英文摘要： The semiconductor wafer fabrication facility is a typical complex production system. With the rapid development of semiconductor technology, its scheduling faces new challenges, such as the serious uncertainties in its production environment and complexities of its production process and constraints. As a result, efficient dynamic scheduling methods are demanded to enable rapid response to real-time running environments, meet the requirements of complex constraints and achieve anticipated performance issues. This project abstracts the mentioned requirements as a scientific problem of performance-driven closed-loop dynamic scheduling. Taking swarm intelligence, data mining and system simulation as the main tools, it puts forward a research framework of performance-driven closed-loop dynamic scheduling, consisting of generation of samples, prediction models of performance issues and adaptive dynamic scheduling methods. Firstly, break through related key technologies, such as complex data pretreating, intelligent data analysis, data-based modeling and optimization, compound priority-based scheduling, etc.; Secondly, build state-performance predictive models and (performance, state)-parameter relational models, and propose an adaptive performance-driven closed-loop dynamic scheduling method, coupling constraint satisfaction, flexible preventative maintenance with dynamic dispatching. Finally, develop a semiconductor wafer fabrication facility simulation environment integrating simulating, scenario analysis and scheduling decision support to offer samples, validate and verify the proposed methods. These research achievements enrich and advance the scheduling theory of complex production systems, provide new ideas to solve the scheduling problems of semiconductor wafer fabrication facilities, and provide a scientific basis to invent new optimal ways for the scheduling of complex production systems.
