Table 1: Planning and scheduling models dealing with uncertainty in steel production. There are two special cases: the solution proposed by [PERSON] et al. 2019 which covers all the processing units within the steel process and [PERSON] and [PERSON] [38] who developed a generic multi-agent framework for steel production scheduling, without associating it to a specific process step.
