Introduction The BDI (Belief, Desire, Intention) model of agency is a popular architecture based on Bratman's (Bratman 1987) theory of practical reasoning. There are numerous implementations based on the BDI architecture such as PRS (Georgeff & Ingrand 1989) and JACK , which are used for both academic and industrial purposes. An important aspect of BDI style systems is that they execute as they reason, and so avoid the possibility of the reasoning being outdated, due to environmental change, by the time execution happens. This makes them useful for many complex and dynamic environments, such as Unmanned Autonomous Vehicles (UAVs) and Air Traffic Management, due to their ability to cope well with changes, making adjustments as they go in terms of the steps chosen. They are also very fast, and therefore well suited to systems needing to operate in real time, or close to real time environments. However, there are no generic mechanisms in BDI systems to do any kind of look-ahead, or pl
