There's one thing most everyone working in production scheduling knows: No matter which system you use, however accurately your data might be, and how much time you have spent dealing with sophisticated scheduling algorithms - production reality never follows your system's implicit or explicit model. Hence, users of any production scheduling system should not only look at how it deals with a typical or an average production schedule, but they should also ask how the system supports them when dealing with unplanned incidents.
So this is why today I'd like to show you how to deal with short-term deviations from the planned capacity (i.e. when a machine operator calls in sick for a shift, or when a machine breaks down etc.).
