Embodiment
[0071] Taking the lifting equipment painting workshop of a heavy machinery group as an example, the multi-objective optimization of flexible workshop scheduling is carried out. The workshop has the main equipment required for coating processing, including pre-treatment devices, cathodic electrophoresis equipment, dryers, grinders, gluing manipulators and online testing equipment. T obtained through the record data and order item table of the operation process and status on a production line in the workshop ijk , C ijk and h i and other parameters, after calculation and processing, the problem of flexible workshop scheduling with 6 workpieces and 10 equipment, and each workpiece has several processes is obtained. The specific workpiece machine information is shown in Table 1, where 1 means occupied and 0 means not used. The index values of processing cost and processing time of different equipment for different processes are shown in Table 2.
