A Model of Human Problem Solving in Dynamic Environments

Human problem solving is considered in terms of the effects of the environment being dynamic. For example, the impact of having to operate a system while also trying to diagnose failures is discussed as well as several related issues. A general structure is proposed for modeling human problem solving in such environments. A realization of this general structure within a particular rule-based computer program is discussed. Results are presented from applying this program to modeling human problem solving in a process control task.
