Abstract: In semiconductor manufacturing, due to product customization, a cluster tool is frequently required to switch from processing one type of lots to another, leading to ubiquitous lot switching periods, during which consecutive lots are processed concurrently. As a different lot mix often results in different lot completion times, it is challenging to obtain an optimal processing sequence of lots to minimize the makespan for a flexible flow shop with two stages where each stage consists of identical cluster tools. In this paper, an efficient backward earliest-starting strategy is proposed based on which procedures are designed for calculating the completion time of each lot ta­king into account the different lot mixes. A biased random key genetic algorithm (BRKGA) is proposed to compute high-­quality schedules using these completion times.

Fajun Yang received the the Ph. D. degree in Mechanical Engineering from Guangdong University of Technology, Guangzhou, China, in 2016. From 2015-2016, he was a Visiting Ph. D. Student with New Jersey Institute of Technology (NJIT), Newark, NJ, USA. From 2017-2019, he was a Research Fellow with Nanyang Technological University, Singapore. He is currently a Postdoctoral Researcher of Humboldt Research Fellowship, Germany. He has over 30 refereed papers and patents and received the “2021 Hsue-shen Tsien Best Paper Award” of IEEE/CAA Journal of Automatic Sinica and the “Overseas High-level Talents ‘Young Experts Program’ of Shanghai in 2021. His interests are Production and Operation Management, Supply Chain and Logistics Management, Modeling and Scheduling on the Intelligent Manufacturing Systems, Multi-objective Optimization, Big Data and Machine Learning.
