A Conceptual Model of Human Workflows

The ability to understand human workflows is crucial for information systems to monitor and support people performing real-life activities, such as preparing a meal to performing a medical procedure. This paper introduces a conceptual model to capture the knowledge necessary for computers to make sense of human workflows. A computational model based on behavior trees is presented to represent human workflows in a hierarchy of abstraction levels, and a 3d simulation platform is developed to validate the model independent of supporting infrastructure.
