| Popis: |
To solve the problem of differential maintenance demand caused by daily dynamic maintenance and periodic replacement of support rolls in large-scale hot rolling lines, a maintenance priority rule is introduced to identify maintenance judgment order of components under long distance condition and downtime constraint. A dual variable time window rule is constructed to identify whether components should be maintained and distinguish maintenance demand, and then a dynamic opportunity maintenance model is established for the system. The case study shows that the model can effectively solve the problem of differential maintenance scheduling for large-scale hot rolling lines under the constraints of maintenance resources and downtime, and has more cost advantages than the traditional time-window-based model. |
