Systematic Review Bi-Criteria Objective Scheduling in Flexible Flow-Shop Production

Research on scheduling has been an ongoing endeavor for quite some time, increasingly adapting to advancements in industry practices. One particularly intriguing area of study is the development of bi-criteria objectives in scheduling. This research emphasizes that scheduling considerations should transcend the producer's viewpoint to also encompass customer interests. However, investigations into bi-criteria objectives remain relatively scarce. This study undertakes a systematic literature review focused on scheduling within flexible flow-shop systems. The methodological steps include planning, selection, extraction, and execution of relevant data. Data sources are drawn from Scopus, covering the period from 1986 to 2022, with the support of the Vosviewer tool. The study aims to elucidate past research on bi-criteria objectives in flexible flow- shop systems. From the studies conducted between 2016 and 2022, a notable research gap has been identified— specifically, the potential for applying a Group Scheduling model with bi-criteria objectives that incorporates Sequence Dependent Setup Times (SDST) in the context of non-identical parallel machines, presenting promising avenues for future research.
