Workshop Simulation with Petri Nets

Petri nets were introduced by C.A. Petri as a "finitary combinatorial model of event topology which, is in close correspondence with the models of modern physics, is capable of describing total information flow, and has proven superior to some conventional models both in construction and in analysis of systems of complex organization". Although many other models of concurrent and distributed systems have been developed, Petri nets are still considered "a central model for concurrent systems with respect to both the theory and the applications" due to the natural way they allow to represent reasoning on concurrent active objects which share resources and their changing states.

The huge amount of work invested in making the modelling power of Petri nets formalism more and more intensive, led to a continuous evolution of this area, such that "Petri nets" is currently a generic name for a whole class of models divided into three main layers (ranging from Elementary Net Systems and Place/Transition nets to traditional High Level nets and High Level nets with abstract data types). For the performance evaluation of the modelled system, time execution and/or stochastic processes have also been considered, leading to important extensions to the above general Petri nets classification: Timed and Stochastic Petri nets. 

Petri nets are widely considered as an operational (rather than denotational) formalism for Discrete Event Systems. They have proven to be useful in solving difficult discrete-event problems in a variety of application domains such as in software engineering, operating systems, databases, communication and co-operation protocols in distributed systems, manufacturing systems, defence command and control, business processes and telecommunications, etc.
As investigations in this area show, Petri nets also cover a large number of currently active research areas. Despite the great amount of work and achievements, much effort is still to be done to meet the applications requirements.

This workshop is intended to provide a forum for the presentation and discussion of original ideas, recent results and achievements by researchers, students and system developers on issues and challenges related to the above domain.
We invite to submit original contributions addressing, but not limited to one of the following topics:

SIMULA Workshop: "SIMULA past, present and future"

   SIMULA is the first OOP language and with the exception of Beta programming language, other broadly used OOP languages are conceptual subsets of SIMULA. The standard was defined in 1967, that's why the language used to be called SIMULA 67. The basic ideas were presented at the IFIP Working Conference "Simulation Programming Languages" in Oslo in 1967, the proceedings were published 35 years ago in 1968. SIMULA (SIMple Universal LAnguage) as such is a general object-oriented language. Its system classes Simset and Simulation add the knowledge of linked lists and time processes making SIMULA a process-oriented simulation language.
The workshop would concentrate on the SIMULA's advanced OOP features that cannot be found in other OOP languages and on its simulation capabilities. The so-called main classes (nested classes that contain other local classes) that can be further specialized represent modularity achieved by using the OOP capabilities of the language. The system class Simulation will be enhanced to contain classes supporting transparent statistics and classes oriented to the simulation of queueing networks. SIMULA implementation for PC computers is now freely available, so the participants of the workshop will get tools and knowledge to create fast their own simulation models. Submit your proposal here
