Jump Transitions in Second Order FSPNs
نویسنده
چکیده
In this paper jump transitions for the fluid model part in second order fluid stochastic Petri nets (FSPNs) are introduced. The extended formalism is defined, and the underlying partial differential equations are derived. With a jump a certain amount of fluid is added to a fluid place or taken out at once. This amount, the jump height, is sampled from a probability distribution. The dynamics of a model are described by second order partial differential equations that include integrals. As examples the virtual waiting time (or unfinished work) in a queueing system and a performability model of a multi-processor system are modelled.

On Markov Reward Modelling with Second Order FSPNs
In this paper second order uid stochastic Petri nets (FSPNs) will be used for modelling reward in a performability model. Two variations of the performability model are presented. In the rst one two uid places are used, one of which represents the proot (reward) obtained by operating the system and the other one the buuer, that is approximated continuously. In the second model only one uid plac...
متن کاملEquivalence and Lumpability of FSPNs
We consider equivalence relations for Fluid Stochastic Petri Nets (FSPNs). Based on equivalence relations for Stochastic Petri Nets (SPNs), which are derived from lumpability for Markov Chains, and from lumpability for certain classes of differential equations, we define an equivalence relation for FSPNs. Lumpability for the differential equations is based on a finite discretization approach an...
متن کاملModeling software systems with rejuvenation, restoration and checkpointing through fluid stochastic Petri nets
In this paper, we present a Fluid Stochastic Petri Net (FSPN) based model which captures the behavior of aging software systems with checkpointing, rejuvenation and self-restoration, three well known techniques of software fault tolerance. The proposed FSPN based modeling framework is novel in many aspects. First, the FSPN formalism itself, as proposed in [24], is extended by adding ush-out arc...
متن کاملA Taylor series expansion for H1 Control of Perturbed Markov jump Linear Systems
In a recent paper, Pan and Baaar 19] have studied the H 1 control of large scale Jump Linear systems in which the transitions of the jump Markov chain can be separated into sets having strong and weak interactions. They obtained an approximating reduced-order aggregated problem which is the limit as the rate of transitions of the faster time scale (which is a multiple of some parameter 1/) goes...

We have derived coupled systems of partial diierential equations for the transient and the steady-state behavior of FSPNs. Spectral representation of the FSPNs with a single continuous place can be a...
