In this paper a high-level Petri net model called M-nets (for multilabeled nets) is developed. A distinctive feature of this model is that it allows not only vertical unfolding, as do most other high-level net models, but also horizontal composition — in particular, synchronisation — in a manner similar to process algebras such as CCS. This turns the set of M-nets into a domain whose composition operations...
An important technique for fault-tolerance is that of voting on multiple instances (“versions” or “replicas”) of a system component. We consider here the application of that technique to systems of concurrent processes which interact using synchronous (“handshake”) communication. We find that having to express the voter within the usual paradigm of synchronous communication (as exhibited by e.g. CCS,...
This paper presents the syntax of a concurrent programming notation which integrates a variety of process interaction techniques, its compositional Petri net semantics via the Box calculus, and an example of using the semantics for program verification.
Abstract. This paper describes a high-level Petri net model called M-nets (for modular multilabelled nets). A distinctive feature of this model is that it allows both: unfolding, as do most other high-level net models; and composition in particular, synchronisation in a process algebraic style, turning the set of M-nets into an algebraic domain. It turns out that the composition operations of this...
