Formal Analysis of Medical Systems using Multi-Agent Systems with Information Sharing

Abstract

Improving safety is a main objective for medical systems. To assist the modelling and formal analysis of medical systems, we define a language for multi-agent systems handling information, timed communication, and timed migration. We use a simplified airway laser surgery scenario to demonstrate our approach. An implementation in Maude is presented; we use the strategies allowed by Maude to guide the rules application in order to decrease substantially the number of possible executions and results in the highly nondeterministic and concurrent multi-agent systems. Finally, we present how the executable specifications can be verified with the model-checking tools in Maude to detect the behavioural problems or desired properties of the agents.
