A model of skilled human performance in a complex laboratory task is presented. The task required human crews to perform manual and supervisory control of multiple craft to discover and process objects in a simulated world. The model could perform the task as well as the most highly skilled human crews and could be parameterized to mimic the behavior of crews that differed in both crew size and experience level. The model's 'perceptual system' consists of a set of cue-weighted functions that map displayed information directly into values indicating the appropriateness of various actions. The perceptual system processes an 'image' prediction of the environment to plan future actions. A central mechanism detects and resolves potential conflicts between the simulated craft's actions, and a hierarchically structured set of action mechanisms simulates the manipulation of interface controls. Relationships with other models of skilled performance are discussed.
