Modeling and simulation of operator team behavior in nuclear power plants

This paper depicts the technique of simulation for plant operators facing abnormal events within the plant “SYBORG: Simulation System for the Behavior of an Operating Group” is installed in workstations, and simulates the behavior (cognitive action, communication) of a team consisting of 3 operators. This study introduces a “mental model” that describes and illustrates how operators predict plant behavior and make decisions to prevent the deterioration of its conditions. SYBORG simulates decision making processes via communication among operators, considering human relations such as : position, personality, credibility, etc. This paper also shows some interesting results of simulation with SYBORG.
