In the paper Gaussian monoids with zero as a basis for modeling of concurrence and a kind of consistence are proposed and a notion of concurrent system is defined. The main idea is to replace the binary relation of concurrence defined on a set of activities (transitions in Petri nets, events etc.) by a more general notion of independence of multisets.
