Using a recently developed method for the guaranteed solution of interval‐valued ODE problems, we extend the regiontransition approach for process safety analysis to continuous‐time models. This makes it possible to identify, with certainty, regions of operating space that are safe, unsafe, or lead to off‐spec product. The analysis can be done in the presence of uncertain model parameters. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
