“…The estimation of the duration of production activities could be inaccurate, as well as their resource needs, the availability of machines, workers -or production resources in general -could vary, the supplying of raw materials or work-in-progress products could be late in relation to the scheduled time, new activities like rush orders or reworks could need to be executed with a higher priority (Cao et al, 2001;Alfieri et al, 2011;Makris and Chryssolouris , 2010;Mourtzis, et al, 2012;Nonaka, et al, 2012;Attia et al, 2014;Mogre et al, 2014). Hence, robust scheduling approaches have been developed, aiming at protecting the performance of a schedule by avoiding or mitigating the impact of uncertain events.…”
