(systems engineering)
A graph-theoretic representation of a decision, which may include four types of nodes (decision, chance, value, and deterministic), directed arcs between the nodes (which identify dependencies between them), a marginal or conditional probability distribution defined at each chance node, and a mathematical function associated with each of the other types of node.

Warships have sensors (such as radars and lookouts), decision nodes (combat information centers), and actors (the warship's weapons), all connected together with some form of communications, which we generically call "local area networks" But we do not need to get exotic; our own nervous systems are classical information systems--sensory nerves, a decision node, and motor nerves to actuate muscles.
