We study the design problem of part-orienting systems which are often employed in many manufacturing environments to orient parts of assembly or to perform operations. A part-orienting system is composed of a number of orienting devices. The problem of selecting proper design parameters for the devices and, of serially ordering them to make up the system, is addressed in this paper. The problem is illustrated through a real world example. Heuristic algorithms have been developed and computer experiments have been performed to evaluate their relative performances.
