In the proposed formulation, the fluid jump arc of Second order Fluid Stochastic Petri nets, which takes deterministic jump height, is introduced for the sake of modeling impulse rewards. In order to model non-Markovian stochastic systems, the fluid jump arc is combined with the flush-out arc. As a result the fluid jump arc as a modeling primitive has the function of emptying in zero time the existing fluid from the continuous place connected with it.
