Oscillations are essential for the function of numerous sys-tems in biology as well as engineering [1, 9, 12]. A common property of these systems lies in their necessity to synchro-nise and coordinate inherent chemical or physical activities based on periodically iterated trigger signals. In order to sustain a stable oscillatory signal behaviour, a cyclic pro-cess succession is required that is characterised by at least one positive or negative feedback loop. The delayed signal evaluation enables a concerted alternation between effects caused by the process chain and counteractions initiated by the feedback. External stimuli or stochasticity might affect signal oscillations resulting from a process cy-cle. Motivated by the need for an appropriate toolbox cover-ing description, simulation, and analysis of discontinuously considered biological reaction processes, we extend the concept of membrane systems [11] towards an underly-ing backtracking mechanism able to explore the nature of sustained oscillations including alternations in compart-mental structure like in the following artificial example: membrane division membrane merge complex decomposition molecular transport formation complex molecules release o
