Simulating Cognitive Complexity in Work Systems

Abstract

The Brahms Generalized Überlingen Model (Brahms-GÜM) is a cognitive-behavioral simulation of aviation work practices that reveals how normally complicated situations become cognitively complex for people in a dynamic environment of malfunctioning tools and non-routine workload. Brahms-GÜM was developed by analyzing and generalizing the roles, systems, and events leading to an aircraft collision, a scenario that can be simulated as a particular configuration of the model. Brahms-GÜM demonstrates the strength of the Brahms framework for simulating behaviors of asynchronous (or loosely coupled), distributed processes in which the sequence of spatial-temporal interactions can become mutually constrained and unpredictable.
