Predictive industrial scheduling addresses the generation of agendas by supposing that all the manufacturing orders and resources are given and there is no un-certainty in their behavior. Experience demonstrates that there are (i) intrinsically uncertain parameters, like processing times and costs, setup/changeover times, etc., and (ii) unforeseen events, such as machine breakdowns, rush orders, order cancellations/modifications, lack of personnel, late arrival of raw materials, etc. In fact, industrial environments are part of a globalized and competitive economy that needs to tackle volatile markets, sharp fluctuations in fuel pricing, and that is strongly affected by the perturbations of the COVID pandemic, wars, and extreme climatic incidents. This situation raises important challenges to the scheduling function, calling for proficient rescheduling abilities. On the other hand, the tremendous advances in a variety of digital know-hows, led to advanced manufacturing technologies, such Smart Manufacturing and Industry 4.0. If such technologies are properly adopted and articulated, they can pump up current reactive scheduling capabilities. Therefore, in the current context, the rescheduling do-main faces both tremendous difficulties and enormous opportunities.
