IO 09 Science and Practice

Picture 9AOS Group Research Director,  Dr Rick Evertsz, presented the keynote address at the opening of the Industrial Gaming stream of the Integrated Operations conference in Trondheim, Norway. The 5th International Conference on Integrated Operations in the Petroleum Industry (29th – 30th September) covered a wide range of topics, from intelligent petroleum fields to autonomous control of sub-sea drilling rigs.

Dr Evertsz’s topic, “Realistic Modelling of Cognition and Emotion in a Suicide Bomber Scenario”, focused on the general requirements for human behaviour representation in synthetic environments, the CoJACK BDI (Beliefs/Desires/Intentions) cognitive architecture and a suicide bomber scenario.

Most current approaches to behaviour modelling use the scripting language that is embedded in the synthetic environment. These languages were not designed for human behaviour modelling, and consequently they lead to models that are cumbersome to write and difficult to debug. Furthermore, SMEs (Subject Matter Experts) typically cannot directly critique the models.

What is needed is a behaviour modelling language that is easy to program, straightforward to debug, understandable by SMEs, and constrained by the literature on psychology. CoJACK fills this gap in current capability. It consists of an intuitive, graphical programming language that is easy for SME's to inspect and critique, an underlying cognitive architecture that constrains the real-time performance of the models, and a moderator layer that enables the inclusion of models of affect and physical factors, such as morale, fear and fatigue.

Picture 9Although the suicide bomber scenario that was demonstrated is not directly relevant to the oil industry, the underlying principles are. CoJACK could be used to drive virtual actors in a training environment where human emotion plays a part in decision making; for example, evacuating a plant during an emergency. An emergency evacuation scenario could be developed that highlights how plant layout impacts the ability to evacuate rapidly when fear is affecting the decisions of those trying to escape.

This kind of flexibility and richness is only possible when a modelling tool, such as CoJACK, is used to build the virtual actors. Also, validated models of moderators, such as fear, can then be re-used across different scenarios and application areas.
