E-Government Services: Comparing Real and Expected User Behavior
E-government web services are becoming increasingly popular among citizens of various countries. Usually, to receive a service, the user has to perform a sequence of steps. This sequence of steps forms a servi...

Using Event Logs for Local Correction of Process Models
During the life-cycle of an Information System (IS) its actual behavior may not correspond to the original system model. However, to the IS support it is very important to have the latest model that reflects t...

Automatic construction of systems of distributed components from nested Petri nets models
Multi-level multi-agent systems (MASs) with dynamic structure are widely used in solving important applied problems in telecommunication, transportation, social, and other systems. Therefore, ensuring correct ...

CPN tools-assisted simulation and verification of nested Petri nets
Nested Petri nets (NP-nets) is an extension of Petri net formalism within the “nets-within-nets” approach, when tokens in a marking are Petri nets wich have autonomous behavior and synchronize with the system ...

Modelling multiagent systems with the help of generalized nets of active resources
The problem of modelling infinite-state multiagent systems is considered. Formalisms based on the generalization of nets of active resources are studied. New modeling techniques are defined, namely, parametriz...

Recursive Nested Petri Nets: Analysis of Semantic Properties and Expessibility
Recursive nested Petri nets may contain marked nets, including their own copies, as their tokens. It is proved that the termination problem is decidable for recursive nested nets with autonomous elements. The ...
