Abstract:

The stage with prefinish starting at singeing, dyeing and postfinish was analyzed to study the optimized scheduling of printing and dyeing process. Dyeing is a key stage for the printing and dyeing process. A novel single stage, continuoustime and immediate batch precedence based mixed integer linear programming (MILP) mathematical model was proposed for the dyeing stage. The color relation for the products with immediate batch precedence was considered, as well as the switching cost between the two products. The objective of the scheduling included the penalty coefficients of early and tardy completion. After solving a case with the solver of ILOG Company, Gantt chart for the scheduling results indicated that the resources of printing and dyeing process were optimized by the optimized scheduling of dyeing stage. The productivity was improved, and the inventory cost was reduced.
