Dynamic changes in manufacturing production sites make current production schedule infeasible and inaccurate. In these cases, some parts in plans consisting of production planning are changed to obtain the plans adapted to these changes. In this study, we refer to these parts as optionality in production planning. In related research about production planning, optionality is preliminary set. However, this fixed optionality may not be suitable for certain cases, such as the case of having different factories, products and so on. In this study, we have analyzed optionality in production planning so far. In this paper, we develop new replanning model based on the optionality.
