A Novel Local Search Integer-Programming-Based Heuristic for PCB Assembly on Collect-and-Place Machines

by: Anupam Seth, Diego Klabjan, Placid M. Ferreira; Mechanical Science and Engineering at UIUC, IEMS - Northwestern University

This paper presents the development of a novel vehicle-routing-based algorithm for optimizing component pick-up and placement on a collect-and-place type machine in printed circuit board manufacturing. We present a two-phase heuristic that produces solutions of remarkable quality with respect to other known approaches in a reasonable amount of computational time... read article »
