| 英文摘要 |
| With the model of multi-variety and small-batch production applied widely, it led to frequent transient process
of cluster tools. In order to improve the production flexibility of single-arm cluster tools, the scheduling of close-down
process problem is addressed considering the time constraints of wafer residency and chamber cleaning. Firstly, a transient
scheduling rule with 1-period of cleaning operations is proposed. Resource-oriented Petri net is used to model the closedown
process of single-arm cluster tools and a rule of transition firing is introduced to avoid deadlock. Secondly, according
to the close-down process time characteristics of the system and different scheduling situations, a corresponding linear
programming model is established to achieve close-down process optimal scheduling. Finally, examples are given to verify
the feasibility of the proposed approach. The experimental results show that the scheduling scheme can effectively reduce
close-down process makespan of single-arm cluster tools and meet wafer fabrication process requirements, compared with
the virtual wafer method based on extended backward strategy. |
