Abstract
In system simulation state event descriptions and state event handling are used to model and to simulation ?discontinuous? changes of the system under investiga-tion. State events may cause simple ?jumps? of parame-ters, or complex changes of models, as in case of loss or increase of degrees of freedom. The classical method of state event handling consists of an interpolative and /or iterative method to locate the event with ongoing time ? based on the zero of the state event function. This con-tribution discusses first event classification and time-based event location algorithms, and second, it discuss-es an alternative method for state event location by change of the independent variable. This method, first suggested by Henon in 1982, makes use of the princi-ples of Poincare mappings. This alternative method is analyzed and sketched with models from the ARGESIM Benchmarks on Modelling Approaches and Simulation Techniques.
