We investigate the problem of the construction of small-size universal Petri nets with inhibitor arcs. We consider four descriptional complexity parameters: the number of places, transitions, inhibitor arcs, and the maximal degree of a transition. Each of these parameters is aimed to be minimized, a special attention being given to the number of places. We give several constructions that highlight interesting trade-offs. Using equivalencies between models our results can be translated to vector addition systems with zero check, multiset rewriting with forbidding conditions, or to P systems with inhibitors.
