Energy consumption management in textile finishing plants: A cost effective and sequence dependent scheduling model

This study focuses on managing energy consumption and reducing energy costs in textile finishing plants with an effective scheduling approach, which consists of sequence dependent set-up times, sequence dependent set-up energy usages and time-of-use energy tariff. The finishing plants are typical examples of the flexible job shops. Therefore, a novel energy saving mixed-integer linear programming model is proposed for the sequence dependent flexible job shop scheduling problems in this study. The proposed model comprises an extended cost function that has a quaternary structure for tackling actual scheduling problems. The capability of the developed model is evaluated with actual manufacturing data
