Statistics Seminars: Using Binary Decision Diagrams in Real-time Mission Planning for Collaborating Platforms
26 October 2009 14:15 in CM221
Many platforms perform phased missions made up of several distinct, sequential phases. In order for successful mission completion the platform must operate successfully throughout all of these phases. Increasingly, platforms are required to perform tasks in collaboration in order to achieve some overall mission objective. Each of the individual platforms performs its own phased mission, part of which is a task or tasks that contribute to the overall mission objective. Having the capability to provide mission prognoses for various platform configurations by accurately predicting their reliability can assist in planning the mission to be carried out. This capability is particularly important for collaborating autonomous systems, such as unmanned aerial vehicles (UAV), which must be able to react quickly to changing mission
circumstances and reconfigure their future actions accordingly.
Fault Tree Analysis (FTA) and Binary Decision Diagrams (BDD) have been used in the past to analyse the failure probability of individual platforms which perform phased missions. This presentation will demonstrate the value of a recently-developed BDD approach to phased mission analysis. In particular, it will be shown how this BDD approach can meet the requirements of a mission planning process for systems of collaborating platforms.
