A decentralised multi-objective scheduling methodology for semiconductor manufacturing.

This paper presents a decentralised multi-objective scheduling methodology for semiconductor manufacturing. In this methodology, a new classification method is designed based on utilisations and entropies in order to decentralise global objectives into local ones of work stations. Then, a decentralised multi-objective scheduling policy is proposed to control virtual production lines (VPLs) and machine workload. Results of numerical experiments show that the proposed methodology outperforms common rule-based scheduling policies and a compound scheduling strategy. [ABSTRACT FROM AUTHOR]
