A Case Study: Component placement sequencing of a turret style SMT machine Levent Kandiller, Cankaya University, Department of Industrial Engineering, Cankaya University, Ogretmenler ¨ Caddesi No: 14, 06530, Ankara, Turkey, kandiller@cankaya.edu.tr, Savas Cengel, Z. Pelin Bayindir The study aims to improve component placement sequencing of PCBs produced on a turret style SMT machine in a leading Turkish electronics company. Because of the concurrent (turret,table,feeder) nature of the machine movement, the sequencing problem is hard to solve optimally. We developed two heuristic approaches and two lower bounding schemes. The heuristic solutions are compared with optimal solutions for randomly generated PCBs, and with the lower bounds for real PCBs in the production line. Our method yielded a considerable improvement (27 %) as compared to the company’s method.
