Abstract: | The Stochastic Activity Network Laboratory for Cognitive Modeling (SANLab-CM) is a new tool that incorporates stochastic operations
into activity network modeling (Schweickert, Fisher, & Proctor, 2003). In this article, we discuss the core functionality
of SANLab-CM and walk through a case study that expands a previously published single, static path model of telephone operators
interacting with customers via a workstation (from Gray, John, & Atwood, 1993) into a stochastic model that generates 55 unique
paths with different frequencies and a variety of qualitative properties. Without SANLab-CM, it would have been easy to mistake
some of the more frequent critical paths as evidence for alternative strategies for task completion. With SANLab-CM, these
critical paths can be shown to be simple emergent properties of variability in elementary cognitive, perceptual, and motor
processes. |
