shop floor

We develop a model and solution algorithm for sequencing production on a flexible assembly line. The model incorporates the practical considerations of printed circuit board (PCB) assembly where the goal is to reduce the time spent in setup. We discuss the practical implementation problems of integrating optimization software on the shop floor-both from an operations research and systems perspective. We describe Hewlett-Packard's successful use of the software and the limitations of production sequencing in PCB assembly.
