Object Oriented Modelling with Object Petri Nets
- : This paper informally introduces Object Petri Nets (OPNs) with a number of examples. OPNs support a thorough integration of object-oriented concepts into Petri Nets, including inheritance and the associated polymorphism and dynamic binding. They have a single class hierarchy which includes both to

Towards a Reflective Implementation of Object Petri Nets
-
: This paper presents the concept of
reflection, where a program modifies its own interpretation. A number of applications of reflection are examined and it becomes apparent that the technique is particularly applicable to the implementation of object-oriented lang - Cited by 1 (1 self) – Add To MetaCart

From Coloured Petri Nets to Object Petri Nets
- ion Abstract: This paper seeks to establish within a formal framework how Coloured Petri Nets can be enhanced to produce Object Petri Nets. It does so by defining a number of intermediate Petri Net formalisms and identifying the features introduced at each step of the development. Object Petri Nets

The Consistent Use of Names and Polymorphism in the Definition of Object Petri Nets
- : This paper seeks to present a more elegant and general definition of Object Petri Nets than previously. It is more general since it supports transition fusion as well as place fusion. It is more elegant because it captures all the notions of place substitution, transition substitution, place fusio

The Object Orientation of Object Petri Nets
- This paper informally introduces Object Petri Nets (OPNs) with a number of examples and discusses how this kind of Petri Net addresses a number of issues pertinent to Concurrent Object-Oriented Programming Languages. OPNs support a thorough integration of object-oriented concepts into Petri Nets,

Towards Incremental Analysis
- As the size of a formal model increases, state space analysis becomes more complex in terms of time or space or both. This complexity means that state space analysis of a formal model is often practically impossible, even for a modest sized system. Recently techniques to reduce the complexity have d

The Incremental Modelling of the Z39.50 Protocol with Object Petri Nets
- : This paper examines how object-oriented extensions to the Petri Net formalism provide flexible structuring primitives which can aid the modelling of network protocols. A key benefit is the support for incremental modelling. As a result, a protocol can be modelled as a collection of services, each

A Cooperative Editor for Hierarchical Diagrams: An Object Petri Net Model
- : This paper presents a case study on the use of Object Petri Nets. The case study is that of a cooperative editor for hierarchical diagrams. The methodology for deriving the Petri Net model is to follow an object-oriented design methodology: first we prepare the Object Model in the OMT notation of

A Catalogue of Incremental Changes for Coloured Petri Nets
- Abstract: This paper presents three forms of incremental change or refinement which are considered appropriate for Coloured Petri Nets. The intention is to recommend forms which are appropriate to Petri Nets and not primarily driven by the desire to emulate object-oriented programming languages. Nev
