چکیده

A typical avionics mission system of a military aircraft is a complex real-time system consisting of a mission control computer, different kinds of sensors, navigation and communication subsystems, and various displays and stores; all interconnected by a number of serial data buses. The mission capability is increasingly implemented in the mission-critical software and the robustness of this software is vital for mission success. The complexity and real-time requirements of mission systems represent major challenges to the Australian Defence Force during new acquisitions, upgrades and maintenance. This paper describes the experiences on a joint research project between the University of South Australia and Australia’s Defence Science and Technology Organisation into the modelling and analysis of avionics mission systems. The paper provides a summary of the key aspects of our previous research work on the modelling of a generic mission system using Coloured Petri Nets and the analysis of task scheduling on the mission computer. Finally, the paper briefly discusses the extension of the generic model to obtain a formal model of the mission system of the AP3C Orion maritime surveillance aircraft.

Analysis of Event-Driven Real-Time Systems with Time Petri Nets: A Translation-Based Approach

The growing complexity of modern real-time embedded systems makes it imperative to apply formal analysis techniques at early stages of system development. This paper considers formal modelling of event-driven real-time systems with Time Petri Nets, and subsequent analysis via model-checking by a simple, fully automatable translation into Timed Automata. The proposed approach is applied to a sma...
