Abstract:

Due to too much constraints and variables in process scheduling model based on uniform discrete-time representation, batch short-term scheduling based on continuous-time representation has received an intensive concern and study.In this paper a brief introduction of process scheduling was given, a short-term scheduling MILP model based continuous-time representation of printing and dyeing industry was presented after studying on short-term scheduling and production recipe of printing and dyeing.Then MILP model was translated into a solvable model described by ILOP OPL language, this model together with data of two cases from a printing and dyeing corporation in Zhejiang Province were solved by ILOG CPLEX, the results were illustrated in Gantt charts.The result shows effectiveness of MILP model of printing and dyeing process and production resources in shop floor are optimized.
