MAS are used for coordinated defense systems in complex dynamic environments. These systems deal with operational problems that are extremely complex, require processing increasing data volumes, in dynamic environments, and that face trade-offs between competing priorities and differing optimization and solutions. MAS are an easy to understand way of decomposing a complex system into smaller distributed systems of individual agents that have conflicting goals and compete for resources. Multi-Agent Systems reach decisions that enable optimal solutions by conveying information to each agent and brokering a decision through collaborative and coordinated decision making.
