Abstract
This paper presents a production scheduling system for photographic film manufacturing industries. The scheduling system considers a hybrid flow shop, which consists of two manufacturing stages: first, the slitting of the film bulk-roll, and second, the interleaving and wrapping of the slitted sheets. In this study, several hundred final productions are produced from the film bulk-roll based on the actual demands for final products. This production scheduling system was designed as a decision support system by combining computer capability with production management. The selected performance criteria for making a schedule were ratio of setup time to processing time, work-in-process level ratio of attainable production quantity of final products to the planned production quantity. The system designed for this study showed more favourable results than the conventional system.production scheduling system hybrid flow shop
