Hoist Scheduling for multi-part CHSP in complex lines' configuration

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 extend our elaborated 2-degree cyclic linear model to a more complex configuration of the production lines.
