Abstract: The performance of an enterprise largely depends on the schedule of its resources. A good schedule may increase the output rate and reduce the production costs. Therefore, in this paper, we consider the cyclic schedule of hoist activities in automated electroplating lines which is commonly known as cyclic hoist scheduling problem (CHSP). The CHSPs appear in the manufacturing facilities to achieve a mass production and to search a repetitive sequence of moves for the hoist. In such kind of lines, hoist is used for moving electroplates through a line of tanks containing chemical baths. In this paper, we first study the impact of non-fixed processing time in cycle duration and then we extend our elaborated two-degree cyclic model to a more complex configuration of the production lines.
