In this document we give an overview of the CO-OPN/1.5 (Concurrent Object-Oriented Petri Nets) specification language and describe the features of each tool provided in the SANDS/1.5 (Structured Algebraic Net Development System) development environment. Th ...
SANDS is a development tool based on structured algebraic nets. The environment is composed of the following features: - Algebraic nets allowing the definition and use of structured tokens by means of algebraic specifications. Apart from reducing the si ...
Although many temporal models have been proposed in the literature, there is still need for a conceptual model capturing the essential semantics of time-varying information that is free of implementation concerns. This paper first discusses important crite ...
New architectures of telecommunications networks like the Intelligent Network (IN) proposal allow an ever easier way to introduce new services into a network. However, this facility and the short delays that can be achieved between the first informal speci ...
Numerous proposals for applying temporal logic to the specification and verification of object-oriented systems have appeared in the past several years. Although various temporal models have been proposed for the requirements analysis of object-oriented di ...
Based on the notion of event-based behavioral abstraction (EBBA) we specify properties of object-oriented distributed systems in linear time temporal logic. These properties are then observed at system run-time and it is checked whether or not the system v ...
The concept of event-based behavioral abstraction (EBBA) is shown to facilitate the Design For Testability (DFT) if the set of events is well-chosen. We provide a predefined set of events which, together with linear-time temporal logic, can be used for exp ...
The approach to improve confidence in Services Implementation presented in this paper is based on the addition of a Service Modeler and Verifier Function (SMV) in the environment where the service take place. The SMV, combined with a test scenario, is able ...
We present a method for proving properties of Petri nets expressed in the branching time temporal logic CTL. The framework of CTL formulae, viewed through the notions of predicates and predicate transformers in the context of Petri nets, is also presented. ...
