Improving the Modeling, Simulation, Improving the Modeling, Simulation, and Analysis of Conflictsand Analysis of Conflicts
• Motivation: Political, economic, military as well as terrorist conflicts are the most destructive elements of the modern world.
– Yet, there is a lack of simulation-based computational frameworks and PSEs that are able to express realistic assumptions, postulates, theories, and dynamics that are explicitly drawn from conflict theory and behavioral sciences.
• Need to view conflicts as complex social interaction systems
to understand the characteristics, parameters, and conditions of various types of conflicts to facilitate their computational modeling.
to expand our horizons in modeling and simulation of conflicts from basic dilemmas to realistic complex conflict processes.
to advance the state of the art of simulation science and methodology to better deal with conflicts.

Conflict SystemsConflict Systems
• Structure: Conflict requires at least two parties or two analytically distinct units or entities with mutually exclusive and/or mutually incompatible values, goals, and objectives.
• Dynamics: Conflict requires interaction among parties. As such, conflict relations constitute a fundamental social interaction process.
ConflictStructure Dynamics
Context
• Context is the environment within which the conflict occurs (i.e., task structure, situation, institutions, culture, spatial model of the physical environment) influence the way conflict unfolds toward increasing escalation or de-escalation.

Conflict Systems - The StructureConflict Systems - The Structure
Structural Components of Conflict Systems
– Parties and their characteristics – their values, motivations; aspirations, objectives; their beliefs about conflicts, including their conceptions of strategy and tactics.
– Relations between parties – their attitudes, beliefs, and expectations about one another
– The structure of the issue – scope and formulation.
– The strategy and tactics employed by the parties in the conflict in assessing the one another’s utilities, subjective probabilities; use of promises, rewards, incentives.

A Three-Tier Agenda for Advancing A Three-Tier Agenda for Advancing Computational Peace and Conflict StudiesComputational Peace and Conflict Studies
(1) Advancing the Computational Modeling of Conflict Systems: Agent theory enables modeling actions, dynamics involved in changing preferences and utility, attitudes, objectives, goal-driven behavior, as well as social guiding principles (i.e., norms, culture).
(2) Advancing Behavioral Realism in the Simulation of Conflicts (i.e., Conflicts entail anticipatory behavior: Human behavior and third party interventions are predicated on the perceptions about the plausible future states of conflicts).
(3) Advanced Simulation Methodologies for Conflict Systems (Conventional methodologies lack the flexibility and adaptivity to appropriately deal with multi-aspect, multi-stage, and uncertain social phenomena).

II- Behavioral Realism in the Simulation of Conflict SystemsII- Behavioral Realism in the Simulation of Conflict Systems
Improving Behavioral Realism in the Simulation of Conflicts (adaptivity, pro-activity):
– Anticipation is a pervasive factor that surrounds many realistic and interesting intelligent processes embedded in social systems, as well as symbolic systems. Conflict are driven by perception and anticipation.

Simulating Anticipatory SystemsSimulating Anticipatory Systems
• Conflicts entail anticipatory behavior: Third party interventions are predicated on the perceptions about the future (undesirable) states of conflict.
• Predictive models for the avoidance of wars and crises are already available: AI Methods in Conflict Avoidance and Prevention of Crises and Wars - http://www.oefai.at/oefai/aisoc/peace.html.
Issues: How can anticipatory behavior improve social agent interaction? How do anticipations influence attention? How can perception and forecasting be used to realize anticipatory behavior? What is the role of anticipations on motivations and emotions?
© Yilmaz-Ören - 2004-07-25 “Conflict Systems” 18
The Social Psychology Factor in ConflictsThe Social Psychology Factor in Conflicts
• Behavioral orientations are based on the uncertainties with respect to social environment, cognitive schemas and attribution mechanisms, the state of emotional arousal, and current moods.
• Adapting option preferences and utilities based on emergent cognitive and emotional states would be critical to allocate utilities and payoffs for the action tendencies of agents.
• The action tendencies are based on the cognitive expectancies, norm values, trust, and motivational orientations leading to cooperation or competition.

Dynamic Model and Simulation Updating Dynamic Model and Simulation Updating for Exploring Complex Conflict Phenomenafor Exploring Complex Conflict Phenomena
• For most realistic complex phenomena the nature of the problem changes as the simulation unfolds. – Conventional methodologies lack the flexibility and adaptivity to
appropriately deal with multi-aspect and multi-stage phenomena.
– Need to view available knowledge as being contained in the collection of modeling experiments that become plausible and viable given what is known or learned.
• Problem: Run-time switching of models based on – interpretation of emergent, potentially unforeseen conditions
• to facilitate dynamic run-time model update and replacement for (simultaneous) experimentation with multiple simulation models.

Scenario: An inspection team under the command of the team of participants is at a weapons storage site in a fictional city. The inspection team discovers that weapons from the site are missing and that a hostile crowd is forming around them. As the inspection team radios for help, the members of the command staff must prepare and launch a rescue operation. Evidence begins to mount that the weapons were stolen by paramilitary troops who are motivating the hostile crowd. As additional paramilitary troops stream into the town, the command staff must overcome a series of obstacles in order to rescue the inspection team without incident or injury – A scenario from (Gordon and Iuppa 2003).
• Can we foresee all moves in a conflict? What if the original training scenario did not foresee a trainee decision that can result in civilian casualty?

• How can we provide to trainers as much freedom as possible, while assuring that the training goals are achieved by exerting control on the scenario flows?

WhyWhy and and When When Dynamic Model/Scenario Update is Needed?Dynamic Model/Scenario Update is Needed?
• Changing Scenarios: For most realistic social dilemmas, the nature of the problem changes as the simulation unfolds.
• Ensembles of Models: Our knowledge about the problem (i.e., conflict) being studied may not be captured by any single model or experiment.
• Uncertainty: Adaptivity in simulations and scenarios is necessary to deal with emergent conditions for evolving systems in a flexible manner.
• Exploration: As simulations of complex phenomena are used to aid intuition, dynamic run-time simulation composition will help identify strategies that are flexible and adaptive.

Toward Multisimulation with Dynamic Simulation UpdatingToward Multisimulation with Dynamic Simulation Updating
• Multisimulation (or multisim, for short) is simulation of several aspects of reality in a study. It includes
•simulation with single aspect multimodels, •simulation with multiaspect models, and •simulation with multistage models.
• Simulation with sequential multimodels allows computational experimentation with several aspects of reality.• Simulation with multiaspect models (or multiaspect simulation) allows computational experimentation with more than one aspect of reality simultaneously. • Simulation with multistage models allows branching of a simulation study into several simulation studies

(1) Select one of them and ignore others. This approach is similar to many cases in traditional simulation where implicit assumptions are not brought to the users attention. (This alternative is not a good one and definitely is not our choice.)(2) Perform an ordered simulation in breadth or depth first manner with alternative contingency models. (In this case, the user cannot easily and intuitively follow the consequences of alternative simulation studies.)(3) Select multisimulation branching (for all or some of them) and observe (visually or through metrics) behavioral and/or structural developments in simulation studies executed in parallel.
