Summary
The necessity of taking control on civil disorders has been hardly felt by all governments and military agencies after the occurrences of the last 5-6 years. Episodes such as September 11, war in Iraq and in Afghanistan have shown how nowadays the action of military and peace forces has to be devoted to sedate riots and small but potentially dangerous attacks. So the authors have been involved in a research project in cooperation with Italian and French military agencies in order to realize a simulator able to add intelligent behaviour to computer generated forces used in all training systems of NATO forces. In order to reach such complex target. Authors have modelled human behaviour by defining some important functions that can determine one action instead that one another: some of these functions are stress, aggressiveness, rage and so on. Obviously these functions are interlaced among themselves by different agents directing the simulation objects. The authors have realized different agents to be attributed to the different objects as driving entities; the system is organized in an HLA Federation that can run itself or being integrated with theatre war gaming systems. The scenario used for testing the model deals with the DEMONSTRATION/RIOT direct operation in a context where different ethnic groups; these entities represent Comportment Objects. Mutual attitudes among different groups (i.e. ethnic type A and B, ONU Forces) and type of units (i.e. gangs, militia, regular forces, terrorist etc.) are initialised for regulating the interactions, while the ROE and behavioural profiles are attributes to entities inside the area; these entities are instantiations of action objects; while psychological modifiers reproduce unit characteristics able to affects the capacity to execute missions/tasks and the related efficiency in carrying out this aspects. The entities on the field are defined as Action Objects. In the disorder area Militia units, representing different Police entities, with different attitudes respect the ethnic groups re included. The attitude profile is defined in statistical term in order to generate stochastic behaviours among groups of people / police: so it is possible to have in a group individuals with different mutual attitudes; these logic evolves dynamically during simulation based on events and actions as well on limitation of the entities due to their perception/communications.
