| 1 | Scheduling Dual-Arm Cluster Tools With Multiple Wafer Types and Residency Time Constraints显示文摘Accompanying the unceasing progress of integrated circuit manufacturing technology, the mainstream production mode of current semiconductor wafer fabrication is featured with multi-variety, small batch, and individual customization, which poses a huge challenge to the scheduling of cluster tools with single-wafer-type fabrication. Concurrent processing multiple wafer types in cluster tools, as a novel production pattern, has drawn increasing attention from industry to academia, whereas the corresponding research remains insufficient. This paper investigates the scheduling problems of dual-arm cluster tools with multiple wafer types and residency time constraints. To pursue an easy-to-implement cyclic operation under diverse flow patterns,we develop a novel robot activity strategy called multiplex swap sequence. In the light of the virtual module technology, the workloads that stem from bottleneck process steps and asymmetrical process configuration are balanced satisfactorily. Moreover, several sufficient and necessary conditions with closed-form expressions are obtained for checking the system's schedulability. Finally, efficient algorithms with polynomial complexity are developed to find the periodic scheduling, and its practicability and availability are demonstrated by the offered illustrative examples. | Jipeng Wang Hesuan Hu Chunrong Pan Yuan Zhou Liang Li | 2020 | IEEE/CAA Journal of Automatica Sinica2020，7，3： | 2 |
| 2 | AN EXTRACTION ALGORITHM FOR A SET OF ELEMENTARY SIPHONS BASED ON MIXED-INTEGER PROGRAMMING显示文摘基本虹吸在为与 Petri 网建模的一个分离事件系统的一条僵局预防政策的发展是有用的。这篇论文建议一个算法反复地在 Petri 网络的一个类上提取一套基本虹吸,有资源(S3PR ) 的简单顺序的进程的叫的系统。在每次重复,由混合整数编程(MIP ) 方法,建议算法发现最大的未做记号的虹吸,在它分类这些地方,从分类地方提取基本虹吸,并且增加新限制以便提取下一基本虹吸。这个算法反复地执行直到没有新未做记号的虹吸能被发现。它最后获得基本虹吸的一个唯一的集合并且避免完全的虹吸枚举。理论分析和例子被给表明它的效率和实际潜力。 | Shaoyong LI Zhiwu LI Hesuan HU Abdulrahman AI-AHMARI Aimin AN | 2012 | Journal of Systems Science and Systems Engineering2012，21，1： | 1 |
