Verifying a medical protocol with temporal graphs: the case of a nosocomial disease.
2014
Abstract Objective Our contribution focuses on the implementation of a formal verification approach for medical protocols with graphical temporal reasoning paths to facilitate the understanding of verification steps. Materials and methods Formal medical guideline specifications and background knowledge are represented through conceptual graphs, and reasoning is based on graph homomorphism. These materials explain the underlying principles or rationale that guide the functioning of verifications. Results An illustration of this proposal is made using a medical protocol defining guidelines for the monitoring and prevention of nosocomial infections. Such infections, which are acquired in the h…
Building a new CTL model checker using Web services
2013
This Computation Tree Logic (CTL) is widely used to capture compositions of reactive systems. Model checking is particularly well-suited for the automated verification of finite-state systems, both for software and for hardware. A CTL model checker tool allows designers to automatically verify that systems satisfy specifications expressed in the language of CTL logic. In this paper we present a new CTL model checker implemented in client-server paradigm. CTL Designer, the client tool, allows an interactive construction of the CTL models as state-transition graphs. Java and C# APIs are provided for programmatic construction of large models. The server part of our tool embeds the core of the …
