Description
Summary:This paper describes and evaluates two general techniques to simulate human performance of procedural tasks. A procedural task is characterized as a partial ordering of task elements in which the control of task-element sequencing is represented within the task, rather than as an interaction between the task and the environment in which the task is performed. The primary concern in simulating the performance of procedures is determining the mechanism that controls task-element sequencing. Two modeling frameworks have been used to represent task-element sequencing. The first method represents the constraints on task-element sequencing directly in a network. Am second method represents sequencing constraints indirectly as a set of production rules. Both frameworks offer considerable generality and flexibility in the kinds of structures that can be represented. The relative advantages of the two methods depend upon the questions addressed by the model and the characteristics of the tasks being modeled.
